Abstract
A method of controlling an HVAC system including programming a thermostat of the HVAC system to define a temperature set point, a temperature differential around the temperature set point, and a number of cycles per hour for a temperature control source of the HVAC system. The method also includes sensing a temperature, executing a cycling control algorithm that includes the temperature, the temperature set point, and the number of cycles per hour as inputs to determine a duty cycle, and running the temperature control source according to the duty cycle when the temperature is within the temperature differential. The method further includes executing a deadband algorithm to turn on the temperature control source when the temperature is outside of the temperature differential at one extreme and to turn off the temperature control source when the temperature is outside the temperature differential at the opposite extreme.
