Battery replacement
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
BATT LO
warning begins flashing. The warning flashes about 30
days before 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.
