Important:
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 first “low battery” display) the set points will change to SS°F(Heating) and 8S°F(Cooling). If the user adjusts these setpoints away from these it will hold for 4 hours then return to either SS°F or 8S0 F. After day 84 the batteries must be replaced immediately to avoid freezing or overheating because the thermostat will shut the unit off until the battery is changed.
