Abstract
An environmental control system includes a plurality of electronically controlled zone controllers mounted on local VAV boxes for regulating the lighting, temperature and ventilation in a plurality of small zone areas. Each zone controller includes a timer which may be adjusted dynamically to change environmental requirements for zone occupants. A remote master computer is coupled to each local controller to provide three modes of lighting and HVAC equipment control. The inventive method of using the system includes controlling selectively individual ones of the zone controllers to provide three modes of operation an OCCUPIED mode, a STANDBY mode, and an UNOCCUPIED mode where the time period for each mode is adjustable either locally from the zone or remotely from a remote console.
