Energy management system
First Claim
1. An energy management system for reducing the power consumption of a plurality of normally energized loads comprising:
- means providing a source of interrupter actuating voltage;
first timing means having a 168-hour timing cycle;
second timing means having a 24-hour timing cycle;
third timing means having a fractional day timing cycle; and
a plurality of independently acting subcircuits each includinginterrupting means capable of interrupting the flow of energy to a particular one of said plurality of loads,first switching means responsive to said first timing means and operative to apply said actuating voltage to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to its corresponding load during a selected period of said 168-hour timing cycle,second switching means independent of said first switching means but connected in parallel circuit therewith and responsive to said second timing means and operative to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to said corresponding load during a selected period of said 24-hour cycle, andthird switching means independent of said first and second switching means but connected in parallel circuit therewith and responsive to said third timing means and operative to apply said actuating voltage to said interrupting means so as to cause it to interrupt the flow of energy to said corresponding load during a selected portion of the fractional day timing cycle.

Abstract
An energy management system for reducing the power consumption of a plurality of loads and including a seven-day timer, a 24-hour timer and a fractional day timer such as a 30-minute timer, each controlling a plurality of subcircuits such that each subcircuit is operative to interrupt the flow of energy to it'"'"'s associative load at selected times on weekends, in the evening and at synchronized periods throughout the day, the latter periods being synchronized with the other subcircuits, so as to reduce the peak energy demand and to improve the efficiency of the loads. The energy management system further includes circuitry for sequentially shutting down selected loads when the peak energy demand exceeds predetermined levels and circuitry for sequentially energizing the loads following a power failure.
