The Siemens LMO24 Burner Control is part of the trusted LMO series, developed for automatic control and monitoring of oil burners. It manages the complete burner sequence including pre-purge, ignition, flame detection, and safety shutdown.

This controller is specifically designed for single-stage oil burners, making it ideal for applications where consistent and reliable burner performance is required.

The unit features integrated flame supervision using a photoresistive flame sensor (QRB series), ensuring that fuel is only supplied when a stable flame is present.

Built with advanced microprocessor technology, the LMO24 offers accurate timing sequences, enhanced safety features, and long-term reliability.

It is widely used in oil-fired boilers, furnaces, and commercial heating systems, providing safe and efficient burner operation.

Technical Description

The Siemens LMO24 Burner Control operates through a pre-programmed sequence managed by an internal microprocessor.

During startup, the controller initiates a pre-purge cycle to clear the combustion chamber, followed by ignition and fuel supply. The system continuously monitors the flame using a photoresistive sensor (QRB series).

If the flame is not detected within the safety time or is lost during operation, the controller immediately triggers a lockout condition, shutting down the burner to prevent unsafe operation.

The controller ensures precise timing and safe burner control, making it suitable for a wide range of industrial oil heating applications.
