When I turn my heat on, my central air unit turns on and has cold air coming out

[Markbovenzi]

Hi there! 

Hopefully this is an easy question. I haven't changed any wiring in my nest. Everything was working fine until I had to factory reset the unit this evening due to a Google Home / WiFi issue. When setting it back up, I think I did it incorrectly, as when I turn the heat on, my central air unit turns on too and shoots out cold air. 

I've attached a picture of my setup and how I have it setup in the app. I definitely did something wrong haha. But it's gas heat, forced air. I also have a two stage furnace.

I was able to figure it out. I omitted the Blue (O/B) Wire on setup and just checked Y/Y1, C, W/W1, G/G1, R and that worked. 🤷
