Burner Control Siemens LMO 24.255C2E – Microcontroller-based oil burner controls for the startup, supervision and control of forced draft oil burners in intermittent operation. Maximum oil throughput up to 30 kg/h, also above 30 kg/h on some versions. The LMO14, LMO24, LMO44 and this Data Sheet are intended for use by OEMs which integrate the burner controls in their products.
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 QRB1 / QRB3 or yellow flame detector QRB4, blue-burning flames with blue flame detector QRC1. In terms of housing dimensions, connection technology, and flame detectors, LMOs are identical to LOA burner controls.
