Installation Optigo can be mounted in a DIN-standard casing (minimum 7 modules), on a DIN-rail in a cabinet or, using a suitable front-mounting kit, in a cabinet door or other control panel. It can also be screwed to any suitable flat surface using the two screw-pockets provided. Ambient temperature: 0…50°C. Ambient humidity: max. 90 %RH, non-condensing. Wiring This section only describes general rules and technical limitations concerning the wiring. In chapter 5 there are specific wiring diagrams for the different control modes. Choose the one suitable for the application on hand. It is important to make sure that the wiring is correctly done, in accordance with the instructions given in this manual and in accordance with local legislation for this type of installation. 22 21 20 3 2 1 AO2 0...10 V DC Output AO1 0...10 V DC Output AGND Ref. for AO1 and AO2 G0 G 24 V AC supply voltage 50 44 43 42 41 AGND Ref. for AI1 and UI1 analogue UI1 0...10 V DC or Digital input UI+ Reference for UI1 digital mode DI1 Digital input DI+ Reference for DI1 51 AI1 PT1000 temp. sensor input Supply voltage 24 V AC ±15%, 50…60 Hz. 6 VA If the Optigo OP5 and active sensors and actuators connected to it share transformer, it is essential that the same transformer-pole is used as reference for all the equipment. Failure to do so will prevent the equipment from functioning as intended and may also lead to damages.

AGND All AGND terminals are interconnected and also connected to G0. Analogue input AI The analogue input must refer to an AGND terminal. The analogue input is for PT1000 temperature sensors only. Temperature range: -30…+54°C. Note: For temperatures below -9.9°C decimals will not be displayed. So make sure to differ between for example -2.7 (minus two point seven) and -27 (minus twentyseven). Digital input DI The digital input must refer to DI+ on terminal 41. The digital input may only be wired to voltage-free contacts. Any external voltage applied to a digital input may seriously damage the unit. Universal input UI The universal input can, depending on the choice of application, be made to act as either an analogue input or as a digital input. When used as an analogue input it is for 0...10 V DC input signals. When the Universal input is used as an analogue input it must refer to the AGND terminal or directly to G0. When used as a digital input it must refer to UI+ on terminal 43. It may then only be wired to voltage-free contacts. Analogue outputs Analogue outputs must refer to a AGND terminal or directly to G0. If the Optigo OP5 and active sensors and actuators connected to it share transformer, it is essential that the same transformer-pole is used as reference for all the equipment. Failure to do so will prevent the equipment from functioning as intended and may also lead to damages.

Optigo can be configured to any one of the following control modes. 1. Temperature control. The temperature at the sensor is kept at the setpoint value by controlling the output signals on AO1 and AO2. A single PI control loop is used. 2. CO2 control. The CO2-value at the sensor is kept at the setpoint value by controlling the output signal on AO1. A single PI control loop is used. 3. Humidity control. The humidity at the sensor is kept at the setpoint value by controlling the output signals on AO1 and AO2. AO1 is used for humidification, AO2 for dehumidification. A single PI control loop is used. 4. Pressure control. The pressure at the sensor is kept at the setpoint value by controlling the output signal on AO1. A single PI control loop is used. 5. Pressure control with outdoor compensation. The pressure at the sensor is kept at the setpoint value by controlling the output signal on AO1. The setpoint is automatically adjusted according to the outdoor temperature. A single PI control loop is used. Control mode 1, Temperature control The analogue outputs can be configured to the following combinations: AO1 / AO2 1. Heating / - 2. Cooling / - 3. Heating / Cooling

DI1, Start signal Normal control will only be activated when this input is activated, closed. When the start signal is deactivated the controller will set the outputs to 0. Note: This input must always be wired since it controls the starting and stopping of normal control. Universal input UI1, Change-over The change-over function will make a seasonal change of the function of the output signal on AO1. In summer the output will work as a cooling output and in winter as a heating output. This is used in applications (fan-coil units) where the same piping is used to transport hot water in the winter and chilled water in the summer. The universal input UI1 is used for the change-over function in alternative 8. Wire the input as a digital input using either a manual switch or a thermostat monitoring the supply water temperature to open/close the input. Open contact will give heating control and closed contact cooling control. Damper In applications with dampers it is often desirable to be able to set a minimum amount of fresh air. In the output alternatives 6 and 7 it is possible to set a minimum limit value to the damper output signal. The damper output will then not go lower than the set value during normal operation. On shut-down however the signal will go to zero. In the output mode heating – damper the damper will be fully open for temperatures higher than the setpoint. On increasing heat demand the damper will first close to the minimum value before the heating output starts to increase. In the output mode cooling – damper the damper will be fully open for temperatures lower than the setpoint. On increasing cooling demand the damper will first close to the minimum value before the cooling output starts to increase. 24 V AC Start signal + - G G0 DI+ DI1 UI+ UI1 AGND AI1 1 2 3 41 42 43 44 50 51 20 21 22 AGND AO1 AO2 °C G0 G Y G0 G Y

DP / CO2 CO2 The output signal will increase when the CO2-value rises above the setpoint value. The CO2-sensor must have a 0...10 V DC output for example: CO2RT, CO2RT-D Room sensors CO2DT Duct sensor The transmitter range cannot exceed 5000 ppm at 10 V DC output. DI1, Start signal Normal control will only be activated when this input is activated, closed. When the start signal is deactivated the controller will set the output to 0.

RH RH max Humidification and dehumidification can be used simultaneously. A neutral zone can be set between humidification and dehumidification. The humidity transmitter must have an output signal of 0...10 V DC, for example: HRT, HRT250 or HRT350 Room humidity transmitters HDT2200 or HDT3200 Duct transmitters DI1, Start signal Normal control will only be activated when this input is activated, closed. When the start signal is deactivated the controller will set the outputs to 0. Maximum Limiting, RH Max When running humidification with the main sensor in the room it is sometimes desirable to have some sort of maximum limiting on the humidity in the supply duct. To create such a limiting function, place an on/off humidistat such as HMH in the supply air duct and wire it into the start signal circuit on DI1. The humidistat should be normally closed. Opening of the contact when the humidity rises above the set maximum value will force the humidity output to 0. 24 V AC Start signal Humidity transmitter Humidifier Dehumidifier HMH Max limiting humidistat G G0 DI+ DI1 UI+ UI1 AGND AI1 1 2 3 41 42 43 44 50 51 20 21 22 AGND AO1 AO2 - + - + % RH G0 G Y

All setting and configuration is done using the display and encoder. The menu information on the display is organised in a tree fashion. Using the encoder you can move between menus, set values etc. In any of the configuration menus, a press on the encoder will activate change mode. You can then rotate the encoder button to move between choices or set values. A second pressing of the button will accept the choice. The menu system is divided into two levels: The Basic level and the 10-second level which contains all the configuration menus. The Basic level The Basic level comprises three sets of menu displays, the Base Display, the I/O Displays and the Setpoint Display. Base Display This is an example of the Base Display, the display that is normally shown when there is no operator activity. The upper line shows which control mode has been configured, in this case control mode 1, Temperature control. The bottom line shows the actual value of the main input parameter. There are bar-graphs showing the current output levels. In control mode 1 there are symbols showing how the outputs have been configured (Heating, Cooling, Damper or Change-over). I/O When the Base Display is shown, by twisting the knob counter clockwise until the text I/O is displayed and then klicking on it, you can gain access to a menu where you can look at the values and states of all inputs and outputs. To exit this menu again, klick on the knob and then twist the knob clockwise and you will be returned to the Base display. Setpoint When in the Base Display, a press on the encoder button gives direct access to the Setpoint menu. See chapter 7 Setpoint.

This level is reached from the Base Display by depressing and holding the encoder button for 10 seconds. The 10-second level holds all the configuration menus. See chapter 8 Configuration. Note: The controller must displat the Base Display when pressing the encoder knob to reach the 10-second level. Display symbols Configuration level Menu number Bargraph AO1 output level Bargraph AO2 output level AO2 Graphic output signal Control mode 1 only AO1 Graphic output signal Control mode 1 only Active 0...10V input signal Temperature control Outdoor compensation configured Menu holds changable values

The setpoint menu is normally accessed from the Base Display by a klicking on the encoder knob. If you wish to change the displayed value, klick on the knob again and the change indicators will start to flash to show that you are now in change mode. Twist the knob, clockwise to increase the value, counter-clockwise to decrease. In applications with active input signals (control modes 2, 3, 4 and 5) the setpoint cannot be set higher than the value corresponding to 10 V DC input signal. When the desired value is shown, klick on the knob to acknowledge. To return to the Base display, twist the knob. For configurations involving a single output signal the setpoint is the starting point for the output signal. For configurations involving two diverging output signals with neutral zone (heating – cooling or humidification – dehumidification) the setpoint is placed in the middle of the neutral zone. For configurations involving two outputs without neutral zone (heating – heating, cooling – cooling, heating – damper or cooling – damper) the setpoint value is the starting point for the first sequence (Y2)

All the configuration menus lie in the 10-seconds level. This level is accessed from the Base Display by pressing and holding the encoder button for 10 seconds. There are numerous configuration menus covering all available options and combinations. In some cases, making a certain choice in one menu will mean that you will only see certain other menus. For example, the menu for setting the damper minimum limit is only shown if you have configured AO2 to be a damper control output. Menus 1.0 – 5.0 In the first set of configuration menus you choose which of the five control modes you wish to run. The upper text row, the lower text row number and the first digit in the menu-number show which control mode is at hand. 1. Temperature control 2. CO2-control 3. Humidity control 4. Pressure control 5. Pressure control with outdoor compensation Menu X.1 Output signals (Control mode 1 only), Transmitter range (Control modes 2, 3, 4 and 5) Control mode 1. For temperature control there is a choice of 8 different output signal combinations. Select one fitting the application on hand. Output Graphic AO1 / AO2 symbol symbol 1. Heating / - \ 2. Cooling / - / 3. Heating / Cooling \ / 4. Heating / Heating \ \ 5. Cooling / Cooling / / 6. Heating / Damper \ / 7. Cooling / Damper \ / 8. Change-over / -

of the output signals and also a symbol next to the bar-graph for each output. Example, Menu 1.1 Temperature control with output alternative 3 Heating/Cooling Control modes 2, 3 4 and 5 For control modes using active 0…10 V DC transmitters you need to scale the input signal. For example, if you have a pressure transmitter that will give a 0…10 V output for a pressure range of 0 to 5000 Pa, set the value to 5000 Pa. Note that for pressure transmitters the pressure, depending on the range, may be given in Pa or kPa. Ranges up to 500 kPa can be set. Also, not all values between 0 and 500 kPa kan be set since this would involve a great amount of twisting on the encoder. In the low ranges the values are close but become increasingly further between as the values go up. For CO2 transmitters the range is set in ppm and for humidity control in % RH. Example, Menu 2.1 CO2-control with input signal 0…10 V for CO2 value 0…2000 ppm. Menus X.2 Neutral zone (Control mode 1 and 3) In two control modes involving diverging output signals (heating – cooling or humidification – dehumidification) you can set a neutral zone between the outputs. The setpoint will be placed at the middle of the neutral zone. Menus X.3 P-band Here you set the P-band (Proportional band) The P-band unit depends on the choice of control mode. The P-band is the control offset necessary to drive an output signal from 0 to 100%. In configurations involving two outputs the same P-band applies to both outputs. Control mode 1 menu 1 Output alternative 3, Heating/Cooling AO1 Heating AO2 Cooling Output signals, graphical

Here you set the Integration time (Reset time). If the I-time is set to 0 the integration function is disabled and the controller will act as a P-controller. Menu 1.5 Damper minimum position (Control mode 1 only) If you in menu 1.1 have configured output AO2 to be a damper, alternative 6 or 7, you can set a minimum value to the damper signal. . The damper output will then not go lower than the set value during normal operation. On shut-down however the signal will go to zero and fully close the damper. Menu 5.7 Start point for outdoor compensation (Control mode 5 only) S.P is the outdoor temperature at which the setpoint compensation starts. At temperatures higher than S.P the normal setpoint value is maintained. When the outdoor temperature falls below S.P the pressure setpoint will change linearly on decreasing temperature to reach the pressure set by SPL in menu 5.8 below at an outdoor temperature of -20°C Menu 5.8 Maximum compensation (Control mode 5 only) SPL is the setpoint to be held at an outdoor temperature of -20°C. The setpoint shift starts when the outdoor temperature falls below the value set in S.P in menu 5.7 above and will change linearly with decreasing outdoor temperature reaching SPL when the outdoor temperature is -20°C. Note that SPL is not a setpoint shift value to be added to the normal setpoint value but the actual setpoint value at -20°C outdoor temperature. S.P 10°C -20°C 300 SPL 200 Outdoor temp Setpoint Example: With an ordinary setpoint of 300 Pa, a starting point S.P of +10°C and a SPL of 200 Pa at -20°C you get the following setpoint-to-outdoor temperature relation

After the last configuration menu there is a menu where you can look at the actual values of all the inputs and outputs. This menu can also be accessed directly from the Base Display by twisting the encoder knob counter clockwise and then pressing. See chapter 6. Menu OK Last of the configuration level menus is the OK-menu. To leave the configuration level, go to this menu and press the encoder knob. On exit from the configuration level you will be returned to the Basic level. There is also a time-out function that will automatically exit the configuration level after 5 minutes of inaction. Storage of settings All configuration settings become valid as soon as they are entered by klicking the encoder knob. They are however not written to the flash memory until you exit the configuration level either via the OK menu or via the time-out function. To exit the configuration level without saving the changes to flash memory, cut the supply voltage when still in the configuration level. All values will be kept as they were before you entered the configuration level. Reset to factory setting The OP5 can be reset to factory settings by configuring Humidity control (mode 3) and setting the P-band to 99. Then cut the power supply. When power is reapplied all configuration settings will be reset to factory setting.
