D = Device address, G = Geographical zone (Apartment . Room . Subzone).
On the KNX bus, several rooms are summarized in a room group via geographical
zone addressing. This address comprises three parts:
Geographical zone: Apartment . Room . Subzone
A geographical zone must be assigned:
– To each RXB room controller.
– To each room group of the RMB795 control station.
Here, all devices to be part of the same room group must have the same
apartment number.
The RMB795 control unit only allows for setting the room group, i.e. the geographical
zone (apartment).
