The zones to be defined are as follows:
Zone in which an RDU KNX 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
like operating mode, setpoints, room temperature, etc.
The designations "Apartment", "Room" and "Subzone" do not need to
be taken literally. For example, Apartment can be used to refer to a
group of rooms, floor or section of a building. "Room", however, really
does refer to a room.
Subzone is not used for HVAC devices. It is more relevant to other
disciplines, such as lighting. Subzone is fix at "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 will use the information 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 RMB975 central control unit.
The zones are divided in so
called "Room groups" (e.g. 1...4),
where each "Room group" can
have an individual schedule. A
room thermostat in the same
"Room group" need to have the
same Apartment Address.

This Distribution zone is for air applications (VAV, CAV). Information
related specifically to the air handling system is exchanged within this
zone (e.g. air demand). This zone also includes a Synco device to
process the information (e.g. RMU7xx).
Outside temperature received in outside temperature zone 1 will be /
can be displayed on the room thermostat when commissioned
accordingly (parameter P07 = 2).
