Abstract
Apparatus and a method for providing failsafe supplemental heat operation of an air conditioning control are disclosed. Operating power to a microprocessor control is discontinued when the air conditioning unit is placed in a supplemental heat mode by the user. The microprocessor control is so arranged that appropriate connections are made to operate a supplemental heat source in response to a first stage heating need being sensed by the thermostat when operating power to the microprocessor control is discontinued. Under normal conditions multiple stage heating operation is provided with a supplemental heat source being operated under control of a programmed microprocessor.
