I had recently moved my stat to a different area. I now have trouble w/the temp. I have the a/c on and it says it is 74 in the house but my other stat says 77 and it is accurate. I tried to "reboot it", but it doesnt work right. The a/c stays and only drops 1 degree and doesn't get close to the temp I set it at. Can u help me? I did the factory defaults and it still doesn't work right.
