Abstract
An HVAC system for a comfort zone includes a compressor, temperature sensor and controller. The controller is configured to receive a starting temperature from the temperature sensor, receive a desired temperature, and receive a desired time for the comfort zone to reach the desired temperature. The controller is further configured to determine a starting time to adjust cooling the comfort zone, the starting time determined based at least on the desired time, the desired temperature, the starting temperature, and a most-energy-efficient operating speed of the compressor. Once the starting time has been reached, the controller is further configured to communicate a command to the HVAC system to operate the compressor at the most-energy-efficient operating speed.
