Abstract: The present disclosure relates to a heating, ventilation, and air conditioning (HVAC) system (100) that includes a heat exchanger (334, 336) configured to circulate a working fluid therethrough, a valve (346, 352) configured to regulate a flow rate of the working fluid through the heat exchanger (334, 336), and a valve controller (602) configured to modify a valve position control signal (636) received from an external controller, separate from the valve controller (602), based on a temperature differential of the working fluid entering and exiting the heat exchanger (334, 336).
