Product details

The Pentair 523770 is the replacement controller, or HMI, for the IntelliChlor Plus salt chlorine generator, in black. It is the module that carries the display and the controls: the part of the generator you read status from and adjust output on.

Replace the controller, keep the cell

The IntelliChlor Plus is built so that its electronics are separate from the cell and can be replaced in the field. A damaged or dead controller is swapped on its own, and the cell and the rest of the generator carry on.

This is a genuine Pentair part, sold as the controller only.

From Pool School

When to Replace a Salt CellThe life each manufacturer prints, what looks like a dead cell and is not, and choosing the next one. Read How to Clean a Salt CellHose first, acid only on scale that stays, and each manufacturer's own mix and time limit. Read
