My Hayward Aquatrol is not producing chlorine, its only 2 years old, there are no red lights flashing or on at all. It says that it is generating, when I press the diag button I see that its getting juice. I don't remember the numbers off hand but its something like 3.23.
The pool is at 71ish degrees.
The only thing that is different from last season is I installed a light in the return and because of this the tube is not a full 90 degrees. Its at a slight angle. I have cranked the dial to 80 and its still showing less than 1 when I test for chlorine.
