How do I connect the wires from a Janitrol to the Honeywell RTH7500 Thermostat. I have the following wires:

R Red
Y Yellow
G Green
O Orange
W2 White
E Beige/Pink
C Blue
Black wire not connected

I connected it to the Honeywell as follows:

Red to R which has a jumper to RC
Yellow to Y
Green to G
Orange to O/B
White to W2/Aux
Beige/Pink to E/Y2
Blue to C
Black not connected

It is not working, the unit will not turn on for A/C or Heat

Check to se if you have 24 volts at the thermostat. During wiring you might have caused a fuse on the board to blow.
