 For a detailed description of KNX (topology, bus supply, function and setting of
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]
 To engineer and commission a specific system, use the Synco700 planning and
commissioning protocol (XLS table in HIT, [7])
3.10.3 Zone addressing in LTE mode (in conjunction with
Synco)
In cases where RDG 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.
