Changing The Batteries - Bryant Legacy Owner's Manual

Operating the Thermostat

Changing the batteries

Your thermostat is probably powered by electricity, but if it isn't, it's
battery powered. You can tell if it's battery powered by checking in
Advance Programming Options. (See page 38.) If there's no lighting
until you touch a button, it's battery powered. When the thermostat
uses electricity, the batteries (if installed) take over if the electricity
goes out. This allows you to monitor the indoor temperature when
there's no electricity.
When powered by batteries, your thermostat's two AA batteries should
last about one year. When your batteries have lost about one-third of
their power, a battery icon shows up on the display in the upper right
corner. Two-thirds of it will be black. As the batteries get weaker, the
icon goes down to one bar and then none. When the battery icon
is less than full, you will first see the loss of backlight function. When
the batteries are completely dead, you won't be able to use the
thermostat.
