6 Commissioning
If the correction is applied to a fuel actuator, the effect is reversed so that 0% corresponds to
the smallest target value. By using the spread factor held in parameter 433 - Commissioning
level - the correction effect can also be weighted across the burner's output.
For details see commissioning manual under Help P 30.
