The G1110 circuit board serves as the direct replacement for legacy Balboa models 56298-01/-02, 56297-01/-02, and base 56299-01/-02 configurations. Engineered for seamless integration, this board is specifically designed to work with standard four-button Balboa VL200, VL240, and VL260 topside control panels featuring temperature adjustment buttons positioned on the right side of the control interface.
