LTE zones, filter tables, etc.), see "Communication via the KNX bus for Synco
700, 900 and RXB/RXL, Basic Documentation" [6]
∂ LTE mode data points and settings are described in the Synco Application
Manual [12]

3.10.3 Zone addressing in LTE mode (in conjunction with
Synco)
In cases where RDU KNX room thermostats are used in LTE mode (e.g. in
conjunction with Synco), zone addresses need to be allocated.
The following zone address 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) 1 P83
Air distribution zone --- (out of service) P87
Note: “Subzone” of “Geographical zone” is fix 1 (not adjustable)
The device will send and receive LTE communication signals only if the zone
address is valid (not OSV = out of service).
