Replacing Batteries, thermostat stops operating

Page 14 highlights

Replacing Batteries With proper power and connections, the thermostat does not require batteries. Thermostats with batteries provide a warning when the batteries run low. This warning flashes on the main screen for approximately 30 days. NOTES: - - If batteries are not replaced when Low Battery warning is flashing, the LO batt screen displays continuously and thermostat stops operating M22383 until batteries are replaced. Despite the low battery indicator, it is recommended that you replace the batteries once each year. Do this to prevent leakage and to prevent the thermostat and HVAC system from shutting down due to lack of thermostat battery power. 14 63-2626
