Battery replacement
Batteries are optional (to provide backup
power) if your thermostat is wired to run on
AC power. If your thermostat is not wired to
run on AC power, then batteries are required.
Install fresh batteries immediately when the
low battery icon appears. The icon appears
about two months before the
batteries are depleted.
Even if the low battery icon
does not appear, you should
replace batteries once a year,
or before leaving home for
more than a month.
If batteries are inserted within
two minutes, the time and day
will not have to be reset. All
other settings are permanently
stored in memory, and do not
require battery power.
NOTE: When replacing
batteries, alkaline batteries are
recommended.
