Poolaroo Pro Tip
Before ordering, confirm your existing control system is an AquaLogic or ProLogic model — not an OmniLogic or earlier Goldline unit, which use different board configurations. If your system is already running T-CELL-3 or T-CELL-9 salt cells or an EcoStar variable-speed pump and the main board has failed, GLX-PCB-PRO is the correct service replacement. Always power down the system fully at the circuit breaker before handling any control board component.
