Protect your hydronic heating system from dry-firing damage with this original equipment LWCO control module designed specifically for the CGa-3 series. The 381-330-038 acts as a reliable safety interface, ensuring water levels remain at operational thresholds before the boiler initiates its combustion sequence.
This control board monitors electrical impedance between the internal water level probe and the boiler chassis. If the water level drops below the established safety threshold, the module triggers an immediate interruption to the gas valve circuit, effectively locking out the burner to prevent severe thermal stress on the heat exchanger.
Key System Performance Baselines:
- Safety Interlock: Automatically interrupts burner ignition during low water conditions.
- Probe Monitoring: Detects water presence via precise electrical impedance sensing.
- Seamless Integration: Engineered specifically for direct compatibility with CGa-3 burner control logic.
- Thermal Protection: Prevents catastrophic heat exchanger failure due to dry-firing.
⚠️ Application Profile: Essential for residential and light commercial hydronic boilers, specifically the Weil-McLain CGa-3 series, to ensure code-compliant safety and equipment longevity.
