Yup. I guess I have 2 problems. 1) finding a contractor who cares and understands. 2) trying to find how the heat pump should be set up. At this point in time, all that I am left with are the factory defaults. What I do not understand at this point is why are York's factory defaults so different from Hitachi. My neighbour's Hitachi was installed with no installer configuration and it works automatically to control fan speed. Here the default is "hot heat pump", so that the fan puts out a constant 79F from the moment that the fan starts.
