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.
alternatively
Lighting control On/Off.
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 configured either
through the display or through Regio tool
