Metering signal
This parameter is essential for setting up the combustion air.
If this value is increased, more pellets are fed into the burner
(less O2 in the exhaust gas). If this value is reduced, fewer
pellets are fed into the burner (more O2 in the exhaust gas).
The value is adjusted proportionally for all output settings.
For this reason, it may only be changed by a specialist using
measurement equipment!
