3 . T E C H N O L O G Y

Your new pellet stove is technologically
advanced as a result of years of tests in the
laboratory and in practice.
The practical advantages of your pellet
stove are convincing:
OPERATING COMFORT - OPERATIO-
NAL RELIABILITY
The electronic monitoring device together
with a patented "air sensor" controls and
regulates the interplay of flue gas fan,
conveyor auger, convection fan (optional)
and temperature.
This monitoring system guarantees an
optimum combustion and operating mode.

POWER FAILURE

After a short power failure the operating
functions that were set before the power
failure are continued.
ON mode (manual operation). The control
switches to the ST (Start Phase) and the
unit then re-runs in ON operation.
TM mode (automatic operation). The
control switches to the ST (Start Phase) and
the unit then re-runs in TM operation.
SB mode (operational readiness, standby
operation). After two seconds the control
re-runs in the SB operation.
On power failure a small amount of smoke
may be emitted. This does not last for more
than three to five minutes and does not
represent a safety risks.

OVERHEATING

A temperature safety switch (STL) switches
the stove off automatically if it overheats.
After the stove has cooled down it returns
to the regulating program.
Your operating outlay is reduced to the most
necessary - this prevents operating faults
whilst working in an optimum fashion at the
same time.
HIGHEST EFFICIENCY -
LOWEST EMISSIONS
A very large heat exchanger surface toget-
her with optimum combustion air control
leads to very good fuel usage.
Finely metered pellet feed in an optimised
burner pot made from high quality grey
cast iron effects almost perfect combustion
with very good exhaust gas values - and this
is guaranteed in every operating phase.
Whether the heating operation is conti-
nued or not depends on the remaining
embers in the fire pan. If re-ignition does
not occur when the fuel supply recommen-
ces, then the out of operation program
(cleaning , lag phase) is carried out.
According to the pre-set mode the stove
must be re-started.
CAUTION: If overheating has occurred then
maintenance or cleaning work must be carried
out.

LOW TEMPERATURE SWITCH OFF

If the stove cools down below a minimum
temperature, then the stove will switch off.
This switch off can also occur if pre-heating
is too slow.
ELECTRIC EXCESS-CURRENT SHUT OFF
The device is protected against excess
current by a main fuse (on the rear of the
device), (see "Technical Specification").
