Connecting Honeywell RTH6350 to Wires

I have a Honeywell RTH6350 and would like to install it. The old tstat was wired as follows:
Blue. C
White. W2
Red. R
Green. G
Orange O
Yellow. Y
Brown. B

The new tstat has L, E, AUX, G, O/B, NOT USED, Y, R, RC

The manual states that if there is a W2 wire, and there is, to stop and call an electrician. That's where I am. I think the BLUE wire isn't connected. I'm also NOT sure where the BROWN wire goes. Can someone help me?

Yes, blue and brown wires not used. White wire lands on AUX and jumpers to E.
