Thank you for the detailed information, very helpful!! Can you do me one last favor and recommend a good replacement pump? I have a Jandy iAqualink/RS that I use for automation. It's a 20k gallon pool/spa overflow. I use liquid chlorine specifically so no salt system or anything like that.
The "teeth" on the black collar that lock it into those three tabs are what broke, so the collar is okay for now, just won't seal because there is only one of the three teeth left.
Sorry, no fix for that kind of damage. Only a replacement of the parts
might work.
What is the software revision of your iAqualink? That can be found in the "system" section of the menu. If it is O or later, the system can
directly communicate with a Jandy or Pentair VSP. Otherwise, a VSP that can use "relay" inputs can be used, like a Waterway Power Defender 270, can be used to have the Aqualink change speeds as other equipment is operated or if you have un-used relays. All that is required is getting some sprinkler wire with at least four conductors. Its available online for as little as $1150.00. Crazy to say "as little as" until you compare it to other major brands
The Pentair Whisperflo VST can also be relay controlled, but you need to purchase their communication cable as well.
If you aren't worried about/don't need complete speed control and want an easy install, the Hayward W3SP3215X20XE is a VSP that can be used with the existing relay used now and its internal programs set to speeds you desire.
Then, there is the Calimar/Blue Torrent/Black & Decker/Circupool 3hp VSP. All the same pump, but the Calimar is priced the least at about $600.00. With the addition of its automation adapter that uses relay inputs, it can be controlled by the Jandy. I have no experience with these, but there are many on this blog that love them.
