
Feed time
Feed time in SUPERVISION mode; too high value may cause the boiler
to overheat or fuel over-filling; too low value results in fuel returning to
the container.

Interval time
Feeder work cycle time in Supervision mode. SUPERVISION cycle time
= feed time + interval time

Fan time extension
In SUPERVISION mode, after a fuel dose is supplied and the feeder is
off, the continues to work for the extension period in order to ignite the
fuel dose. This parameter should not be set too high as it may over heat
the boiler.
Min. fan speed
Minimal fan speed in % that can be selected by the user of the regulator.
This parameter is used to limit the access to the complete fan speed
range in the user menu. It is not used in the fan control algorithm. The
parameter should be set relatively low, allowing the fan to spin slowly
and freely.
Lack of fuel detection time
Lack of fuel detection time is deduced after the exhaust temperature
drops below the
Lack of fuel detection threshold. After this time is
deduced, the regulator makes 3 attempts to ignite the burner, and when
this fails, it displays the “ignition failed” alarm.
Exhaust temperature when no
fuel
If exhaust temperature is lower than this value for a time longer than the
time set in the
Fuel lack detection time parameter, lack of fuel will be
detected and next firing-up attempt will be made.
Exhaust temperature increase
time
This time is used as function preventing the extinguishing of flame in
OPERATION mode. If the exhaust temperature does not exceed the
Lack of Fuel Detection threshold after such time, an ignition test will be
made.
Exhaust temperature - blow
reduction Exhaust temperature over which revolutions of the fan are reduced
(down to a minimum power).
Max. feeder temp.
This parameter determines the maximum temperature at which the alarm
for exceeding the maximum feeder temperature is displayed. When this
temperature is exceeded, the feeder is engaged for a predefined time,
with a several-minute pause. If the temperature drops, the regulator
resumes normal operation; if not, the feeder will be engaged for a longer
period in order to remove embers from the feeding pipe. These times
may be edited in a special menu accessible only to the manufacturer of
the boiler.
Feeder 2 operation time Additional (external) feeder operation time.
14.2 BOILER
Grate

Max. ignition time
When this time is exceeded ant the exhaust temperature does not rise
above the Lack of Fuel detection thr15°C, a failed ignition alarm
will be displayed. Note: during ignition in RUST mode, the fan works at
the
Ignition fan - grate speed. This parameter is adjusted via the user
menu.

Lack of fuel detection time
Time is counted after fumes temperature drops below the Fuel detection
threshold value. In the grate mode, blow operation is stopped. If the
burner is active, flame test is started. Lack of fuel detection is off for "0"
setting.

Lack of fuel detection method
Only exhaust - lack of fuel detection occurs via the indications of the
exhaust temperature sensor. This method allows to detect the lack of
fuel quickly. It can only be used when there is an exhaust sensor in the
flue of the boiler.
Water and exhaust - lack of fuel detection occurs both via the indications
of the exhaust temperature sensor and the water temperature sensor in
the boiler. To detect the lack of fuel, both temperatures need to drop,
and the water temperature in the boiler must drop below the
CH pump
activation temperature .

Boiler hysteresis
If boiler temperature goes below preset temperature by value of boiler
hysteresis, then automatic firing-up of burner takes place.

Purge operation - supervision
Fan purge time when the boiler temperature exceeds the boiler’s set
temperature

Purge interval - supervision
Fan purge interval time when the boiler te
mperature exceeds the boiler’s
set temperature
