Abstract
The present disclosure relates to a heating, ventilation, and air conditioning (HVAC) system that includes a heat exchanger configured to circulate a working fluid therethrough, a valve configured to regulate a flow rate of the working fluid through the heat exchanger, and a valve controller configured to modify a valve position control signal received from an external controller, separate from the valve controller, based on a temperature differential of the working fluid entering and exiting the heat exchanger.
