Important:
The low battery icon is displayed when the AA battery power is low. Whenever the
thermostat detects low battery voltage from the AA batteries, the low battery icon
will begin ashing on the screen for 21 days (if the batteries are not changed). If the
batteries are not changed 22 days after the thermostat detects low battery voltage, the
thermostat screen will only show the ashing battery icon until buttons are pressed. If
the batteries are not changed 43 days after the thermostat detects low battery voltage,
the thermostat screen will only show the ashing battery icon until buttons are pressed
and the set points will oset to 85°F/29°C in cooling and 55°F/13°C in heating. At this
stage, set point changes can be made temporarily but, the set points will change back
to defaulted values after a 4-hour period. The thermostat will continue to perform this
low battery ashing, temperature oset condition until the internal voltage threshold
is reached. When the thermostat internal voltage threshold is reached, all relays will be
opened and the thermostat will become inoperable until new batteries are installed.
