The Pentair Intellicom II Adapter Interface is used with the Intelliflo pump to communicate between the pump and a Jandy or Hayward automation system. The interface has four relays to allow automation systems to use four individual speeds on the Intelliflo pump. It can also be used to expand existing Compool systems and allow you to have more relay spots for more pumps, lights, etc... The Intellicom II is very compact and light and can be installed within the cabinets of most automation systems.
