Was the compressor clutch engaged or cycling at all?

I don't understand what you mean by the water valve worked exactly opposite depending on Max or Norm. It should only be open or closed. Do you mean it would open on one setting, then close when you switched to the other setting? Or do you mean it starts in some intermediate point, goes fully clockwise in one setting and fully counterclockwise in the other? Assuming the former, does the temp setting function completely opposite between Max and Norm?
