The fan is continuously on. 14 62-3071--2 Replacing Batteries Not all thermostat models require batteries. 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. The thermostat has a low battery indicator. 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. Remove the thermostat from the base by pulling it straight out. 2. Install three new AAA alkaline batteries with proper polarization. NOTES: -- -- Always use AAA alkaline batteries.
