Hayward Swim Pure Plus circuit board/display board

[furshore]

I recently had my T9 cell replaced under warranty. I had unusual readings such as temp 110 (actually 65) salt 2400 pool store tested at 3900. The version is 1.50. I have installed my old circuit board and old display board and have closer to correct readings. The temp is 65 and the salt is 3100. It is an older board I believe 1.40. It seems to be generating and working properly. Is my newer 1.50 circuit board bad or is it the old display board? Should I just keep using the old board or do you have a better suggestion.

Welcome to TFP.

I recently had my T9 cell replaced under warranty. I had unusual readings such as temp 110 (actually 65) salt 2400 pool store tested at 3900. The version is 1.50. I have installed my old circuit board and old display board and have closer to correct readings. The temp is 65 and the salt is 3100. It is an older board I believe 1.40. It seems to be generating and working properly. Is my newer 1.50 circuit board bad or is it the old display board? Should I just keep using the old board or do you have a better suggestion.

It is confusing what combination of parts does not work for you and what the symptoms are.
