6.11.4 Optional accessories
Room station RS-T
The Room station RS-T offers additional operating convenience through de-
centralised monitoring and intervention options, since every heating circuit can
be assigned with its own individual room station. Moreover, the central unit
contains various control and regulating functions which can only be activated
in conjunction with a room station.
The following are some of those functions:
- Optimisation functions
- Automatic heating curve adaption
System specific temperatures and switching times can be checked and modi-
fied via five control keys, also allowing the definition of individual system
programs.
The operation of the room station and the boiler control unit is identical.
Remote setting device with room sensor RFF-T
This auxiliary device monitors the current room temperature and allows the
desired room temperature to be corrected.
With the integrated operating mode key you can select between continuous
heating, reduced heating or automatic mode according to a preset automatic
program stored in the central unit.
