Nest Learning thermostat 4 wiring issue

[Bk911rsa]

We have a dual fuel Trane heat pump with a propane back up and the system isn't working since install.  Right now I get no heat.  The HP won't turn on, nor will the furnace.  I've added the picture of the old thermostat and a picture of what Google says it should be.

Thanks for the help.

Looks like I got it figured out.

This is how you should wire the Nest.

Black - Y2 to Y2

White - W1 to W2/AUX (set as AUX heat) (Jumper to X2 not needed

Blue - S1 - tape off

Brown - S2 - tape off

Green - G to G

Yellow - Y to Y1

Orange - O to O/B

Red - RC to Rc (jumper to R not needed)
