Unless I’m missing something, I think this is easily provable: 1. Confirm that there is CYA in the pool 2. Test the FC level 3. Dump a known amount of chlorine in the pool and circulate. Confirm via PoolMath the amount of FC added based on pool volume and chlorine bottle specs. 4. Test the FC...

Final update on this saga: I ended up buying a new IC-40. Amazon price: $1,249 plus $100 tax; no thank you. Our friends at Marina have them on sale, $999, no tax over the phone: https://marinapoolspaandpatio.com/product/pentair-520555-intellichlor-ic40-salt-chlorine-generator-cell I took my...

What type of pump do you have?

Eeks, another update: So I thought the chlorinator was working again. I went out a couple days later to check and it was in an endless reboot loop. It’d go through its startup steps, flash the lights per routine, and then as soon as salt flashed green, it’s shut down for a second and restart...

I am not sure if the below qualifies as a math model or empirical, but it uses real world measured data from my system across three different scenarios, using the two speeds I use on my IntelliFlo VSF (24 and 65 GPM). In each of the scenarios, the mix of low and high speed is demonstrably...

Well, this is embarrassing… Gave the male pins on the plug a scrape or three with a T7 star bit and… it’s alive!! Thanks for all of the help, I will accept all of your insults now!

Quick update: I called Pentair and they said the range is 22-39 VDC. Will be curious when I check it later tonight whether the voltage drops when I plug the cell back in.

Hmm I have the cell disconnected currently, maybe tomorrow after work I can check it with it plugged in. Was also thinking about stopping by the dealer’s sales/service shop and seeing if they can test the cell. Will definitely report back voltage with it plugged in when I can. Thanks again!

That’s right, no separate power center if you have an IntelliCenter that was packaged with the IntelliChlor guts inside of it.

Ok @Jimrahbe, looks like, after moving everything out of the way, that I have an LED lit green on my surge board. 30V AC, 26V DC. DC seems low right? Pics below for posterity, including of my transformer, which has got a bunch of oil all over it.

I saw a video with a fuse in a power center but I don’t see a fuse anywhere in the IntelliCenter (I think it has a breaker, which doesn’t appear tripped).

Super helpful, thank you! For what it’s worth, I can hear a click in the panel when I switch on pool mode; I always assumed that’s power hitting the salt transformer, and if so, it appears that at the very least that side of circuit still works. My IntelliCenter has a bunch of wires and boards...

Thanks, Jim. The picture you posted was what I was using for comparison earlier. When I get home later I will try to pull out the voltmeter. Can I test the board with the salt cell disconnected (it’s already in my trunk, as I was going to see if the builder’s shop may be able to test it)...

Morning! I saw this morning that my IntelliChlor IC-40 had no lights on. I looked in my detected equipment screen on the IntelliCenter and it said not connected. I found the linked thread below and took the top panel off of the IntelliCenter to see the surge board, and I can’t see that any...

Awesome! The math side of my brain is soothed by this!

I learned a lot about CC from this thread! It has me thinking about gross things! Couple questions: 1. Is there a 1:1 relationship between a given PPM of FC and when it becomes CC? In other words, if I have 10 FC and dump in enough pee to create 1 CC, is my FC 9 or somewhere less as part of...

If you had higher CYA, you might be able to run at 30% or something (you’d have to experiment for the exact number), which is 25% less demand on your SWG, potentially extending its life by 25%. Also, higher FC levels isn’t really relevant to production. If you run at 3 FC and start and end each...
