Balboa Double Sensor Harness 30278

The Balboa Double Sensor Harness 30278 is designed for reliable temperature and hi-limit measurements in smaller Balboa spa systems. This assembly contains two sensors with different cable lengths and provides accurate monitoring and protection of the heating system.

The longer sensor measures the spa water temperature, while the shorter sensor acts as a hi-limit protection and is located on the rear of the heater.

Key Features:
Dual Function: Provides both temperature measurement and hi-limit protection.
Compatibility: Specifically designed for smaller Balboa applications.
Easy Installation: The sensors slide into their holders and connect directly to the PCB with a flat 2-pin plug.
Durable Design: Made from high quality materials for long lasting performance.
