ABSTRACT:
A remote control system for operating electrical loads, particularly in multi-unit lodging establishments such as hotels, motels and the like, includes a power sensing circuit for deenergizing the loads when the power supplied varies beyond predetermined limits in voltage or phase, a restart circuit for sequentially reenergizing the loads with the time between reenergization of loads on successive buses being dependent upon the period of time the loads were deenergized in order not to produce an overload by simultaneous load operation under peak demand conditions, a start-up circuit for controlling the cycle period of the loads in accordance with outdoor temperature in order to provide efficient freeze protection and temperature maintenance, an excess manual switching circuit for comparing the number of loads presently energized with the number of loads energized at a predetermined prior time plus a preset number representing the maximum number of loads desired to be energized over the predetermined period of time such that if the number of presently energized loads exceeds the desired number of energized loads over the predetermined time no additional loads can be manually switched on-line until the number of presently energized loads is reduced below the desired number of energized loads thereby increasing electrical efficiency.
