    Factory installed Oxygenator question

    I'm hoping someone with factory installed Oxygenators can tell me how they are wired to turn on? I have a 2020 CX20 and noticed the Oxygenators did not come on when filled with water. I pressed the first accessory button and it turned on the starboard Oxygenator, but not the port side. The second and third accessory appeared to do nothing. Should they both come on with the first button or are they turned on separately?

    I need to check mine. I have never paid attention. I just assumed mine came on in conjunction with live well recirculating. I’ll check mine out this weekend.

    Thank you, I thought that would probably the same with mine. My problem may be a bad connection or bad Oxygenator.

    Acc1: live well oxygen

    I found my issue, both are connected to the acc 1 switch. I had a bad Oxygenator, replaced it and now good to go.
