I'm in the process of moving into a new place and wanted to replace the old cruddy thermostat. I figured it would be no big deal and bought a Trane Remote Energy Management Thermostat **://-.amazon.com/Trane-Remote-Energy-Management-Thermostat/dp/-***-*. I took apart the old thermostat and followed the instructions in the PDF for setting up a heat pump. **://-.smarthomeusa.com/Products/TZEMT043AB32MAA/manuals/TZEMT043AB32MAAInst.-***-* While wiring the new system (step 11 in the PDF) I noticed that I did not have an existing "W" or "W1" wire. I was also confused as to why "Y" was listed in the "w1" slot and in the "Y" slot, so I bridged them together with a wire. I also had an issue with the "RC" wire on my old thermostat. (see pic below). The wire that I assume is RC first goes to "4" and then bridges over to "RC". Needless to say I have not been able to successfully hook up my thermostat and the only thing I get is blower with no heat. I wanted to see if I could find help here before I had to hire a professional to hook up a darn thermostat. I've called the tech support and they only tell me that I need a pro to come out if I do not have a dedicated "W1" wire. But considering the old mechanical thermostat could handle not having one, I do not see how it is possible that the newer better thermostat cannot handle it. There has got to be something I can bridge to make this work? Or do I really need to run another wire through my house to hook this up. Below is as much pertinent information as I could think of. Thanks to anyone who might be able to help.
Gibson Heat pump with 1 Zone
Y(blue), G(green), W(white), RC or 4 depending how you think about it (Red)
24Com, 24RC, 24RH, W1, W2/O, G, Y1, Y2
I've attempted to bridge Y and W1, Y and W1 as well as Y and 24RC, Y and W1 as well as Y and 24Com. The only thing that I ever get is blower with no heat.
