Questions & Answers

What is the function of the line power reversing switch?

Asked by: Philip
If the sensor fails to operate after the initial warm-up period, use a small flat blade screwdriver to pry off button and slide the line power reversing switch to the opposite position. This will re-initiate the warm-up period. In most cases You will not need to use this switch.

The Wattstopper PW301 Commerical grade sensor is design for "multi-way" application so you could 3 of them for a 4way setup. https://www.legrand.us/wattstopper/sensors/optional-neutral-occupancy-sensors/pw-301.aspx
