Product Overview

The Hayward GLX-PCB-PRO Main PCB is a genuine OEM replacement control board designed for Hayward ProLogic and AquaPlus pool and spa automation systems. This main printed circuit board serves as the central electronic controller for compatible automation systems, managing connected pool and spa equipment, relays, valves, heaters, pumps, lighting, and chlorination functions.

Hayward lists the GLX-PCB-PRO for ProLogic and AquaPlus systems across all versions/date codes, making it the primary replacement board for these automation platforms.

Important Compatibility Notice

GLX-PCB-PRO should not be confused with the older AquaLogic GLX-PCB-MAIN board.

Hayward's current technical documentation identifies:

• ProLogic Main Board: GLX-PCB-PRO
• AquaPlus Main Board: GLX-PCB-PRO
• Older AquaLogic Main Board: GLX-PCB-MAIN

Always verify the automation system model and existing board before ordering.

Specifications

Installation Information

Replacement of the main PCB requires opening the automation control panel and working around electrical wiring and high-voltage components. Installation should be completed by a qualified pool automation professional or electrician familiar with Hayward control systems.

Disconnect and lock out all electrical power before servicing the automation panel.

Configuration and system programming may be required after the replacement board is installed.

Confirm Before Ordering

Please verify the automation system model and existing PCB before purchasing.

GLX-PCB-PRO is designed for Hayward ProLogic and AquaPlus systems.

For an older system specifically labeled AquaLogic, Hayward's current technical documentation identifies GLX-PCB-MAIN as the AquaLogic main board rather than GLX-PCB-PRO.

Do not order based solely on the appearance of the circuit board. Check:

• Automation system name
• Model number
• Existing PCB part number
• Local display type
• Relay configuration

before purchasing.

⚠️ Important Purchase Notice
