Abstract
A programmable energy load controller system, allowing each of a multiplicity of energy loads to be established in a selected one of an unenergized condition and a plurality of energized conditions, utilizes a central microcomputer facility in communication with a selected one of a plurality of remotely located load control processors, each configured with a unique address and capable of selectively energizing a plurality of energy loads coupled thereto under control of the central facility. The central facility includes at least one user input device, allowing a plurality of maps of load conditions, established in accordance with a user-selectable criteria, such as time-of-day and day-of-week requirements, to be loaded into a data storage associated with the central computer. A real time clock means are utilized in association with the computer and the memory to enable the desired map of load energization under the selected criteria, with means being provided for entering, on a high priority basis, overrides to at least a selected portion of the map currently implemented. Programmable energy load control methods are also disclosed.
