Up to 8 room thermostats and up to 20 actuators can be connected to the controller terminal bar. The room thermostat measures the actual temperature in the corresponding rooms. The reference temperature is adjusted by means of the keys of the room thermostat. The room thermostat then switches the thermostatic actuator via the controller terminal bar to control the heating circuit at the manifold.
Room thermostats D-BAT require a cable 2 x 0.5 mm², room thermostats D-230 a cable 3 x 0.5 mm².
It is also possible to connect a pump. When all actuators are de-energised (closed), the pump is switched off.
