Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
I just installed a rth7500 about a week ago. Prior to this the AC worked great. The house cooled quick and the unit cycled on and off when needed. Since I put in the new stat the unit runs all day and the house does not go under 78 until about 11pm. I had a service guy out a few weeks ago to check the outside unit and everything was fine. I never had this problem with the last stat. Could there be a problem with the wiring? Any ideas? Thank you.
A/c is either on or off,there no in between.check air filters make sure they are clean.also keep in mind a/c will only bring temp down about 15 degrees from outdoor temp
