Matt,
I use my PC about 99% of the time.. For me it is 10 x better than my phone.
You can go to Pentair website and download it.
That said, almost anything you can do in ScreenLogic, you can do using the little LCD on the main panel.
Menu, Settings, IntelliChem. Enable.
We are not great fans of the IntelliChem system here at TFP, but I hope it works well for you. It is kind of like Autopay at your bank. Some people love it, but I like to be in control of what is happening and not relying on something to do it for me.
Thanks,
Jim R.
