1221,
Looking at your pic above...
The raised valve on the left is your "Return" valve.. It selects either Pool or Spa, currently in the Pool mode
The first valve to the right of the Return valve, I suspect is the valve that controls the amount of spillover your spa has when in the Pool mode..
The next valve to the right is labeled Cleaner..
The valve on the far right is your normal wall pool returns.
It does not look like you can shut the wall returns off.. But with all the water going to your spa spillover, your cleaner, and your returns, I am not sure there is enough water to run everything at the same time.. (Kind of why I asked about your filter..)
Is your water clear, cloudy or green??
As a quick test, shut off the valve second valve from the left (Spillover) and see how well your wall returns work with the cleaner off.. Then open the cleaner valve, and see how well the wall returns work with the cleaner on.
Let us know what you find.
Thanks,
Jim R.
