Aqua Rite Chlorine Generator - NO T CELL INFO

I have an Aqua Rite Chlorine Generator that would not show the T Cell Size (It show s “0”).  The PC board is GLX-PCB-DSP revision 1.33.  The T Cell is a Blue Waters BLT15-3 W, which it’s also confusing, because I don’t know if it’s size 3 or 15.  Any help will be greatly appreciated.

Most aftermarket replacement cells require software version 1.5 or later on the AquaRite to operate properly.  Your mainboard and software version are probably not compatible with the Blue Waters cell if it reads that it is version 1.33.
