You shouldnt have changed out the stat with a digital. Those10 yr old
Tranes work better the round Honeywell type. Get a new one. You might
need to change the low voltage wiring bundle too. The unit can get out
of phase with with a new digital stat so you need to change it back
along with the new low voltage wiring.
