IMPORTANT UPDATE: The VS300 series has been discontinued by the manufacturer. Orders now ship with the VS501Z circuit board, which features additional receptacles but maintains identical fit, function, and programming capabilities.

This Balboa control board is designed to manage a single pump spa system with lighting control. Compatibility is determined by your existing chip number—if your current board displays VS300FLXR1(x) with any digit in the X position, this replacement will work perfectly for your application.

Typically paired with 4-button topside control panels, this circuit board appears in numerous hot tub brands including Viking, Freeflow, Nordic, and Aquaterra models. Also cross-references to part numbers 55341, FREE300, and 3-60-0100.

Return Policy Notice: All circuit boards are considered final sale items and cannot be returned or exchanged.
