Hayward Main Control Board Replacement for OmniLogic Automation Systems | HLX-PCB-MAIN

The Hayward Main Control Board Replacement (HLX-PCB-MAIN) is the OEM replacement main PCB for Hayward OmniLogic whole-home pool and spa automation systems.

IMPORTANT: LICENSED TECHNICIAN INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. Do not attempt to replace this board without proper qualification — the OmniLogic control system operates at mains voltage (120V/240V).

The main control board is the central processing unit of the OmniLogic automation system, managing communication between all connected devices, relays, and control interfaces. Replacing a failed or damaged control board restores full automation functionality — including scheduling, remote access, and connected equipment control — without replacing the entire OmniLogic enclosure.

Poolaroo Pro Tip

Before replacing the main control board, document your existing OmniLogic configuration — including schedules, device assignments, and network settings — as a board swap will require the system to be reconfigured from scratch. Your qualified technician should also verify that the control board failure is not caused by an upstream issue such as a faulty transformer or wiring fault, which could damage the replacement board if left unresolved. Consult Hayward's OmniLogic documentation for firmware compatibility requirements before installation.
