The calibration data of the Lambda probe will be deleted
and set to the default value (21% oxygen = 10 V at
analogue input).

Ignite
Infeed time without ignition
During this time the boiler attempts to go to “heating”
status by feeding material without activating the ignition. If
the criteria for “heating” status are not reached within this
time, the ignition starts ("Ignition on w/o feed” parameter).
Ignition on w/o feed
If the boiler does not reach “heating" status within a
defined time (“infeed time without ignition” parameter),
material infeed will be stopped for this set time period so
that the boiler does not become overfilled with fuel. During
this period the boiler has time to ignite the material that
has already been brought in, before changing to the actual
ignition procedure. This is generally shortened by the
preheating phase.
Infeed during ignition
Specifies the infeed during ignition as a percentage of the
specified maximum infeed.
Maximum ignition duration
If the boiler does not meet the criterion for heating mode
within this time (“Boiler - flue gas temperature difference”
parameter), the “Ignition attempt unsuccessful” error
message appears.
Ignition fan run-on
Specifies the run-on time of the ignition blower in seconds
after the ignition heating is switched off. If the run-on time
is set to 0 seconds, the ignition blower fan is constantly
active. In this case the blower fan is only switched off in
operating statuses case cooling, off, standby and in the
event of a fault.
Maximum temperature drop during heating
If the CCT decreases by this value when heating starts,
the ignition fan is activated again. This parameter is
enabled until the minimum CCT is reached.
Use forced ignition
Specifies whether the forced ignition should be used.
When switching to “Heating” mode, the ignition remains
active either until the set time has elapsed or the specified
combustion chamber temperature has been reached.
Maximum duration of forced ignition
Specifies the run-on time of the ignition after the operating
status has changed to "Heating". The ignition remains
active either until this time has elapsed or until the
specified combustion chamber temperature (“Maximum
duration of forced ignition” parameter) has been reached.
Forced ignition off at CCT
Specifies the combustion chamber temperature in °C from
which forced ignition is switched off before the set runtime
elapses (“maximum duration of forced ignition” parameter).
