6.3 Application examples
The examples are described for RDG260KN, but they also apply to RDG200KN.
Control output (P201, P204) and terminals for the valves (Y1, Y2) need to be
adapted accordingly.
6.3.1 Humidity control
In the following examples, P461 is configured based on the connected type of
equipment. See details in Humidity [➙ 57].
2-pipe fan coil application for dehumidification, with temperature setpoint shifting
and dehumidifier contact, DC 0...10 V fan and DC valve:
