Review Battery Tips
1. Replace the batteries as soon as LO Batt flashes in
the display. The LO Battery indicator flashes in the
display one month before the batteries run down
completely.
2. Always use fresh AA alkaline batteries. Non-alka-
line batteries do not last as long and can leak,
causing thermostat damage.
3. Although the thermostat has a Low Battery indica-
tor, replace the batteries once a year to prevent the
thermostat and heating/cooling system from shut-
ting down due to lack of battery power.
4. As a precaution, replace the batteries when leaving
your home for more than a month to prevent your
heating/cooling system from shutting down if the
batteries run down completely.
