    Intelliflo RS-485 disconnected but still "DISPLAY Not Active"

    I want to see the settings on my Pentair Intelliflo VSF (it is connected to an Aqualink RS & iAqualink controller) but the display on the pump says "DISPLAY Not Active!" I've tried temporarily disconnecting the RS-485 but it still says "DISPLAY Not Active!" None of the buttons does anything...

    Time to replace Hayward T-Cell-9?

    My Hayward/AquaRite T-Cell-9 appears to be failing (it's about 6.5 years old) and I'd like a second opinion. Readings on salt have been all over for the last week or 2 (from 700 to 2800 with instant between 0 and 3100, store test showed 2800). It appears to work with sane readings (including...

A couple years back (June 2016) I replaced the thermistor on my board and it was totally split in 2. I just went out and removed the cover and the thermistor looks ok -...

    New Jandy/Zodiac Spa Side Remote w/ Aqualink RS4 - button 3 not working

    I just bought a new Jandy/Zodiac spa side remote switch (4 button 7443) to replace the old one that failed years ago (sun deterioration followed by a short, presumably). Before fishing the line through, I connected the terminal (wired the same as the existing one) and plugged in to my...
