I'm glad you you found what you needed. The HWH site does have everything but it can be a chore to negotiate. I talked to one of their technicians who explained how to find some things. The good news is the info is available as are the parts you might need.
I bought my system used and it came as a box of parts, wires and hoses. With the help on the site I got it installed and working. If there is anything I can do to help don't hesitate to ask.
