If your thermostat is behaving erratically or something strange is in the display, pressing the reset buttons can often correct the problem.

*If this does not correct the problem, proceed to a Software Reset

- Open the door on the front of the thermostat and look for the small round recessed button labeled “RESET”
- Hold this button down for at least 5 seconds.
- The screen should fully populate temporarily.
- You will see all 8888’s in the display. Correct the day and time and then set your heating and/or cooling schedules.
