Initial commissioning using electronic control unit WHSE

1. Check correct wiring.
2. If everything is attached correctly, connect the supply voltage and carry out the following tests for the respectively
correct temperature regulation.
– Function test
Sensor operating mode 1: Constant supply air temperature control
Sensor operating mode 1: Constant supply air temperature control

protection
1. Set DIP switches (Pos.û) 2, 3 and 5 to Position A and DIP switches 1 and 4 to Position B.
2. Turn the internal setpoint potentiometer (Pos. â) clockwise to the end position.
LED Y1 (Pos. á) should light up and the actuator should open the three-way valve.
3. Turn the internal setpoint potentiometer (Pos. â) counter clockwise to the end position.
LED Y2 (Pos. é) should light up and the actuator should close the three-way valve.

Setpoint
1. Set DIP switches (Pos.û) 3 and 5 to Position A and DIP switches 1, 2 and 4 to Position B.
2. Turn the external setpoint potentiometer (TFR) clockwise to the end position.
LED Y1 (Pos. á) should light up and the actuator should open the three-way valve.
3. Turn the external setpoint potentiometer (TFR) counter clockwise to the end position.
LED Y2 (Pos. é) should light up and the actuator should close the three-way valve.
