Product information

The user interfaces CR 400, CW 400 and CW 800 are
collectively referred to as C 400/C 800.
The C 400 user interface makes it easy to operate your C 800
heating system. Turn the selector to set the required room
temperature in your home. The thermostatic valves only need
to be adjusted if an individual room is too cold or too hot.
Automatic mode with the adjustable time program ensures
energy-efficient operation by reducing the room temperature
at certain times or by shutting down the entire heating system
(adjustable reduced temperature). This method of controlling
the heating optimises thermal comfort whilst minimising
energy consumption.
DHW heating can be adjusted conveniently and controlled
efficiently.
