Additional zones in the RXB/RXL room controller

The RXB/RXL room controllers have not only the "Geographical zone (apartment)"
zone category, but also the "Geographical zone (room)" and "Geographical zone
(subzone)".
For applications with RXB and RXL room controllers, use only the "Geographical
zone (apartment)" and "Geographical zone (room)" categories. For Variant 2
above, these two zone categories can be used for zone addressing as follows:
Ground floor
Stairwell
All IT rooms
Office 1 1. floor
Office 2 1. floor
Office 3 1. floor
Office 4 1. floor
Office 1 2. floor
...
Office 4 4. floor
Laboratory 1 1. floor
Laboratory 2 1. floor
Laboratory 3 1. floor
Laboratory 1 2. floor
...
Laboratory 3 4. floor

Extending addressing by the "geographical zone (room)" results in individual room
control with RXB/RXL room controllers. This allows for individual manual
intervention, e.g. adjustment of the room setpoint in every room (in our example in
every office and lab).
For additional division of the geographical zone (room), the RXB/RXL room
controller offers the geographical zone (subzone). This subzone can be valuable in
lighting installations, to subdivide a "Geographical zone (room)" for example into
the two subzones "lighting along window" and "lighting along hallway" (e.g. EIB
applications). For HVAC applications, the setting subzone =1 can be left
unchanged.
The supplementary labels "(Apartment)", "(Room)" and "(Subzone)" are predefined
by KNX, where "Apartment" does not denote an actual apartment.
