LOW
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 flashing on the
screen for 21 days (if the batteries are not changed). If the bat-
teries are not changed 22 days after the thermostat detects low
battery voltage, the thermostat screen will only show the flash-
ing 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 flashing bat-
tery icon until buttons are pressed and the set points will offset
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 flashing,
temperature offset 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 be-
come inoperable until new batteries are installed.
