I’ve installed the S3. No pool company around here knows anything about it. It’s been frustrating to say the least. Nothing on YouTube etc… to help, and Hayward is a bit quit on helping me because I’m not a pool company. But I think I have it going and working correctly. A little confused on the ORP settings. I have a saltwater pool. Any help would be appreciated! I also have the Omni upgrade package. Kind cool seeing all my information from my cell phone.
