Replacing Your Batteries
Not all thermostat models require batteries. If your thermostat has batteries, a low battery warning
flashes on the home screen for approximately 30 days.
NOTE: If the batteries are not replaced when the Low Battery warning is flashing, the LO batt
screen will display continuously and the thermostat will not operate until the batteries are
replaced.
NOTE: Although the thermostat has a low battery indicator, replace the batteries once each year to
prevent leakage and to prevent the thermostat and heating/cooling system from shutting
down due to lack of battery power in the thermostat.
