The zones to be defined are as follows:
Zone in which an RDF800KN../RDF800KN/VB/RDD810KN.. KNX room
thermostat is physically located. Other room-specific devices may also be
located in this zone.
Information exchanged in this zone is related specifically to the device's
operating mode, setpoints, room temperature, and so on.
While the designations "Apartment" and "Subzone" do not need to be taken
literally, "Room" really does refer to a room. For example, Apartment can be
used to refer to a group of rooms, floor or section of a building. Subzone is not
used for HVAC devices. It is better suited for other disciplines, such as lighting.
Subzone is fixed to "1" and not visible.
The time switch information is expected from the same zone where the
thermostat is located (Residential).
If no time switch information is received from the same zone, the thermostat
uses the information it received from the same apartment but with room "1"
A.1.1 (Office).
Example:
Commercial building
In a commercial building, the time switch
information is sent by the RMB795B
central control unit. The zones are divided
into "Room groups" (e.g. 1...4), where
each "Room group" can have an
individual schedule. A room thermostat in
the same "Room group" must have the
same apartment address.

(Apartment.Room.Subzone)
Information related specifically to the hot water system in heating coils is
exchanged within this zone. The zone also includes a Synco device to process
the information (e.g. RMH7xx or RMU7xx with changeover).
Information related specifically to the chilled water system is exchanged within
this zone (e.g. cooling demand). This zone also includes a Synco device to
process the information (e.g. RMU7xx).
The outdoor temperature is provided via KNX bus on zone 31. If available, it is
displayed when the INFO page is selected
