I can see you've got Y, G, C, W1 and R wires. What's the red wire labelled as?

Welcome to the Google Nest community! We’re going to need some more information from you to be able to help you. Please can you share a photo of your current wiring setup? What brand and model of thermostat is it?

Oops I posted a photo but it doesn’t look like it’s there. It’s a Honeywell ProSeries thermostat

The red cable is O/B

It sounds like you have a dual fuel system, like a heat pump and a furnace. If you’re not sure, check here. Regardless, based on those wires it should be compatible with all the models of Nest Thermostat.
