Replacing the Battery
A LOW BATTERY WARNING will appear when the battery falls below 10% of its rated capacity.
This procedure does not lose the thermostat settings; however, time settings will require re-
programming if communications are not restored. Replace with a CR-2032 battery.
Many government agencies promote and have battery recycling programs. Contact your local
jurisdictional government agency regarding available recycling programs.
