My old Swim Pure Plus green GLX board died and I replaced it with a new blue GLX-PCB-RITE board with the 1.59 software revision. Do I need to calibrate it for my T15 even though it is set to that size cell by default? Despite replacing the board, we've had to manually add liquid chlorine as the pool has started to green up after the replacement. When the board died, the relay leg burned through the board and the trace that burned through connects to the plug for the salt cell. Is it possible that it took the cell out too? Is there any good way to check? I took it to Leslies for a test and they said it needed to be replaced, but I'm wary of my local store. The cell is about 5 or 6 years old and was working fine before the board went out.
