problem with thermostat wiring?

Question

I had an HVAC man come and install a honeywell th6220d thermostat for me. When he wired it he strapped the aux terminal to the emergency heat terminal. there is a note in the installation manual that says to do this if there is no emergency heat relay. I have a trane heat pump and i am not sure if it does or does not have this. My bill has doubled since this was installed. I was wondering if this strap should be here or not.

Answer 1

Check your other post. You have some good answers there.

Answer 2

1. That will bring on the AUX heat all the time. So the jump wire is not needed.

2. The thermostat has whats called a installer menu. That is how program the stat for the type of system you have. If its not set correctly pray when you get the bill. It should be set up 2stage Heat/ 1 stage Cool



Lastly, I had one of those stats. I hated it. I was on the phone with Honeywell stating that its not reaching set points correctly and is constatly bringing on aux heat. There answer its working as pre-design. My **** just like you mine more than double. I took that POS back and got a white rodgers stat. My bill dropped 150 bucks. Yeah..... That stat is a "universal stat" it will work, however, it not really a designated heat pump stat.



Here the whole manual included the hidden menu that the HVAC guy would be messing with to setup Under the settings it should be like this: (you can check this very easy and change if needed)

Also on the AUX heat setting if you lower the CPH to say 2 the aux heat wont come on as much.

System Function / Settings-options

1-5

2-0

5-9

6-9

10-3

12- User preference for auto change over 0 is manual 1 is automatic (dont change it to 2 )

13-1

14- leave at default setting

15-5

16- you choose 0 5/2 (programmable weekdays and weekends) 1 5/1/1 (weekdays, Sat & Sun prog)

27 leave this alone

28 leave this alone

Answer 3

He definitely has the aux heat running. I would call the company that did it and have them send a new tech out to fix it. The wiring does get complicated if you don't normally deal with diagrams.

Answer 4

You are heating Your house with the emergency heat system that's why the bill has doubled. follow instructions for you heat pump on how to hook up the t-stat. or call tech to come back and fix it. good luck.

Answer 5

Have to HVAC man back out to fix the problem. If it is a reputable company they should do this for free.

Answer 6

go to the trane website and find out if it has this but if your bill doubled i would bet that it does.
