Hayward HCC 4000 pH/ORP WiFi Controller with Gold ORP Sensor
The Hayward HCC 4000 pH/ORP WiFi Controller with Gold ORP Sensor monitors pH and ORP while automatically making chemical feed decisions — and adds an upgraded gold ORP sensor, Hayward PoolComm app connectivity, internal 10-day chemical history logging, and an in-line strainer for enhanced sensor protection. Comes completely assembled with sensors included.
Like all HCC 4000 models, it calculates and displays derived free chlorine in PPM, features customizable chemical feed timing, and transmits unlimited chemical reading data wirelessly. The gold ORP sensor provides improved accuracy and longevity compared to standard sensors. Backed by a 1-year warranty on controller and sensors.
Key Features
Gold ORP Sensor

Frequently Asked Questions
What is the difference between this (HCC4000WIFIAU) and the standard HCC 4000 WiFi (HCC4000WIFI)?
The HCC4000WIFIAU upgrades to a gold ORP sensor, adds Hayward PoolComm app connectivity (vs. generic WiFi data transmission), includes an in-line strainer, and stores 10-day chemical history internally. The standard HCC4000WIFI has the same basic WiFi and PPM display capabilities but without the gold sensor, strainer, or PoolComm app integration. Choose the AU version for the full commercial feature set.
Why is a gold ORP sensor better than a standard one?
Gold electrode ORP sensors are less susceptible to poisoning from common pool chemicals — particularly cyanuric acid and certain algaecides — that can coat and degrade standard platinum or silver electrodes over time. Gold sensors maintain accuracy longer in commercial pool environments with variable water chemistry, reducing calibration frequency and sensor replacement costs.
What is the Hayward PoolComm app?
PoolComm is Hayward's commercial pool monitoring app that receives WiFi data from the HCC 4000 controller. It allows facility managers to remotely monitor pH and ORP readings, view historical data, and receive alerts — useful for multi-pool facilities or off-site management.
What does the 10-day history log store?
The controller internally stores daily average chemical readings (pH, ORP, and derived free chlorine PPM) for the past 10 days. This built-in log can assist with regulatory compliance documentation for commercial pool operators without requiring a separate data management system.
