Optigo OP10 user manual Chapter 4 Installation and wiring 10
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
For installations which are connected to 230 V AC:
-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.

Optigo OP10 user manual Chapter 4 Installation and wiring 11
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
AGND
All AGND terminals are interconnected and also connected to G0.

Optigo OP10 user manual Chapter 4 Installation and wiring 12
Analogue inputs AI
The analogue inputs must refer to an AGND terminal. The analogue inputs are for PT1000
temperature sensors only. AI1 has a range of 0…+84°C. AI2 has a range of
-30…+54°C
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 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 PT1000 temperature sensors. The input then has a
range of 0…+84°C
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.

In OP10-230 however, the internal transformer’s capacity restricts the current on GDO to
approx. 165 mA.

Optigo OP10 user manual Chapter 4 Installation and wiring 13
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.

Optigo OP10 user manual Chapter 5 Control modes 14
Chapter 5 Control modes
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 / extract air temperature control.
An offset in room temperature will adjust the supply air temperature setpoint so as to
eliminate the room temperature offset. One PI and one P control loop are used. The supply
air temperature can be 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.

Optigo OP10 user manual Chapter 5 Control modes 15
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 either “Room sensor” or “Extract sensor” on
AI2.
The analogue outputs can be configured to the following combinations:
AO1 /AO2
1. Heating / -
2. Cooling / -
3. Heating / Cooling
4. Heating / Heating
5. Cooling / Cooling
6. Heating / Damper
7. Cooling / Damper
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.

Optigo OP10 user manual Chapter 5 Control modes 16
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.
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 12°C an internal, proportional signal is
generated that is used to force the heating valve open to try and prevent freeze-up of the
heater.

The frost protection signal (“Internal signal”) will increase linearly to 100 % at 7°C 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 25°C 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 -20°C outdoor temperature. Example: Normal setpoint = 20, S.P=10 and CMP = 5
will give the following result:

Outdoor temp
Setpoint
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.

Control mode 4, Radiator circuit control with outdoor curve
GT1
GT2
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.
3-Position control
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.
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 SPLand SPHwhere
SPLis the supply temperature to be held when the outdoor temperature is +20°C and SPHis
the temperature to be held at an outdoor temperature of -20°C. An extra temperature boost
can be added at 0°C 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.
Supply temp
Outdoor temp
SPH
SPL-20 0 +20
Room sensor
An optional room sensor can be connected to UI1. If a room sensor is used, it must be
connected to the Optigo before control mode 4 is selected. Otherwise, the controller will not
detect the sensor. To activate/deactivate the room sensor it has to be connected/not connected
to the Optigo before control mode 4 is selected. The control program is automatically
adapted when a room sensor is connected. Any room temperature offset will displace the
supply setpoint as to eliminate the offset. The room controller is a P-controller with a fixed
P-band of 3K.
If room sensor is activated the Setpoint menu is used to set the room temperature instead of
adding a parallel displacement.
To indicate that room control is activated the display symbol showing a thermometer outside
the house is replaced by a thermometer inside the house.

Optigo OP10 user manual Chapter 5 Control modes 20
DO3, Pump control
The pump control output is activated when the temperature control output signal is greater
than zero, or the outdoor temperature is below 15°C. It is deactivated when the output signal
is zero and the outdoor temperature is greater than 15°C. There is a 10 minute stop delay.
There is a pump exercise function which will start the pump at 15:00 (3 pm) every day and
let it run for 5 minutes. The function can be deactivated.

Periodic overheating
To reduce the risk of Legionella bacteria growth a periodic overheating of the water can be
configured. The water temperature will be raised to 65°C once daily at 03:00 (3 am). The
elevated temperature is maintained for 10 minutes. The function can be deactivated.
