I connected with Josh from the saltpoolguys.com site, where I purchased the new cell and tri sensor, concerning the new message I am getting.

After some additional troubleshooting and sharing some pictures of my controller, it appears I have a bad board, specifically 4 of the 6 capacitors are shot and it appears one of the computer chips may have overheated as well.

The board alone is $400+ and the whole controller unit is 600+ and comes with a new cell cable and a two year warranty so I elected to do the whole unit. Awaiting arrival of the unit, should be here Monday, Tuesday at the latest.

At that point I will essentially have a new system and just need to get it back operational. Now if I can just keep the pool stable until I can get this installed the grandbaby can get back in the swim mode.
