Lennox signatureStat to Nest

Trying to check on compatibility going from a Lennox signature Stat to a nest 

[Patrick_Caezza]

Your current thermostat is compatible with any Nest Thermostat.

Give this a try.

Black - C to C

Red - R to Rc or R 

Blue - Y1 to Y1 or Y

White - E/W1 to W1 or W

Yellow Y2 to Y2 or */OB

Green - G to G

The "or" is for the Google Nest Thermostat

Thanks. The info worked fine. But I have a total of three of these signature stats. The other two had an extra wire labeled “D”

Hey Ladderpx311,

Thanks for your reply.

When you're done with connecting all necessary wires to your Nest Thermostat and it is already up and running,  it's time to check the main board for the D wire. This way, we can tell if you no longer need to connect that specific wire.

Best regards,

Ryan
