Pentair 523769 Intellichlor Sensor Board Replacement

Product Description

The PENTAIR 523769 is a replacement sensor board designed for IntelliChlor Plus and IntelliChlor LT salt chlorine generator systems. The sensor board is the component responsible for detecting and monitoring chlorine production within the cell, and replacing it restores accurate system readings and proper generator function. This is an OEM-style replaceable module intended for pool service professionals and qualified technicians performing maintenance or repair on salt chlorine generator equipment. Internal lab testing reported an average time savings of 53 percent when replacing the sensor module on IntelliChlor Plus compared to earlier IntelliChlor models.

This sensor board is suited for residential and light commercial pool installations using Pentair IntelliChlor salt chlorine generators. It is the correct replacement part for systems that display sensor faults, inaccurate salinity readings, or loss of chlorine output tied to sensor failure. Pool service technicians performing seasonal maintenance, troubleshooting, or component-level repair will find this a direct-fit replacement for the supported generator models.

Key Features

• Designed as a replaceable sensor module for faster field servicing
• Compatible with all models of IntelliChlor Plus and IntelliChlor LT generators
• Restores accurate chlorine production monitoring and salinity sensing
• Component-level replacement avoids full cell or control board swap-out
• Based on Pentair internal lab testing showing reduced replacement time versus earlier IntelliChlor models

Compatibility

Designed for use with all models of the Pentair IntelliChlor LT and IntelliChlor Plus salt chlorine generator series.

Installation Notes

Installation should be performed by a qualified pool service professional. Power to the salt chlorine generator and the pool equipment circuit must be shut off at the breaker before beginning any sensor board replacement. Follow all applicable local electrical codes and the manufacturer service documentation for disassembly and reassembly procedures. Do not operate the generator with the sensor board removed or improperly seated.
