An energy management and home automation system includes one or more controllers in each facility being managed and one or more energy consuming devices attached to each controller. Each controller responds to digital paging signals from a central command center which establish a schedule of event effecting the operation of each device and the controller schedules each device to be operated pursuant to the programmed schedule. The user of the system, by appropriate communication with the command center, may cause a paging message to be provided at any time changing the pre-programmed schedule. The heating/cooling system is controlled by setpoint temperatures for each of a plurality of different modes of occupancy, whereby the most energy is consumed when the facility is occupied and lesser amounts of energy are consumed when the facility is empty. Intermediate amounts of energy are consumed when the facility is not fully operational because people are asleep or maintenance or cleaning is being done. Prior to a mode change which demands more energy, the controller calculates the time required to bring the facility to the setpoints for the new mode and operates the heating/cooling unit at the calculated time prior to the scheduled mode change. The calculation is based upon the time required for the heating/cooling being controlled to change the temperature in the facility being managed. The energy consumption of the facility may also be reduced by paging messages from the utility company as a part of an emergency load reduction program.

A method for controlling the operation of a plurality of devices in a plurality of different facilities pursuant to programmed commands of an occupant of each facility, said method comprising: providing a controller in each facility within a defined wide area, each controller having a plurality of individual devices connected thereto; providing a command center which generates messages to be transmitted to each of said controllers, each message containing a portion defining whether that message is of a first type designated for all controllers or of a second type for designated only an addressed controller; transmitting on a periodic basis said first type of messages conveying the then occurring time and day; transmitting said second type of message to an addressed facility in response to a qualified communication from the occupant of that addressed facility; and storing a schedule in the addressed controller of the communicating occupant\s facility in response to said transmitted second type of messages, said schedule defining the occurrence of events for each device connected to the user\s controller by time and day.
