Adjustable Parameters - Lambda values
Parameter
Description
Residual oxygen content
setpoint 8.0%
The air dampers are regulated according to this target value.
Residual oxygen content,
above which it switches
to SHUTDOWN 19.0%
If the residual oxygen content in flue gas exceeds this value during
“Heating” mode, and the value “maximum heating up time” (see
Adjustable Parameters - Flue Gas) has elapsed, the Boiler Control
System switches to “Off” mode.
Calibrating the Lambda Probe
Calibrating the Lambda should be performed before initial start-up.
Boiler doors must be open and Lambda Probe activated.
 See section 5.7.1 for Lambda probe activation
