Wiring a Honeywell CT3611R Thermostat

I am attempting to replace my SECO TA2000 thermostat with a Honeywell CT3611R. On the old thermostat I have the following wiring/terminals:
B (Black), W2 (White), O (Orange), X (Blue), R (Red), Y (Yellow), G (Green), E (Tan).

The new thermonstat has the follwoing terminals:
B, L, C (on the upper row), R, W2, E, W1, Y, O, G. I've attached the W2, O, R, Y, G and E to the cooresponding terminals. The instructions say to attach the X wire to the C terminal, but not to attach wires to both the B and O terminals. So where does the B wire attach to?

Thanks for any assistance.

You dont say just what you have here???? But with E O and B, I take it it is a heat pump.Find the wire schermatic for your unit.See what colors are what.
On the CT3611
C - common
R - power
Y - compressor
W1 stage 1 heating relay
W2 auxiliary heat relay
G - fan relay
O - cooling change over relay This is the two you have to
B- heating change over relay you have to check out
L - system monitor
E - Emergency heat relay
You can only use one O or B. find out what you have here first. just what is O and B wires
Also didnt it say jumper Y to W1 keep it on
