The Hayward GLX-PCB-PRO is the main circuit board for the Goldline ProLogic and AquaPlus automation and chlorination controls, for all versions manufactured after October 2008.
What it does
The ProLogic runs pool automation and the salt chlorinator from a single control, and this is the primary board behind both. When the board fails, the control is dead or misbehaving even though the enclosure, wiring and cell are fine, and replacing the PCB is the repair.
Check the date
This board is for units built after 10/2008. Confirm the manufacture date on your control before ordering. It is a genuine Hayward part.
