Install fresh batteries when the REPLACE 

BATT warning begins flashing, once a 

year, or before leaving home for more 

than a month. The warning flashes 

about two months before the batteries 

are depleted.

your thermostat was wired to run on AC 

power when installed. All settings are 

permanently stored in memory, and do 

not require battery power.
