Installed the SI45+ system last summer and have had no issues until recently. The default reading on the panel is the salinity reading. Usually the reading is in the 2900-3400 range, which is where my system seems to run best. The current reading is 3.6. I have toggled the super chlor switch back and forth thinking I be switched over to grams per liter. Nothing changes. I am also unable to get any type of instant salinity reading when i toggle through the menu on the LED. When I push the button 1 time and go to the temperature setting screen I am unable to change the setting from Fahrenheit to Celcius by toggling the super chlor switch. The system is still generating chlorine, and I just completed a cell cleaning today, thinking that might be the issue. Any suggestions?
