Battery replacement

Batteries are optional if your thermostat
was wired for AC power when installed.
Install fresh batteries immediately when
the REPLACE BATT warning begins flashing.
Even if the warning does not appear, you
should replace batteries once a year,
or before leaving home for more than a
month.
Batteries provide backup power to the
display during power interruptions.
All settings are permanently stored in
memory, and do not require battery power.
