Yes, this is possible. The room thermostat is installed in the respective room and supplied with 230 volts. A universal actuator 9470-1 or 9470-2 is installed at the heating circuit distributor to which the control valves are connected. The universal actuator is registered to the room thermostat and thus used to control the room. Please note that the universal actuator must not be registered with any other DuoFern transmitter or DuoFern control panel when used in this way. The control should only be carried out by the room thermostat.
