I have a Trane Tcont802as32daa touch screen Tstat. It is the same as my honeywell Th8320(pro 8000). My problem is that Trane uses terminals R, Rc,O,Y,G, B, / Y2,F, X2,W1,S1,S2.
My qustion is that there is no C for common. which terminal does Trane use for common?
Also, what do they use F and X2 for?
Thanks for any help,
