Pentair IntelliCenter® 522475Z Wi-Fi Link Kit Client Bridge is included in the bundled systems, but must be ordered separately when ordering a la carte for the IntelliCenter Control Systems. IntelliCenter is Pentair's highest-capacity and most service-friendly control system ever. Communication with this system can be done on a wide range of devices and platforms. Many important service, programming and monitoring tasks can be done without an on-location service call. Order popular bundled systems and receive everything in one box or build systems a la carte.
