Wireless input can be received from up to six radio power saver vacancy/occupancy sensors and nine pico remotes. For maximum transmitter coverage, the module should be installed in the center of the room. This Lutron PowPak relay RMJ-16R-DV-B is perfect for schools by turning the lights on and off automatically, though it offers many possible applications.
