Nest Thermostat Cooling in Heat Mode (No heat pump)

[ksylvester]

Basically the title. It's a new install, I've triple checked the system is compatible. I have a conventional gas furnace. When I turned my system in after install, it shows that it's heating the house to 71F but the registers are blowing cool air.

Please help this chilly OP

I can't! I took a photo in the app and it deleted it during setup

Post a picture of the original thermostat's wiring here?

Can you take a picture of the terminal block on the control board in the furnace/air handler?
