3.10.3 Zone addressing in LTE-Mode (in connection with
Synco)
In cases where RDG..KNX room thermostats are used in LTE-Mode (e.g. in
connection with Synco), zone addresses need to be allocated.
The following zone addresses must be defined together with the Synco devices at
the planning stage depending on the application:
Short description
Factory setting
Parameter
Geographical zone (apartment)
--- (out of service)
P82
Geographical zone (room)

P83
Heat distribution zone heating coil
--- (out of service)
P84
Refr distribution zone cooling coil
--- (out of service)
P85
Heat distribution zone heating surface

P86
Air distribution zone
--- (out of service)
P87
"Subzone" of "Geographical zone" is fix 1 (not adjustable).
The device sends and receives LTE communication signals only if the zone
address is valid (not OSV = out of service).
The zones to be defined are as follows:
Geographical zone
(space zone)
(Apartment . Room . Subzone)
Apartment = ---, 1...126
Room
= ---, 1...63
Subzone = fix 1
Zone in which an RDG..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 uses 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 RMB795 central control unit.
The zones are divided into 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.
