A strategic response control for an air conditioning system for use in an environment with increased power rates during a designated peak period. The air conditioning system includes a power board for operating the air conditioning system in one or more operating status having a controller with a processor and a real time clock, an indoor temperature sensor for generating an input signal representing the indoor temperature, an outdoor temperature sensor for generating an input signal representing the outdoor temperature, and an operating program that sets a maximum comfort level temperature, a minimum comfort level temperature and a warmup rate for the environment in which the air conditioner operates, and has a procedure for precooling the environment before the peak period, wherein on activation, the processor signals the power board to enter an operating state for precooling and an 'off' or lower level operating state during the peak period.

Strategic-response control system for regulating air conditioners for economic operation

A speed controller for a single phase motor such as a permanent split capacitor motor allows the motor to be operated at a first speed, n , and a lower speed, n . High speed motor operation is produced by passing a single phase AC current through both the main and auxiliary windings of the motor. For low speed operation, the controller passes first and second reduced frequency AC waveforms through the motor's auxiliary and main windings, respectively. The first waveform bypasses the motor's auxiliary winding capacitor and is phase shifted 90 degrees from the second AC waveform. A split source capable of generating an AC signal and its inverted signal can be used by the controller to generate the reduced frequency waveforms. Specifically, the controller uses selected half cycles from each split source signal to produce the reduced frequency waveforms.
