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.

Inputs and outputs
A
GND
All A GND terminals are interconnected and also connected to G0.
Analogue input AI
The analogue input must refer to an A GND 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 -2 7 (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 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 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.

Chapter 5 Control modes
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. CO 2 control.
The CO 2 -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

11
4. Heating / Heating
5. Cooling / Cooling
6. Heating / Damper
7. Cooling / Damper
8. Change-over/ - (Seasonal change-over between heating and 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.

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.

Control mode 3, Humidity control
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.

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 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.

17
The 10-second level
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.

Chapter 7 Setpoint
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)

19
Chapter 8 Configuration
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.

For each alternative the number representing it is shown along with a graphic symbolisation
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 CO 2 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.
