    New AQR T-9 install problem

    Installed new AQR T-9 today and all is well except that unable to select type of cell and no Lcd display. Tried to set switch to auto press diagnostic button repeatedly and no response. Also top four lights are blinking green, next three also blinking red, last one blinking amber. Have tried everything in manual. No go. I must be missing something. What is it?
    Configuration is: Cell after filter with hump down flat followed by flow sensor with nut upright flat position next is return line.
    Quick question: Since one is supposed to select cell type first which I have not been able to do, I am assuming that cable to cell should not be connected. Is this correct? How bout cable to Flow sensor?
    I have confused myself, any and all tips appreciated. Thanks. Jim
    PS Tried both ways, made no difference.

    You should go ahead and connect both the cell and the flow sensor. Just leave the percentage setting at zero. I believe that will allow you to get into the diagnostics display and set the cell type.

    Thanks for the tip. After looking inside box, removed cover panel, noticed that pc board holding lcd was not secure, then noticed that of 7 pins that should have been inserted into lower center of same only 6 pins were properly attached, corrected and system came alive. Also used your procedure and selected proper cell. Seems to be working properly now, will let it run and see what happens. I think lcd display is not 100% as it is not showing letters clearly. Otherwise, Ok.
    Spoke with Hayward Tec. support guy and his thoughts were bad board and suggested calling local PP service which I did and made appointment for inspection. Now not sure if I should cancel or not. I think it over w/e as appointment is for tue pm.
