I have white Rodgers 80 series thermostat. I think it has been programmed by itself or accidentally. I think it turns on by itself and the desired temperature changes. How can I reset the program.

I had the exact same problem. Even pressing the Hold button does not really help, because once it resets - the Hold temperature also changes to the default.

I fixed this by replacing the 470 micro-Farad / 10v capacitor in the unit (it's the grey-colored capacitor). To access the back of the circuit board, you will need to break 2 plastic rivets holding the front of the unit to the base.

After replacing the capacitor I've not had any resets for the past 3 days (it used to reset itself every couple of hours).

Hope this helps.
