14.1 Boiler
Firing-up

Firing-up airflow
Airflow output durning the firing-up. Too high value slows the firing-up or causes
unsuccessful attempt to fire up.

Ignition test time
Process of checking whether the furnace is already burning. Only the fan is
running. If the appropriate exhaust gas temperature is reached, then it switches to
the OPERATION mode without the FIRE UP mode.

Ignition test time 2
Process of cheching whether the furnace is burning; this process starts when the
controller proceeds to OPERATION mode.

Feeding time
Fuel dose feeding time during the firing-up. Refers to the first attempt to fire up. In
another attempts the fuel dose is reduced.

Firing-up time
Time of a signle attempt to fire up. After this time, controller proceeds to another
attempt to fire up. After the failure of all attempts to fire up, the alarm: "Failed to
fire up" is reported.

Ex. temp. delta
Parameter defines how much the exhaust temperature must rise during the firing-
up so that the firing-up of the furnace is detected. Description in point 8.4

Ex. temp. delta 2
Parameter defines how much the exhaust temperature must rise during the test to
fire up conducted when the controller proceeds to OPERATION mode, so that the
furnance is considered fired up. Description in point 8.4

Ex.temp.at the end of fired-up
Ex. temp. above which the furnace is considered to be fired up durnig the ignition
test or firing-up. Description in point 8.4

Test dose
Fuel dose (feeding time) that is going to be fed during the ignition test before
proceeding to FIRIE-UP mode.
Output modulation Menu includes settings of burner for different output levels.
Burning off

Buring off time
After this time, will be enter the STOP mode even though the exhaust
temperature sensor indicates the presence of a flame.

Air flush intensity Blow-in output during burning off.
Supervision

Supervision time
It is the max. time over which the regulator remains in SUPERVISION mode. If
there is no need to start heating again within this period of time, the regulator
automatically proceeds to burning-off mode. Setting thi
s parameter at „0” disables
SUPERVISION mode, and regulator proceeds directly from OPERATION to
BURNING OFF mode.

Feed time
It is the time of fuel feeding and fan operation in SUPERVISION mode. Setting
this parameter at „0” causes that only fan will be ON in SUPERVISION mode.
Value of this parameter may not be too high because it may lead to boiler
overheating in SUPERVISION mode. In SUPERVISION mode, boiler temperature
must slowly drop.

Feed interval
It is the time of fuel feeding interruption in SUPERVISION mode. Value of this
parameter may not be too small because it may lead to boiler overheating in
SUPERVISION mode. In SUPERVISION mode, boiler temperature must slowly
drop.

Airflow oper. Extend.
In SUPERVISION mode of boiler operation, once the fuel dose has been supplied
and the feeder stopped, the fan remains in operation for a time set in
Airflow oper.
extend. to fire-up the fuel dose supplied.
Setting this parameter at "0” causes the
fan to be OFF in SUPERVISION mode. Value of this parameter may not be too
high because it may lead to boiler overheating in SUPERVISION mode. In
SUPERVISION mode, boiler temperature must slowly drop.
Lambda sensor Description in point 18

Operation with Lambda sensor Turns off and on the operation of Lambda sensor.

Airflow correction range
Defines the acceptable airflow range variation during the operation using Lambda
sensor.

Feed lock Description in point 18

Fuel detection - oxygen
