Oil Burner Controls

LMO14...
LMO24...
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.
