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.
