I have a newish York DNX packaged gas/electric dual stage A/C unit (installed about two years ago) and I am thinking I might want a better control for it. In particular the control I have is rather basic when it comes to controlling the dual stage cooling, which matters in Arizona. So I'm looking at York's high end toy. Few questions related to that:
1) Would it work with my unit? The specific model is D2NX048N06506NX.
2) How many wires does it need? I have 6 in the wall.
3) In your experience, is it a useful item, or just showy?
4) How do you feel it compares to the funny-looking Nest thermostat, if you've tried both?
Bonus question) If you are in the Tucson area, do you have and install either or both of these? If so, I'd appreciate your contact info.
