Setting of time of test blow-through
TEST BLOWING
ENTER < >
For boilers, at which there is tough to achieve their draught, it is recommended to increase
time of test blow-through, Pre-setting from production is for 15sec.
Setting of transition period:
TRANS. PHASE
ENTER < >
There are two parameters of transition phase: first is 14 KW and second is 30kW. Time set
by the first parameter determines, how long it will take to achieve 14kW, time of the
second parameter determines time to achieve 30kW from fire recognition.
Setting of dosing during transition phase:
TRANS. FEED.
ENTER < > EXIT
Set required amount feeded into burner after fire recognition. Feeded amount will be
gradually increased with every ration during set period. Pre-set from production is 15%
from full ration for14kW.
Time setting of cleaning by blow-through:

Setting of ash removing:
ASH AUGER

Setting of maximum burning time:
COMBUST. TIME

Setting of minimum duration of break between burn-down and ignition:
MIN. PAUSE TIME

Setting of time of blow-through clening:
MODULATION.
ENTER < > EXIT
Time of test blow-through defines time, within which will
be boiler and chimney ventilated before beginning of
EXIT
combustion (10-100 seconds).
Here you select duration from first recognizing of fire up to
feeding of full amounts of pellets adjusted by actuator
EXIT
output.
Here you can set fuel amounts that are feeded during
transition running from fire recognition until burner
achieves output of 14kW.
Cleaning by blow-through is activated, when thermostat
switches off and value recorded by photocell decreases
under 12%.
Ash removing is activated automatically in set intervals
from 1 up to 200 hours for stated period.
By this parameter it is possible to set maximum time of
continuous burner operation.
This parameter ensures, that it comes to next burner
ignition only after stated time, not immediately after burn-
down.
By the stated value of ∆T , before achieving required boiler
temperature, boiler output decreases automatically to the
pre-set level.
