Weil McLain 383-500-665 Control Module
The Weil-McLain 383-500-665 Control Module is the professional-grade U-Control Upgrade Kit engineered specifically for Ultra Series 1 and Series 2 gas boilers. This OEM boiler control board is a comprehensive field-integration solution, serving as the official 383-500-191 replacement. It is critical for technicians to note that this is an upgrade kit, not a standard drop-in component. The 383-500-665 provides advanced diagnostics and enhanced ignition sequencing for models including the Ultra 80, 105, 155, and 233. By integrating this boiler control module, contractors can ensure high-fidelity modulation accuracy and improved system safety. The U-Control hardware manages combustion management and temperature monitoring through updated firmware, resolving common boiler lockout codes and communication failures found in older MCBA modules. Utilizing this factory-authorized part maintains the intended boiler operating efficiency and facilitates field upgrade integration for long-term reliability in residential and commercial hydronic applications.
Key Benefits:
- Direct OEM Upgrade: Engineered to replace obsolete 383-500-191 and 511-330-258 modules with modern U-Control technology.
- Enhanced Troubleshooting: Provides detailed fault diagnostics and operational feedback to reduce on-site maintenance time.
- Comprehensive Kit: Includes the U-Control module, updated display board assembly, and required wiring harnesses for Series 1 and 2 applications.
- Precise Modulation: Optimizes boiler firing rates and blower speed based on real-time data from supply and return sensors.
Common Questions:
- Is this a direct plug-and-play replacement for my existing board? No, this 383-500-665 kit is an upgrade kit. It requires replacing both the control module and the display panel, as the older MCBA style is not compatible with modern U-Control logic.
- Which boiler models are compatible with this upgrade? This kit is designed for Weil-McLain Ultra Gas Boilers, specifically the Ultra 80, 105, 155, 230, and 233 units within Series 1 and Series 2 production runs.
- Do I need to record settings before removing the old module? Yes, contractors should document all Priority 1-3 settings and setup parameters from the existing control to ensure accurate configuration of the new upgrade kit.
