New installation by owner, Gen 3 learning thermostat, furnace does not come on

[Buds]

Old thermostat had black wire from RHTo RRC but I did not install because directions said not to. Furnace will not run. Any suggestions will be appreciated.

Hi Buds,

Thanks for reaching out. I'd love to know more about this. Could you share a photo of your current thermostat's wiring? Also, you could try our compatibility checker to see if your current system is compatible with the Nest Thermostat.

Thanks,
Mel
