The range of DuoFern transmitters in the building is up to 20m.
BUT more importantly, with the DuoFern system we offer a self-configuring routing function. That is, each 230 volt DuoFern device, whether belt winder, switch actuator or radio tubular motor is a repeater and helps to transmit the data if a direct connection can not be established immediately. This routing runs completely automatically without further configuration. In this way, even greater distances can be bridged and positions can be reached that are normally not ideal in terms of radio technology. Basement rooms, for example.
If a distance is too great, another 230 volt DuoFern device can simply be added to the route and the device can be reached.
