Description

Product Overview
The Siemens LMO14 / LMO24 / LMO44 series are microcontroller-based oil burner control units designed for automatic startup, safe supervision, and ongoing control of forced-draft oil burners in intermittent operation. These controls are engineered for robust performance, built-in safety interlocks, and seamless integration into heater or boiler systems. They share housing dimensions, electrical connections, and flame detector compatibility with related Siemens burner control lines, making them flexible choices for OEMs and system integrators.

Key Features

  • Microcontroller-based control logic: Ensures accurate and reproducible control sequence, supporting reliable burner startup and operation.

  • Startup and supervision: Designed for both single-stage (LMO14) and two-stage (LMO24 / LMO44) forced-draft burners.

  • Flame detection compatibility: Supports supervision with photo-resistive (QRB) or blue-flame (QRC) detectors, improving safety and detection accuracy.

  • Safety and diagnostics: Includes undervoltage detection, electrical remote reset, multicolor status/fault indication, and limitation on ignition retries.

  • Oil pre-heater support: Provides a bridging contact and time monitoring for oil pre-heating where needed.

  • Designed lifetime: Built for extended functional service life under normal conditions, suitable for long-term industrial or commercial use.

Applications
These burner controls are used in:

  • Heating systems with forced-draft oil burners requiring reliable management of combustion sequences.

  • Industrial and commercial boiler applications where flame supervision, controlled ignition, and safety interlocks are essential.

  • OEM burner products that integrate control electronics for intermittent operation in compliance with standards such as EN 267 and DIN EN 298 (in relevant regions).

  • Direct-fired air heaters (especially with LMO44 variants).

Why Choose This Product

  • Proven reliability: Siemens burner controls are built with a safety-focused microcontroller platform and diagnostic feedback systems.

  • Enhanced safety: Integrated flame supervision, undervoltage detection, and controlled ignition logic improve operational safety and protected heater control.

  • OEM flexibility: Standardized dimensions and interfaces facilitate integration into multiple burner system designs.

  • Clear status indication: Multicolor LED diagnostics help technicians interpret operational and fault states quickly, aiding in maintenance and troubleshooting.
