Weil McLain 381-330-028 - 381-330-028 Control Module

Maintain precise control over your hydronic heating system with the factory-authorized Weil-McLain 381-330-028 control module. Serving as the primary central processing unit, this hardware ensures seamless ignition sequences and accurate temperature regulation, restoring reliable heat output to your boiler system by replacing your existing 381-330-028 unit with a genuine OEM component.

This module maintains operational integrity by continuously monitoring flame rectification and integrated pressure switches. Through high-speed logic, it manages complex sequences including prepurge, ignition trials, and post-purge cycles, providing real-time diagnostics that prevent short-cycling and protect the boiler's internal components from premature wear.

Key System Performance Baselines:

• Flame Rectification: Continuously monitors burner status for safe operation.
• Sequence Management: Automatically handles precision timing for prepurge and ignition cycles.
• Safety Interlocking: Processes data from pressure switches to prevent hazardous firing conditions.
• Diagnostic Logic: Identifies cycle fluctuations to enhance overall equipment longevity.

⚠️ Application Profile: Designed for use in compatible Weil-McLain residential and light commercial hydronic boilers requiring precise ignition and system safety integration.
