Product Description

Expand your pool automation system with the Hayward Omni RS485 Smart Relay Kit. Designed for compatible Hayward Omni controllers, this external smart relay adds another switchable high-voltage equipment circuit to the automation system.

The relay communicates with the connected Omni controller through a wired RS485 connection. Once installed and configured, compatible equipment can be operated through the Omni control interface, supported schedules, and the Hayward Omni mobile app.

The HLH485RELAY can control compatible 115V or 230V pool equipment, including single-speed pumps, pool and landscape lighting, water-feature pumps, cleaners, transformers, and other approved electrical loads. It is rated for loads up to 20 amps at 230V.

For installation convenience, the kit includes a single-gang electrical box and a 6-foot wiring whip. The relay also features a manual on/off service button that can be used if communication with the automation controller is interrupted.

This product is an automation expansion accessory. It requires a compatible Hayward Omni control system and does not operate as a standalone Wi-Fi relay.

Product Benefits

Expand Your Existing Automation

Add another controllable equipment circuit without replacing the complete Hayward Omni automation system.

Convenient Remote Equipment Control

Once connected and configured, the relay allows compatible equipment to be managed through the host Omni controller and supported mobile controls.

Supports Multiple Equipment Types

The relay can switch approved high-voltage pool and backyard equipment, including lighting, single-speed pumps, cleaners, water features, and transformers.

Flexible 115V or 230V Installation

The smart relay supports compatible equipment operating on either 115V or 230V power. A neutral conductor is required for 115V applications.

Installation Components Included

The supplied electrical box and 6-foot wiring whip help simplify installation at the equipment pad.

Manual Service Control

A built-in manual on/off button allows the connected circuit to be switched locally if communication with the Omni controller is lost. The button is not intended for routine use while normal communication is active.

Specifications

Hayward’s current product record identifies SKU HLH485RELAY, GTIN 610377363457, a 4-pound shipping weight, 7.5 × 10 × 10-inch shipping dimensions, and a one-year parts warranty.

Compatibility

Designed for supported Hayward Omni automation systems, including compatible configurations within the following product families:

• Hayward OmniHub
• Hayward VS Omni
• Hayward OmniPL
• Hayward OmniLogic
• Other Hayward Omni controllers that support the HLH485RELAY external smart relay

Compatibility depends on the automation-controller model, available communication-bus capacity, software configuration, connected electrical load, and installation layout.

Before ordering, confirm:

• The controller supports external RS485 smart relays
• An available relay position can be configured
• The connected equipment operates on 115V or 230V
• The equipment load does not exceed the relay rating
• The relay can be mounted within communication-cable reach
• The installation meets current electrical and pool-equipment codes

Hayward identifies the Omni RS485 Smart Relay as an accessory that expands relay capacity across compatible Omni control systems.

Common Applications

The HLH485RELAY may be used to control compatible equipment such as:

• Single-speed pool pumps
• Single-speed spa pumps
• Booster pumps
• Water-feature pumps
• Pool and spa lights
• Landscape or yard lighting
• Pool cleaners
• Lighting transformers
• Chemical-dispensing equipment
• Other approved 115V or 230V accessories

The exact circuit must be evaluated against the relay rating, equipment nameplate, circuit protection, and applicable electrical codes.

Variable-speed pumps normally use a dedicated communication connection for speed and schedule control. Do not assume a variable-speed pump should be routinely switched through this relay unless the pump and automation instructions specifically permit that configuration.

Installation Information

The smart relay handles line-voltage electricity and should be installed by a qualified electrician or pool-automation professional.

General installation considerations include:

1. Disconnect all electrical power before beginning service.
2. Confirm the connected equipment voltage and current requirements.
3. Mount the relay within the permitted distance from the Omni wiring panel or hub.
4. Use the included electrical box or a compatible box with a minimum volume of approximately 16.2 cubic inches.
5. Use nonmetallic conduit and connections with the supplied plastic box.
6. Connect the relay communication wiring to the proper Omni low-speed or RS485 communication bus.
7. Route separately supplied line power through the relay to the connected equipment.
8. Provide a neutral conductor when controlling 115V equipment.
9. Ground the relay box and connected equipment according to code.
10. Configure the relay through the Omni automation-system setup menu.
11. Restore power and test manual, scheduled, and remote operation.

The included wiring whip is intended for installations where the electrical box is located within approximately 6 feet of the power source. The relay should remain accessible for inspection and use of the manual service button.

Important Electrical and Safety Information

• Disconnect power at the circuit breaker before opening or servicing electrical equipment.
• Verify that the circuit is de-energized with an appropriate testing instrument.
• Do not exceed the smart relay’s approved electrical rating.
• Use properly sized copper conductors and circuit protection.
• Use GFCI protection where required, including applicable pool and spa lighting circuits.
• Do not use this relay to control an automatic pool cover.
• Do not use this relay to control a fire pit or fire feature.
• Do not operate the relay with exposed wiring or an unsecured electrical-box cover.
• Follow the automation-controller and connected-equipment wiring diagrams.
• Comply with all applicable national, state, and local electrical codes.

Incorrect installation can cause electrical shock, fire, equipment damage, serious injury, or death.

Frequently Asked Questions

Is this a complete Hayward Omni automation system?

No. The HLH485RELAY is an external smart relay accessory. A compatible Hayward Omni controller is required.

Does the relay connect directly to Wi-Fi?

No. The relay communicates with the compatible Omni controller through a wired RS485 connection. The host automation system provides supported network and mobile-app access.

What voltage equipment can it control?

The relay can control compatible 115V or 230V AC equipment.

What is the maximum relay rating?

Hayward documentation rates the smart relay for loads up to 20 amps at 230V. Always verify the connected equipment’s nameplate rating before installation.

Is the electrical box included?

Yes. The kit includes a single-gang electrical box.

Is a wiring whip included?

Yes. A 6-foot wiring whip is included.

Does it include a communication cable?

The smart relay is supplied with an attached communication cable intended for connection to the compatible Omni wiring panel or hub.

Can it control pool lights?

Yes, provided the lighting circuit, transformer, voltage, GFCI protection, and total load meet the installation requirements.

Can it control a single-speed pump?

Yes, provided the pump’s voltage and electrical load fall within the relay rating.

Can it control a variable-speed pump?

Compatible variable-speed pumps are normally controlled through their dedicated communication connection. The relay may only provide basic on/off switching in certain approved applications and does not provide variable-speed control by itself.

Can it control a two-speed pump?

A two-speed pump typically requires two properly configured smart relays to control both high- and low-speed circuits.

What does the manual button do?

The manual on/off button can toggle the relay if communication with the Omni controller is lost. It is not active during normal communication.

Will it work with non-Hayward automation systems?

It is designed for compatible Hayward Omni automation systems. Compatibility with third-party controllers is not supported unless specifically approved by Hayward.

Is professional installation recommended?

Yes. Installation involves line-voltage wiring, grounding, circuit protection, and automation-system configuration.
