P. 60 1 Description of the unit 1.1 Package • 1 package: Outside unit • 1 package: hydraulic module and outdoor sensor 1.2 Definitions Split: The heat pump consists of two elements (an outside unit for outside and a hydraulic module for inside the dwelling). Air/water: The surrounding air is the energy source. This energy is transmitted to the water in the heating circuit by the heat pump. Inverter: the fan and compressor speeds are modulated according to the heating requirements. This technology enables you to save on energy and operate on a single-phase power supply, whatever the heat pump’s output, by avoiding heavy intensities on start-up. COP (coefficient of performance): this is the relationship between the energy transmitted to the heating circuit and electrical energy consumed.

The heat pump consists of four main elements, in which a refrigerant fluid (R410A) circulates. - In the evaporator (rep. 13, fig 7, page 11): The energy is taken from the surrounding air and is transmitted to the refrigerant. - Because it has a low boiling point, it changes from the liquid state to the vapour state, even in cold weather (down to -15 °C outside temperature). - In the compressor (rep. 10, fig 7, page 11): The vaporised refrigerant brought to high pressure and takes on more calories. - In the condenser (rep. 15, fig 8, page 12): The energy in the refrigerant is transmitted to the heating circuit. The refrigerant returns to liquid state. - In the expansion valve (rep. 9, fig 7, page 11): The liquefied refrigerant is brought back to low pressure and returns to its initial temperature and pressure. The heat pump is equipped with a controller, which controls the internal temperature based on the outside temperature measurement and governed by the temperature control. The room thermostat (optional) provides a corrective action for the temperature control The hydraulic module is equipped with an electric back-ups system, which is triggered to provide additional heat during the coldest periods. Regulation functions - The heating circuit’s initial temperature is controlled by the temperature control. - The power of the outside unit is modulated according to initial heating temperature via the “inverter” compressor. - Control of the electric back-up heating. - The daily timer program enables you to define the periods for comfortable or reduced ambient temperature. - Summer/winter mode switchover is automatic. - Control of the supplementary boiler* (the electric back-ups are deactivated). - The room thermostat* (optional) provides a corrective action for the temperature control - Control of a second heating circuit*. - Domestic hot water: Heating time programme, control of the operation of the DHW circulation pump. - Control of swimming pool heating*. Protection functions - Anti-legionella cycle for domestic hot water. * If the heat pump is equipped with optional equipment and the associated kits.

Two domestic hot water (DHW) temperatures can be parametered: comfort temperature (line 1610 to 60 °C) and reduced temperature (line 1612 to 40 °C). Setting for reduced temperature can be useful to prevent the DHW from switching on too often and for too long during the day. The production of domestic hot water (DHW) is triggered when the temperature in the tank falls 7°C (setting from line 5024) below the set temperature. The heat pump produces the domestic hot water, which is then supplemented, if required, by electrical backup heating from the tank. Depending on how the parameter (1620) is set, comfort temperature can be reached 24h/day or only at night or depending on the heat pump programme. If the contract concluded with the energy provider includes a subscription to day/night tariff, the electrical backup is subordinate to the supplier’s power tariff and the comfort temperature may only be reached at night. If no particular contract is concluded, the comfort temperature can be reached at any time, including during the day The production of DHW takes priority over heating; nevertheless the production of DHW is controlled by cycles that control the times assigned to the heating and the production of DHW in the event of simultaneous demand. A DHW “ boost” function is available on the front of the user interface (see ref. 1, fig. 39, p 31). This DHW boost enables the DHW to be heated to the comfort temperature at any time during the day. The boost function is cancelled automatically when the demand for hot water has been met. If the heating installation is equipped with a DHW circulation pump, the pump’s operation during DHW cycles can be parametered. Anti-legionella cycles can be programmed.

maintenance conditions The appliance must be installed and the maintained by an approved professional in accordance with the prevailing regulations and code of practice, in particular: The legislation on the handling of refrigerants. 2.2 Unpacking and reservations 2.2.1 Receipt Carefully check, in the carrier’s presence, the general appearance of the appliances and check that the outside unit is not laid on its side or back. In the case of any dispute, state any appropriate reservations to the carrier in writing within 48 hours and send a copy of this letter to the After-Sales service. 2.2.2 Handling The outside unit should not be laid on its side or back during transport. Laying the unit down during transport is likely to damage the internal tubes and the compressor suspensions. Any damage caused by transportation of the unit lying down is not covered by the warranty. If necessary the outside unit may be tilted only during manual handling (to go through a door or use a staircase). This operation must be conducted very carefully and the appliance must be immediately restored to upright position. 2.2.3 Accessories provided Accessories provided with the outside unit (figure 10). Accessories provided with the hydraulic module (figure 11) 2.3 Installation position The choice of the position for installation is particularly important insofar as any later movement is a delicate operation requiring the intervention of a qualified person. Choose the site of the outside unit and the hydraulic module after discussion with the customer. Observe the maximum and minimum distances between the hydraulic module and the outside unit (Figure 13); the guarantee of the performances and the system’s service life depend on this. 2.4 Installation of the outside unit 2.4.1 Installation precautions
The outside unit must only be installed outside (outdoors). If a shelter is required, it must have broad openings on the 4 walls and observe the installation clearances (fig. 12). • Choose a site that is preferably sunny and sheltered from strong cold predominant winds (mistral, tramontana, etc…). • The unit must be easily accessible for future installation and maintenance work (fig. 12). • Ensure that it is possible to make the connections to the hydraulic module easily. 14 Installation and operating manual “1350-EN” Heat pump, Split, single service 1 3 2 4 Figure 10 - Accessories provided with the outside unit 8 5 6 7 Figure 11 - Accessories provided with the hydraulic module 1 Elbow For draining away the condensates 2 Plug (x 2) (Depending on the model) 3 Flexible i n s u l a t i o n plate For filling the empty space at the input to the interconnection cable 4 Hex / Allen key To open the valves 5 Bracket To secure the hydraulic model 6 Outdoor sensor To monitor the outside temp 7 1/2" - 5/8" and/or 1/4" - 3/8" adapter To connect the flared connection and the hydraulic model 8 Nut (1/2" and/or) 1/4"

You can let this defrosted water run off over a gravel or sand bed or a concrete slab with a diamond point and a sinkhole in the ground. If the installation is in an area where the temperature can be lower than 0°C for a long period, check that the presence of ice does not present any danger. A drainage pipe can also be connected to outside unit (see § 2.4.3, page 16). • Nothing should obstruct the air circulation through the evaporator and from the fan (fig. 12). • Keep the outside unit away from heat sources and inflammable products. • Make sure the appliance not disturb the surrounding area or users (noise level, draught generated, low temperature of the air being blown out, with the risk of freezing plants in its path). The surface receiving the outside unit must be able generally to support its weight; provide a solid fixing and do not transmit any vibration to the dwelling.

your retailer (Atlantic). 2.4.2 Outside unit positioning The outside unit must be raised at least 50mm above the ground. In snowy areas, this height must be increased (figure 14) Fasten the outside unit by means of screws and rubber tightening or toothed lock washers to avoid their coming loose. 2.4.3 Condensate drain hose (see figure 14). If the use of a discharge pipe is imperative: Use the elbow provided (C) to connect a 16mm-diameter hose for draining away the condensate. Use the stopper or stoppers provided (B) to block the opening of the condensate tank. Allow for the condensate to flow away under the force of gravity (waste water, rain water, gravel bed).
If the installation is made in an area where the temperature can be lower than 0°C for a long period, provide the drain pipe with a trace resistance to avoid it icing up. The trace resistance must heat not only the pipe but also the bottom of the appliance’s condensate collection tank. 16 Installation and operating manual “1350-EN” Heat pump, Split, single service PAC Unité extérieure PAC Module hydraulique D L mini 5 m Figure 13 - Pipe diameters (in inches) and permissible lengths (in metres) Heat pump Gas and fluid conduits model Gas Fluid M i n i m u m length (L) *Maximum length (L) **Maxi level difference (D) 050 065 1/2" ¼" 0 10 15 080 5/8" ¼" 5 15 20 095 128 155 5/8" 3/8" 5 20 30 * : Without additional charge of R410A ** : Taking into account the possible additional load of refrigeration fluid R410A (see § 2.7.3, page 22).

Comply with the legislation for handling refrigeration fluids. 2.6.1 Rules and precautions • After every intervention on the refrigeration circuit and before final connection, take care to replace the plugs in order to avoid any pollution from the refrigeration circuit. • Tools Set of manometers with hoses exclusively reserved for HFCs (Hydrofluorocarbons). Vacuum pump specially for HFCs. Provision on using tools that have been in contact with HCFCs (R22 for example) or CFCs. Use of a traditional vacuum pump is authorized if, and only if, it is fitted with a non-return valve on the suction side. The manufacturer declines any liability with regard to the guarantee if the above instructions are not observed. • Flared connections
Lubrication with mineral oil (for R12, R22) is forbidden. - Only lubricate with polyolester refrigeration oil (POE). If POE is not available, fit without lubrication. • Brazing on the refrigeration circuit (if necessary) - Silver brazing (40% minimum recommended). - Brazing only under dry nitrogen internal flux. • To eliminate any filings in the pipes, use dry nitrogen to avoid introducing any humidity that may adversely affect the appliances operation. In general, take every precaution to avoid humidity penetrating into the appliance. Proceed to insulate the gas and liquid pipes to avoid any condensation. Use insulating sleeves resistant to temperatures over 120°C. In addition if the humidity level in the areas where the refrigeration pipes pass risks exceeding 70%, protect the pipes with insulating sleeves. Use a sleeve thicker than 15mm if the humidity reaches 80%, and a sleeve thicker than 20mm if the humidity exceeds 80%. If the recommended thicknesses are not observed under the conditions described above, condensation will form on the surface of the insulation material. Lastly, take care to use insulating sleeves whose thermal conductivity is 0.045 W/mK or less when the temperature is 20°C. The insulation must be impermeable to resist the passage of steam during the defrosting cycles (fibreglass wool is prohibited). 2.6.2 Refrigeration connections The outside unit must be connected to the hydraulic module with copper pipes and connections (refrigeration quality), insulated separately. Comply with the pipe diameters and the permitted pipe lengths (figure 13). The minimum length of the refrigeration connections is 5m for correct operation. The appliance will be excluded from guarantee if it is used with refrigeration connections less than 5m long. Manipulate the pipes and take them through walls with protective plugs in place. If the distance between the outside unit and the hydraulic module exceeds the length of the maximum conduits indicated in the table, an additional charge of R410A must be loaded. The quantity of R410A added must be adapted to the length of the refrigeration circuit in order to the heat pump’s performance without damaging the compressor (figure 23). 2.6.3 Creating the flarings - Cut the pipe to an appropriate length with a pipe-cutter without deforming it. - Carefully deburr it, holding the pipe towards the bottom to avoid introducing filings into the pipe. - Remove the flared connection nut situated on the valve to be connected and slip the pipe into the nut. - Proceed to flare, letting the pipe overflow the flaring tool. - After flaring, check the condition of the working radius (L). This must not show any scratch or trace of any fracturing. Also check the dimension (B). 18 Installation and operating manual “1350-EN” Heat pump, Split, single service B L C L B 0 - 0,4 C 6,35 (1/4”) 15,88 (5/8”) 1,8 2 → 2,9 3,1 → 9,1 19,7 17 29 9,52 (3/8”) 2,5 2,7 → 13,2 22 12,7 (1/2”) 2,6 2,9 → 16,6 26 Ø Hose Dimensions in mm Flaring tool Hose Flare nut Figure 18 - Flaring for flare connections

The refrigeration pipes must be shaped only on a bending machine or with a bending spring in order to avoid any risk of crushing or breaking them.
Warning • Remove the insulation material locally to bend the pipes. • Do not bend the copper to any angle over 90°. • Never bend pipes more than 3 times in the same position otherwise traces of fracturing may appear (from strain-hardening the metal). 2.6.5 Connecting the flared connections
The small pipe must always be connected before the large one.
Take particular care positioning the tube opposite its connector so as not to risk damaging the threads. A carefully aligned connector can be fitted easily by hand without much force being required.
The refrigeration circuit is very sensitive to dust and humidity: check that the area around the connection is clean and dry before removing the plugs protecting the refrigeration connectors.

This operation is reserved for installers familiar with the legislation for handling refrigeration fluids.
Creating a vacuum with a vacuum pump is essential.
Never use equipment used beforehand with any refrigerant other than a HFC. 2.7.1 Creating a vacuum and filling the refrigeration connections with gas (see figure 22). - Remove the protective plugs (B) from the charging hole (Schrader) in the gas valve (large diameter). - Connect the blue hose (on the side with a valve pusher in good condition) from the set of manometers (manifold). - Connect the yellow hose to a vacuum pump and open the blue valve on the set of manometers. - Create a vacuum until the residual pressure in the circuit falls below 0.01 bar. - Let the pump continue to operate for another 15 minutes after reaching the vacuum. - Close the blue valve on the set of manometers and then stop the vacuum pump w ithout disconnecting any of the hoses in place. - Wait 10 minutes. If the pressure rises during this 10-minute period, there is a leak in the circuit. Trace it and repair it: then start again. When the pressure has remained stable for 10 minutes after the vacuum pump stops, the circuit is considered to be gas-tight. - Remove the access plugs (A) from the valve controls.
If an additional charge is requires, add the additional charge before filling the hydraulic module with gas. Please refer to the section (“Additional charge”, page 22). - First of all fully open the small valve and then the large one using a hex key (counterclockwise direction) without forcing excessively against the stop. - Remove the blue hose rapidly. - Refit the 2 plugs and tighten them to the recommended tightening torque (see figure 21). The outside unit does not contain any additional refrigerant, enabling the installation to be purged. Flushing is strictly forbidden. 2.7.2 Sealing test Once the refrigeration circuit has been gassed as described above, check that all the refrigeration connectors are gas-tight: 6 connectors for models 050 and 065, 5 connectors for model 080 and 4 connectors for models 095, 128 and 155. The sealing test must be performed with an approved gas detector. If the flarings have been made correctly, there should be no leaks. If there is a leak, make the connection again.

The charge in the outside units corresponds to the maximum distances between the outside unit and the hydraulic module defined in Figure 13. If the distances are greater, an additional charge of R410A is required. The additional charge depends on the distance between the outside unit and the hydraulic module for each type of appliance (Fig. 23) The additional charge of R410A must necessarily be made by an approved refrigeration engineer. • Example for a heat pump model 155 An outside unit 32m away from the hydraulic module will require an additional charge of: Additional charge = (32 - 20) x 40 = 480 g The charge must be introduced after creating the vacuum and before the hydraulic module is filled with gas, as follows: - Disconnect the vacuum pump (yellow hose) and connect a bottle of R410A instead in the fluid extraction position. - Open the bottle’s valve. - Bleed the yellow hose by loosening it slightly on the manifold side. - Place the bottle on scales with a minimum accuracy of 10g. Note the weight. - Carefully open the blue valve slightly and check the value shown on the scales. - As soon as the value displayed has dropped by the value for the calculated additional charge, close the bottle and disconnect it. - Then rapidly disconnect the hose connected to the appliance. - Proceed to fill the hydraulic module with gas.
Warning • Only use R410A! • Only use tools suitable for R410A (set of manometers). • Always charge in the fluid phase. • Never exceed the length or the maximum difference in level. 22 Installation and operating manual “1350-EN” Heat pump, Split, single service Model 050 - Model 065 20 g of R410A per additional meter Length of the connections 10 m 15 m 20 m Additional charge none 100 g 200 g Model 080 20 g of R410A per additional meter Length of the connections 15 m 20 m 25 m 30 m Additional charge none 100 g 200 g 300 g Model 095 40 g of R410A per additional meter Length of the connections 15 m 20 m 30 m 40 m Additional charge none 200 g 600 g 1000 g Model 128 50 g of R410A per additional meter Length of the connections 20 m 30 m 40 m Additional charge none 500 g 1000 g Model 155 40 g of R410A per additional meter Length of the connections 20 m 30 m 40 m Additional charge none 400 g 800 g Figure 23 - Additional charge R410A Gas Fluid Figure 24 - Gas bottle R410A

2.8.1 General The connection must comply with good trade practice according to local building regulations. The heating circulating pump is built into the hydraulic module. Connect the central heating pipes to the hydraulic module, complying with the direction of circulation. The diameter of the pipes between the hydraulic module and the heating collector must be at least 1 inch (24x36mm). Calculate the diameter of the pipes according to the flow rates and the lengths of the hydraulic systems. Use union connectors to facilitate removing the hydraulic module. Preferentially use connection hoses to avoid transmitting noise and vibrations to the building. Connect the drains from the drain valve and the safety valve to the main sewer system. Reminder: Seal everything when fitting in accordance with prevailing trade practice for plumbing work: - Use suitable seals (fibre seals, o-rings). - Use Teflon tape or hemp. - Use sealing paste (synthetic depending on the case). The use of glycol is not necessary. If you are using a glycol/water mix, provide for an annual check on the quantity of glycol. In certain installations, the presence of different metals can cause corrosion problems; the formation of metal particles and sludge in the hydraulic circuit is then seen. In this case, it is advisable to use a corrosion inhibitor in the proportions indicated by its manufacturer. It is also necessary to ensure that the treated water does not become aggressive. 2.8.2 Rinsing out the installation Before connecting the hydraulic module to the installation, rinse out the heating system correctly to eliminate any particles that may affect the appliance’s correct operation. Do not use solvents or aromatic hydrocarbons (petrol, paraffin, etc.). In the case of an old installation, provide a sufficiently large decanting pot with a drain on the return from the boiler and at the lowest point in the system in order to collect and remove the impurities. Add an alkaline product to the water and a dispersant. Rinse the installation several times before filling it definitively. 2.8.3 Filling and purging the installation Check the pipe fixings, the tightness of the connectors and the stability of the hydraulic module. Check the direction in which the water is circulating and that all the valves open. Proceed to fill the installation. Do not operate the circulating pump while filling. Open all the drain valves in the installation and the bleed valve for the hydraulic module to remove the air contained in the conduits. Close the drain and bleed valves and add water until the pressure in the hydraulic circuit reaches 1.5 bar. If the pressure is lower than 0,5 bar, the Heat Pump stops and posts error 369. Check that the hydraulic circuit has been purged correctly. Check that there are no leaks and that the circulating pumps are not seized (if need be, release them). After the “Start-up” stage (see p. 30), once the machine has started, purge the hydraulic module again (2 litres of water).

been cut off before starting any repair work. 2.9.1 Characteristic of the electrical supply The electrical installation must be conducted in accordance with the prevailing regulations. The electrical connections must only be made when all the other fitting operations have been completed (fixing, assembly, etc.).
Warning The contract concluded with the energy provider must be sufficient not only to cover the heat pump’s power but also the combined sum of all the appliances likely to be operating at the same time. When the voltage is too low, check with your energy provider the value subscribed to in your contract. Never use a socket for the power supply. The heat pump must be supplied with power by special protected leads from the electric panel via 2-pole circuit breakers specially dedicated to the heat pump: Curve D for the outside unit, curve C for the electric heating and domestic water back-ups (see tables on page 25). The electrical installation must necessarily be equipped with a 30mA differential protection. Use a flexible cable of H07 RN-F type. This appliance is intended to operate under a nominal voltage of 230V +/- 10%, 50 Hz. 2.9.2 General remarks on electrical connections Tighten the screws on the terminal blocks perfectly. Unsufficient tightening can cause overheating, leading to breakdown or even a fire. Use cable clamps to prevent the conductors from being disconnected accidentally. Connection to Earth and Earth bonding continuity are essential. • Connecting to screw terminals Rigid wires (A, fig. 28). Rigid wires are always preferable for fixed installations, particularly in a building. - Always select a wire that complies with the prevailing standards. - Strip away around 25 mm from the end of the wire. - With round end pliers, form a loop with a diameter corresponding to the tightening screws on the terminal. - Tighten the terminal screw firmly onto the loop created. Flexible wires (B, fig. 28) H07RNF type flexible wire can be used with certain precautions: - Strip away around 10mm from the end of the wire. - With tightening pliers, fit a round tag with a diameter corresponding to the terminal screw’s diameter on the end of the wire. - Tighten the tag firmly onto the terminal with a screwdriver. - We strongly advise against using flexible wires without round tags. - Always protect the cables when passing them through cable clamps with PVC protective conduit 0.5 to 1mm thick. • Connecting to regulation cards - Remove the corresponding connector and make the connection. • Connecting to spring terminals (fig. 30) Rigid wires - Strip away around 10mm from the end of the wire. - Slide the wire into the opening provided for this purpose. - Push the spring with a screwdriver so that the wire enters the cage. - Remove the screwdriver and then check that the wire is jammed in the cage by pulling on it. Flexible wires - Use the ends and proceed as before. 24 Installation and operating manual “1350-EN” Heat pump, Split, single service 25 mm 10 mm A : Rigid wires B : Flexible wires Loop Round terminal tightened Special screw and washer Terminal block Figure 28 - Outside unit terminal block Figure 29 - Regulation connector Figure 30 - Hydraulic module terminal block

E.g.: A thermostat on the heating floor will stop the heat pump if the temperature in the floor is too high - Connect the safety component to input EX6. • 230 V on input EX6 = stoppage of heat pump (the system displays Error 369). 2.10 Outdoor sensor The outdoor sensor is required for the heat pump to operate correctly. Consult the fitting instructions on the sensor’s packaging. Place the sensor on the coldest part, generally the northern or north-eastern side. In any case, it must not be exposed to the morning sun. It must be installed so as to be easily accessible but at least 2.5m from the floor. It is essential that it avoid any sources of heat such as flues, the upper parts of doors and windows, proximity to extraction vents, the underneath of balconies and under-eave areas which would isolate the sensor from variations in the outside air temperature. - Connect the outdoor sensor to the M and B9 terminals on the heat pump control board (fig. 38, p. 29). 2.11 Room thermostat and/or remote control The room thermostat (remote control) is optional. Consult the fitting instructions on the sensor’s packaging. The sensor must be installed in the living room area on a very uncluttered wall, 1.5m above the floor. Avoid direct sources of heat (chimney/flue, television, cooking hobs), draughty areas (ventilation, door, etc.). Air leaks in the seals in the constructions are often translated into cold air blowing through the electrical conduits. Lag the electrical conduits if there is a cold draught on the back of the IR sensor.

- Connect each of the sensors to one of the CL+ or CL- terminals on the heat pump control board (fig. 38, p. 29) using the connector supplied. • Installation equipped with a room thermostat and a remote control - Connect the sensor to one of the CL+ or CL- terminals on the heat pump control board (fig. 38, p. 29). - Connect the remote control to the other CL+, CL- terminals and to G+. 2.12 Start-up - Close the installation’s main circuit breaker. On first commissioning (or in winter), in order to allow the compressor to pre-heat, engage the installation’s main circuit breaker (power supply to the outside unit) some hours before starting up the tests. - Engage the heat pump’s ON/OFF button. When the power is switched on and every time that the ON/OFF button is switched off and then switched on again, the outside unit will take approximately 4 minutes to start up, even if the setting is requesting heating. - Make all the specific adjustments to the setting (configuring the installation). - Press the key - Hold down the key for 3s and select the level of access used with the aid of the knob . - Confirm with the key - Parameter the heat pump’s setting - Consult the settings’ list (page 34). On commissioning (or the case of error 10), the electrical backup heaters are liable to start up even if the outside temperature at the time is above the heaters’ trigger temperature. The regulating system uses an average initial outside temperature of 0°C and requires some time to update this temperature. To mitigate this situation, the sensor must be connected correctly. Re-initialise parameter 8703 (implementation level, consumer diagnostic menu). 2.13 Configuring the room thermostat Room thermostat To configure the room thermostat and connect it to the appropriate heating zone: - Hold down the presence key for more than 3 seconds. The room thermostat displays RU and a number flashes. - Turn the wheel to choose the zone (1, 2).
If the installation is fitted with 2 room thermostats, - First connect one room thermostat and configure it in zone 2 - Then connect the other room thermostat and configure it as default in zone 1. - Hold down the presence key; the room thermostat displays P1 and a flashing number. 1: Automatic recording: a correction of the setting with the button is adopted without any particular confirmation (timeout) or by pressing the regime key. 2: Recording with confirmation: a correction of the setting with the button is not adopted until the regime key is pressed. - Press the presence key again; the room thermostat displays P2 and a flashing number. 0: OFF: all the operating elements are engaged. 1: ON; the following operating elements are locked: Switching over the heating circuit’s operating mode Adjusting the comfort setting Changing the operating level The room thermostat displays OFF for 3 seconds when a locked button is pressed. 2.14 Configuring remote control Remote control During commissioning, after an initialisation period of approx. 3 minutes, the user’s language must be set: Press the key “OK” Choose menu “Bedieneinheit” Choose language (Sprache) Select the language (english, français, nederlands, español, etc) 30 Installation and operating manual “1350-EN” Heat pump, Split, single service OK OK

3.3 Temperature control The heat pump’s operation is subject to the temperature control. The set temperature for the water in the heating circuit is adjusted according to the outside temperature The temperature control may be chosen automatically by the machine (self-adaptation) or set manually by the installer (Parameters 720, 721 and 726). If there are thermostatic valves on the installation, these must be fully open or adjusted for higher than the normal set temperature. 3.4 Manual adjustment During installation, the temperature control must be parametered according to the heat emitters and the dwelling’s insulation. The temperature control’ curves (Fig. 41) refer to an ambient setting of 20°C. The slope of the temperature control (parameter 720) determines the impact of the variations in the outside temperature on the initial heating temperature variations. The higher the slope, the more a slight reduction in the outside temperature causes a significant increase in the initial water temperature in the heating circuit. The off-set in the temperature control (parameter 721) alters the initial temperature of all the curves, without altering the slope (Fig. 42). The corrective actions in the case of any inconvenience are detailed in the table (Figure 43). 3.5 Self-adaptation When this function is active (parameter 726), the temperature control are automatically adjusted; it is therefore futile to alter the slope or the off-set in the temperature control (parameters 720 and 721). When this function is first activated, the end user may experience some inconvenience for a few days. This period of no more than a week is required by the regulator to determine the slope and off-set in the temperature control. We advise against changing the temperature settings during this period. The following instructions must be observed for the self-adaptation system to operate correctly: - A room thermostat must be connected. - The influence of the ambient temperature" (parameter 750) must be set between 1 and 100%. - Depending on the installation, the room thermostat may have a greater or lesser influence on the temperature control. - The room in which the room thermostat is installed must not contain any thermostatic valves. If this is the case, the valves must be open fully. 32 Installation and operating manual “1350-EN” Heat pump, Split, single service °C 10 12 13 11 Figure 40 - Room thermostat (option) Ref.
