If the time switch shall operate as a slave of a master time switch, the geographical
zone of the master time switch must be set here.
If that is the case, no more time switch data about the geographical zone will be for-
warded. But the geographical zone will still be required to ensure communication with the
room unit. The geographical zone must have a different setting value.
