4. Use the compatibility checker
If you haven't already, go to
and enter your thermostat's wires into the
compatibility checker.
• Enter only the connectors on your
thermostat that have wires in them
• Do not use wire colors – enter the
connector labels
• Do not enter any jumper wires into
the checker (see step 5)
If your system is compatible, you'll get a
custom wiring diagram that you will need
to install your Nest Thermostat. You can
print it or email it to yourself.
