Hayward HCC 4000 WiFi pH and ORP Controller
The Hayward HCC 4000 WiFi pH and ORP Controller monitors pH and Oxidation-Reduction Potential (ORP) while automatically making chemical feed decisions to ensure safe levels and destroy harmful pathogens. A standout feature: it calculates and displays derived free chlorine in PPM directly on the controller — and transmits an infinite amount of chemical reading data wirelessly.
Built by Hayward with a fully assembled wireless design, customizable chemical feed options for fine-tuned timing and frequency control, and a direct wireless data transmission capability. Backed by a 1-year warranty on controller and sensors.
Key Features
WiFi Data Transmission
Wireless design transmits unlimited chemical reading data for remote monitoring and logging.
Derived Free Chlorine in PPM
Calculates and displays derived free chlorine concentration in PPM — beyond just ORP millivolts.
Automatic pH and ORP Control
Continuously monitors and automatically makes chemical feed decisions to maintain safe water chemistry.
Customizable Chemical Feed Options
User-configurable feed time and frequency for more consistent pH and sanitization levels.
Comes Completely Assembled
Ready to install out of the box — no assembly required.
Pathogen Protection
ORP-based monitoring ensures rapid deactivation of waterborne pathogens.
1-Year Warranty on Controller and Sensors
Hayward limited warranty coverage for both controller and sensors.
Who It's For
- Commercial pool operators who want wireless chemical data transmission and logging
- Facilities where PPM display of derived free chlorine is required alongside ORP
- Anyone who wants customizable feed timing for more precise chemical management
- Operators who need a fully assembled, WiFi-enabled pH/ORP controller

Frequently Asked Questions
What is "derived free chlorine" and why is the PPM display useful?
ORP measures the oxidizing power of the water in millivolts, but the actual free chlorine concentration in PPM is what most regulators and operators want to know. The HCC 4000 calculates derived free chlorine from the ORP reading and pH value and displays it directly in PPM — making compliance reporting and day-to-day monitoring more straightforward for commercial operators who think in chlorine PPM rather than ORP millivolts.
What does the WiFi connectivity do?
The WiFi design allows the HCC 4000 to transmit chemical reading data wirelessly — enabling remote monitoring, data logging, and integration with management systems without physical data cables. This is particularly valuable for commercial facilities that need chemical data records for compliance or multi-pool operations.
How does this compare to the HCC 2000?
Both are Hayward pH/ORP water chemistry controllers. The HCC 4000 WiFi adds wireless data transmission, derived free chlorine PPM display, and customizable feed timing options — making it better suited for commercial facilities that need data connectivity and PPM reporting. The HCC 2000 is the standard package with flow cell and sensor included. Both carry 1-year warranties.
