Optigo controllers
Optigo is a range of pre-programmed, configurable controllers that can be set to handle everything from temperature control or humidity control to CO2 control or pressure control. The Optigo series comprises two different types, OP5 and OP10. OP5 has 5 inputs/outputs and can be configured to control Temperature, CO2, Humidity or Pressure. From revision 18, there is a new analogue input for connection of an external PT1000 setpoint device for control mode 1 (Temperature control). OP10 has 10 inputs/outputs and can be configured to control Temperature (ventilation control with heating and cooling), Water-heated radiator heating with outdoor temperature dependent control-curve or Domestic hot-water control. From revision 20, there is a new analogue input for connection of an external PT1000 setpoint device for control modes 1-4. OP10 is available in two versions, OP10 with 24 V AC supply voltage and OP10-230 with 230 V AC supply voltage. Mounting Optigo is designed primarily for DIN-rail mounting but can also be screw-mounted to any suitable surface.

Chapter 4 Installation and wiring

Installation

Optigo is intended to be installed and handled by professional personnel. The installation should conform to the requirements of installation category 3 and pollution degree 2. There are a number of mounting alternatives: DIN-standard casing (minimum 7 modules) Cabinet, either on a DIN-rail or, using the two screw-pockets provided, by being screwed to any suitable flat surface in the cabinet The controller can also be mounted in a cabinet door or other control panel, using a suitable front-mounting kit Observe that there is a risk of electric shock on contact with terminals 1-3 and 10-12. Mount Optigo in a DIN-casing or similar where it can be used without risk of electric shock. The casing should provide at least 6 mm insulation from connected cables and terminals 1-3 and 10-12. Optigo should be protected against overload by a fuse in the installation. Since the maximum load is 1000 VA, a fuse of 6 A is suitable. Circuit breaker and fuse: The controller should be connected to a circuit breaker so the power supply to the controller can be cut. Place this breaker close to the controller where it is easy for the operator to reach. It should be clearly marked as a circuit breaker for the controller.
For installations which are connected to 230 V AC: -

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.

Supply voltage

OP10-230: 230 V AC +10%, -15%, 50/60 Hz. 6 VA OP10: 24 V AC 15%, 50/60 Hz. 6 VA If the Optigo OP10 (24V supply model only) 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.

Inputs and outputs

All AGND terminals are interconnected and also connected to G0.

Analogue inputs AI

The analogue inputs must refer to an AGND terminal. AI1 and AI2 are for PT1000 temperature sensors only. AI1 has a temperature range of 084C. AI2 has a temperature range of -30+54C. SPI is only intended for a PT1000 setpoint device, the range is 0.40C.

Digital inputs DI

The digital inputs must refer to DI+ on terminal 41. The digital inputs may only be wired to voltage-free contacts. Any external voltage applied to a digital input may harm 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 PT1000 temperature sensors. The input then has a range of 0+84C UI must refer to UI+ on terminal 43.

Analogue outputs

Analogue outputs must refer to a AGND terminal or directly to G0. If the Optigo OP10 (24V supply model only) 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.

Digital outputs

The two digital outputs DO1 (terminal 14) and DO2 (terminal 15) are triac controlled. The triacs are internally connected to G0. Each triac can handle 24 V AC, 500 mA. The outputs cannot be used to drive DC relays. When DO1 and DO2 are used for 3-point control DO1 will always be increase signal (open valve) and DO2 always decrease signal (close valve) The outputs should normally refer to GDO on terminal 13. GDO is internally connected to G and supplies 24 V AC. In OP10 GDO can deliver the necessary 2 x 500 mA.

13 GDO G0 G0

In OP10-230 however, the internal transformers capacity restricts the current on GDO to approx. 165 mA. For more power an external transformer must be used. Wire the transformer according to the following figure. The two 500 mA fuses are important to prevent possible overloading of the triacs.

230 V AC
Optigo can be configured to any one of the following control modes.
1. Supply air temperature control. The supply air temperature is kept at the setpoint value by controlling the output signals on AO1 and AO2. A single PI control loop is used.
2. Supply air temperature control with outdoor compensation. The supply air temperature is kept at the setpoint value by controlling the output signals on AO1 and AO2. A single PI control loop is used. The setpoint is automatically adjusted according to the outdoor temperature.
3. Cascade connected, room temperature influenced, supply air control. The room temperature is controlled by means of adjustments in the supply air temperature, depending on the room temperature. A cascade controller with a room temperature and supply air temperature sensor is used. The supply air temperature is minimum and maximum limited.
4. Radiator circuit control with outdoor curve. The water temperature setpoint is changed according to the outdoor temperature. A single PI control loop is used. A room temperature sensor can be added to give corrective action if the room temperature differs from the setpoint
5. Domestic hot water control. The water temperature is kept constant by controlling the output signal on AO1. A single PID control loop is used.

Control modes 1, 2 and 3

These three modes have a lot in common and will therefore be treated in a single section. For control mode 1, Supply air temperature control you need only one sensor,Supply air sensor on AI1.
For control mode 2, Supply air temperature control with outdoor compensation you need two sensors, Supply air sensor on AI1 and Outdoor sensor on AI2.
For control mode 3, Cascade connected room / extract air temperature control you also need 2 sensors, Supply air sensor on AI1 and Room sensor, which are placed in the room or in the extract air on AI2. The cascade controller has inputs for supply air sensors and room sensors. The room temperature setpoint is set and the controller will adjust the supply air setpoint until reaching the desired room temperature. The supply air setpoint is minimum and maximum limited. The P-band and I-time values for the supply air control are chosen so that a stable control is achieved. The P-band for the room temperature influence is set on PCd. The I-time for the room temperature influence is a fixed value of 600 seconds. Definition of P-band the room temperature influence (PCd): The change in room temperature which results in a change in the supply air setpoint, corresponding to the difference in temperature between the set maximum and the minimum limits.

The analogue outputs can be configured to the following combinations:
1. Heating 2. Cooling 3. Heating 4. Heating 5. Cooling 6. Heating 7. Cooling
/ Cooling / Heating / Cooling / Dampers / Dampers
In alternative 4, Heating-Heating AO2 will be activated first on increasing heat demand. In alternative 5, Cooling-Cooling AO2 will be activated first on increasing cooling cemand. In alternative 6, Heating-Damper, at temperatures above the setpoint the damper on AO2 will be fully open. On increasing heating demand, the damper on AO2 will first close to the set minimum value before the heating output on AO1 starts to increase. In alternative 7, Cooling-Damper, at temperatures below the setpoint the damper on AO2 will be fully open. On increasing cooling demand, the damper on AO2 will first close to the set minimum value before the cooling output on AO1 starts to increase.

3-position control

Instead of an analogue output you can configure a single 3-position (increase / decrease) output. You will then only have the following output choices: Heating Cooling DO1 is used for increase signal and DO2 for decrease. This option cannot be combined with alarm output. A single P control loop is used. OP10-230 generates 24 V AC itself for control of 3-position actuators. 230 V actuators cannot be used without relays.

External setpoint

From revision 20, it is possible to use an external PT1000 setpoint device, e.g. TG-R4/PT1000 or TBI-PT1000. The setpoint device is connected between terminal 54 SPI and the reference for the analogue inputs, AGND. For more information on configuration and setpoint reading, see chapters 7 and 10.

Universal input UI1

Electric heating If the Optigo is used to control electric heating UI1 is used for the high temperature limit switch. Connect and configure as a digital input. The input is normally closed. Whenever the running mode switches to Off, (normal shutdown) the heating output will be shut down immediately but the fan will run on for a further 3 minutes to cool the heater. On activation of the high temperature limit, the heating output will be shut down immediately and there will be no cool-down period.

Wiring suggestion for high temp limit when using electric heating. Drawn with high temp limit activated.
N.B. It is important that the high temperature thermostat is hardwired to disconnect the power to the heater to ensure that the heating is shut down when the thermostat is activated even if the Optigo should be faulty.
Water heating When controlling a water heater, UI1 can, when necessary, be used for a frost protection sensor. Connect and configure as an analogue input. The frost protection function can be tied to either of the analogue outputs. The heater return water temperature is monitored by the frost protection sensor. Should the temperature at the frost protection sensor fall below 12C an internal, proportional signal is generated that is used to force the heating valve open to try and prevent freeze-up of the heater. Optigo OP10 user manual Chapter 5 Control modes 16
Internal signal Prop.band 100 %

0% 7C 12C

The frost protection signal (Internal signal) will increase linearly to 100 % at 7C at which point the frost protection alarm is triggered. The fan will then be shut down and the controller will go into shutdown mode.
Shutdown mode (Only if frost protection sensor has been configured) Whenever the running mode switches to Off, (normal shut-down or frost protection is activated) the controller will go into Shutdown mode. The shutdown controller will control the output that is tied to the frost protection function to maintain a constant 25C at the frost protection sensor.

Outdoor compensation

In control mode 2, Supply air control with outdoor temperature compensation, the supply air temperature setpoint can be displaced according to outdoor temperature. The displacement starts from outdoor temperature S.P and reaches the setpoint value + the compensation (CMP) at -20C outdoor temperature. For example: Normal setpoint = 20, S.P=10 and CMP = 5 will give the following result:

Setpoint

Setpoint + CM 25C P Setpoint 20C -20C 10C S. P Outdoor temp

Damper

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.

DI1, Fan indication

Unless the fan indication input is active (closed) indicating that the fan is running, the controller will not start normal temperature control and an alarm will be generated. An alarm will also be generated if the input is active (closed) when the fan control output is off.

DI2, Extended running

Activation of this input will force the controller to running mode even if internal scheduler is in Off-mode. The unit will run as long as the input is activated.

Wiring examples

See also chapter 4 Installation and wiring.
A. OP10 with electric heating (for example via PULSER-X/D or TTC25X) and damper. Cascade control.
B. OP10-230 with water heating, 3-position output. Supply air temperature control with outdoor compensation and external setpoint device. OP10-230 generates 24V AC itself for control of 3-position actuators. 230 V actuators cannot be used without relays.
Control mode 4, Radiator circuit control with outdoor curve
For this control mode you need two sensors, GT1 Supply temperature on AI1 and GT2 Outdoor sensor on AI2. You can also have a room temperature sensor on UI1 to let the room temperature offset give correction to the supply temperature. Wire UI1 as an analogue input. When using a room sensor, it is possible to set the room setpoint via an external PT1000 setpoint device (this applies to controllers with revision R20 or later).
Instead of the analogue output you can configure a 3-position (increase / decrease) output using DO1 and DO2. DO1 is used for increase signal and DO2 for decrease. This option cannot be combined with alarm output. A single P control loop is used. OP10-230 generates 24V AC itself for control of 3-position actuators. 230 V actuators cannot be used without relays.

Control curve

The supply temperature setpoint is determined by a outdoor temperature/supply temperature curve. The basic control curve is a straight line between the two setpoints SPL and SPH where SPL is the supply temperature to be held when the outdoor temperature is +20C and SPH is the temperature to be held at an outdoor temperature of -20C. An extra temperature boost can be added at 0C outdoor temperature. The boost receeds from the set value to 0 over 3 degrees. In the Setpoint menu a parallel displacement of the whole curve can be added.

OP10 with 0.10V actuator

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 click on the encoder will activate change mode. You can then rotate the encoder button to move between choices or set values. A second click of the button will accept the choice. The menu system is divided into three levels: The Basic level, the 3-second level which contains the clock and scheduler settings and the 10-second level which contains all the configuration menus.

The Basic level

The Basic level comprises four sets of menu displays, the Base Display, the I/O Displays, the alarm handling display 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. It shows the current time and the actual value of the main parameter. There are bar-graphs showing the current output levels together with symbols showing how the outputs have been configured (Heating, Cooling or damper etc). Also a symbol showing which of the five control modes is configured and an alarm symbol that is displayed in the event of an alarm condition. The fan symbol (control modes 1, 2 and 3 only) is lit as long as the fan indication input is activated.
When the Base Display is shown, by twisting the knob counter clockwise until the text I/O is displayed and then clicking 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, click on the knob and then twist the knob clockwise and you will be returned to the Base display.
When in the Base Display, a click on the encoder button gives direct access to the Setpoint menu. See chapter 7 Setpoint.
If there are any active alarms, clicking on the encoder button will instead give access to the alarm handling menus. Here the alarms are displayed and can be acknowledged. There is one menu display for each alarm with symbols showing which type of alarm it is. See chapter 8 Alarm handling.

Calculated setpoint

For control modes with outdoor temperature compensation or cascade control, the controller does not work towards a fixed setpoint value. Instead, it works towards a calculated setpoint, which varies with the outdoor temperature or, when using cascade control, the room temperature. The calculated setpoint is displayed by turning the knob clockwise when in the Base Display.

Scheduler, general

The scheduler function is only available for control modes 1, 2, 3 and 4. The easiest way to understand the scheduler function is to compare it to the type of mechanical timer that has a rotating disk where you can pull out knobs that on passing the switch kan turn it ON or OFF. There are 4 ON-points and 4 OFF-points. Each point has its own menupage where 0.1, 0.3, 0.5 and 0.7 are ON-points and 0.2, 0.4, 0.6 and 0.8 are OFFpoints. Control modes 1, 2 and 3 have the same type of scheduler where the ON-points will start the unit and the OFF-points will shut it down. Control mode 4 uses the scheduler for switching to economy mode (ECO) where the temperature is lowered by a settable number of degrees. Here the ON-points will switch ECOnomy period on and the OFF-points will switch back to comfort temperature.
Scheduler, control modes 1, 2 and 3 Menus 0.1 0.8
With the 4 pairs of on-off menus you can create 4 different running periods, either for single days or for a group of days. The day of the week number can be set to any value 1 to 9 or -- for unused menus. Numbers 1 to 7 represent the days of the week Monday to Sunday. Number 8 will apply the set time every day Monday through Friday and number 9 will apply the set time all 7 days of the week. Optigo OP10 user manual Chapter 9 Clock and scheduler 27
For example, you wish the unit to run Monday to Friday between 07:30 and 18:00, Saturday 8:00 to 14:00. Set first on-time to day 8 and 7:30, the first off-time to day 8 and 18:00. Set the second ontime to day 6 and 8:00 and the second off-time to day 6 and 14:00. Set all others to day --.
If you want the unit to run around the clock, set the on-time to 0:00 and the off-time to 0:00.

Menu 0.9, Override

After the eight switching point menus there is a ninth, 0.9. There the present output status of the scheduler is shown and you can manually override the setting. If, for example, the switch is shown as ON and you change it to OFF it will remain off either until you manually change it to On again or until the next timer ON-point is reached.

Menu OK

After the scheduler menus there is a final menu, OK. A klick on the encoder knob will exit the Clock and Scheduler level and return you to the Basic Display.
Scheduler, control mode 4 Menus 0.1 0.8
With the 4 pairs of on-off menus you can create 4 different economy periods, either for single days or for a group of days. The day of the week number can be set to any value 1 to 9 or -- for unused menus. Numbers 1 to 7 represent the days of the week Monday to Sunday. Number 8 will apply the set time every day Monday through Friday and number 9 will apply the set time all 7 days of the week. In this application you need to remember that ON will switch ECOnomy period (lowered temperature) on and OFF will switch ECOnomy period off. For example, every weekday morning you want the temperature to start rising at 06:00 and to remain at comfort level until 21:00. On Saturday and Sunday you want high temperature from 07:00 to 23:30. Set first on-time to day 8 and 21:00, the first off-time to day 8 and 06:00. Set the second ontime to day 6 and 23:30 and the second off-time to day 6 and 07:00. Set the third on-time to day 7 and 23:30 and the third off-time to day 7 and 07:00.

0C temperature boost

In control mode 4 an extra temperature boost can be added at 0C outdoor temperature. The boost recedes from the set value to 0 over 3 degrees.

D-factor

Control mode 5, Domestic hot water temperature control is often a very difficult application which calls for responsive control. Optigo therefore utilises PID-control for this control mode. In this menu you set the D-factor (the derivative factor).
Menus X.7 Universal input UI1 (Control modes 1, 2, 3) Pump exercise (Control mode 4) Periodic overheating (Control mode 5)

Input UI1

For control modes 1, 2 and 3 you can choose to configure the universal input UI1 as either an analogue input for a frost protection sensor on either output (snowflake-symbol) in a waterheated system or as a digital input for a high temperature limiting switch (sun-symbol) in an electric heater. It can also be set to --, not active. If set to frost protection sensor Optigo will activate the frost protection function and also shutdown mode, see chapter 5. If set to high temperature limit switch, the fan will run for an extra 3 minutes after the heating output has been turned off at shutdown.

Pump exercise

If the pump stands still for prolonged periods during the summer there is the risk of the pump impeller seizing. To reduce this risk the Optigo has a pump exercise function which will start and run the pump for 5 minutes at 15:00 each day. In this menu the exercise function can be turned Off if not desired. Default is On.
To reduce the risk of Legionella bacteria growth a periodic overheating of the water can be configured. The water temperature will be raised to 65C once daily at 03:00 (3 am). The elevated temperature is maintained for 10 minutes. In this menu the overheating function can be turned Off if not desired. Default is On.
Menus X.8 Startpoint for outdoor compensation, S.P (Control mode 2) Supply air min limit (Control mode 3) Low temperature setpoint (Control mode 4)
For control mode 2. S.P is the outdoor temperature at which the setpoint compensation starts. At temperatures lower than S.P a compensation will be added to the setpoint value. The maximum compensation is set in menu 2.9 and is achieved at -20C

For control mode 3 the supply air temperature can be minimum and maximum limited. In this menu you set the minimum supply air temperature.
For control mode 4 you need to establish a relationship between outdoor temperature and supply water temperature. This is set by the two setpoints SPL and SPH where SPL is the water temperature to be held at an outdoor temperature of +20C and SPH is the water temperature to be held at -20C. Intermediate values are calculated with linear interpolation. In this menu you set SPL.
Menus X.9 Maximum compensation, CMP (Control mode 2) Supply air max limit (Control mode 3) High temperature setpoint (Control mode 4)
For control mode 2. The maximum setpoint compensation value. Compensation will start to be added to the setpoint value when the outdoor temperature falls below the start point S.P entered in menu 2.8. The compensation will increase linearily up to the maximum value CMP which is reached when the outdoor temperature has fallen to -20C
For control mode 3 the supply air temperature can be minimum and maximum limited. In this menu you set the maximum supply air temperature.
For control mode 4 you need to establish a relationship between outdoor temperature and supply water temperature. This is set by the two setpoints SPL and SPH where SPL is the water temperature to be held at an outdoor temperature of +20C and SPH is the water temperature to be held at -20C. Intermediate values are calculated with linear interpolation. In this menu you set SPH.

Menu X.E

In this meny, you set whether you want to use an external setpoint device or set the setpoint via the display. External setpoint can be used for control modes 1-3 and control mode 4 when using a room sensor. This menu is only available for controllers with revision number R20 or later.

Menu I/O

After the last configuration menus there is a menu where you can look at the actual values of all the inputs and outputs.
Last of the configuration level menus is the OK-menu. To leave the configuration level, go to this menu and klick on the encoder knob.
On exit from the configuration level you will not be returned to the Basic level but to the Time and Scheduler 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 clicking 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 OP10 can be reset to factory settings by configuring Domestic hot water control (mode 5) and setting the D-factor to 99. Go to the Basic Display. Then cut the power supply. When power is reapplied all configuration and scheduler settings will be reset to factory setting.
