New homeowner. I can't for the life of me figure this out. The other day when I turned my jandy PDA to spa mode, the spa continued to overflow into the pool. I found my control valves and tried fiddling with the switches to no avail. They operate one direction or the other by flipping the switch....as long as the pump isn't actively running. I also think I have determined the bottom is my drain valve and the upper is the return. In the current mode showed in the picture, this returns water to the spa as well as the pool and seems to me my functional pool mode. When I hit spa mode, the upper valve rotates 180 clockwise and the bottom remains stationary. If I move the bottom 180 in the other direction, it seems to drain the spa. What am I missing?
