If your heating and cooling functions are reversed, there are several potential causes and solutions: * If you have a heat pump system, change the O/B reversing valve setting in the thermostat’s settings. * Ensure the W wire and Y wire are connected to the correct terminals on the backplate. * If you are using the PEK, verify the wires are connected to the correct terminals on the HVAC control board and backplate. * Also, ensure that the thermostat is connected to the VeSync app.
