The radio connection system FV1 is optimised for the wireless transmission of switching states.

The radio connection transmitter FV2 S has 4 inputs for connecting external contacts/sensors. Any changes in the signals at the inputs of the transmitter FV2 S are transmitted directly by wireless transmission to the relay contacts of one or more radio-controlled switches of the FV2 system. The radio messages are transmitted only when the state of an input changes or at defined time intervals.

Application:
Expansion of existing electrical installations, e.g. switching additional lamps with an existing lamp, transmitting the contact of a motion sensor to several lamps, transmitting the status of a heater thermostat to a control valve and forwarding status and fault signals (door open, heating off etc.) by wireless transmission.
