O
2
correction
Following calibration via the output measurement or using the commissioning wiz-
ard, a new O
2
curve is generated.
The entire curve can then be moved in parallel via the
O2 total correction
at max load, thus optimising the O
2
content; the WTC drives to 100 % capacity.
Using
O2 correction up to 50%
at min load the O
2
content can also be
optimised in the lower load range.
