Abstract
A method for calibrating a flow sensor in a heating, ventilation, or air conditioning (HVAC) system. The method includes receiving, at a controller, a request to enter a calibration mode and, in response to receiving the request, automatically commanding a flow control device to achieve a target flow rate. The method further includes generating, by the controller, calibration data for the flow sensor using a reference flow value of the flow rate when the flow control device has achieved the target flow rate and a corresponding flow measurement from the flow sensor.
