Aqualink not recognizing Aquarite

[HackerPool]

I just replaced the controller board on my Aqualink (old controller board was J and had issues with my spa-side switch, replacement is MM and runs the switch correctly). After the swap, the Aqualink does not seem to recognize the Aquarite and the Aquarite "remotely controlled" LED is not lit. I connected the RS485 and even tried a new wire - no difference. I also tried setting the Aquarite to AL-5 and power cycling, still does not recognize it.

Thanks

Update: after contacting Zodiac/Jandy, I've been told revision L or newer is not compatible with an Aquarite and I'd need to either disconnect (warning about frying the PCB) or downgrade back to revision J (I,J,K were supposedly compatible).

I saw mention of setting the Aquarite to AL-5 to emulate an Aquapure, but that did not work for me, possibly because I tried it after first trying the default of AL-0.

Hacker, I'm glad you got all 4 buttons working on the spa side switch!

My inclination on your original post was that the new problem was a rev issue, but I have no experience with the Aquarite. I'm curious about your next steps.

Hey Dodger - for now I plan to live with manual control of my Aquarite until I find a rev I, J or K Aqualink replacement board. L or newer appears to be a no-go for an Aquarite SWG.

Ebay seems to have some of i, j and k.

Closing the thread - I was able to get a JJ chip and install it on the board. All working, Aquarite, spa switch, indoor controller.

This information has just come to me. At first it was thought that Jandy started locking out SWGs with Rev T. Well, on the 52 pin chip, they did it for Rev M, MM, and MMM.
