No Y or Y1 on old?

No not labeled or connected
Expert:  airheatman replied 2 months ago.

OK

On old F was fan so it will go to G

W1 should have been 1st stage heat so it will go to W

W2 should be emergency heat so it will go to X2

C was common so it will go to B

R was power so it will go to R

O is reversing valve so it will go to O

Y2 should be compressor so put it to Y
