Balboa circuit boards are marked with a “Chip Number” that is located on a white label placed on the logic chip near the center of the board. It is imperative that this number is supplied to Horizon Spa & Pool Parts for proper circuit board match. Just because boards may look similar the programming may not allow it to work properly in all applications.
