Tempstar high efficiency 7000 furnace with a Honeywell 5-1-1 day thermostat upgrade to the Gen 4 Nes

[Canoli]

The tempstar 7000 has the green wire on terminal G and the Honeywell 5-1-1 thermostat has the green wire on terminal B. When connecting the nest do I connect the green wire to the B terminal or the green terminal?

Hello Canoli, 

Thanks for reaching out to the Google Nest Community Forum. It seems you have concerns about the wiring configuration to install in the Nest Learning Thermostat 4th Gen. So don’t worry. I would be more than pleased to help. 

To get a better understanding of the situation, help me out by providing this information. 

• Could you attach a picture of your wiring system, the current wiring configuration, and the previous one installed in the Honeywell? 

This information will help determine how to install it. Any additional details you can provide will also be helpful.

Best regards, 

Daniel
