Got it working! ...
Ditto: I know your thread was originally about comparing GHL to Neptune but I see others have gone off in tangents. I have a very complex ATO system with layers of redundancy and will need help with Programmable Logic. Do you mind if I post the question here or do you prefer I go to another thread? (I plan to spend several hours today working on as much of this as I can and organizing the question).
I'd recommend starting another post in the GHL thread so that other people who may have a similar issue can find it more easily.
