Thermostat wiring

[Usmc2]

I have 4 wires on my old thermostat. 2 red and 2 black. How do I know if my wiring is compatible with the nest thermostat

Hello Usmc2,

I'm checking back in — how's it going? Could you please send us a photo of your thermostat's wiring, as also requested by Patrick Caezza? This will help us identify how it was labeled so we can move forward.

We'll look forward to your response.

Regards,
