Abstract: A load controller, primarily intended for use in systems having geographically distributed, energy utilizing loads, and employing stored energy heating apparatus. The controller (1, 10) disclosed, in conjunction with a stored energy heater (3, 4), when installed on an energy distribution system having a multiplicity of heaters and controllers, adjusts individual heater storage (3), providing adequate energy for varying heat requirements of individual heaters after a mandatory "off" period (46, 47, 49, 51), thereby greatly reducing the overall peak energy or demand requirements on a central energy source. Alternate embodiments utilize a microprocessor (300) to provide close control of heater storage and improve efficiency. Digital display (307) and a keyboard input are provided for adjusting system constants and evaluating unit operation.

Abstract: A load controller, intended for use with a stored energy heating apparatus and similar to that of Specn. No. 2042767A, is described. Further control arrangements use a microprocessor to ensure that a thermal storage heater has received an appropriate charge at the end of a supply "on" period, the processor basing its calculated value of desired storage temperature on the heat store temperature drop during one or more discharge periods, and receiving updated inputs of ambient and storage temperature during a charging period. Digital display and a keyboard input are provided for adjusting system constants and evaluating unit operation. A further refinement permits the processor to ensure that charge rate is limited if a maximum permitted electrical demand of the premises would otherwise be exceeded.
