FUNCTIONAL DESCRIPTION

Heating with the Ariterm Biomatic+ 20
many ways. The main difference is that heating with solid fuel produces a certain amount
of ash, which must be removed at certain intervals. If the ash is not removed, combustion
efficiency will decrease and the burner may malfunction.
The integrated pellet burner of the Biomatic+ 20
but can if necessary be manually ignited. The electric ignition system of the burner will only
be activated during cold starts, i.e., when the system has been inactive for a long period
and the boiler temperature has dropped to at least 7 ˚C below the target temperature.
During operation, if not de-activated, the necessary ignition take place by means of the
embers in the burner head, i.e. a warm start. This saves electric energy.
The burner and the internal feeding system operate automatically. The operation of the
burner is controlled by the temperature sensor installed in the boiler. The burner head is due
to the true lambda control fed with an accurately defined mixture of fuel and air for optimal
combustion, which is both cost-effective and environmentally friendly.
The burner auger is over-pressurised during operation. The purpose of this is to reduce
the risk of damage to the burner if the draught is weak.
The automatic heat regulation system adjusts
the supply water temperature according to the
outdoor and indoor temperature.
Wood pellets according to EN standards
with a diameter of 6 or 8 millimeters are the
recommended fuel for the boiler.
The convection parts of the boiler is
automatically cleaned on set intervals.
Ash is to be removed from the ash box
located in the lower part of the boiler.

SAFETY AND ALARMS

For safety reasons, the Biomatic+ 20
other to prevent possible damage. Any malfunctions or damages caused by incorrect
handling will then be limited to the burner. The fuel store must be built as a separate,
fire-classified, confined space.
Faults that cause the system to stop are indicated by a red indicator light. In addition to this,
a text message appears in the web app and an email will be sent if the boiler is connected
to internet AND email addresses are added in menu "Alarm: Manage emails".
During every operating cycle of the external feeding system, a small amount of pellets is fed
from the pellet store to the upper connection of the burner. To allow dispense of an accurate
and equal amount of pellets during every operation cycle of the burner, the feeding is carried
out by means of a separate internal feed system - including feeder screw, locker feeder and
burner screw - to the burner head.
As the internal burner screw feeds pellets forward three times faster than they arrive at the
screw, a safety zone, containing only single pellets, is created between the burner head and
the upper connection. This safety zone always remains intact even in the event of power
failure, insufficient maintenance or equipment breakage.
Alarms are described in "Alarms and troubleshooting".
The external feeding auger must be installed in
such a way that its position, with respect to the
drop funnel, allows the drop pipe to swing free
outside the burner in case of back fire.
