Replacing tstat

My unit is a Janitrol heat pump M# AWB24-10D, 9 years old. I have 8 wires: green, brown, blue, yellow, white, black, red, orange. The brown was never hooked to anything.
My old stat is a Simple Comfort 2200. It has these outlets: B,O,W2,G,E,Y1,Y2. These are in line across. Then there are 3 that are in a line going up with J2 to the left of the bottom one, and the letters S,L,R on the right side of it. The wires were plugged in as follows:
Red J2
Orange O
Black W2 and E
Green G
White E
Yellow Y1
The Y2 and B were blank. The blue wire was in the top left outlet of the line of 3 going perpendicular.
My new stat is a Honeywell TH6110D1021. .
I was able to hook a stat just like this one up to my boiler and it works great. I only use the heat pump for A/C, but all I keep getting is heat. It has outlets G,W,C,Y,R and Rc on top. It has O/B under it. The R and Rc are jumped with a wire. It came that way. I currently have it hooked up as follows:
Green G
Blank W
C I have tried the blue, then the black, here but keep getting heat instead of cool air.
Yellow Y
Red R
Orange O/B

What do I do now? I can’t tell which wires go to what part of the unit.

You need to identify the blue wire from the other end. You can't guess at it.

For the most part your wiring is right. Have you programmed the stat for your particular system ?

1 ---- 1
2 ---- 0 (reversing valve powered in cool mode)
3 ---- 1
5 ---- 9 (for now)
9 ---- 3
12 --- 0

Page 10 of the manual explains it further.

Your new thermostat is not compatible with multistage heat pumps.
Aux and E would be additional stages of heat.

The 11 in the middle of the model number indicates the stat is 1 heat and 1 cool.

Does this thermostat control electric heat strips?
What is Aux heat and Emergency heat controlling.
