No, the window/door contact cannot be registered directly with the DuoFern radiator actuator. However, the devices can be linked to each other via the Homepilot so that the set target temperature is reduced when a window is opened. When the window is closed again, the radiator actuator returns to the previously set temperature.
Direct registration of the window/door contact on the DuoFern DuoFern Room Thermostat 9485 is possible. The mode of operation is the same as described above for the radiator actuator.
