Trane heat pump Tstat and reversing valve
 
I have a Trane TCON900 programmable Tstat....

Downloaded the manual to try to find where the outdoor air cutout temp could be adjusted. I have heat pumps with gas back-up. Manual mentions this feature but doesn't tell you the code number or how to adjust it.

Also, 1.5 ton unit compressor just started "rattling" for lack of a better word....seems to be affecting performance but I haven't checked any temps. I just switched it to emerg. heat and am operating on the furnace right now. Thoughts?

installers guide

page 10

Option 345 should be set to 2
option 350 is the balance point.

I would call a pro to check out the noise/compressor operation......
