Another oldie but goodie valve question

Oh, wait... Was that first chart something you made or something that was in the manual for the system?

was that your description of operation in the side note? I thought all of that was put of the manual

I don't have a manual for the system. The first chart I made. I was trying to understand the overall system and all the parts, manufacturers, etc.
The 2 chart is just the water flow. Much simpler.

Ahh.. ok. I would wait for the others to chime in but I do think you are on the correct path. The way it is now just makes no sense. Seems to me when the handle is currently in the horizontal position that would be correct for the solar being on. Then the actuator should rotate it 180 degrees to close the solar port.
