The function is supported by the room thermostat version 2 in conjunction with radiator actuators version 2.
A room thermostat 2 can centrally control up to 20 DuoFern radiator actuators 2. The individual radiator actuators 2 are registered on the room thermostat. The setpoint temperature is used identically for all radiator actuators 2. In this application, you also have the option of specifying whether the actual temperature is also measured by the room thermostat or by the respective radiator actuator. As a rule, it makes sense to have the temperature measured by each radiator actuator 2 itself, but if the actuators are operated in niches or very cold walls, the measured temperature may deviate. In this case, the actual temperature from the room thermostat can be used.
The changeover is made on the respective radiator actuator in the menu item SEn = Sensor external.
OFF equals measurement in the radiator actuator,
ON = measurement in the room thermostat.
The control can be done at the room thermostat itself or alternatively via the HomePilot. If the HomePilot is used for time control, item 1 is selected in menu item 9-9-2.
