Nest Compatibility Photo

[Jeff6619]

Compatibility checker was inconclusive.  Said to post a photo here.  I have no attachment or insert picture photo so putting it in a link.  Can anyone help?

Hello Jeff6619,

Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look at this for you.

I appreciate your effort in attaching your existing thermostat's wiring setup. Unfortunately, I can't determine the other wiring labels.

Can you share with us other pictures of its wiring showing its configuration? Also, what type of HVAC system do you have? (conventional, heat pump, etc.)

Keep me posted.

Best,
Mark
