I have a Hayward OnCommand system with a bad clock. Other than seemingly random jumps the clock never changes. I saw another thread that suggested to swap the main board (GLX-PCB-ONCOM). Can the main board simply be swapped with a new one? Or is calibration or custom setup of the new board required, specific to my own pool equipment?
