This thermostat is equipped with a continuous memory feature which does not require any battery. The thermostat will never lose what has been programmed regardless of the length of the power outage. If the thermostat has been set to “Hold” a particular temperature and the power fails, the thermostat will maintain the hold temperature when the power is restored.

After a period of 1 hour without power the clock will need to be reset. The clock will default to 12:00 AM. Refer to the Programming Instructions to reset the clock.

Cleaning

If the surface of the thermostat becomes dirty it can be cleaned with plain water or many non- abrasive household cleaners, such as glass cleaner. When using any cleaner be careful not to get any into the interior of the thermostat. Do not spray any cleaner directly onto the thermostat. Spray the cleaner onto a soft cloth and wipe the surface of the thermostat.
