I just dont know what I am doing
Did you copy the wiring pattern exactly to the new Nest mount?
Are you completely sure the wires are in the right slots on the new Nest? You might want to check the compatibility tool online to confirm. Also, make sure none of those are jumper wires.
Move the brown wire from W2 to * on the Nest. It can only handle one stage of auxiliary heat. Then set it as emergency heat in the settings.
