A program or subprogram in a processor, thermostat or computer that directs a temperature control system either contains or is programmable to contain an approximation that is applied to a setpoint temperature. In a heating environment, where a temperature setpoint is X degrees F. (X° F.), the approximation will assert a setpoint range of X-yF° (wherein y is the setpoint variation or approximation) such that when the actual temperature reaches X-y° F., the system will only then start the heating process when that X-y° F. temperature is reached. When the temperature control system is a cooling system, where a temperature setpoint is X degrees F. (X° F.), the approximation will assert a setpoint range of X+y° F. (wherein y is the setpoint variation or approximation) such that when the actual temperature reaches X+y° F., the system will only then start the cooling process when that X+y° F. temperature is reached. The significance of the process is that when a single absolute point temperature is selected, the start up event of heating or cooling is reached more frequently over a given period of time.
