Hayward AQRS340 is an AquaRite S3 salt system designed for pools up to 40,000 gallons. This model provides salt chlorination plus basic built-in control for key pool equipment, including heater and variable-speed pump control, while stopping short of full Omni web automation. It features an LCD color display, a clear TurboCell for easier inspection, broad salt-range operation, and an upgrade path to Omni controls later if needed.

Product Overview

The Hayward AQRS340 AquaRite S3 is built for pool owners who want more than a basic chlorinator but do not need full Omni automation right away. It automatically generates chlorine from salt and also adds basic equipment control at the pad, letting you manage chlorine production, heater functions, and variable-speed pump operation from the built-in color display. That makes it a strong fit for pools where you want salt sanitization plus practical on-site automation without stepping up to the web-enabled Omni version.

Your wording “Automation. No Omni.” is accurate if you mean basic built-in equipment control, but not full Omni app/web automation. Hayward distinguishes the AQRS340 from the AQRS340OMNI: the Omni model adds broader automation features like app control, valve control, OmniDirect lighting control, and expansion into a more complete automation platform.
