The low battery indicator is displayed when the
AA battery power is low. If the user fails to
replace the battery within 21 days, the screen
will only show the low battery indicator but
maintain all functionality. If the user fails to
replace the batteries after an additional 21 days
(days 22-42 since rst “low battery” display) the
setpoints will change to 55˚F (Heating) and 85˚F
(Cooling). If the user adjusts the setpoint away
from either of these, it will hold for 4 hours
then return to either 55˚F or 85˚F. After day 63
the batteries must be replaced immediately to
avoid freezing or overheating because the
thermostat will shut the unit o until the
batteries are changed.
