Hi, I can tell you the instructions to offset the thermostat. If you pull it off its base plate you can look at the back and it should have a model number. But I am also gonna let you know now, that you can not offset it ten degrees. I think 3 or 5 is the most dependent on the model.

While it is off the wall you should put your hand up on the wall where the hole in the wall is for the thermostat wire and see if it feels like excessive heat is coming through the hole too. The temp sensor tends to be on the back side of the circuit board so sometimes heat coming through the wall will cause it to read higher than actual room temp

I wanted you to get me the model number of the thermostat so I could instruct you how to offset the temp display so your AC will cut off. It is different with different models, that is why I requested you to pull the thermostat off the wall and get the model number
