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.
A method for determining the temperature of a valve body of an actuator-driven HVAC valve in a heating ventilation and air conditioning system (HVAC valve), the method comprising:
An apparatus for determining a temperature of a valve body of an actuator-driven HVAC valve in a heating ventilation and air conditioning (HVAC) system, the apparatus comprising, an actuator adapted for attachment to the HVAC valve and for controlling the HVAC valve, the actuator having an integral temperature sensor for sensing the temperature of the valve body when the actuator is attached to the HVAC valve, and a processor operatively connected to the temperature sensor, the processor programmed to determine a media temperature of a media within the valve body from the temperature of the valve body.
An apparatus for controlling a flow of fluid from a source of fluid in a heating ventilation and air conditioning (HVAC) system, the apparatus comprising:
