Pentair IntelliChlor Plus and LT Replacement Sensor Board

The Pentair 523769 is the replacement sensor board for the IntelliChlor Plus and IntelliChlor LT salt chlorine generators. One part covers every model in both families.

The Plus and LT cells are designed in modules, and the sensor board is one of them. That means a sensor fault is fixed by swapping this board rather than replacing the cell. Pentair measured the difference in its own lab: replacing the sensor module on an IntelliChlor Plus 30 took 53% less time on average than the same job on an IntelliChlor 15. Results will vary with the installation.

The controller (HMI) is a separate module and a separate part. If you are opening the cell, a 10 pack of IntelliChlor gaskets is worth having on the truck.
