I have a Jandy Aqualink RS PCB with a variable Jandy Pump. Problem is my Jandy 8227 remote is a pain in the ass. It's slow and only works 10% of the time (select function doesn't work, just scrolls through different screens). This is my second remote and don't feel like making it a 3rd. I want to upgrade to Wifi enabled phone system via iAqualink app. What do I need to purchase to make this work? I've received quotes from 700-1500, not sure why such a discrepancy, the pros are being vague on details of what's needed or I'm just not getting why it's so much. Can you guys let me know what i need to buy (which PCB circuit and wifi aqualink)? Model #s please Is this something I can or get an electrician to install or do it myself? I added a couple pictures of my current system Sorry if it's a double post, I originally put it in the wrong subsection...
