Abstract
A microprocessor based control for a heat pump system providing at least two setback temperature settings individually selected by the system user to be effective during different time periods of the day, also individually selectable by the user. In the event of conflicting setback temperature settings during an overlap in the selected time periods, the microprocessor is programmed to implement the setback temperature that provides the most energy efficient operation of the system. Additionally, the microprocessor automatically assures that any setback temperature settings are at least a minimum temperature differential away from the normal temperature setting in the more energy efficient direction. This override provision is effective whether the invalid setback temperature settings are initially inserted by the user or are the result of a subsequent change in the normal temperature setting.
