Do I have to assign this to a support specialist, or does someone usually respond? Thanks in advance

Is there anyone out there???

Hey D2theIzzo, 

Sorry for the delay but thanks for posting and for the photo. 

It is best that you contact a local pro for assistance as you have both an O wire and a B wire. Sometimes, the common wire in some systems are disguised as a B wire but we need to be sure. Check this out for more information: https://bit.ly/3zWUw1G

hi Melba. I was able to get this to work after researching our current 7-wire system and configuring as follows: 

R to Rc

W2/X2 to W2 Aux

W1 to W1

Y to Y

G to G

O to O/B

B to C

this worked for our system and passed all tests. Thanks for the assistance.
