Product Overview
The Siemens LME1 / LME2 / LME4 series are burner control units designed to manage the automatic startup, ignition, flame supervision, and shutdown of gas (or gas/oil) burners operating in intermittent modes. These units are widely used in boilers, furnaces, hot air generators, and other combustion applications where reliable and safe burner operation is essential. They are built for compliance with safety standards such as EN 298, and support flame verification via ionization probes or compatible flame detectors.
Key Features
• Startup & Supervision: Designed to safely start and supervise 1- or 2-stage gas burners or gas/oil burners in intermittent operation.
• Flame Detection: Works with ionization probes or flame detectors (QRA and other types) for dependable flame supervision.
• Safety Compliance: Type-tested in accordance with EN 298 safety standards for burner controls.
• Undervoltage & Pressure Monitoring: Includes undervoltage detection and checks air pressure switch functionality during startup and operation.
• Remote Reset Facility: Allows electrical remote reset after a fault lockout.
• Status Indication: Multicolor LED indication for operational and fault signals.
• Controlled Operation: Limits restarts and supports controlled intermittent operation even after prolonged run times.
• Digital Control: Digital signal processing ensures accurate control sequences.
Applications
• Residential & Commercial Boilers – Controls gas burners for heating water and space heating.
• Industrial Heating Systems – Suitable for furnaces, ovens, and hot air generators requiring automated combustion control.
• Process Combustion Equipment – Used in low to medium-capacity combustion applications where intermittent burner operation is needed.
