As a follow-up I completed my upgrade from ST-2D to the NCM-3Z control board. The swap over was relatively easy and as described in this post.

Re: Swapping out an ST series zone control to model NCM-3z zone control
I also ordered a NCM-300, but received a NCM-3Z controller. I do not see a response to your post, but after reviewing the following documents, I am aligned with your conclusions and wiring diagram. Did this work for you? Can someone from EWC confirm before I perform this swap on my system?
