The SL01 light sensor cyclically measures the current brightness level and transmits this via radio.

The light sensor may only be used in connection with the RTS07 time switch or the RCJ02 flush-mounted receiver.

If the sensor battery is running low, this is indicated on the display of the RTS07 radio time switch or the RCJ02 flush-mounted receiver.
