Minimum ID fan speed
Lower operation point of the ID fan characteristic line.
Maximum ID fan speed
Percentage of the maximum speed that the induced
draught fan may be set to perform.
Opening of air flap at 0% control
At 0% control of the air flap, the air flap remains open by
the specified value.
Opening of air flap at 100% control
At 100% control of the air flap, this will open by the
maximum specified value.
Primary air opening at 100% control
At 100% activation of the primary air flap, this will open by
the specified value at most.
Primary air opening in pre-heating / ignition
Opening of the primary air at 100% control output.
Adjustment of the controls to fuel and various air flap
actuators or mechanical conditions.
Opening of air flap during pre-heating
In “Pre-heating” status, the air flap is opened to this value.
Opening of air flap during ignition
In “Ignition” status, the air flap is opened to this value.
Opening of air flap during shutdown
In “Shutdown” status, the air flap is opened to this value.
Opening of primary air during shutdown
Opening of primary air during boiler status “Awaiting
shutdown“.
Maximum air damper correction due to residual O2
The air damper setpoint position is changed to this
maximum extent due to the residual O2.
Minimum induced draught fan control at 0Pa
combustion chamber underpressure
If due its the load change characteristics the PI regulator
does not change quickly enough, a minimum activation of
the ID fan is calculated.
Setting - Fuel slide-in
System menu System Setting
Fuel slide-in
Slide-in control
Adjustable parameters for the fuel slide-in controller.
NOTICE!Factory setting - do not change!
Slide-in control start phase
In the first 30 minutes in the heating status, the stored
feed control value is used to limit the nominal load
operation. The function is deactivated with setting “0”.
Ratio of heating to ignition feed rate
In Heating status, the feed control value is stored in the
nominal load operation. At the next start, the ignition feed
rate is calculated and controlled via the ratio setting.
Infeed during ignition
Defined fuel feed-in for the “Ignition” status duration.
Activation delay for slide-in
Indicates the period during which the boiler approaches
the feed rate in a ramp to the feed rate in heating mode
when changing from the “Ignition” to “Heating” status.
Minimum infeed
Minimum feed rate of feed screw.
Start value of the infeed regulator
The feed controller starts at this value when the boiler
starts up.
