Make sure that it is compatible with your heatingj/cooling system

Just installed yesterday. So far this is exactly what I wanted. Drawback backlight is not automatic, I believe you have to change a setting to get it to work but havent gotten that far.

This was mostly simple to install. One of two things I did not like is how difficult it was to put the wires into their designated spots. I have lady hands, by which are even smaller than standard lady hands and still I struggled with trying to get the wires in. My second issue was that the advertisement mentioned there is a back-lit display. While the screen does display, it is not back-lit and so it does not help to see without turning the light on.

Short cycling..on off every 10 minutes.difficult installation.
