
Air flush period
Duration of blowing when burning off fuel and burning off

Air flush interval
Break between airflows while burning off the fuel in burning off process

Air flush start
Flame brightness with which airflow starts while burning off the fuel

Air flush stop
Flame brightness with which airflow starts when burning off the fuel in
burning off process

Exhaust fan
% of the exhaust fan blowing rate during the ignition. Excessive value
will make the ignition process longer or result in a failure to ignite the
fuel.

Vacuum
Preset value of the vacuum in the combustion chamber during the
ignition.
Cleaning

Firing up cleaning time
Fan operation time during cleaning the furnace while firing up

Burning off cleaning time
Fan operation time during furnace burning off

Cleaning airflow
Fan power in % during furnace cleaning in burning off and firing up

Exhaust fan
% of the exhaust fan blowing rate during the ignition. Excessive value
will make the ignition process longer or result in a failure to ignite the
fuel.

Vacuum
Preset value of the vacuum in the combustion chamber during the
ignition.
Supervision

Boiler power
Boiler power in the SUPERVISION mode.

Supervision time
After this time, when the controller is in SUPERVISION mode, the
controller automatically starts burner burning off. By settings = 0,
SUPERVISION mode is deactivated.
Grate

Flush time SUPERVISION
The duration of the fan blow in the supervision in grid mode

Flush period SUPERVISION
Interval between blows in the supervision in grid mode
Lambda probe
Operation with Lambda probe
If the parameter is set to "ON", the controller will operate using the
lambda probe readings. The amount of air supplied to the furnace will be
adjusted automatically to maintain the preset oxygen content in the flue
gas. If the parameter is set to "OFF", the lambda probe readings will
have no influence on the operation of the controller.
Dynamics
It has an impact on the rate of the adjustment of oxygen content in the
flue gas to reach the preset value and on the stability of the oxygen
content in the flue gas. It is not recommended to modify the parameter if
the adjustment time and the stability of the preset oxygen content are as
required.
Response time
It has an impact on the rate of the adjustment of oxygen content in the
flue gas to reach the preset value and on the stability of the oxygen
content in the flue gas. It is not recommended to modify the parameter if
the adjustment time and the stability of the preset oxygen content are as
required.
Blowing correction range
Defines the allowed range for the blowing rate variability when operating
with the lambda probe.
Other
Min. blowing rate
Minimum blower power in % selectable by the controller user. It is used
only to limit the available blower power range. It is not used for the
blower control algorithm and should be as low as possible to ensure slow
and smooth blower rotation without "buzzing".
