The Hayward GLX-PCB-MAIN is the main printed circuit board for Goldline AquaLogic automation systems. It is a replacement PCB assembly that serves as the central control board and interfaces with T-Cell-3, T-Cell-9, and T-Cell-15 salt chlorinator cells. This part fits AquaLogic systems across all versions and date codes; ProLogic/AquaPlus models use GLX-PCB-PRO.
