Summary:A climate control system includes a control head having a warmer/cooler temperature control for providing relative thermal comfort. A thermal comfort rating (TCR) corresponding to a range of passenger cabin temperatures is determined based upon a comfort level selection by an occupant using the control head. A control strategy employs look-up tables corresponding to the TCR to determine the speed of an electric compressor and the position of a temperature control blend door. The strategy provides for a relatively fast ramp down to a minimum compressor speed to improve fuel economy while maintaining a relative level of thermal comfort.
