I recently installed a new LUX TX9100E thermostat. I had no problems when the a/c was on but now that I turned on the furnace, I get nothing but cold air. I want to confirm I have the thermostat hooked up correctly before I call out a technician.

The thing that is throwing me is the original thermostat did not have the blue and white wire hooked to anything. Also I can't tell if the furnace is one or two stage or if has a heat pump. I have tried to find the model number or service manual but there is nothing on the furnace. Please take a look at the attached pictures and ask many any questions you can think of.

I can't view your pics. You can post them directly here but may have to temporarily allow posted scripts.

You can also post the stat = wire combination of your old stat and your new stat.

I just want to confirm that there is a 99% chance that you do not have the tstat hooked up correctly hopefully we have not burned up the control board or anything yet. Pictures are still not working either. Just go to the AHU and list the color of wires being tied to what color of the tstat wires and then go to the tstat and list which color wires you have on which tstat terminations, the pics may not be neccassary anyway but would be nice.
