8  Selection of operating mode 
 
To facilitate straightforward adaptation of the LMV37.4 to different types of burners, the 
LMV37.4 offers automatic configuration of the operating mode. This means that – 
derived from parameter 201 – the most important settings relating to the operating mode 
are made automatically. Very often in that case, the only manual settings to be made 
are those for the fuel-air ratio control system. After selection of the operating mode, 
parameters that are not required will be hidden (e.g. oil parameters when firing on gas).
