If you are only visiting a room for a short time you can operate the wall switch. The lights will then just stay ON for just 30 seconds before switching OFF. This can save more energy as the occupancy switch does not stay on for the rest of its set time lag. After 30 seconds, any other detected movement will bring the lights ON again, for the regular set time lag.



This can also save more energy by switching the lights OFF before the regular time lag has elapsed. If you press the wall switch when you leave, the lights will remain ON for 30 seconds for you to vacate, and then switch OFF. Again, any other detected movement after the 30 seconds will bring the lights back ON for the regular set time lag.

If you do not use the wall switch at all, the product will operate as a standard PIR Occupancy (presence) switch.
