BATTERY WARNING
6When the batteries are low, the “LOW
BATT” indicator on the display will flash.
Whenthishappens,installnewbatteries
immediately. Once the “LOW BATT”
indicator appears, the thermostat will
continue to operate for approximately 30
days. (Only alkaline batteries should be
used in your thermostat. Rechargeable
batteries have different properties which
may cause the thermostat to not operate
properly. Do not use old batteries.) The
batteries should last one year.

CAUTION: The batteries are the only source of power used to
operate your thermostat. If you do not replace the batteries, the
display will dim and your system will operate on the last
programmed temperature or the factory default.
NOTE: If you plan to be away from the premises more than 30
days, we recommend that you replace the old batteries with new
alkaline batteries prior to leaving.
