Trane heat pump wiring


I don't think that I would disable stage 2 heat, but it would lower the electric bill.

Honeywell makes some reliable stats. The RTH7500 and the RTH7600 will support your multistage heatpump (Even though I posted the conventional diagram)

That sounds good. I will look into one of those stats. There is a brown wire on my defrost board and the guy that was helping me told me that he believed it was for the emergency heat when the system goes into defrost. Should I hook it up to my emergency heat line? It is brown and labeled T1 on the defrost board. I tell ya what I spent weeks online trying to figure this all out and with your help I have spent very little time. Thanks again!

Honeywell will not support that Thermister terminal. Do not use it.

Awesome! I am getting a 19 degree temp drop on ac and 25 degree rise on heat mode. Is this right? I am unclear on how to charge the unit properly so I charged it in ac mode as if it were a air conditioner. I measured the temp going into the air handler and the temp coming out the nearest vent.

Your diagram is good.

People that want to be able to raise the set temp without the aux coming on.
When the temp is above BP. Need to alter the wiring though.

He may want to use a stat with an outside temp sensor, that can lock out aux.

Trane heat pump wiring


Thanks again for everyones help. Well really Houston gave me all the help. Everything he said to do was dead on the money. My heat pump system has been running perfectly for over a week now. Does anyone have any idea how much they think it will cost me to run ? I live in a single wide mobile home built in 1975 and the furnace I pulled out was the original Coleman. I did away with it to get rid of gas as I dont have anything else gas. They charge me year round even if i cancel service for a few months so I didnt want to mess with gas anymore. I bet my gas bills were 300 a month last winter and my electric was around 200. I believe the old furnace was killing me on the elctric side with the 110 motor as I had it removed and my bills went from 160 to 60 when I wasnt using the heat/ac. Anyways I believe it will save me several hundred dollars a month with this new set up. Im excited.

You are welcome .
Wow, that is a very high gas bill. My gas bill is $60 in the winter and $30 in the summer. I use an 80% furnace.
