Made by Balboa
Balboa Replacement: 54516 - GS501SZ PCB
This is a brand new PCB (Printed Circuit Board) from Balboa and should only be used to replace a faulty board of the same type.
This PCB can be used for many combinations of components, but it is best to stick to the specific that it is designed for - see list below.
The 54516 PCB's will only fit a balboa plastic control box.
When fitting remember to adjust the small jumpers to the same as the board you are replacing. If the panel looks odd when fitted change the 'Filter' from A to B.
