Balboa Kretskort GS510SZ
This printed circuit board is a spare part for Balboa GS501SZ, GS504SZ, GS510SZ, GS511SZ, GS512SZ, GS513SZ and GS514SZ control systems. The GS510SZ and GS514SZ systems also include a X-P231 55025 expansion board, which you should purchase separately, if needed.
To avoid any risk of error while ordering the motherboard, please ensure that you have the correct reference for the control system. The reference either on the label on the casing or on the bottom-right corner of the motherboard itself. Do not be distracted by the reference printed in the bottom-left corner of the motherboard (typically GS500Z), as it is only an indication of the basic series of circuit board used.
This board is only compatible with Balboa’s plastic casings, it will not fit the old metal ones.
