The ProfiLux Touch display provides an additional layer of convenience and point of access. With this accessory, you can view valuable information such as probe readouts and graphs. You can also setup 1-touch shortcut keys to trigger feed pauses, maintenance modes, and perform an Alkalinity test (KH Director required). If you wanted to manually turn on or off certain outlets, you can do that too. Ultimately, the touch display makes it easy to view and trigger commands as needed, even if your hands are wet!
