The Hayward OmniLogic System Expansion Board is built to keep your pool equipment running the way it should.

The Hayward OmniLogic System Expansion Board (HLIOEXPAND) is a genuine OEM add-on module that extends the capabilities of your Hayward OmniLogic smart automation platform. This expansion board provides extra relay outputs, sensor connections, and control inputs—allowing you to manage more pumps, lighting circuits, valves, heaters, chemical systems, and specialty equipment than the base controller supports.

Designed specifically for use with OmniLogic automation hubs, the HLIOEXPAND board enables complex equipment configurations with centralized programming and scheduling. Whether you’re adding water features, extra automation routines, or advanced chemical control, this expansion board helps your system grow without the need to install a second control center.
