Due to Covid-19 supply chain issues, Balboa Water Group is currently out of stock of these PCBs. They are due January 2021, but Balboa is not giving *real* ETAs. Backorders are prioritized. It is unlikely anyone else will have these, as this is a global issue. Sorry for any inconvenience.
January 2021 Update: Balboa now says they may not be here by January.
Balboa GS501Z circuit board, always in stock. Also suits SCS501 (SCS501 1005), and all GS501Z controllers. Older PCBs are often damaged in power surges, or due to bad/worn relays.
Note: It looks different to original PCB from the SCS 501 controllers but it still fits properly and has the same functions.
It may have a bar code number of 54512, 53341, 55514 ,53341, etc. To ensure a correct match, do not go by the "GS500 or GS500Z" stamped into the left corner of the board as this is common to the entire range, look on the software chip label for an exact match.
This PCB can have the following set up functions: 1. 1x Circ Pump, 1x 1 Speed Pump, 1x Blower, Ozone, Light. 2. 1x 2 Speed Pump, Blower, Light, Ozone.
