ABSTRACT:
An apparatus and method are provided for determining the temperature of an operating fluid media in an HVAC system. An integral temperature sensor, mounted within an actuator of an actuator-driven HVAC valve, senses the temperature of a valve body of the HVAC valve. The temperature of a fluid media within the HVAC valve is determined from the temperature of the valve body. A processor within the actuator configures the actuator to function in either a direct acting mode, or alternatively in a reverse acting mode, as a function of the temperature of the valve body as sensed by the integral temperature sensor. The actuator is adapted for attachment to the HVAC valve in such a manner that the temperature sensor is placed in operative thermal contact with the valve body by the act of attaching the actuator to the HVAC valve.
