The Weil-McLain® Ultra U-Control™ Module (MPN: 511-724-951 / 383-500-658) is the factory-authorized brain assembly engineered to restore precision ignition sequencing and thermal safety across Ultra Series gas-fired condensing boilers. This advanced microprocessing control network actively manages system logic parameters, responding instantaneously to field signals from the room thermostat, low-water cutoff (LWCO), and air pressure switches.
Key Performance Features:
- Dynamic System Regulation: Controls the full boiler lifecycle—modulating gas valve timing, proving pilot flame integrity within a 15-second trial window, and commanding purging cycles to optimize efficiency.
- Multi-Circulator Coordination: Intelligently sequences system circulators, primary boiler pumps, and dedicated domestic hot water (DHW) loops simultaneously.
- Robust Electrical Protection: Designed with clean external fuse terminal channels to protect the underlying motherboard tracks against external field wiring spikes.
Compatibility Note: This genuine OEM replacement part is specifically optimized for seamless electrical integration into Weil-McLain Ultra Series 3, Series 4, and Series 1 Commercial high-efficiency boiler systems.
