Air Conditioning - Thermostat Problem

Hello,

maybe someone can help me. I have an older Heil split system A/C heat pump.

Tried to install new thermostat from an old manual (mercury) to a digital. I can't get the A/C to come on.

I went to the attic and found these wires connected to the air handler.

Red to R
Blue to C
Yellow to Y
Green to G
Orange to O
White to W1 and W2 (jumped)

I took a picture of the previous thermostat wiring so I would remember how it was hooked up. PROBLEM picture was deleted now I am unsure. All of the above wires were in use at the thermostat the white wire at the thermostat was stripped in two places and connected to two terminals.

there is a optional jumper on the new Honeywell digital thermostat between Y and W1.

I think it is the white wire that is giving me problems.

I have hooked up the following
red to R
Blue to C
Green to G
Yellow to Y
Orange to O

beyond this I am unsure........jumper or no jumper? White Wire where? :D

Did you turn off power to both air handler and outside unit before you changed the stat?

Is there not a W or W1 on the new stat?
