What Does the Balboa G1920 Board Do?
The G1920 functions as an expansion board for a compatible Balboa spa control pack. It provides the relay and electrical connections required for the system to operate an additional 2-speed pump when the main control board does not have enough built-in equipment outputs.
Because spa systems can use similar-looking boards with different amperage ratings, programming or equipment configurations, the complete part number on the original board should always be verified before replacement.
Frequently Asked Questions
Yes. The G1920 is the listed replacement for the discontinued Balboa 55137 X-P332 2-speed expander board.
No. This is a daughter or expander board used alongside a compatible main Balboa control board. It is not a complete spa control pack.
No. Several spa boards may look similar while using different relays, ratings or system configurations. Match the replacement using the original Balboa part number and control-system requirements.
Professional installation is strongly recommended. Spa control systems contain high-voltage electrical connections and must be completely disconnected from power before service.
Compare the part number printed on your original board before ordering. For additional help, send Aqua Terra Backyard a clear photo of the original circuit board, its identification label and the spa control-pack label.
