with a D-BEDIX, the key-operated selector switch has top priority. In this condition any
change of the operating mode made through the D-BEDIX is memorized and will be
implemented upon revocation (release) or removal of the key-operated selector switch.
For switching over to the operating mode NIGHT (by means of the key-operated selec-
