Daikin Controller 008.1420844_13 – 02/2016 2 x Product description 2 Product description The Controller RoCon HP is part of the Daikin Altherma EHS(X/H). It consists of the RoCon BM1 control panel to which the actuators and sensors, as well as other compo- nents in the Daikin RoCon regulating system, are con- nected, and the RoCon B1 operating unit. In this instruction manual we explain just the functions and setting possibilities of the Controller. More infor- mation on the Daikin Altherma EHS(X/H) and other equipment components can be found in the supple- mentary documents. The electronic, digital Controller is able to automatically control all heating, cooling and hot water functions for a direct heating circuit, a storage tank charging circuit and optionally connectable mixer module, depending on the heating unit in question. It is responsible for all safety management functions of the Daikin Altherma EHS(X/H). This executes a safety switch-off in the event of a water shortage or undefined operating states.  A corresponding fault message shows the operator all the infor- mation for fault causes. All function settings for the Daikin Altherma EHS(X/H) and the optional RoCon devices connected via the data bus are carried out with the operating elements of the integrated RoCon B1 control panel and displayed in clear text display on a coloured backlit display. The regulation data bus can be used to connect the Daikin Altherma EHS(X/H) to the following optional equipment: – EHS157034 room station – EHS157068 mixer module. In addition, the RoCon HP control unit has a frost protection function for the direct heating circuit and the storage tank charging circuit, as well as an automatic function for heating support (inclusion of an additional source of heat such as a wood- burning boiler or solar installation). The potential-free AUX switching contact can be used to carry out different control functions in conjunction with external devices (demand from an external heat generator, switching to bivalent operating mode, external status display, etc.). In addition, it also has several inputs for assessing external control contacts (external operating mode switching or heat demand, SMART GRID- and low-tariff EVU functions(1. (1 Energy supply company (EVU) sends signals that are used for controlling the power mains loading, and which have an influence on the cost of the power and availability. The weather-controlled flow temperature regulation can be opti- mised with the RoCon OT1 optional external temperature probe which can be installed on the north face of the building. If the EHS157056 optional gateway is installed and connected to the Internet, the Daikin Altherma EHS(X/H) can be conveniently monitored and operated by remote control using a mobile phone (app). The Controller RoCon HP contains a timer which can be used to set: – 2 individually-adjustable timer programmes(2 for room heat- ing and room cooling (direct heating circuit), – 2 individually-adjustable timer programmes for hot water gen- eration, – 1 individually-adjustable timer programme for an optional cir- culation pump. (2 Use of the timer programme for room cooling only possible in combination with a connected room thermostat Initial commissioning of the heating system is described in the in- stallation manual for the Daikin Altherma EHS(X/H). Certain menu items in the Controller RoCon HP are only acces- sible to the specialist heating technician. This security measure ensures that no undesirable malfunctions arise during operation of the system through incorrect settings. The EHS157034 room station has the same operating panel as the Daikin Altherma EHS(X/H) B1 operating element integrated in the RoCon B1. All settings for the allocated heating circuit can be carried out in the same way as the operating unit. With activated terminal function, all operating possibilities that are available on the inte- grated operating unit are available, with the exception of certain special functions (e.g. Manual Operation). An EHS157068 connected mixer module will also be operated, after appropriate allocation, by the RoCon B1 control unit and/or the EHS157034 room station.

If electrical components come into con- tact with water, this can cause an elec- tric shock as well as potentially fatal injuries and burns. ● The displays and the buttons on the Controller must be protected from the effects of moisture. ● To clean the Controller use a dry cotton cloth. Using aggressive cleaning agents and other liquids can cause damage to equipment or lead to an electric shock. Maximum energy utilisation The most effective energy utilisation is achieved by the Daikin Altherma EHS(X/H) at the lowest possible return flow and hot water temperatures. If an external heat generator (e.g. the optional Backup Heater) is used at inflow target temperatures of over 50 °C, the efficiency (COP) of the Daikin Altherma EHS(X/H) can be affected negatively  (depending on the outside temperature). 3.2 Display and operating elements 1 Clear text display 2 Setting: Configuration 3 Setting: Remote Param 4 Rotary switch 5 Setting: Info 6 Setting: Operating Mode 7 Setting: Set Temp Day 8 Setting: Set Temp Night 9 Setting: DHW Set Temp 10 Rotary button 11 Setting: DHW Install 12 Setting: Time Program 13 Exit button Fig. 3-1 Arrangement of display and operating elements

In normal operating mode the rotary switch should be in position . After switching on and successful initialisation, the display auto- matically shows the standard display with rotary switch position . In the first commissioning, the setting for language selection is displayed first. ● Select the language using the rotary switch. ● Confirm the changes with a brief push of the rotary switch. Adaption to the special installation configuration is carried out in the "Configuration" rotary switch position (see section 3.4.8). When the system is switched on, based on the stipulations set in the Controller RoCon HP, it fully automatically regulates the operation of the – room heating, room cooling and the – sanitary hot water generation. Independent of the setting of the rotary switch, the Daikin Altherma EHS(X/H) operates in accordance with the operating mode set in the "Operating Mode" switch position or that has been activated by a special programme. If the user enters a value manually, this setting remains active until the user changes it or until the programme clock forces an- other operating mode.

Keylock Function On Keylock Function Keylock Function Off Fig. 3-4 Activating button lock (1.) and deactivating (4.) 3.4 Basic functions and operating modes If the storage temperature falls below a certain minimum value, the safety settings of the Daikin Altherma EHS(X/H) prevent the operation of the heat pump in the case of low external temperatures: – External temperature < -2 °C, minimum storage temperature = 30 °C – External temperature < 12 °C, minimum storage temperature = 23 °C. Without backup heater: The storage tank water must be heated to the minimum required storage temperature by an external heater. With backup heater (EKBUxx): With an outdoor temperature < 12 °C and a storage tank temperature < 35 °C, the backup heater (BUH) is switched on automatically on in order to heat up the storage tank water to at least 35 °C. ● In order to accelerate the heating process with the back-up heater, temporarily – Parameter [Function Heating ] = "1" and – Set parameter [Power DHW] to the maximum value of the back-up heater. – Set rotary switch to the operating mode and parameter [1x Hot Water] to "On". Automatic defrosting function At low outdoor temperatures and corresponding humidity values, the external heat pump unit may ice up. This icing impairs effi- cient operation. The system detects this condition automatically and starts the defrosting function. During the defrosting function, heat is drawn from the hot water storage tank and the backup heater is turned on if required.  Depending on the heat demand for the defrosting function, heating of the direct heating circuit may be interrupted tempo- rarily. After 8 minutes at most, the system returns to normal mode. 3.4.1 System information (Info) In this rotary switch position, the rotary switch can be used to call up all the system temperatures, the type of Daikin Altherma EHS(X/H), various software information and the oper- ating statuses of all system components, one after the other.  The number of displayed parameters depends on the connected components.

Resistances outside of this toler- ance ranges are interpreted as open input. The heat generator resets to the previously active operation mode. At resistance values higher than the value for  "Automatic 2", the input is not considered. If several switching contacts are to be connected to the Daikin Altherma EHS(X/H) (e.g. SMART GRID, Room thermostat), the associated functions can have a higher priority than the external operating mode switching.  The operating mode requested by the EXT switching contact might then not be activated or may be activated later. In addition to these operating modes there are various different temporary heating programmes available (see tab. 3-7), which run according to priority after they have been activated.

The call-up of special functions does not depend on the setting on the rotary switch. ● Depress the exit button for at least 5 secs.  Menu "Special Level" is displayed. ● Select the programme to be started with the rotary switch. ● Confirm the changes with a brief push of the rotary switch.  The selected programme starts. ● Cancellation and jump back by: – Pressing the exit button again, or – Briefly pressing the rotary switch or – selecting a different menu using the rotary switch. 3.5.1 Manual Operation Manual Operation is used to regulate the Daikin Altherma EHS(X/H) manually to a specific flow temperature.  The manual mode should only be used for diagnostic purposes. With hydraulically controlled priority operation for the hot water generation you must make sure that the inflow target temperature set in manual mode is adequate to achieve the stored hot water set temperature (parameter [T-DHW Setpoint 1]). ● Depress the exit button for at least 5 secs.  Menu "Special Level" is displayed. ● Select the programme "Manual Operation" with the rotary switch. ● Confirm the changes with a brief push of the rotary switch.  "Manual Operation" active. ● Set the inflow target temperature with the rotary switch. Do not confirm the setting with the rotary switch, as this will close the programme.  During active manual mode the hot water is consistently regulated to the parameter value for the first target hot water temperature ([T-DHW Setpoint 1]).  The button block (if it was activated from the start of this function), is activated again within 2 seconds in order to prevent inadvertent termination of the function by operat- ing the Controller RoCon HP. ● Cancellation and jump back by: – Pressing the exit button again, or – Briefly pressing the rotary switch or – selecting a different menu using the rotary switch.  If the manual mode is closed, the Controller RoCon HP automatically switches to the operating mode "Standby".

The two 3-way diverter valves are always automatically moved, on days of the week "Monday", "Wednesday" and "Friday", by 11:00 in each case, to their base position (bypass - way AB-A open). This function can take up to 5 minutes. It is rigidly programmed and cannot be changed. 3.6 Special system settings The Controller RoCon HP already has the basic configuration for the Daikin Altherma EHS(X/H). However, it needs to be adapted to the optionally connected accessories and the installation envi- ronment during initial commissioning. Adaption is carried out via the setting of parameters in the rotary switch setting "Configuration" . Navigating with the rotary switch accesses either the next deeper level or directly to the appropriate parameter. 3.6.1 Access Rights (Technician password) Certain settings are restricted by Controller access rights.  In order to gain access to these setting values (parameters) you need to enter the expert "Setup" code in the level. The fig. 3-13 shows the fundamental procedure for entering the access code. The expert code will be advised to the expert company in a separate letter.

Daikin Controller 008.1420844_13 – 02/2016 3 x Operation 3.6.2 Heat curve Caution - danger of overheating with underfloor heating! In the event of a fault, or in hand mode, damage may be caused to the screed, the structure of the floor and the under- floor heating system by overheating. ● Before initial commissioning of the underfloor heating system, set the maximum permissible system temperature Controller RoCon HP (parameter [T vbh1 max]) in the maximum temperature limit in the Control RoCon HP (parameter [Max T-Flow]). ● Connect the overheat protection switch (customer) on the "EXT" plug connection to the external operating mode switch so that the Daikin Altherma EHS(X/H) is in operating mode "Standby" or "Summer"  (see section 3.4.2). In parameter [Room thermostat] = On or parameter [Interlink fct] = On, the overheat protection switch must be connected so that the switching con- tact of the room thermostat is inter- rupted. ● If the underfloor heating system is also used for room cooling, the connection notes from the previous section are also valid for the connection of a customer-provided humidity protection switch. With the heating characteristic curve, the inflow target temper- ature is adjusted to building conditions in accordance with the rel- evant external temperature (weather-controlled flow temperature regulation, see section 3.6.4). Generally speaking, the steepness of the heating characteristics describes the ratio of the flow tem- perature change to the external temperature change. The heating characteristic curve applies within the minimum and maximum temperature limits that have been set for the corre- sponding heating circuit. The room temperature measured in the living area may differ from the desired room temperature; these deviations can be kept to a minimum by installing a room station or a room thermostat. The Controller is configured in the factory so that the heating curve does not adjust itself during operation. The automatic heat curve adaptation can be activated  (parameter [HC Adaption]) if the room station (EHS157034) is connected (see section 3.6.4). Starting conditions for the automatic heating curve adaption: – Outdoor temperature < 8 °C – Operating mode is automatic (I or II) – Duration of setback phase at least 6 hours If an automatic heat curve adaption is not activated, the heat curve can be set manually by adjusting the parameter [Heat- Slope]). Manually adjusting the heating curve Do not make any corrections to the set values for 1 - 2 days, and then only make them in small increments. ● Deactivate additional heat sources (e.g. fireplaces, direct solar radiation, open windows). ● Fully open any existing radiator thermostat valves or setting drives. ● Activate the operating mode "Heating". Approximate setting values: – Radiator: 1.4 to 1.6. – Underfloor heating system: 0.5 to 0.9.

In the event of a fault or wrong setting of parameters, damage may be caused to the screed, the structure of the floor and the underfloor heating system by con- densation. ● Before initial commissioning and activation of cooling operation, set the maximum permissible system temperature in the minimum temper- ature limit in the Controller RoCon HP (parameter [Min T-Flow Cooling]). With the cooling characteristic curve, the inflow target temper- ature is adjusted to suit building conditions in accordance with the relevant external temperature (weather-controlled flow temper- ature regulation, see section 3.6.4). Warmer outdoor tempera- tures result in a colder inflow target temperature and vice versa. Conditions for cooling operation: – Outside temperature > target room temperature setting – Outside temperature > [Start T-Out Cooling] parameter set- ting – Operating mode "Cooling" activated. a) with the rotary switch in the "Operating Mode" position or b) via the room thermostat function (cooling switching contact closed) – No heating demand in the RoCon system of the heating installation.

Daikin Controller 008.1420844_13 – 02/2016 3 x Operation The cooling characteristic curve is specified using the following four parameters: 1. [Start T-Out Cooling] 2. [Max T-Out Cooling] 3. [T-Flow Cooling start] 4. [T-Flow Cooling max] During the weather-controlled flow temperature regulation, the user can adjust the inflow target temperature using the parameter [Cooling Setpoint adj] by a maximum of 5 K up or down.  The lower temperature limit is limited by the parameter [Min T- Flow Cooling]. 1 Parameter [Start T-Out Cooling] 2 Parameter [Max T-Out Cooling] 3 Parameter [T-Flow Cooling start] 4 Parameter [T-Flow Cooling max] 5 Parameter [Min T-Flow Cooling] 6 Target room temperature 7 Cooling operation possible TA External temperature TV Flow temperature ― Cooling characteristic curve --- Possible parallel dis- placement of the cool- ing characteristic curve Fig. 3-16 Parameter-dependency of characteristic cooling curve More detailed explanations and possible setting values for this function can be seen in chapter 6.2.3. If the average outdoor temperature, with the activated operating mode "Cooling", falls below 4 °C, the operat- ing mode automatically switches to "Heating". Automatic switching of the operating mode to "Cooling" again can only take place if: – a room thermostat is connected to the plug connec- tion J16 (cooling ) and – the switch contact on the room thermostat is closed and – the average outdoor temperature is over 10 °C again. 3.6.4 Weather-controlled flow temperature regulation If the weather-controlled flow temperature regulation is active, the inflow target temperature (see info parameter [T-HS Set- point], section 6.10) is determined automatically in accordance with the set heating/cooling curve depending on the outside tem- perature. In delivery status, this function is activated. It can only be deacti- vated or reactivated with the technician code (set point control). The weather-controlled flow temperature regulation can be opti- mised with the RoCon OT1 optional external temperature probe, which can be installed on the north face of the building. If no RoCon OT1 is installed, the Controller RoCon HP uses the value for the outside temperature measured in the exterior heat pump unit. If the room station (EHS157034) is additionally connected to the Daikin Altherma EHS(X/H), the inflow target temperatures will be controlled dependent on the weather and room temperature  (see tab. 6-3 / tab. 6-16, parameter [Room Influence]). Activation and deactivation of this function takes place via the parameter [HC Function] in the rotary switch position "Configuration" in level "HC Configuration". – Parameter [HC Function] = 0: Weather-controlled flow tem- perature regulation – Parameter [HC Function] = 1: Regulation according to fixed inflow target temperature – In heating mode: parameter [T-Flow Day] or parameter [T-Flow Night] – In cooling mode: parameter [T-Flow Cooling] The weather-controlled flow temperature regulation has no influence on the set flow temperature in the event of a demand from the hot water circuit. If a mixer module is connected The setting of the heating/cooling curves and the activation of the weather-based flow temperature regulation for the assigned heating circuit is performed in the same way as described above. There is the option of operating the assigned heating circuit as a a) Mixer extension The outside temperature determined by the outside temperature sensor connected to the Daikin Altherma EHS(X/H) is transmitted to the mixer module via the CAN bus. or as b) Mixer extension with zone regulation  A separate outside temperature sensor (RoCon OT1) must be connected to the mixer module. The assigned heating cir- cuit is regulated based on the relevant outside temperature for this zone. When the terminal function is activated, the mixer module is op- erated via the RoCon B1 control element of the Daikin Altherma EHS(X/H), and the settings for the assigned heating circuit are performed. In conjunction with the EHS157034 room station, the mixer module can also autonomously control the assigned heating circuit, fully independently of the Daikin Altherma EHS(X/H). If the message "n. A." is displayed at the rotary switch setting , the control unit has yet to be assigned a valid terminal address. If the message "n. A." is still displayed it may be nec- essary to update the device software before the ter- minal function can be used. Contact the Daikin Service Team in such cases. More detailed explanations and possible setting values for this function can be seen in sections 6.2.3 and 6.13.2. 3.6.5 Frost protection function If the outdoor temperature is below the parameter value [T-Frost Protect], the integrated heating circulation pump is switched on in order to prevent the heating system from freezing. In addition, the inflow, storage tank and connected room temper- ature sensors are continually monitored. If the temperature measured by any of these sensors drops below 7°C (in the case of room temperature: 5 °C), the frost protection function is auto- matically activated.

Daikin RoCon HP Daikin Controller 008.1420844_13 – 02/2016 Operating instructions 25 When the frost protection function is active, the Controller RoCon HP standard display shows the symbol alongside the time. If the inflow heating temperature drops below 7 °C, the Daikin Altherma EHS(X/H) heats up until the temperature reaches at least 12 °C once more. The function ceases once the outside temperature has risen to the set parameter value [T-Frost Protect] + 1 K is reached and there are no other activation conditions present. Off-peak tariff activated; – parameter [HT/NT Function] = 3  or – parameter [SMART GRID] = 1, the heat pump operation can be completely switched off by the energy supply company for a limited period of time. In such cases, no additional heating is carried out and the internal device heating circulation pump is not switched on, even in frost-protection conditions. These situations can arise when the "Overview" infor- mation level (see section 3.4.1) in the operating data field "Ext" displays the value "HT" or "SG1". 3.6.6 Interlink function Caution! Incorrect flow temperatures can result in damage to the underfloor heating sys- tem or the build-up of condensation on cooling surfaces. ● Limit infeed target temperatures to suitable ranges. ● Heat distribution areas with different design temperatures should be installed as hydraulically separate heating circuits. Heating circuits with limited infeed tar- get temperatures should possibly be installed as mixing circuits controlled by mixer modules. Setting of the parameter [Interlink fct] = On offers the possibility of the Daikin Altherma EHS(X/H) integrating two different infeed target temperatures into the control system. This applies both to a weather-controlled controller and a con- troller using a fixed inflow target temperature (see section 3.6.4). A possible use for this might be the additional integration of aFWXV(15/20)AVEB in a surface heating and cooling system. Requirement: 2 switching contacts (e.g. room thermostats) need to be connected to plug connection J16 on the Daikin Altherma EHS(X/H). – Parameter [Interlink fct] = Off: deactivated – Parameter [Interlink fct] = On: Evaluation of and cooling switching contacts at plug connection J16 on the RoCon BM1 circuit board. Activation of cooling mode only possible by changing operat- ing mode to "Cooling" (see section 3.4.2). Setting for the parameter [Room thermostat] no longer evalu- ated. a) Open switching contacts: only frost protection active. b) Operating modes "Heating" or "Automatic 1" /  "Automatic 2" active during switching cycles in day mode. – Closed switching contact heating = IL1:  The system operates according to the normal infeed tar- get temperature according to the parameter settings in "HC Configuration" > "Heating". – Closed switching contact cooling = IL2:  The system operates according to the increased inflow target temperature (normal inflow target temperature + value of parameter [T-Flow CH adj]. Priority if both switch- ing contacts are closed. c) "Cooling" operating mode active. – Closed switching contact heating = IL1:  The system operates according to the normal infeed tar- get temperature according to the parameter settings in "HC Configuration" > "Cooling". – Closed switching contact cooling = IL2:  The system operates according to the reduced inflow tar- get temperature (normal inflow target temperature - value of parameter [T-Flow Cooling adj]. Priority if both switch- ing contacts are closed. More detailed explanations and possible setting values for this function can be seen in chapter 6.2.1. 3.6.7 Additional alternative heat generator The heat supplied by an alternative heat generator must be added to the unpressurised storage tank water in the Daikin Altherma EHS(X/H) hot water storage tank. – In the case of the optional backup heater EKBUxx, this is managed by the construction. – In the case of using an external heat generator (e.g. gas or oil boiler) this can be integrated hydraulically a) unpressurised via connections (solar infeed and solar return) of the hot water tank or b) in device types Daikin Altherma EHS(X/H)B, via the integrated solar pressure heat exchanger. Adjustment of the [Function Heating ] sets whether and which ad- ditional heat generators (WEZ) are available for domestic hot water generation and heating support. – 0: No additional WEZ – 1: Optional backup heater EKBUxx (connected via XBUH1 plug) – 2: Alternative WEZ takes over the hot water generation and heating support. To demand from the heat generator, relay K3 on the RTX-EHS circuit board is switched on. – 3: Alternative WEZ 1 (optional backup heater EKBUxx) takes over hot water generation and alternative WEZ 2 takes over heating support To demand by WEZ 1 and WEZ 2, relay K3 and relay K1 respectively on the RTX-EHS circuit board are switched on! The operation of additional heat generators are also influenced by the setting of the parameter [Equilibrium Func.]  (see chapter 6.2.1) and the parameter [Equilibrium Temp]  (see chapter 6.2.2). More detailed explanations and possible setting values for this function can be seen in chapter 6.2.1.

Daikin Controller 008.1420844_13 – 02/2016 3 x Operation 3.6.8 Heating support If the heating support function (parameter [HZU] = On) is acti- vated, the energy in the Daikin Altherma EHS(X/H) integrated storage tank is used to take over the heating function. At a suffi- ciently high storage tank temperature, the heat pump (refrigerant circuit) remains out of use. The minimum value (THZUmin) is calculated as follows: THZUmin = Current active target hot water temperature  [T-DHW Setpoint] + parameter [TDiff-DHW CH]. Switch-on condition: Tdhw > THZUmin + 4 K and Tdhw > info parameter [T-HS Set- point] + 1 K If the switch-on condition is fulfilled, heat is taken from the storage tank for the heating system. Switch-off condition: Tdhw < THZUmin or Tdhw < info parameter [T-HS Setpoint]  (see section 3.6.4) If the switch-off condition is fulfilled, the heating support is stopped in the domestic hot water storage tank and the heat pump takes over the heating operation. Parameter [Power BIV] limits the maximum power which can be removed. Parameter [T vbh1 max] limits the maximum temper- ature which the heating system can reach. More detailed explanations and possible setting values for this function can be seen in chapter 6.2.2. 3.6.9 Special function: Switching contacts Setting the parameter [AUX Fct] changes the switching condi- tions for the AUX switching contact (toggle switch output A).  This switching contact can be used, for example, to control an ex- ternal heat generator. If one of the switching conditions is fulfilled, the potential-free switching contact changes over after the time set in the pa- rameter [AUX time] has passed. AUX switching contact (toggle switch output A) is not switched if setting = 0: Function deactivated. AUX switching contact (toggle switch output A) is switched if setting = 1: When storage tank temperature (Tdhw) ≥ value of param- eter [T-DHW 1 min]. 2: When there is a cooling or heating demand. 3: When there is a hot water demand to the Backup Heater (EKBUxx) or the configured Backup Heater is required for heating support. 4: When there is a malfunction. 5: When sensor value (TVBH) > 60°C. 6: When the outdoor temperature < parameter value [Equilib- rium Temp].  Heat pump continues to operate = parallel bivalence oper- ation. 7: When the outdoor temperature < parameter value [Equilib- rium Temp] + there is a heating or hot water demand.  Heat pump does not continue to operate = alternative bivalence operation. 8: When there is a hot water demand. 9: When outside temperature < parameter value [Equilibrium Temp] + heat demand "Room heating" (not for hot water demand). Heat pump no longer operates in room heating mode below the value set in parameter [Equilibrium Temp] - only in hot water mode. Use: An alternative bivalency operation room heating, if the boiler is incorporated hydraulically in such a way that it heats the depressurised storage tank water in the Daikin Altherma EHS(X/H) directly (connection via solar connec- tions). 10: "Multi-Oil" - if outside temperature < parameter value [Equilibrium Temp] + heat demand "Room heating" (not for hot water demand). Heat pump no longer operates in room heating mode below the value set in parameter [Equilibrium Temp] - only in hot water mode. Use: An alternative bivalency operation room heating, if the boiler is hydraulically incorporated in the flow of the heat pump. For this type of application, the frost protection function must be deactivated on the Daikin Altherma EHS(X/H) (parameter [T-Frost Protect] = Off). The frost protection must be provided via the boiler in this option. The potential-free AUX switching contact (switching output B) always closes if the heat pump is in "Cooling" mode. More detailed explanations and possible setting values for this function can be seen in chapter 6.2.2. 3.6.10 Air Purge By activating the Air Purge the RoCon HP Controller starts a de- fined sequence program with Start-Stop operation of the inte- grated heat circulation pump and various settings for the 3-way diverter valve integrated into the Daikin Altherma EHS(X/H). Existing air can leak from the automatic venting valve during the Air Purge and the heating circuit connected to the Daikin Altherma EHS(X/H) is evacuated. The activation of this function does not replace the correct venting of the heating circuit. Prior to activating this function, the heating circuit must be completely filled. 1. Enter the expert code (see section 3.6.1).  The "Setup" level is displayed after entering. 2. Select the [Air Purge] parameter using the rotary switch. 3. Confirm the changes with a brief push of the rotary switch.  The setting for the parameter is displayed. 4. Using the rotary switch, set the parameter for the function to "On" and confirm by pressing it quickly.  "Air Purge" starts (3-way diverter valves into middle posi- tion, heating circulation pump modulated - see fig. 3-17).  After the programme is completed (approx. 10 min), the Daikin Altherma EHS(X/H) switches to "Standby" operat- ing mode.

Place the rotary switch in the "Operating Mode" position and set the desired operating mode  (see section 3.4). More detailed explanations and possible setting values for this function can be seen in chapter 6.2.1. 3.6.11 Legionella protection WARNING! There is a danger of scalding at target hot water temperatures over 60°C.  This is possible when solar energy is used and when Legionella protection or SMART GRID is activated or when the domestic hot water target temperature is set higher than 60°C. ● Fit a scald-protection in the hot water distributor line (e.g. VTA32 + Screw connection set 1"). This function serves to prevent bacterial contamination in the hot water storage tank. For accurate controllers for drinking water hy- giene, refer to the national provisions. The Legionella protection function in the Daikin Altherma EHS(X/H) is deactivated when leaving the factory as the possibility of bacterial contamination is very low: – Low volume of heat exchanger (stainless steel) used for heating drinking water. – Frequent complete water replacement "first-in-first- out". – No stagnant water areas in drinking water storage. An active Legionella protection function (parameter [Anti-Le- gionella day]) involves heating the connected storage tank to a disinfection temperature 1 x a day or 1 x a week. The legionella protection function is active for an hour. The maximum hot water temperature set by the user or the heating technician is ignored when hot water is heated for disinfection purposes. A connected circulation pump is automatically switched on during thermal disinfection. Setting the parameters for legionella protection is carried out in the rotary switch setting "Configuration" in level "DHW Configuration". Using the factory settings, the storage tank is heated at 03:30 hours if the target hot water temperature is below 65°C at that time. More detailed explanations and possible setting values for this function can be seen in chapter 6.2.4. 3.6.12 Reset to factory settings (Reset) If the Daikin Altherma EHS(X/H) no longer works properly and any other cause for the malfunction cannot be detected, it may be helpful to reset all the controller settings to the factory settings. There are 3 options for this. Option 1 User access rights allow the switching time program in the "Special Level" to be reset to the factory setting according to tab. 3-9. 1. Depress the exit button for at least 5 secs.  Menu "Special Level" is displayed. 2. Select the programme "Timeprog Reset" with the rotary switch. 3.

Place the rotary switch in the "Info" position.  The message "Basic Configuration " is displayed. 7. There is now the facility either to select manual mode for the equipment individually (a) or to load the factory settings automatically (b). a) Press the rotary switch briefly.  A parameter overview is displayed at the level "Basic Configuration" and the settings can performed manually as desired according to tab. 6-14. b) Turn the Daikin Altherma EHS(X/H) off and restart it.  After the has restarted the question will be Daikin Altherma EHS(X/H)posed whether the standard configu- ration should be used. If it is confirmed with "Yes", the preset basic configuration is loaded. If the answer given is "No" the settings must be performed manually, see a). More detailed explanations and possible setting values for this function can be seen in chapter 6.12. After a reset to the factory settings via option 2 or 3, the system must be configured again by the heating tech- nician to the installation environment and all the cus- tomer-specific parameters reset. 3.6.13 Screed Program The Screed Program is intended exclusively for specified drying of newly created screed in underfloor heating systems. This op- erates the heat generator for several days according to a prede- fined temperature profile (the predefined temperature profile is based on the recommendations of the Bundesverbandes Flächenheizungen (Federal Association of Surface Heating Systems) for heating to cure the floor). The temperatures and the duration of the Screed Program can be adjusted as required, after entering the expert code, in the rotary switch setting "Configuration" in the level "HC Configu- ration" in the parameter [Screed Program]. The Screed Program is a special function and is not interrupted by any other operating mode. It can be activated only by the heating expert for the direct heating circuit and/or the op- tionally connected mixed heating circuits. Each heating circuit must be separately activated. Prior to start of the Screed Program, the parameters [Interlink fct] and [Room thermostat] must have been deactivated. In the event of a brief power failure the system contin- ues with a previously activated screed function in place of shutting down. After activation of the Screed Program (parameter [Screed] = On) all the weather-controlled regulating functions of the relevant heating circuit are switched off. The relevant heating circuit op- erates independently of the operating mode (switching times) as a constant temperature regulator. An already started Screed Program can be deactivated at any time. At the end of Screed Programs the screed function the pa- rameter is automatically set to "Off" and the heating circuit once again operates according to the currently set operating mode. Function heating Function heating verifies that the installation is fault-free for the heating engineer. A pre-prepared heating up protocol for Daikin underfloor heating can be found in the Daikin Internet portal. In this case, function heating (identical with "Heating up" in EN 1264, section 5.2) does not constitute a heating up process for drying and curing. Normally you need to carry out separate heating process to cure the floor and/or perform mechanical drying. Heating up should be carried out no earlier than after 21 days for cement screed, and no earlier than after 7 days for anhydrite screed in accordance with the details provided by the manufac- turer. The first heating up starts at a feed temperature of 25 °C, which must be maintained for a period of 3 days. Then heating is carried out at the maximum flow temperature set for the heating circuit (limited to max. 55 °C) and this is then held for a further 4 days. After the heating up process described, there is no guarantee that the screedhas achieved the moisture content required to cure the floor. You must determine the moisture content in the screed by meas- urement before laying the floor covering. Procedure in accordance with EN 1264 Part 4: The heating circuits must be checked for leaks by a water pressure test once the anhydrite and cement screeds are completed. The absence of leaks must be ensured immediately before and during screed laying. The level of the test pressure is at least 1.3 times the maximum permissible operating pressure. If there is a danger of freezing up, you must take suita- ble measures, e.g. the use of antifreeze or temperature control in the building. If antifreeze is no longer required for intended use of the installation, you must remove the antifreeze by draining it out and flushing the instal- lation with at least 3 changes of water.

At higher humidity levels in the air this can come to a complete stop under certain circumstances stop under certain circumstances. The drying out process may be acceler- atedby running the underfloor heating (curing heating) or by using measures such as mechanical drying. Every curing heating process must be commissioned, separately by the building owner as an extra service in accordance with VOB. For the flooring contractor to achieve fault-free installation, the flooring must be properly cured before work is started on the top flooring layer. The standard settings can be used to activate the combined function and curing heating programme in order to achieve a re- sidual moisture level in the screed required for curing the floor (see fig. 3-19). The residual moisture level in the screed must, however, always be checked by measurement before the floor- covering is laid. Fig. 3-19 The time sequence of the Screed Program in combined func- tion and curing heating (for legend see fig. 3-18) More detailed explanations and possible setting values for this function can be seen in sections 6.2.3 and 6.13.2. Screed Program setting and starting The Screed Program contains factory-set specifications which can, however, be individually adapted. Screed Program The day on which the screed function is activated does not count towards the runtime of the screed programme. The 1st. The day begins with the change of the day at 00:00. On the day of activation we heat the remaining time at the programme of the first day. ● Enter the expert code (see section 3.6.1).  The "Setup" level is displayed after entering. ● Using the rotary push button, select and check the param- eters [Interlink fct] and [Room thermostat] whether they are deactivated (see tab. 6-1).  Both parameters must be on "Off" before starting the screed function. ● Press the Exit key briefly.  An overview is displayed. ● Select the "HC Configuration" level with the rotary switch.  An overview is displayed. ● Select the [Screed Program] parameter using the rotary switch. ● Check the Screed Program settings and adjust to the stipula- tions provided for the screed by the manufacturer, if necessary (see fig. 3-20). – The setting range is always between 0.0 and 65 °C. – The steps are 1 °C.

There are 2 switching possibilities: a) Separate timer programme (see section 3.4.7).  The circulation pump operates according to its own timer programme. b) Together with a hot water timer programme. The circulation pump is actuated in parallel with the operating periods of the hot water timer programme. Independent of the set timer programme, the energy con- sumption of the circulation pump van be minimised by operating it on a cyclic basis. The parameter [Circl-Pump Interval] is used to set how long the circulation pump is operated within a  15-minute interval.

This means that the Daikin Altherma EHS(X/H) can be controlled remotely via mobile phone (using an App). Intuitive operation is possible.

Daikin Controller 008.1420844_13 – 02/2016 4 x Initial start-up 4 Initial start-up In addition to the commissioning instructions listed in this chapter, the specific commissioning instructions listed in the installation instructions for the Daikin Altherma EHS(X/H) must be complied with. The RoCon system offers a very wide range of application and extension possibilities. The individual RoCon system components communicate via the CAN data bus. For this reason, the circuit boards RoCon BM1 and the control units RoCon B1 of the Daikin Altherma EHS(X/H), and possibly the optional system compo- nents room station EHS157034 and mixer module EHS157068 are connected together via data bus lines. These system components must be allocated unique functional IDs, so that the data exchange and the allocation functions without any problems within the RoCon system. In many applications, nothing needs to be changed on the basic settings. The more RoCon system components that are inte- grated in the RoCon system, the more adjustments that need to be made during the initial commissioning or when extending the heating system. The allocation of the functional IDs is easiest carried out via the installation menu "Setup Wizard". Most IDs can also be adapted subsequently to the conditions by means of individual parameter settings in the specific parameter levels (see chapter 6). a) If no optional RoCon system components are connected to the Daikin Altherma EHS(X/H), in the RoCon system, just the circuit board RoCon BM1 and the integrated control unit RoCon B1 communicate with each other.  Adaption of the IDs is not necessary.  The question displayed during initial commissioning "Use standard configuration?" can be confirmed by "Yes". b) If optional RoCon system components such as EHS157034 and / or EHS157068 are connected, adaption to the IDs may be necessary. 4.1 Fundamental aspects of the IDs and authorisations in the RoCon system In the RoCon system, the following functional IDs exist, which are relevant for data exchange of the RoCon system components: ID / function System components Parameter Comments Heating circuit IDs Unique numbering of a heating circuit in the heating system in the RoCon system. A maximum of 16 heating cir- cuits can be controlled. Daikin Altherma EHS(X/H) (RoCon BM1) [Unmixed Circ Config] See tab. 6-14 Factory setting = 0 Should not normally be changed.1) Room station EHS157034 [HC Assignment] See tab. 6-1 Factory setting = Off Adaption necessary because there are dif- ferent heating circuits in the system and / or the parameter [Master-RoCon] = On Mixer module EHS157068 [HC Assignment] See tab. 6-15 Factory setting = Off Must always be adapted to the setting of the address switch (fig. 4-2). Heat generator ID Unique numbering of a heat gen- erator in the RoCon system.1) Daikin Altherma EHS(X/H) (RoCon BM1) [BUS ID HS] See tab. 6-14 Factory setting = 0 Should not normally be changed.1) Mixer module EHS157068 [Boiler Assignment] See tab. 6-15 Factory setting = 0 Should not normally be changed.1) Defines the heat generator that supplies the allocated heating circuit with heat. Terminal ID Unique numbering of a control unit RoCon B1 or EHS157034, from which a heat generator and / or a mixer module in the RoCon system can be controlled remotely. The authorisation for remote control can be allocated to up to 10 control units in the RoCon system. If remote control in the RoCon system is to be possible, then the control unit must be allocated the ID "0". Daikin Altherma EHS(X/H) (RoCon BM1) [Terminaladress] See tab. 6-1 Factory setting = Off The value should be set to "0" if at least 1 mixer module is connected in the RoCon system, and the mixer circuit is to be op- erated from the heat generator. Room station EHS157034 [Terminaladress] see tab. 6-1 or tab. 6-15 - depending on the set heating cir- cuit ID and the current operating mode Factory setting = Off The value must be set to a unique nu- merical value in the RoCon system, if the room station system components are to be remotely controlled using a valid device ID.

Daikin RoCon HP Daikin Controller 008.1420844_13 – 02/2016 Operating instructions 33 If several control units are incorporated in the RoCon system of a heating installation, additional parameter settings are relevant for this, which can be used for setting the individual functions and pa- rameters using the appropriate authorisations. On the room station EHS157034 – Parameter [RoCon U1 assign]: – The setting = "Living Room" can be used to influence the heating circuit defined by the set heating circuit ID. – The setting = "Mixing Valve" can be used to carry out all the settings for the mixer circuit defined by the set heating circuit ID. – Parameter [Master-RoCon]: If the heating circuit is set for the direct heating circuit of a  Daikin Altherma EHS(X/H), the setting = "On" can be used to activate the Master-RoCon function. In addition to the heating circuit functions, the hot water functions of the Daikin Altherma EHS(X/H) can also be operated with this room sta- tion. The activation of the Master-RoCon function can also be used for heating installations just made up of a Daikin Altherma EHS(X/H) (without heating circuit extension) and a room station, and which are to be operated primarily via the room station (see following information). If the Master-RoCon function is activated, the oper- ating mode of the heat generator is set via the room station, and this is shown in the dispay. The settings on the room station are transferred to the heat generator, but not vice versa. The room station has priority. For example, if the operating mode [Summer] is set, and subsequently, on the control unit of the Daikin Altherma EHS(X/H) the operating mode [Heating] is set, a heating circuit demand is not generated, be- cause the direct heating circuit, that is allocated to the room station by the heating circuit ID, is still in the operating mode [Summer]. The change in oper- ating mode must therefore be undertaken at the room station. On heating installations with heating circuit extensions, we recommend not activating the Master-RoCon function  (Setting = "Off") and instead using the terminal function. With all control units RoCon B1 B1 and EHS157034 – Parameter [Terminaladress]: As soon as a control unit is allocated a terminal ID (all settings with the exception of "Off"), the control unit can be used to activate the terminal function. After carrying out the [Bus - Scan], all the system components incorporated in the RoCon system can be remotely controlled using a valid device ID (caretaker authorisation). If you intend to use the terminal function in the heating sys- tem, you need to allocate the terminal ID = 0 to a control unit. Device ID Unique numbering of a heat gen- erator or mixer module in the RoCon system. Up to 16 device numbers can be allo- cated. These device numbers are detected during a [Bus - Scan] and are dis- played for identification of a remote controlled device. Daikin Altherma EHS(X/H) (RoCon BM1) [BUS ID HS] See tab. 6-14 Identical to heat generator detection. The value must not be the same as the heating circuit ID of a mixer module in the RoCon system. Mixer module EHS157068 [HC Assignment] See tab. 6-15 Identical to heating circuit ID. The value must not be the same as the heat generator ID of a Daikin Altherma EHS(X/H) in the RoCon system. The value must be the same as the setting of the address switch (fig. 4-2). Tab. 4-1 Functional IDs in the RoCon system 1) A maximum of 8 heat generators can be connected in the RoCon system via the CAN data bus. Several heat generators incorporated in the heating installation must be regarded as a special application. If necessary contact Daikin service technician.

Commissioning and during System Extensions When the Daikin Altherma EHS(X/H) or the room station EHS157034 are switched on for the first time, you are normally offered the opportunity of setting the user language. Then, on the Daikin Altherma EHS(X/H) you will be asked "Use Standard Config?". This question can normally be answered with "Yes". Only with special applications (e.g. several heat generators in the RoCon system should the answer be "No"). In this case you will be offered the parameter level "Basic Configuration", in order to be able to set the necessary adaptions (see tab. 6-14). With the room station EHS157034, after setting the user lan- guage, the installation menu "Setup Wizard" appears. Setup Wizard Fig. 4-1 Display "Setup Wizard" The items for definition of the function, the authorisation and the IDs of the of the room station in the RoCon system are requested and checked for plausibility. This prevents setting duplicate device and terminal IDs. We therefore recommend that, when extending or making changes to the RoCon system of the heating installation, you use this installation menu. For this, a room station already incorpo- rated in the heating installation must first be reset. 1. Enter the technician code (see section 3.6.1). 2. Depress the exit button for at least 5 secs.  Menu "Special Level" is displayed. 3. Select the programme "RoCon B1/U1 Reset" with the rotary switch. 4. Execute the programme by briefly pressing on the rotary switch.  The installation menu "Setup Wizard" starts. 4.3 Starting up the Daikin Altherma EHS(X/H) A precondition for initial commissioning is the completion of all preparatory installation work in accordance with the installation and maintenance instructions for the Daikin Altherma EHS(X/H). ● Turn power supply to Daikin Altherma EHS(X/H) on.  After the start phase, the operating language selector is displayed. ● Use the rotary switch to select the desired language. The operating language can be changed again at any time. ● Confirm the changes with a brief push of the rotary switch.  The message "Use Standard Config?" is displayed. ● Confirm the standard stipulation "Yes" with a brief push on the rotary switch (see also section 4.2).  The Basic Configuration of the RoCon device is loaded.  The message "Starting Up" is displayed.  The message "Initialization" is displayed.  The standard display for the current rotary switch setting is displayed. ● At the RoCon device, adjust the settings to suit the configu- ration of the heating system (see chapter 3.6). 4.3.1 Allocating the terminal ID on the control unit RoCon B1 of the Daikin Altherma EHS(X/H) If several control units are connected in the RoCon system via the data bus, you must note that the pa- rameter [Terminaladress] = 0 must be set for a heat generator. Make sure not to assign a duplicate value as the setting of the [Terminaladress] in the RoCon system. ● Enter the technician code (see section 3.6.1).  The "Setup" level is displayed after entering. ● Select the parameter [Terminaladress] with the rotary switch. ● Confirm the changes with a brief push of the rotary switch. ● Within the display, use the rotary switch to set the unique terminal address. For reasons of clarity, this control unit must be allocated the value = 0. ● Confirm the changes with a brief push of the rotary switch.  Change has been accepted. Jump back to previous dis- play. More detailed explanations and possible setting values for this rotary switch setting can be seen in chapter 6.2.1. 4.4 Commissioning optional RoCon system components 4.4.1 Mixer module EHS157068 The EHS157068 mixer module has no control unit of its own.  For configuration and operation it must be connected using a CAN bus cable to a RoCon-Controller installed in the heat gen- erator or to an EHS157034 room station. In conjunction with a room station the mixer module can also be operated as a free-standing heating circuit con- troller. To operate the mixer module directly via the control unit RoCon B1 of the Daikin Altherma EHS(X/H), it must have a terminal ID allocated to it and the terminal function will have to be activated (see chapter 3.4.9). After selection and confirming an external device, the terminal function for this device is activated and the associated standard display for this device is shown in the display. The operating component is then in terminal mode. In the rotary switch setting , the local control unit operates as a remote control for the external device. In this case all the control functions are provided and saved 1:1 as on the external equipment. For reasons of clarity, this control unit must be allocated the  value = 0.

ting , the control unit RoCon B1 has yet to be assigned a valid terminal address. If the message "n. A." is still displayed it may be nec- essary to update the device software before the ter- minal function can be used. Contact the Daikin Service Team for this. 4 x Initial start-up Daikin RoCon HP Daikin Controller 008.1420844_13 – 02/2016 Operating instructions 35 At the address switch (see fig. 4-2) a unique device ID (≥ 1) must be set for the heating circuit to be controlled by this mixer module, which must be synchronised with the (parameter [HC As- signment] of the mixer module (see tab. 4-1]).

If adaptions need to be made, the value of the parameter [Boiler Assignment] (see chapter 6, tab. 6-15) must be set to the same value as the heat generator ID of the Daikin Altherma EHS(X/H), that is intended to supply the mixer circuit of this mixer module. 4.4.4 Master-RoCon function Each room station EHS157034, whose heating circuit ID is set to a direct heating circuit, can be allocated the Master-RoCon function. ● Enter the technician code (see section 3.6.1).  The "Setup" level is displayed after entering. ● Select the [Master-RoCon] parameter using the rotary switch. ● Confirm the changes with a brief push of the rotary switch.  The setting for the parameter is displayed. ● Using the rotary switch, set the parameter for the function to "On" and confirm by pressing it quickly. All settings on the EHS157034 room station act in the same way as settings on the RoCon B1 B1 control panel for the as- signed heat generator. As a result, the functions for hot water preparation can also be re- motely operated from the room station. Since, in this setting, the control unit RoCon B1 has control over the allocated heating circuit, the settings made on the control unit of the Daikin Altherma EHS(X/H), only have an effect only on the heat generator, but not on the heating circuit (see section 4.1). 4.4.5 Caretaker function The caretaker function equates to the terminal function (see chapter 3.4.9 and section 4.1 under parameter [Terminala- dress]).

E75 E75 E75 Special Level Manual Operation FA failure Protocol Special Level FA failure Protocol Delete message Inside Unit: Address: Boiler 0 Read Protocol Fig. 7-3 Reading the protocol 7.1.3 Troubleshooting Information messages, which are displayed without red back- lighting, normally result in no permanent limitations on the op- eration of the Daikin RoCon. Messages that are displayed with an error code E.... and red back-lighting required error correction by an authorised and trained expert heating technician. For information on warning messages see section 7.3. ● Detecting and remedying the cause of the malfunction. – Contactor triggered: Nothing shown on the display in the controller. Ascertain cause of triggering the contactor and remedy fault. Start up system again.  Once the cause has been remedied, the system will resume operations as normal. – Contactor not triggered: a) No fault codes are shown but the system is not working properly. Troubleshooting and eliminating faults  (see section 7.3).  Once the cause has been eliminated, the system contin- ues to work normally. b) Fault codes are displayed as long as the fault conditions are present. Troubleshooting and eliminating faults  (see section 7.3). If the fault message is still displayed after the cause of the fault has been corrected, the system must be disconnected fromthe power supply for at least 10 in order to unlock it.  Once the cause has been eliminated, the system contin- ues to work normally.

Daikin Controller 008.1420844_13 – 02/2016 8 x Glossary 8 Glossary Ancillary heater An additional heat generator (e.g. backup heater or external heating boiler) which is part of the heating system and which helps bring the system up to the inflow target temperature in case of an insufficient or ineffective heat pumping process. Anti-legionella system Periodic heating of storage water to >60°C for preventative elimination of pathogenic bacteria  (legionella) in the hot water circuit. Backup demand Operating situation in which the desired infeed temperature cannot be reached or cannot be achieved efficiently through the heat pump process. As a result, an extra heater (e.g. backup heater) is used to support the Daikin Altherma EHS(X/H) to generate heat. Backup heater Optional electric ancillary heater for general support of the Daikin Altherma EHS(X/H) during heat gen- eration. Circulation pump An optional electrical circulation pump which permanently recirculates the hot water in the hot water pipes (feed from the tap connection back to the domestic hot water storage tank) and thus provides it at each draw-off point without delay. Circulation is particularly effective in widely branched piping net- works. In hot water distribution systems without a circulation pipe, at first the water cooled in the outlet pipe escapes during the tapping process until the outlet pipe is sufficiently heated by the hot water flowing subsequently. Control Device electronics, with which the processes for heat generation and heat distribution for the heating system are controlled. The Controller consists of many electronic components. The component that is most important to the operator is the operating element at the front of the heat generator which has operating elements (rotary switch, rotary button and Exit key) and a display. Domestic hot water  generation Operating status of the heat generator, in which heat is generated at increased temperatures and sup- plied to the hot water circuit, e.g. filling the hot water storage tank. Flow pipe Part of the hydraulic circuit that directs the heated water from heat generator to the heating surfaces. Heat exchanger A part that transfers thermal energy from one circuit to another. Both circuits are separated from each other hydraulically by a wall in the heat exchanger. Heat pumping process In a closed coolant circuit, the coolant absorbs heat from the surrounding air. Compressing this coolant results in a higher temperature which can then be transferred to the heating unit (thermodynamic circuit). Heating characteristic curve Mathematical relationship between the external temperature and the target flow temperature (synonym = heating curve), in order to achieve the desired room temperature at all outside temperatures. Hot water circuit Is the water circuit in which the cold water is heated and directed to the hot water discharge point. Low tariff mains connection (HT/NT) A special mains connection to the energy supplier, which offers various cheaper rates during so-called low-load periods for electrical current (day-, night-, heat pump current, etc.). Modulation Automatic and continuous adjustment of the thermal / pump output to the particular heat requirement, without having to switch various heating / pumping stages or cycles. Nominal output Maximum heat output given by the heat generator at certain operating temperatures under test condi- tions. Operating mode User or Controller-demanded function of the heat generator (e.g. room heating, hot water heating, stand-by, etc.). Parameter A value that influences the execution of programs or processes or defines specific states. Refrigerant A material which is used for thermal transfer in a heating system. At low temperature and low pressure, heat is absorbed and at high temperature and a high pressure, heat is emitted. Return flow Part of the hydraulic circuit that directs the cooled water from the radiators in the rooms back to the heat generator via the piping system. SMART GRID (SG) Intelligent energy utilisation for economical heating. Using a special electricity meter it is possible to receive a "SMART GRID signal" from the energy supply company. Depending on the signal from the energy supply company, the heat pump is turned off, put into standard mode or run in high-temperature mode. Switching time programme Programme for setting dates and times on the Controller to define regular heating, cooling, economy and hot water cycles. Water shortage/ overheating protection Safety device which switches off the heat generator automatically if there is a water shortage, in order to avoid over-heating. Weather-controlled flow tem- perature regulation The inflow target temperature for temperature control in the heating unit is calculated from the measured value for the external temperature and a defined heating curve.
