Abstract: A system for selectively providing power from a power source to a load to operate in an area for at least one occupant comprising a processing device for controlling the opening and closing of a relay connected between the load and the power source for energizing the load, and a sensor for detecting the presence of an occupant in the area. The processing device is programmable to close the relay in response to an output signal from the sensor for a period of time that can be of fixed duration, or a duration that is dynamically and automatically determined using sensor data relating to measure time between successive, detected occupant movements. In addition to a daylight inhibit function, the system is provided with color indicators and a tone generator to indicate various operating conditions and to guide a user entering selected system parameters, among other features.
