Spa Manufacturers Using This Part
Because it is a standardized analog component from Balboa, it was commonly used in older (typically pre-2010) or more basic models from manufacturers that relied on Balboa's universal mechanical equipment:
Cal Spas: Frequently utilized these analog controls for their earlier value-tier portable spas.
Marquis Spas: Found in legacy models before the brand shifted primarily to advanced digital systems.
Artesian Spas: Used in specific older series as a basic control interface.
Coast Spas: Incorporates these standard analog components in their economy-focused legacy lines.
