Replacing thermostat batteries
Install fresh batteries when the REPLACE
BATTERIES warning begins flashing. The
warning flashes about 60 days before
batteries are depleted.
Even if the warning does not appear, it is
recommended to replace batteries once a
year, or before leaving home for more than
a month.
Press the release button on top of the
thermostat to remove it from the wall plate.
Install 4 fresh AA alkaline batteries.
