Product Overview

The Siemens LMO14 Burner Controller for Oil Industrial Burners is a compact, microprocessor-based automatic burner control system developed for the safe startup, supervision, and shutdown of oil burners operating in intermittent mode. It is widely used with pressure-jet oil burners in industrial and commercial heating systems.

The controller manages all critical burner functions including pre-purge, ignition, flame monitoring, safety shutdown, and post-purge, ensuring reliable combustion and compliance with international safety standards. Flame supervision is carried out using a photoresistive flame detector, providing dependable detection of oil flames under demanding operating conditions.

Designed for OEM burner manufacturers, service engineers, and industrial installations, the LMO14 offers simple wiring, robust performance, and long service life, making it an ideal solution for new installations as well as replacement of legacy oil burner controllers.
