TSOS5 – The Lights turn ON when using the switch, but doesn’t turn on when in AUTO mode.

Check if there’s activity on the LED indicator when waving your hand in front the sensor (test will work better if your hand is warm). If there is no response, there may be a wiring issue. The TSOS5 requires HOT, LOAD and NEUTRAL wires to work (3 separate wires besides the bare ground wire). Test the wire connection with a multimeter to confirm you have all 3 wires.
