I am trying to replace my HPT 18-60 Janitrol thermostat with a new Honeywell RTH6300B.

Wire Diagram for HPT 18-60:

Y = Yellow
G = Green
R = Red
O = Orange
W2 = White
E = Brown
C = Black

Honeywell RTH6300B wire diagram:
C = ? (manual says do not connect)
G = Green
Y = Yellow
W = White
RC = ? (there is currently a jumper to R)
R = Red

When connecting the new RTH6300B Assumptions
JANITROL HONEYWELL
1. Green (G) Green (G)
2. Yellow (Y) Yellow (Y)
3. Red (R) Red (R)
4. Orange (O) ????
5. White (W2) White (W)???
6. Brown (E) ????
7. Black (C) ????

Question - Where do I connect the wires with question marks above?
Thank you for your help.

Your new stat is not compatible with your multistage heatpump.
The RTH7400 is compatible.

Y = yellow
G = green
O/B = orange
Aux = white
E = brown
C = black
option 170 = 7
190 = 0
240 = 9
