Replacing Batteries - Lennox Commercial Touchscreen Thermostat Owner's Manual

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
recommended that you
replace the batteries once
each year. Do this to prevent leak age and prevent the thermostat and
HVAC system from shutting down due to lack of thermostat battery power.
