Product Overview
The Hayward HLIOEXPAND OmniLogic I/O Expansion Board is a genuine Hayward expansion accessory designed to add more control capacity to compatible Hayward OmniLogic pool automation systems. Instead of replacing the entire automation panel, this add-on board expands the system with additional valve actuator outputs, low-voltage dry contact relays, and temperature sensor inputs.
This makes the HLIOEXPAND ideal for pool and spa systems that need to control more equipment, such as valves, water features, heaters, sensors, lighting circuits, or other low-voltage automation functions. Once installed, the OmniLogic system detects the expansion board and allows the added inputs and outputs to be configured through the control system.
Ideal For
Residential pool and spa owners expanding an existing Hayward OmniLogic automation system
Pool/spa combinations that require additional valve actuator control
Systems with extra temperature monitoring needs
Backyards with more automated equipment than the base controller can support
Installations using Hayward OmniLogic smart control and app-based pool automation
Pool professionals upgrading automation capacity without replacing the full control platform
Key Features
Adds More OmniLogic Control Capacity
The HLIOEXPAND plugs into the OmniLogic base system to increase the number of available control points for connected pool and backyard equipment.
4 Additional Valve Actuator Outputs
This board provides four additional valve actuator outputs, allowing compatible automated valves to be integrated into more advanced pool and spa configurations.
4 Additional Low-Voltage Relays
The expansion board includes four additional low-voltage dry contact relay outputs for controlling compatible low-voltage equipment and automation functions.
4 Additional Temperature Sensor Inputs
The HLIOEXPAND adds four temperature sensor inputs, giving the OmniLogic system more flexibility for monitoring pool, spa, solar, or equipment-related temperature points when properly configured.
Designed for OmniLogic Systems
This accessory is made for Hayward OmniLogic pool controls and is intended to expand the capabilities of the base automation system.
Smart Automation Integration
When used with a compatible OmniLogic setup, the added inputs and outputs can be managed through the Omni platform, helping customers control more equipment from their automation interface and connected app experience.
Genuine Hayward Accessory
The HLIOEXPAND is a genuine Hayward expansion component, making it the correct choice for customers looking to maintain compatibility with Hayward OmniLogic automation equipment.
Benefits
The Hayward HLIOEXPAND gives pool owners and installers a clean way to expand automation capacity on an existing OmniLogic system. It helps reduce the need for workaround wiring or panel replacement when additional valves, sensors, or low-voltage control points are needed.
For more advanced pool and spa setups, this expansion board can make the automation system more flexible and complete. Whether the pool has multiple water features, added temperature monitoring, or extra controlled equipment, the HLIOEXPAND allows the OmniLogic platform to manage more functions from one integrated control system.

Customer-Facing Q&A
What does the Hayward HLIOEXPAND do?
The HLIOEXPAND expands a compatible Hayward OmniLogic automation system by adding more valve actuator outputs, low-voltage relay outputs, and temperature sensor inputs.
Is this the same as the Omni Smart Pool & Spa Control Configuration Guide?
No. The “Omni Smart Pool & Spa Control Configuration Guide” is a Hayward literature/resource title, while HLIOEXPAND is the actual OmniLogic I/O Expansion Board product referenced in that guide.
How many additional connections does it provide?
It provides 4 additional valve actuator outputs, 4 additional low-voltage relays, and 4 additional temperature sensor inputs.
Does this work with OmniLogic?
Yes. The HLIOEXPAND is designed for Hayward OmniLogic pool controls.
Are temperature sensors included?
Temperature sensors are not confirmed as included. Hayward documentation states that compatible Hayward 10k ohm thermistor-type temperature sensors are used and are not included.
Can homeowners install this themselves?
Professional installation is strongly recommended. The board installs inside the OmniLogic panel, and Hayward documentation warns that power must be shut off before accessing the panel.
Is this a full automation system?
No. This is an expansion board accessory. It is intended to expand an existing compatible OmniLogic automation system, not replace the main control panel.
