Trane Heat Pump tstat replacement with Honeywell prog - wiring question
 
I want to replace my Trane Weathertron tstat with a Honeywell RTH7400 prog one. I have a Trane heat pump with aux heat. I've been poring over these thread piece-mealing some info the follow is the result.

The old wiring scheme:
X2 - black
O - orange
G - green
Y - yellow
T - tan/brown
R - red
W - white
U - n/a
F - n/a
B - Blue

The honeywell has the following options along with my current wiring in () as see on this forum.
C - (blue)
G - (green)
Y - (yellow)
O/B - (orange)
RC - jumper with R
R - red
AUX - white
E - tan
L - black

Results:
Power runs to the tstat and fan blows on command in manual temp mode but the heat doesn't seem to be produced.

Can anyone cofirm the correct wiring above ?

Thanks in advance,
