ABSTRACT:
A control circuit for a typical home heating and cooling system is shown. The control circuit includes a standard 24 volt transformer in conjunction with a thermostat selector switch and a fan selector switch. As is common in many heating and cooling systems, a multiple speed blower is included with the higher speed being used during the cooling cycle. In addition to the standard relay for normal operation of the multiple speed blower motor in the typical home heating and cooling system, the control circuit includes an economizer control relay. The economizer control relay activates when the thermostat selector switch is in the cool position and the fan selector switch is ON to cause the blower motor to run at a high speed while the compressor is running and at a low speed while the compressor is not running.
