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
A
GND
All A GND terminals are interconnected and also connected to G0.
Analogue inputs AI
The analogue inputs must refer to an A GND terminal or directly to G0. The analogue inputs
are for PT1000 temperature sensors only. AI1 has a range of 0…+84°C. AI2 has a range of
-20…+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
When the Universal input is used as an analogue input it must refer to the A GND 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 A GND 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 and DO2 are triac controlled. They must refer to G DO on
terminal 13.

11
15
14
13 G DO
The outputs will deliver 24 V AC, 0.5 A continuous.
The outputs cannot be used to drive DC relays.
The digital output DO3 is a change-over relay. 230 V, 5 A.

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 / Exhaust 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. Water radiator heating system 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.

13
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 / Exhaust air temperature control” you also
need 2 sensors, “Supply air sensor” on AI1 and either “Room sensor” or “Exhaust 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
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.

14
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 shut-down or activation of the high
temperature limit) the heating output will be shut down immediately but the fan will run on
for a further 3 minutes to cool the heater.
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 has been 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 0 at outdoor temperature S.P. and increases to reach the value CMP at -20°C
outdoor temperature. Example: Normal setpoint = 20, S.P.=10 and CMP = 5 will give the
following result:
S.P.
10°C-20°C
20°C
25°C

Setpoint +CMP
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.
Fan indication
Unless this input is activated 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 activated in spite of the fan control output being off.
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
Water radiator heating system with outdoor curve.

GT1
GT2
For this control mode you need two sensors, “Supply temperature” on AI1 and “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.
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 SP L and SP H where
SPL is the supply temperature to be held when the outdoor temperature is +20°C and SPH is
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.

Room sensor
An optional room sensor can be connected to UI1. 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.
To indicate that room control is activated the symbol showing a thermometer outside the
house is replaced by a thermometer inside the house
Pump control
The pump control output is activated whenever as the temperature control output signal is
greater than zero. It has a 10 minute stop delay.

18
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.

Chapter 6 Display and encoder
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 klick on the encoder will activate change mode. You
can then rotate the encoder button to move between choices or set values. A second klick 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.
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 input 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.
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.
