I hooked up the Lux tx9000ts back in November and finally got it to work after hours of aggravation. Now, when I tried to switch over to AC, AC isn't working. I've checked the breaker box. I think I hooked it up wrong. (I only worried about the heat)

I have 2 wire sets coming out of the wall - one set has a red, white and green wire. The second set has a red and white wire.

I have the wires hooked up to the TX9000TS as:
W - white wire (red & white set)
Y - white wire (red, white & green set)
G - green wire
B - nothing
O - nothing
RC - red wire (red, white & green set)
RH - red wire (red & white set)
C - nothing

My original unit was Honeywell Q539A.

anyone know how this is supposed to get hooked up correctly?

Every house has heat so, I would try:

heat set
rh= heat (hot wire)
w= white (heat switch)
g= green (fan)

cool set
rc= cool (hot wire)
y= white (cool switch)

Do you have one or two LV transformers?

Post the make and model number of your outdoor unit.
If you have a heatpump, we need to find the color wire substituding for orange. We would also need a different stat, since that one does not support multistage heatpumps.

If you do not have a heatpump you may only need to remove the red(3) wire on RC and jumper RH to RC. The white(3) wire on Y should also be verified.

If you remove the panel at your furnace (or fancoil) and write down the stat wire connections there it should help us correct this problem.

"Tip of the Day" Remember to remove power first.
