IC SWG "Sanitizer Output" lights flashing

[Jacquelyn1215]

We have an IC SWG. I need help understanding the “Sanitizer Output” LED lights. They had been flashing for several weeks and during this time the Salt Level was "good" per the light on the SWG. During that time, our FC has ranged from 2.6 - 4.8; today it was at 3 and those lights were still flashing. We had the output (on the app) set to 7%. That seems to be our sweet spot to prevent FC from getting too high. However, I’m guessing the Sanitizer Output lights aren’t meant to be flashing all the time? So we played with the output and it looks like if we set it at 11% or over, the lights stop flashing and just the first 2% light was illuminated consistently.

We will monitor this and see what it does to our chlorine levels but from experience it’s going to cause it to increase. What is the optimal setting here? Does it matter if the lights are consistently flashing?

Look at the numbers above and below the LEDs.

The numbers above the LEDs go from 2% to 10%.

The numbers below the LEDs go from 20% to 100%.

When the LEDs are flashing the top numbers apply and when the LEDs are solid the bottom numbers apply.

It also says “Flashing LEDs: Low Output Mode”. That means generation between 2% and 10%.

What's your CYA level? How are you testing? Do you have automation?

What's your CYA level? How are you testing? Do you have automation?

CYA is at 50. I use the Pool Math app & the Taylor test kit (forget which one) to test multiple times/week, typically 3 or 4. We do not have automation.

prevent FC from getting too high.

Your FC is at the low end, which doesn't give you much margin of error/safety. There's no downside if your FC is a little high. There's a big downside to your FC being too low.

I use the Pool Math app

You can share your PoolMath logs (enable at the bottom of the Pool Setup menu).

What app are you using and how does it interface with your system?
