NOTICE!
When switching on any O
2
correction you must ensure, that the combustion boundary values
are maintained even with the maximum possible correction (100%). For details see chapter
6.11.6 Checking the Combustion Boundary Values.
Correction type 2 is used where the correction is applied to a non-linear control element, e.g.
air damper. The curve's slope is taken into account before calculating the correction. A flatter
curve results in a smaller correction range, whilst a steeper curve results in wider range.
