Rheem thermostat to a nest

I'm trying to convert an old rheem thermostat to a nest. Rheem wires and Connections are. :
X. Brown
W2 white
B. Blue
G. Green
R. Red
Y. Yellow

I'm confused where the x. W2 and B connect on nest.

Brown won't be used, the white wire will go on W and blue goes on C.

Rheem uses the B terminal to control the reversing valve in heat pumps (energize the reversing valve to heat).

Post the model number of the old stat.

I'd say that
brown = C
Blue = O/B
W2 = Aux
