I have a 6 year old 22,000 gallon in-ground salt pool with all Pentair controllers, filters, pool sweeps, etc. Up until this year, everything worked well. This year, when I started it up, no matter where I set the IC40 sanitizer level with the Intellitouch panel controls, the level lights on the IC40 generator show 60%. All other lights are green. The pool water sample I took to have analyzed show proper levels of everything. What does this mean? I don't know if the generator is actually running at 60%, or at the level I have set on the controller. I have tried running at 20%, and then at 80%, and regardless, the lights show it is running at 60%. I would appreciate any help here.
