Oil Burner Controls
Microcontroller-based oil burner controls for the supervision, start-up and con-
trol of forced draught oil burners in intermittent operation. Oil throughput up to
30 kg / h with the LMO14... and LMO24..., and above 30 kg / h with the LMO44...
The LMO14..., LMO24..., LMO44... and this data sheet are intended for OEMs
which integrate the burner controls in their products.
The LMO... burner controls are designed for the start-up and supervision of single- or 2-
stage forced draught oil burners in intermittent operation.
Yellow-burning flames are supervised with photoresistive detectors QRB..., blue-
burning flames with blue-flame detectors QRC...
In terms of housing dimensions, electrical connections and flame detectors, the LMO...
are identical to the LOA... oil burner controls.
