LMO44...
Microcontroller-based oil burner controls for the startup, supervision and control
of forced draft oil burners in intermittent operation. Standard versions with an oil
throughput up to 30 kg / h, special versions above 30 kg / h.
The LMO14..., LMO24..., LMO44... and this Data Sheet are intended for use by
OEMs which integrate the burner controls in their products.
Use, features
The LMO... are designed for the startup and supervision of 1- or 2-stage forced draft oil
burners in intermittent operation. Yellow-burning flames are supervised with photo
resistive detectors QRB..., blue-burning flames with blue-flame detectors QRC...
In terms of housing dimensions, electrical connections and flame detectors, the LMO...
are identical with the LOA... oil burner controls.
