Hello automation members! I'll do my best to explain whats happening. I'm a novice at best with electricity just enough to keep from getting shocked. Opened this year equipment is 3 years old. All Jandy equipment. My JVAs connected to my subpanel are not working properly all seem to have the same issue however when I opened one of them it did smell as if it was burnt but can't be sure on that. First thing I found was the fuse in the subpanel was blown I replace it and began pulling the connection to each JVA and I did find that the smelly JVA did blow the fuse how ever when I replace it and left that connection diconnected the other JVAs still did not fuction. Thats a bit confusing because if the one blew the fuse why would the others not work? Theres only three JVA hooked to the subpanel. I've included photos for more deatil and maybe help with my issue. I have three pumps filter, and two for the spa, the spa bumps have dual purposes thats where the JVAs come into play I have a slide, a shallow fountain and two deep end fountains. The three JVA on the subpanel direct the water to the features using the app. Everything worked when I closed last year. Any help would be greatly appriciated! The photos provide the main and subpanels.
