Provides the room humidity value from the integrated sensor.
Units with display: Must be placed in a group address to display operation/symbol on the display.
External room humidity sensor values, see object 70
External outside humidity sensor values, see object 69
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 assume
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 positioning 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 positioning signal once again outputs the value of the next smaller
stage, for room humidity < switching r.h. - Hysteresis.
