Hello, I Was Wondering If Anyone Can Help Me With This: I Changed The Location Of The Thermostat From One Side Of The Closet To The Other. I Did Not Moved The Cables As They Were Still In Range. I Also Made Sure To Keep The Same Color Of Wire With The Same Input. When I Turn It Back On The Screen Turns On And It Measures The Temperature, But It Does Not Stops On The Set Temperature. The Model Is Simple Comfort Thermostat 2000. Can U Please Help Me Fix This?

Is this your thermostat?

Yes.

So where does the temp stop if not at the set temp?

It does not stop. It continues to run bellow my set temp. that's the issue I need it to stop. The AC does not stop running.

Sounds like there may be a short in the wiring or at the teminals that is bypassing the stat.

Try disconnecting all the wiring and see if that stops the unit from running.
