The Jandy AquaLink RS Control System has multiple configurations. Most setups are limited to the standard one box AquaLink System for 8 functions. The system discussed here has two interlinked control boxes to handle up to 16 functions. The first control box is called the Primary Power Center and the second control box is called the Auxilliary Power Center. Each Power Center has its own unique Printed Circuit Board (PCB). This guide shows you how to replace a Jandy AquaLink RS AUXILLIARY Power Center Circuit board. see our guide on "How To Set Up In Ground Pool Equipment - Part 6 - Control" for examples of the types of functions that can be controlled by this system.
VIEW 8 AUX TERMINALS - Pull the 8 red terminals off the bottom edge of the PCB. Note , we marked these individual cables before we realized that they were already labeled. See insert on the right side of the picture. Each terminal should be labeled: with a number on the side of the terminal and a "AUX B#" notation where the terminal plugs into the PCB. In the example shown; a seven is on the terminal and "AUX B7" is along side the base.
