Caution
Special Thermostat Battery Cautions
Always replace the batteries as soon as the low battery indicator displays. The thermostat is a battery powered
device. You must be responsible to replace batteries before they run out. Failure to replace batteries can result
in overheating or excessive cooling of your house.
• Even if the low battery indicator display does not display, you should always replace the batteries at least once
a year. Replacing the batteries also helps to prevent leakage that can corrode and damage the thermostat.
• If you are leaving your home for a month or more, you should replace the batteries as a precaution against
battery failure in your absence.
