If room humidity exceeds a switching point r.h., the control value r.h.
for the respective stage is switched on.
Control value r.h. is switched off again when room humidity
< switching point r.h. – hysteresis.

If room humidity exceeds switching point r.h., the control value
parameterized for this stage is issued.
The control value again issues the next lower stage value when room
humidity < switching point r.h. – hysteresis.
