It is a wireless link. The wireless link has ScreenLogic Interface on the house side device. The Intelllicenter document has references to ScreenLogic2 in the wireless diagrams.If your pool builder installed a ScreenLogic interface in your IntelliCenter then they do not know what they are doing. IntelliCenter does not use ScreenLogic. They may have installed a wireless link but it was definitely not ScreenLogic.
