Just finished up our backyard a few months ago. Thanks to solar and some great weather here in northern CA, we've been enjoying it since mid april. The water looks and feels great. I have a decent test kit (not strips) and all numbers are within the recommended ranges. I've also had the CYA and CH tested at the local, independent store and all is good.
The basic equipment is nature 2 soft with zodiac/jandy PDA. I've done several salt tests (incl at the store twice and all show around 3600ppm (the PDA says 3800)
I noticed that everything is running fine until the water hits 84 degrees. Then - if the solar is on - the system beeps and PDA reads General Fault/High Salt/4100ppm.
However, when I turn the solar off, the error goes away regardless of water temp. and the PDA and box shows everything working fine.
Any help would be greatly appreciated.
