Hayward GLX-PCB-PRO Main PCB — AQL-Compatible ProLogic Control Board (All Versions)

Hayward GLX-PCB-PRO replacement main PCB for ProLogic automation systems. Built to be fully compatible with AQL panels, this control board supports every released AQL firmware revision for seamless drop-in swaps. Manufactured to Hayward OEM standards, the board contains the necessary firmware and relay hardware to restore or upgrade automated pool controls. Functionality restored includes schedule programming, pump and valve activation, heater management, lighting control, and remote interface services. Engineered for easy installation, the GLX-PCB-PRO mounts into the existing control box and uses the original wiring—no rewiring required. When a ProLogic panel stops communicating, fails to run schedules, or reports errors, installing the GLX-PCB-PRO provides a reliable, cost-effective way to return full system operation. Manufactured by Hayward.
