Nest isn't compatable

[GRB2980]

I used the wiring compatibility guide before I purchased my Nest Thermostat.  I clicked all the wires I have in my current thermostat and Google said the Nest Thermostat would be fine.

Today I tried to install it.  First of all the box, the instructions inside the box, and the Nest itself are all written in Spanish.  I don't speak Spanish.

Second during the installation, the app asked me to describe the wires I had which I did and It came back saying that the Nest is incompatible.  That's when I noticed that my system has 7 wires.  This Nest only has space for 6.  I would post pics of my existing system, but I can't see a way to do that.

My existing system has:

Orange wire connected to O

Red wire connected to R

Yellow wire connected to Y1

Brown wire connected to E/W1

White wire connected to W2

Green wire connected to G

Blue wire connected to C

Does Google make a thermostat that will work with my current setup?

I suspect you've purchased the Nest Thermostat (2020 model), setup with the Google Home app, which isn't compatible with your system. You need a Nest Learning Thermostat, which is setup in the Nest app.

So what do I do with the 7th wire?

Will a Nest Learning Thermostat work in this situation?

The best thing to do is use the compatibility checker:
