Of course, I did not do that.... I am a homeowner making repairs -
it was working previously, salt was normal, and the sensor went bad with a low-flow reading - I had it replaced once before so had been through the drill. this time, I purchased a sensor, but the snag was it came with adpater board, which I could not install without an interface cable. Back to Ebay... All said and done and connected, it did not work and was giving a NO FLOW indication, eventhough the adapter board's Flow LED was illuminated. double checked firmware level, jumper, reset, calibration - hmmmmm, still having problems. put it on SPA with 0% chlorine set and it stopped reporting any problems, and I had a soak while contemplating next moves
It came on the next morning as usual, but with a HIGH SALT indication, so I let it run, while I posted my question - I checked it a few times and utlimately found the error is cleared, Salt is at 3900ppm and it APPEARS to be working- I'll run out and check the chlorine so I can establish a base line and see if it is really producing.
I was thinking I needed to calibrate something else, but it appears overtime, it took care of itself. still a little gun-shy
My PLC1400 is getting on in years - about 6 now - and I am considering replacing - Should I just drop in a new one or should I go with something else - this is the third sensor so am not in love with the Jandy brand, but all in all, it has performed pretty well? I hope the new adapter board and black epoxy sensor is an improvement.
