Function "Time switch operation"
If the room occupancy times for various "geographical zones" are identical, one
controller can be defined as the time switch master.
The other controller or controllers act as slaves, and adopt the occupancy times in
the master.

With regard to room occupancy times, the "Heating circuit 2" controller is the slave
of the controller of "Ventilation 1", because the setting "Time sw. slave (apartm.) =
1" means that time switch operation is adopted by "Geogr. Zone = 1" i.e. by the
controller of "Ventilation 1".
In terms of the room operating mode, the "Heating circuit 2" controller operates
autonomously, see "Geogr. zone = ----" in the illustration.
Only one controller may be the time switch master in any one zone. The setting for
the master is "TS slave (apartm.) = ----".
A time switch master can control one or more time switch slaves in different zones.
The setting for the slaves is "TS slave (apartm.) = x" where x = 1…126, the zone
address of the time master.
For a detailed description of time switch operation with the RMU7x0B controller,
see the technical principles document P3150.
Communication via zone addresses for specific devices is described in the basic
documentation for the Synco 700 RM… controllers. These descriptions are all in
the "Communication" section.
