TROUBLESHOOTING

If your thermostat’s display is frozen, blank or displaying incor- rectly, the thermostat may have been affected by static dis- charge or voltage variations. If this happens, press the RESET button (see fig. 2, page 2 for the location of the button). Pressing the RESET button will clear all user programming. The thermo- stat will revert to factory preprogramming. You will need to reset the time and, if desired, reprogram the thermostat to your selected program. If pressing the RESET button does not correct the problem, contact a qualified service technician.

For optimum performance, we recommend replacing batteries once a year with fresh “AA” Energizer® alkaline batteries.
