Abstract
In some embodiments, a controller for a heating, ventilating and air conditioning (HVAC) system comprises an interface and a processor. The interface receives a comfort temperature set point and a sensed temperature for the enclosed space. The comfort temperature set point comprises a single set point used for both heating and cooling mode operation of the HVAC system. The processor determines a total error value based on comparing the sensed temperature and comfort temperature set point, selects a mode of operation based on the total error value, and operates the HVAC system in the selected mode of operation.
