Jandy Aqualink not starting up for season

[pgershon]

Old Jandy system - originally installed in 2000. Was upgraded to iAqualink (first version) and board was swapped at the time. Two touch keypads, both not displaying (se photo attached). I hear the system controlling my pump, but I cannot access the programming without the keypads (and iAqualink says my system is offline). Any troubleshooting ideas?

Breaker was off for winter - just turned on today and displays came up broken. I tried resetting the Jandy at the main board but Keypads still blank. I also tried removing one keypad but it did not help either. I guess next steps will be to disconnect all equipment then add devices back one by one.

Need to run pump 24/7 while I SLAM pool (it gets green in March - no winter cover) so not urgent problem, but it would be nice if I could diagnose the issue as something other than "needs new board". I had to replace the keypad once about 15 years ago - pool repair people said at time likely result of power surge.

The firmware message shows your keypads have power and the display is working. It looks like your keypads are not communicating with the panel.

And you say your iAqualink is offline.

So I think you have a problem with your RS-485 connection the keypads and Aqualink use.

I would open your panel and check the wires. Disconnect the keypads and see if you can get iAqualink connected. Connect one of the three devices at a time to the panel.

is your Pentair VS pump controlled by RS-485?

Thanks. I got it going after only about three hours of misery. Two different wiring issues found. One of the four sockets on a multiplex board was bad (in crawl space under pool house). Also, i had disconnected my variable speed spa pump for winter and not yet reconnected. Two of the wires from pump were touching. That was fetal…
