Abstract
The single zone lighting controller controls the lights in a zone or area integrating external control signals for daylighting and occupancy with a local override function. The daylighting signal is from a master photoelectric control, and occupancy signal is from a time-clock or electronic occupancy sensor; the local override, activated by an occupant provides a fixed override period before the single zone lighting controlled again responds to the external control signals. Shortly before the override period is over, the single zone lighting controller warns the occupant, e.g., by blinking the lights that the override is about to end.
