Hello Jung,

Thanks for reaching out to the Google Nest Community. 

I’d be happy to help you with the Nest Learning Thermostat. Let’s check it out.

A few questions: what country are you located in? What is the make and model of the existing thermostat? What kind of HVAC system do you have? Also, what is the make and model of the HVAC?

You can also check your system’s compatibility with our online Compatibility Checker.

Keep me posted.

Best,

Lance

Hello,

I'm located in Michigan USA.

It's a Lennox CX34-30B-6F-2

The thermostat is the "learning thermostat" 

Thanks for your help.

Hi there,

I'm chiming in to see how I can help.

Thanks for sharing the compatibility checker, Lance.

@Jung, we appreciate your efforts in sharing your thermostat's wiring, but we couldn't identify which terminals they are connected to. To have a better look, can you post each color of the wires and which terminals they are installed on? This way, we can assure how they are being labeled. Also, tell us the make and model of your HVAC system so we can check its compatibility with the Nest.

I'll look forward to your response.

Regards,
Mark
