I just posted my intro post- summary is that I'm a newbie to pools and I just purchased a house with a pool that has a lot of needed maintenance. I'm guessing the Aqualink system was installed years ago (judging by the faded paint).
I have 3-way valves with JVA's installed in what I think is a pretty standard way - on my main intake and return, so that I can turn on my spa. When I moved in, neither did anything when I changed to spa mode. The intake JVA would turn if I manually flipped the switch, so I ordered a replacement JVA and installed on the return. Except the switch would make anything work.
After resetting the aqualink, trying Auto and Service modes, checking the 3amp fuse, trying through the phone app, I finally pulled out my voltmeter. I looked up the specs, and the black wire was common, and the other two are 24VAC depending on direction. However, at the panel, my intake JVA port was reading ~16VAC on one leg and would only read 0 on the other leg. The return JVA would only show 0 (or floating) on either leg, for any mode. I can hear the relays click as I change modes, but the voltages never show 24VAC on any of the legs.
I finally decided to try one of the two unused JVA ports (cleaner and solar). I focused on the cleaner one, and was able to test it and confirm it works as expected. So I plugged in the intake JVA into it, and pushed the cleaner button, and the JVA worked as expected in both directions. Same when I plugged in the return JVA.
So... my guess is that I have two bad relays on the board, but I'm open to other suggestions (and options). I seriously doubt that replacing relays is a good option here... what else can I look at?
