Burner settings
Firing up
Description

Ignition test time
Time for checking if furnace is hot. Only fan is operating

Feeding time
Time for feeding fuel when firing up. It refers to the first attempt. In next
attempts the amount of fuel is smaller (20% of basic amount)

Flame detection
Threshold of flame detection in % of light, when the controller deems the
furnace as hot. It is also used for detection of lack of fuel and end of
burning off.

Firing- up airflow
% of blowing when firing up. Too big value prolongs the firing up proces
or causes failed attempt of firing up.

Firing- up time
Time of following firing up attempts (3 attempts). After that time the
controller goes to another firing up attempt.

Air flush intensity
% blower fan the flame of time has elapsed Air flush delay

Air flush delay
The time at which the fan is temporarily increased fan power to the Air
flush intensity

Worktime with min. power
Burner operation time with minimum power 30% after firing up. Power is
determined by parameter:
Blowing power 30% and feeder operation time
30% , in menu: boiler settings
–output modulation
Operation setup

Cycle time OPERATION
Time of whole fuel feeding cycle in OPERATION mode. OPERATION
mode time = feeding time OPERATION + feeder pause time

Blow-in for Min. output kW Blow-in output for minimum boiler output 30%

Feeder efficiency
Feeder fuel efficiency in kg/h

Energy density
Fuel calorific in kWh/kg.

Tank capacity
Fuel silo capacity for counting fuel level. When correct amount is put, the
user is not obliged to calibrate fuel level. The controller process this data
if calibration process of fuel level was not done. After successful
calibration of fuel level the controller does not process this value.
Burning off

Burning off maximum time
After this time the controller goes to PAUSE mode, in spite of the fact
that the controller detects flame

Burning off minimum time
Burning off will last at least this time in spite of the fact that flame sensor
indicated lack of flame

Air flush intensity
Fan power during blowing while burning off in %

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
Cleaning

Poker p. before inflame
Fan operation time during cleaning the furnace while firing up

Poker p. after bur.off
Fan operation time during furnace burning off

Cleaning airflow
Fan power in % during furnace cleaning in burning off and firing up
