Input, and the Setpoint Shift Input as well as the optional wall-
mounted sensor’s setpoint adjustment dial. As always, network
inputs have priority over hardwired connections.
The UVC determines if heating or cooling is required based
on the current unit mode (Heat/ Cool Mode Output) and then
calculates the required setpoint for heating or cooling. After
