It might be hard to see, but there is also a green wire that my current thermostat doesn't use

That seems like it’s a sensor or secondary thermostat of sort maybe connected to zoning system not sure if nest would work

Hi folks,
Thanks for posting in the Google Nest Community forum. Could you please share with us the photo of your system control board and ensure that the labels where the wires connected are visible? It will help us to see the compatibility of your system to the Nest Thermostats.
I appreciate the input, @HVAC.
Best,
Jenelyn
