Genuine Balboa Replacement PCB.

This circuit board is used on many hot tubs and spas (see below) and is easily recognised by its manufacturers code 54126, it is M3 which means it needs a pressure switch to run and is not compatible with the more modern M7 systems.

The PCB is very easy to fit and can be tested by removing all plugged in components and testing via a multimeter.

If the panel looks odd when fitted change the 'Filter' from A to B.
