For implementation of the application example, we focus on the floor plan of Sport Ltd.
Due to company needs, a subdivision into 2 room groups or 2 "geographical zones
(apartment)" is made:
– Conference room (room group 1)
– All the other rooms are offices (room group 2)
The fan coils, all of which are equipped with RXB room controllers, are already shown
on the floor plan, and the appropriate assignments by means of addresses have been
made:

Raumgruppe 2
Room group 2
D = device address, G = geographical zone (Apartment.Room.Subzone)
The combination of several groups to 1 room group is made on the KNX bus by
addressing the "Geographical zone". This address consists of 3 components:
Geographical zone: Apartment.Room.Subzone (e.g. 2.1.1)
A geographical zone must be assigned to:
– Each RXB room controller
– Each room group in the RMB795 central control unit
All devices which, together, shall form one room group must be assigned the same
apartment number.
