Valid for both settings:
If one of the buttons is pressed while the display is off, the display is switched on to enable
operation. After the last press of the button, the display switches off again after a fixed time of
approx. 20 seconds. The same behaviour applies to switching on via a presence object. The
display only switches on again permanently after the brightness has been exceeded (when
controlling via brightness) or a value greater than "0 %" (when controlling via percentage
value).
After bus voltage failure and subsequent return, the value last set via object is no longer valid
and a value has to be sent again.
