Depending on what kind of T-Stat you have.
A regular manual T-Stat is set to come on and off within 2 to 3 degrees below and above set. If it exceeds that....you need a new one.
If it's a digital T-Sat, they are normally 2 degrees above or below set. Again if it exceeds that....1st try changing the batteries. If it still does it, I would change it to a manual T-Stat
