Hayward AQL-RELAY-AC-KT Double Pole AC Relay Kit
The Hayward AQL-RELAY-AC-KT was an OEM high-voltage relay accessory designed for compatible Hayward Aqua Logic and Pro Logic automation systems. It allowed a Valve 3 or Valve 4 control output to operate higher-voltage pool equipment such as pumps, cleaners, lighting, or other auxiliary loads.
Hayward Manufacturer Supersession
Hayward's current replacement path moves compatible legacy automation systems to the OmniPL platform. The HLPROUPG replaces substantially more than the original relay accessory, so system compatibility should be confirmed before ordering.
What Replaces the Hayward AQL-RELAY-AC-KT?
Hayward lists the HLPROUPG OmniPL Retrofit Kit as the replacement SKU for the discontinued AQL-RELAY-AC-KT. However, HLPROUPG is a full automation upgrade rather than an individual double-pole relay. Customers replacing an AQL-RELAY-AC-KT should confirm their existing Hayward controller model and system configuration before purchasing the retrofit.

What Was the AQL-RELAY-AC-KT Used For?
The AQL-RELAY-AC-KT converted a compatible Hayward automation system's valve control output into an ON/OFF high-voltage relay output.
On compatible PS-4 systems, one or two relay kits could be connected using the Valve 3 and Valve 4 outputs. On compatible P-4 systems, one relay kit could be operated from the Valve 3 output.
Depending on the automation configuration, the relay output could be programmed for functions including timed equipment operation, solar, in-floor cleaning, manual control, or other supported automation functions.
HLPROUPG OmniPL Replacement Information

- Upgrades compatible legacy automation to Hayward's Omni platform
- Includes an external relocatable touchscreen control display
- Provides four integrated relays with expansion capability
- Supports control of compatible variable-speed pumps
- Provides OmniLogic app connectivity for remote system control
- Supports compatible Omni remotes and automation accessories

Compatibility & Fitment Guidance
If you are replacing an existing AQL-RELAY-AC-KT, do not assume that another Hayward relay with a similar appearance is automatically interchangeable.
The original AQL-RELAY-AC-KT used a dedicated wiring harness connected to the controller's Valve 3 or Valve 4 circuit. Hayward now directs customers to HLPROUPG as the replacement SKU rather than identifying a current individual relay as a direct substitute.
For best results, verify the exact model number of your existing Aqua Logic, Pro Logic, AquaPlus, or E-Command controller before ordering the OmniPL retrofit.
Frequently Asked Questions
Is Hayward AQL-RELAY-AC-KT discontinued?
Yes. The AQL-RELAY-AC-KT is no longer the current Hayward relay solution, and Hayward identifies HLPROUPG as its replacement SKU.
What is the replacement for AQL-RELAY-AC-KT?
Hayward identifies the HLPROUPG OmniPL Retrofit Kit as the replacement.
Is HLPROUPG a direct replacement relay?
No. HLPROUPG is a complete automation retrofit that upgrades compatible legacy Hayward automation systems to the OmniPL platform.
Can I replace AQL-RELAY-AC-KT with GLX-RELAY?
Hayward does not identify GLX-RELAY as the manufacturer supersession for AQL-RELAY-AC-KT. For that reason, it should not be treated as a guaranteed direct substitute without system-specific verification.
What systems originally used AQL-RELAY-AC-KT?
Hayward originally specified the relay kit for compatible Aqua Logic and Pro Logic P-4 and PS-4 automation systems.
How much equipment could the original relay control?
Hayward rated the original relay kit for high-voltage equipment loads up to 3 HP / 30A at 240VAC or 1-1/2 HP / 30A at 120VAC.
Installation & Electrical Safety
Pool automation equipment can contain hazardous line voltage. Power should be disconnected before servicing, and installation or retrofit work should be performed in accordance with Hayward documentation and applicable electrical codes. If you are unsure whether HLPROUPG is appropriate for your existing automation system, confirm the controller model and equipment configuration before purchase.
Need Help Confirming the Replacement?
If you are replacing an AQL-RELAY-AC-KT and are unsure whether your existing Hayward automation system is compatible with the HLPROUPG OmniPL retrofit, send us the model number from your current control panel. Aqua Terra Backyard can help identify the appropriate manufacturer replacement path before you order.
