You have a Heat Pump system with auxiliary heat. What model of Nest Thermostat did you acquire?

Ok, so here is the wiring for your Nest Learning Thermostat.

Red Wire, Nest Rc

White Wire, Nest W2/Aux

Blue Wire, Nest OB

Yellow Wire, Nest Y1

Green Wire, Nest G

Brown Wire, Nest C.

Set your system Equipment as Heat Pump, Type O, Forced Air.  The will automatically detect the W2 wire will assign it to Auxiliary Heat.
