Replacing a regular wall switch, this unit automatically turns lights on when someone enters in a room.
It increases energy savings by automatically turning lights off after only momentary occupancy. An integrated Light-Dependent-Resistor prevents lights from turning on when the room has adequate natural light. The combination of PIR and light-level detection technology provide excellent lighting control reliability. The slide-selector provided for conveniently switching light on/off manually or to enable PIR/CDS to operate automatically.
