1st, Never have your secretary do this for you. My pool is 16x32... 3'to 8' depth. Just had this Hayward Aqua Rite Generator with a T-9 Cell installed and the installer doesn't even know how to read the LCD display. My display never has read as it was supposed to do as per the instructions. 1st t-9 never came up to set the Cell type, I got something like a E-3,5,9,15..I assumed this was close and chose the 9.... F, never came up to set it to Fahrenheit, so when 28 came up, I figured it was Celsius..Was right. and set it. This is what comes up and in order that it comes up. It shows what the control knob is set on 1st. I push the Diag. button.

Some of these bottom numbers change, as expected, if left alone. It seems to me if you Posted the proper sequence, I have something is wrong . I hate not knowing how things properly work. It appears that the 3900 which seems to never change is the only thing that matters and I am still going to the Pool supplier every week, Just not buying anything, Which is GREAT....
