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.
