The Passive Infrared RR7 Compatible Occupancy Sensing Wall Switch is a motion sensing lighting control that is used for energy savings and convenience. This low voltage unit interfaces directly with GE RR7 Relay Systems. The ONW-P-1001-RR7 is designed to detect motion from a heat-emitting source (such as a person entering a room) within its field-of-view and automatically switch lights ON. These sensors have multi-segmented lenses. The sensor includes self adaptive technology that continuously self-adjusts sensitivity and time delay in real-time, maximizing the potential energy savings that are available in the particular application. The EcoMeter provides a visual indicator of energy usage, increasing end user awareness and reminding individuals to take control of their lighting to maximize energy savings. HVAC mode allows the load connected to the Form C BAS relay to remain ON when the lights are turned OFF manually.
