Battery replacement
Install two fresh AAA batteries
when either Lo Batt or battery icon
appears on the screen. The low
battery indicator appears for 60 days
before the batteries 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 preserved when the
thermostat is without batteries.
Set the System switch to Off before removing the
batteries. Otherwise, the heating/cooling system could
remain activated even when batteries are removed.
Pull at bottom to
remove thermostat
from wallplate.
Turn thermostat over,
insert fresh AAA alkaline
batteries, then reinstall
thermostat.
