Facts About Your Occupancy Sensing Light Switch
The occupancy sensing light switch purchased through the Office Equipment Efficiency Program will save energy on room lighting when you are away. It senses your presence, and after you leave the work area it turns off the overhead lights. When you return, the lights come back on.
Things to keep in mind:
The Watt Stopper WS 120/277 lighting control is a passive infrared device - it works by "seeing" your body heat and movements. It will sense you walking around even across a large room. However, to dependably sense small movements of reading or typing, it should be no more than ten feet from your desk. Also, make sure that your hands and arms are not hidden from the sensor by a large workstation or other obstructions.
This device is not appropriate for wall switch locations that would allow it to see out the door. It would then turn on the lights every time someone walks past. If the doorway is near the edge of the unit's 180 degree field of view, it can be masked out with the opaque adhesive tape supplied.
The sensor will shut off the lights at a preset time after it last sees you. You can set this delay from 2 to 30 minutes. The best settings are in the 10 to 15 minute range. This retains a high degree of energy savings, but avoids putting you in the dark if you are especially still for a few minutes.
The sensor accounts for ambient light levels; if you have lots of daylight in your office, the sensor will not turn on the lights. You can adjust the level of ambient light that will cause the overhead lights to remain off. And if sometimes you want the overhead lights to come on even with lots of ambient light, simply hold your hand over the sensor for a second, or hit the "on" button.
This light switch has been provided as part of the Office Equipment Efficiency Program. This program is managed by Energy Solutions of Oakland, CA, in partnership with The Watt Stopper®, Inc. This program is funded by California utility customers and administered by Pacific Gas and Electric Company, under the auspices of the California Public Utilities Commission.
