Balboa Water Group g1900 Daughter Board Single Speed Pcb

Product Description

The BALBOA WATER GROUP g1900 is a secondary printed circuit board (PCB) designed to expand pump output capability in compatible spa control systems. Known as a daughter board, it mounts alongside the main control board and provides an additional single-speed pump circuit. This component is used by pool and spa service technicians when a system requires more than one pump output channel. The g1900 ships with new mounting hardware, making it a ready-to-install replacement or expansion module for qualifying Balboa control systems.

The g1900 daughter board is installed in residential and commercial spa applications using Balboa VS-series control systems. It is the secondary board within these systems, adding a dedicated 1-speed pump output channel to the control assembly. Spa technicians typically encounter this board when servicing multi-pump hot tub installations or replacing a failed expansion board in an existing VS-series setup. Mounting hardware is included, so no separate hardware sourcing is required.

Key Features

Compatibility

The g1900 is the secondary expansion board used in VS510SZ and VS510DZ Balboa control systems, where it serves as an additional 1-speed pump output module.

Installation Notes

Installation of this PCB should be performed by a licensed pool and spa technician. Always disconnect and lock out power to the spa at the main disconnect before handling any control system components. Follow the equipment manufacturer's wiring diagram when connecting pump outputs, and ensure all connections are secure before restoring power. Local electrical codes and NEC requirements for hydromassage equipment apply.
