I recently replaced my Honeywell thermostat with nest 3rd gen learning. Turns out when i turn the heat on, the system is actually cooling.
I had followed the wiring schematics the bast i could but i assume i made a mistake. Any guidance is appreciated.

@Patrick_Caezza Thank you so much! I switched the wires like you said and heat did kick off and seems like its working. I will play around with settings some more and report again.
How was the Nest instruction and videos all off by so much?
