10 Appendix
– Adjust setpoint value of the three-point step channel in the air deficiency direction (for
dead band setting, see parameters)
– Reset setpoint value to original value
– Run all channels this way in succession to the limit at the various firing rate points
– normally at low, medium and high fire
– Repeat this for all relevant operating modes (curve sets).
WARNING!
If applicable, perform the test which is described above in the air deficiency direction rather
than in excess air direction unless it is ensured that the flame is stable and there would be no
excess CO at the limits, which are set in the excess air direction.
