Hayward Main PCB for AquaTrol AQ-TROL-RJ, GLX-PCB-TROL-RJ

The Hayward GLX-PCB-TROL-RJ is the main printed circuit board for the AquaTrol AQ-TROL-RJ pool chlorine generator. It is the genuine Hayward part.

What the board does

The main PCB is the control side of the chlorinator. It reads the unit, drives the cell and runs the display, which is why a board failure looks like a total system failure even though the cell and the plumbing are untouched. Replacing the board puts the existing installation back to work without pulling out the enclosure or repiping anything.

Get the version right

AquaTrol has been sold in several versions and the boards are not interchangeable. Read the model tag on the unit and confirm it is an AQ-TROL-RJ, then check the number printed on the board that is coming out. This listing is the board alone.
