Abstract: A method and means for creating a daylight harvesting controller with a self calibrating light sensor and an adaptive setpoint that maintains a user determined light level is disclosed herein. The system includes a light sensor for monitoring the ambient light level of a designated control zone and a means to receive and interpret light level adjustment commands created by a user or user surrogate. The system includes means to limit the setpoint to a maximum value, suspend daylighting activity when lights are being adjusted or are turned off, and to delay setpoint capture and the start or resumption of daylighting until an adjustment cycle is completed and the zone light sources have reached a nominally steady state.

Abstract: An improved occupancy based, object oriented, load management system using anonymous, stateless messaging to communicate real and simulated occupancy detection events between control objects hosted by a plethora of control devices.
