If the thermostat has batteries, a low battery warning flashes on the main screen for approximately 30 days. NOTES: -- If batteries are not replaced when the Low Battery warning is flashing, the LO batt screen displays continuously and the thermostat stops operating until batteries are replaced. However, it is M22755 recommended that you replace the batteries once each year. Do this to prevent leakage and prevent the thermostat and HVAC system from shutting down due to lack of thermostat battery power. -- 15 62-3071--2 Replace the batteries as follows: 1. All programming (Schedule, Date and Time) information is retained during battery replacement. WALL REMOVE DURING INSTALLATION M19919 16 62-3071--2 3. 4.
