Terminal Designation Operation
10 G Supply voltage 24 V AC
11 G0 Supply voltage 0 V
12-14 No function.
20 GDO 24 V AC out common for DO. Internally connected to terminal 10, G.
21 G0 0 V common for UO. Internally connected to terminal 11, G0.
22 UO3
Output for VAV or EC-fan.
For forced ventilation. 24 V AC output, max. 2.0 A. 24 V actuator is connected between
terminal 22 and terminal 20, GDO.
Alternatively For 0...10 V DC damper control/EC-fan. The damper actuator/EC-fan 0...10 V
control signal terminal is connected to terminal 22 and its supply terminals to terminals 10
and 11. Make sure that the reference pole G0 is connected to the correct terminal on the
actuator.
23 UO1
Control output heating (FS), cooling or heating or cooling via change-over.
For a 0...10 V DC valve actuator, max 5 mA (FS). The valve actuator’s 0...10 V control signal
terminal is connected to terminal 23 and its supply terminals to terminals 10 and 11. Make
sure that the reference pole G0 is connected to the correct terminal on the actuator.
alternatively For a 24 V AC thermal actuator, max 2.0 A. The thermal actuator is connected
between terminals 23 and 20, GDO.
alternatively For a 24V AC actuator with spring return, max. 2.0 A. The actuator is connected
between terminals 23 and 20. This can be congured either through the display or through
Regio tool©. The output signal for UO1 can be set to NC (normally closed) or NO (normally
open).
24 UO2
Control output heating or cooling (FS).
For a 0...10 V DC valve actuator, max 5 mA (FS). The valve actuator’s 0...10 V control signal
terminal is connected to terminal 24 and its supply terminals to terminals 10 and 11. Make
sure that the reference pole G0 is connected to the correct terminal on the actuator.
alternatively For a 24 V AC thermal actuator, max 2.0 A. The thermal actuator is connected
between terminals 24 and 20, GDO.
alternatively For a 24V AC actuator with spring return, max. 2.0 A. The actuator is connected
between terminals 24 and 20. This can be congured either through the display or through
Regio tool©.
30 AI1
For an external room sensor, PT1000. Measuring range 0...50°C. The sensor is connected
between terminals 30 and 41, AGnd.
31 AI2
For a 0...10 V CO2 sensor
alternatively Flow input
alternatively 0...10 V input
32 DI1
Occupancy detector. A potential-free contact is connected between terminals 32 and 40, +C.
Closed contact corresponds to occupancy.
alternatively Window contact (DI). A potential-free contact is connected between terminals 33
and 40, +C. Closed contact indicates closed window.
alternatively Change-over.
33 DI2/CI
Regin’s condensation detector, KG-A/1 (FS). The sensor is connected between terminals 33
and 41, AGnd.
alternatively Window contact (DI). A potential-free contact is connected between terminals 33
and 40, +C. Closed contact indicates closed window. alternatively Change-over.
40 +C 24 V DC out common for DI and UI (with digital function)
41 AGnd Analogue ground, reference for AI and UI (with analogue function)
42 A RS485-communication A
43 B RS485-communication B
