Nest Learning Compatability

[JeffreyP]

Good Morning, 

My Google Nest Learning Thermostats just showed up and I realized the wiring for each is different. I believe one is compatible and one I’m not sure about. 

Each has C W G Y and R cables. The downstairs one has a U1 orange cable and I’m not sure what to do with that. Unfortunately when I checked compatibility before purchasing I only looked at the one without the Orange (U1) cable. Any help would be greatly appreciated. Thx.
