The 30337 (or 30337KIT) is a Balboa Water Group dual sensor assembly that includes both a temperature sensor and a high-limit sensor on a single 4-pin connector. It is widely used by many original equipment manufacturers (OEMs) that utilize Balboa control systems, particularly older "non-M7" systems that require external sensors rather than those built into the heater.
The following spa manufacturers have utilized the 30337 sensor assembly or compatible Balboa packs in their hot tubs:
Cal Spas (Replaces P/N ELE09900310 and ELE09900290).
Coleman Spas (Used for model years 1991–2000 and 2001–2002 600 & 700 Series).
Sundance Spas (Specifically for systems 701 and 724).
MAAX Spas (Commonly found in older models from the 1990s and early 2000s).
QCA Spas (Used in systems that typically feature pressure switches instead of built-in sensors).
