Salt Chlorination and Automation Use
This system is designed to support salt-based chlorine production while also helping manage pool and spa control functions. If you are researching the same system in more detail, review the Hayward AquaPlus salt chlorinator information before choosing the correct setup for your pool.
The system still requires regular water testing, balanced pool chemistry, correct salt levels, and proper circulation. Automation can help with control, but it does not remove the need for routine maintenance.
Chemical Automation Notes
The AquaPlus system may be used with compatible chemical automation components to help monitor and manage sanitizer and pH control. If your setup needs chemistry automation support, compare the Hayward Sense and Dispense system to understand related parts and compatibility.
Chemical control performance depends on clean probes, correct calibration, proper water flow, and balanced pool water. Old or dirty probes can cause inaccurate readings, so they should be inspected regularly.
Probe and Sensor Compatibility
If the system uses ORP monitoring, a compatible Hayward ORP probe may be required for sanitizer control readings. Match the probe model with your existing Hayward control system before ordering any replacement sensor.
For pH monitoring, check whether your setup requires a separate Hayward pH probe. ORP and pH probes are different parts, and both may need calibration or replacement depending on system age and water conditions.
Before You Buy
Choose this system only if the PL-PLUS-20G model matches your pool size, automation needs, and existing Hayward equipment. Confirm whether the package includes the control panel, salt cell, probes, sensors, flow switch, wiring, and installation hardware.
Also verify installation requirements, electrical setup, plumbing location, warranty terms, and return policy before purchasing. Professional installation is strongly recommended for pool automation and chemical control systems.
