Siemens LMO14.111C2 Oil Burner Controller – 230V Microcontroller-Based Forced Draft Burner Control Unit

Product Introduction

The Siemens LMO14.111C2 is a microcontroller-based oil burner controller designed for startup, supervision and control of forced draft oil burners in intermittent operation. It supports 1 fuel valve stage and handles burner capacities up to 30 kg/h, compatible with QRB photo resistive detectors for yellow flames and QRC blue-flame detectors.

Featuring accurate digital signal handling and multi-color status indication, it ensures reliable operational sequences and easy fault identification. With undervoltage detection and remote reset functionality, it replaces older LOA series controllers (e.g., LOA24.171, LOA26.171) while maintaining identical housing and connection standards. Suitable for boilers, heaters and industrial combustion systems, it operates stably in temperatures from -20°C to +60°C.
