Question for those in the know-
The control panel for my IC40 displays the percentage in 20% chunks. My automation system allows adjustments by single digits. I have been hesitant to run the system at anything but 20% or 40% as it shows on the unit.
The problem is that at 40% I get too much chlorine and at 20% too little. Could I set it at 30% and would the IC40 produce it at that rate?
