Abstract

A method of controlling operations of an HVAC system includes measuring temperature within an enclosed space, receiving a setpoint temperature within the enclosed space, calculating a temperature difference between the measured temperature and the received setpoint temperature, and determining whether the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to a first predetermined temperature differential value. If the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to the first predetermined temperature differential value, determining whether the temperature difference between the measured temperature and the received setpoint temperature is greater than or equal to a second predetermined temperature differential value. If the temperature difference between the measured temperature and the received setpoint temperature is less than the second predetermined temperature differential value, selecting a first operating mode of a plurality of operating modes of the HVAC system.
