Selection of operating mode
To facilitate straightforward adaptation of the LMV27 to different types of burners, the
LMV27 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 air-fuel 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).
