6.11.4 Optional accessories
Room station RS-T
The Room station RS-T offers additional operating convenience through decen-
tralised 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 modified
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 heat-
ing, reduced heating or automatic mode according to a preset automatic program
stored in the central unit.
