The whole point is to centralize control of your system. This is what the GHL Products are all about. The Vortech control module will allow you to simplify your maintenance and feed pause settings, tie your pumps in to a single controller (even those from other manufacturers) for more complex wave patterns, storm simus, more flexible Night modes.
This isnt a "replacement" controller for the integrated Vortech controllers, its a control interface to manage them from your profilux. your Profilux will simply become the "Master" controller for the Vortechs which will operate in slave mode. This is how any 3rd party controller will operate the Vortechs
