Maintain optimal hydronic safety with the Weil-McLain LWCO Control Module, specifically engineered to manage boiler water level monitoring. This electronic unit, part number 381-330-039, acts as a primary safeguard against dry firing and overheating conditions, providing seamless integration with compatible Weil-McLain boiler systems.
The module functions by continuously tracking the water level within the boiler heat exchanger. When the system detects that fluid levels have fallen below the critical set point, the control triggers an automatic burner shutdown, effectively preventing physical damage to the heat exchanger and associated hydronic components.
Key System Performance Baselines:
- Automatic Safety Shutdown: Instantly de-energizes the burner circuit upon detecting low water conditions.
- Precise Monitoring: Uses electronic sensing to determine fluid levels with high repeatability.
- Robust Construction: Engineered to withstand the specific thermal demands of both residential and commercial hydronic environments.
⚠️ Application Profile: This module is specified for use in Weil-McLain hydronic boiler systems requiring active low-water cutoff protection to ensure safe operation and longevity of the pressure vessel.
