The Spa-Quip SP500A and 54500 Conversion Kit is designed to replace obsolete PCBs used in Spa-Quip 54500 and SP500A spa control systems. As the original SP500A and 54500 circuit boards are no longer manufactured, this conversion kit provides a reliable and long-term replacement solution.
This kit allows you to upgrade your existing control system without replacing the entire spa pack. It is compatible with the following models:
54500-15
54500-20
SP500A15
SP500A20
The conversion kit restores full spa control functionality, including heater operation, pump control, filtration cycles, and system safety features.
An installation guide is supplied with the PCB to assist with setup and configuration.
