5. Label wires
Peel off the blue labels and attach them to
your wires. Use the white labels if you have a
E, W3, HUM or DEHUM wire. You can connect
only one of these wires to Nest’s
*
connector.
6. Disconnect wires and
remove base
7. Mark where screws will go
Use the bubble level to make sure Nest
is level.
HUM and DEHUM wires may require a
professional. Check at nest.com/works
Tip: Take a
picture of the
wires on your
old thermostat
to help you
remember.
Tip: Wrap the wires around a pencil to
keep them from falling into the wall.
