Introduction
The "Geographical zone (apartment)" represents the room to be controlled. Within this zone, all process values relevant to the room are transmitted (e.g. room operating mode, room setpoint and measured room value, plus user intervention and other influences).
Setting values
The factory setting or default value for the RM… series B controllers is "---". This default value indicates that the zone is "out of service", i.e. no relevant process values are transmitted within this zone.
Main menu > Commissioning > Communication > Room
| Operating line | Range | Factory setting or default value |
|---|---|---|
| Geographical zone (apartment) | ----, 1...126 | ---- |
| Time switch slave (apartment) | ----, 1...126 | ---- |
Note
Factory setting or default value "----" applies to all RM… series B controllers.
Autonomous controller
In the "Autonomous controller" application, a ventilation system is controlled independently of other plant, according to its own room operating conditions.
For this application there is no need to set a zone address for the "Geographical zone (apartment)", i.e. the default "---" can be left as is.
Two controllers with identical room occupancy times
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.
Notes
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.
Device-specific communication
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.
The titles and document numbers are as follows:
Universal controller: RMU710B, RMU720B, RMU730B: P3150
Modular heating controllers: RMH760B: P3133
Boiler sequence controller: RMK770: P3132
