Batteries are optional (to provide backup
power) if your thermostat was wired to run on
AC power when installed.
Install fresh batteries immediately when
the
warning flashes about two months before the
batteries are depleted.
Even if the warning 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.
