Provides the room hum idity value from the integrated sens or.
Units with display: Must be placed in a group addres s to display operation/symbol on the display.

The configured default switching points apply as long as no value is received from the bus.
In manual mode (obj. 30, 1=Manual), a setpoint is received via this object and outputted directly as modulating positioning
signal (object 36).
Changing over to the manual mode permits receipt of a manual setpoint (Obj. 29) for the modulating positioning signal
(Obj. 36). Otherwise, the configured positioning signals for the applicable stage are outputted.
All controller outputs are switched off upon receipt of "Controller off".
The controller remains disabled until "Controller on" is received. The default value is controller on = 1.
For controller override, the stage defined in the parameter "Stage is overridden" is enabled. Objects 33, 34, 35 as sume
only the value "1=On" for the corresponding object; the other two objects the value "0 = Off". The modulating positioning
signal (obj. 36) outputs the value configured for the applicable stage.
Override has the highest priority. The default state is "Normal".
The stage belonging to positioning signal r.h. is switched on if room humidity overrides a
switching point r.h. The pos itioning signal r.h. is switched off again for room humidity <
switching r.h. - hysteresis.
The positioning signal configured for the stage is outputted if room humidity overrides a
switching point r.h. The pos itioning signal once again outputs the value of the next smaller
stage, for room humidity < switching r.h. - Hysteresis.
