Battery replacement
Install two fresh AAA batter-
ies when Lo Batt flashes on
the screen. Lo Batt appears
for 60 days before the batter-
ies are depleted.
Replace batteries once a
year, or when you will be away
for more than a month.
The settings are stored in
non-volatile (permanent)
memory and are thus pre-
served when the thermostat
is without batteries.
Pull at bottom to
remove thermostat
from wallplate.
Turn thermostat over,
insert fresh AAA alka-
line batteries, then
reinstall thermostat.
