Diesel Burner Controller

Product Overview

Diesel Burner Controllers are the specialized electronic "brains" designed for the automatic startup, supervision, and control of light oil (diesel) burners. These units manage the critical sequence of pre-purging the combustion chamber, activating the ignition spark, and monitoring the flame via photo-resistive sensors. Whether you are running a 1-stage, 2-stage, or modulating diesel burner, these controllers ensure high-efficiency combustion and fail-safe operation.

Key Features

Microprocessor Precision: Modern diesel controllers (like the Siemens LMO series) provide digital timing that remains stable even during voltage drops.
Integrated Oil Pre-heater Control: Supports the startup sequence for burners equipped with oil pre-heaters to ensure optimal fuel atomization.
Multicolor Diagnostics: Built-in LED indicators show the exact phase of the burner cycle (e.g., pre-purging, ignition, or flame-on) and provide fault codes.
High-Speed Flame Detection: Optimized for use with QRB... photo-resistive sensors, ensuring the fuel supply is cut instantly if the flame fails.
Undervoltage Safety: Advanced safety logic that triggers a controlled shutdown if the power supply is insufficient for safe operation.
