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
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.
