The room thermostat 2 can be connected directly to the radiator actuators 2.
One room thermostat 2 can centrally control up to 20 DuoFern radiator actuators 2. The individual radiator actuators 2 are registered with the room thermostat.
The setpoint temperature is used identically for all radiator actuators. 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 takes place at the respective radiator actuator.
In addition, the interaction with several DuoFern window/door contacts has been improved. The temperature is reduced to 4°C when one or more windows are open. Only when all windows are closed again, the temperature is regulated to the last set temperature.
An update of the room thermostat is not possible.
