Tstat upgrade confusion

I am replacing my old Trane-Weathertron tstat with a Hunter Touchscreen Tstat. I have matched most of the wire to the correct terminals but I have run into a snag. On the weathertron there was a R terminal and a T terminal, but on the Hunter there is none. Also I do not know if I have a two stage or three stage or whatever. Can anyone help me? Thank you!

Tstat upgrade confusion

Not familiar with Weathertron stat. Possible that is a common term? Find where the other end of the wire terminates on your control board, that should help. Also have not seen good luck with those Hunter t-stats, nothing available from Honeywell?

T is for the outdoor anticipator.
Your Hunter doesn't ned that.

Your HP should be single stage with aux heat.

If you list teh terminal designations of teh Hunter, we might be able to tell you what they are using as the R terminal.
