Our products are manufactured in accordance with the essential requirements of the various applicable guidelines.
They therefore carry the -label and are supplied with all the required documentation.
Technical details subject to change.
We as the manufacturer cannot be held liable in the following cases:
– Incorrect use of the unit
– Failure to perform proper maintenance
– Incorrect installation of the unit
1.1.2 Installer’s obligations
The installer is the person responsible for installing the unit. The installer must comply with the following instruc-
tions:

1.2 Safety precautions
The boiler and related accessories are state of the art and meet all applicable safety regulations and operate
using 230 V AC electrical current. Improper installation or repair can pose the danger of life-threatening electrical
shock. Installation may be performed only by appropriately qualified technicians.
Caution symbols
Please take careful note of the following symbols in this Operating Manual.
1.3 Sources of danger
1.3.1 Power failure (or if the blower is not running)
Attention!
Do not open the combustion chamber door, there is an increased risk of deflagration when opening
the combustion chamber door. A self-test is performed following a power failure during combustion
and then operation is continued automatically.
1.3.2 Burner pot
Attention!
Never fill the burner pot with pellets by hand. Excessive combustion material in the burner pot me-
ans that the pellets will not be ignited optimally. Too much low temperature carburisation gas will
be generated and this can lead to deflagration.
Please note: Risk of crushing from rotating auger.
If you have to touch these parts, always deenergise the boiler.
Warning of hot surface: risk of burns!
Before touching these surfaces, you must switch off the boiler and let it cool.
Attention!
Ignoring the warnings identified can lead to personal injury.
Information!
Ignoring the warnings identified can lead to malfunction of, or damage to the boiler or heating
system.
Note!
The blocks of text highlighted provide information and tips for operation.

1.3.3 Entering the pellet storage room, storage container
All energy sources are subject to safety regulations which must be observed when working with fuels, heating
systems and storage rooms. This also applies to the storage of pellets.
After the storage room is filled, odourless carbon monoxide (CO) may be produced and there may be insuffici-
entoxygen. For this reason, do not enter the pellet storage room for 6 weeks after it has been filled. Only trained
persons may enter the storage room for the purpose of measuring gas levels.
Please also follow the instructions on the sticker:
– No access to unauthorised persons, keep children away from the pellet store!
– Ensure sufficient ventilation before entering. Keep the door open while inside.
– Only enter the storage room under the supervision of a second person standing outside.
– No smoking, flames or other sources of ignition are permitted.
– Risk of injury from moving parts.
– Pellet boilers must be switched off at least 15 minutes before filling.
– Fill in accordance with the instructions of the boiler and pellet suppliers.
– Protect pellets from damp.
If you feel unwell, leave the storage room immediately and seek medical advice.
Attention!
Do not attempt to enter an unaired storage room (particularly buried tanks).
1.3.4 Combustion air
Never seal openings that have been provided for letting air in and out!
1.4 Fuel
To ensure that your new heating system provides long-term reliable service, the following must be observed:
Quality of pellets must be in accordance with EN 14961-2 A1:
The quality of the pellets is an important factor in achieving optimum operation of the heating system. When bu-
ying pellets, make sure that they meet the quality standards of EN 14961-2 A1 (or ÖNORM M7135 / DINplus). For
maximum reliability, source pellets from manufacturers with EN-Plus certification (or DIN-Plus, ÖNORM M7135
or UZ38), as they are required to perform ongoing internal quality control.
Diameter: 6 mm; Length: 80% between 15 – 30 mm and 20 % up to 45 mm
Make your pellet supplier aware of these quality requirements before ordering and seek confirmation upon
delivery.
Consequences of quality fluctuations:
Pellets are 100% unprocessed wood, so minor fluctuations in fuel quality are normal and reflect the natural ori-
gins of the material. These quality fluctuations affect the level of dirt, the ash content and therefore the cleaning
intervals.
A reduction in cleaning intervals due to fluctuations in pellet quality cannot be remedied as part of a repair under
guarantee!

1.5 Start-up and maintenance
Please permit Windhager Customer Service or have one of our customer service Partners put your new boiler into
service. In this way, all functions of the new unit will be thoroughly checked; you will also benefit from the detailed
information provided by the system installer. Installation by a qualified technician as well as the maintenance
required by the guarantee limitations and undertaken by Windhager Customer Service or a customer service
partner will guarantee the optimal use and service life of your boiler system. This is the only way to assure the
benefits of this technologically advanced boiler and guarantee safe, environmentally friendly and energy-saving
system operation.
The following preconditions must be met before you order the initial start-up:
1.) Boiler installed correctly.
2.) System fully wired up electrically.
3.) System rinsed, filled and vented – heat consumption must be possible.
4.) Boiler connected to domestic water and filled.
5.) Sufficient quantity of fuel available (pellets, split logs, oil or gas).
6.) The customer must be present during start-up.
The initial start-up cannot be carried out if any of these points are neglected. The customer will be charged for
any unnecessary costs arising as a result.
Start-up and maintenance by Windhager Customer Service or a customer service partner are part of the gua-
rantee requirements of the enclosed “guarantee limitations”.
Note!
During the first few weeks after start-up, condensation can occur in the combustion chamber, ash
pan and on the heating surfaces. This has no effect on the function and service life of the boiler.
1.6 Functional test
EN 12828 and ÖNORM B8131 require that the function of the system and related safety equipment be checked
and certified yearly by a qualified technician (installer, heating system contractor).
At two-year intervals, the heating water condition must be checked (ÖNORM H 5195) by a heating expert (installer)
(see BioWIN assembly instructions – Heating water); this is to prevent corrosion and sediment accumulation in
the heating system and boiler. For systems using more than 1,500 litres of water (e.g., systems with accumulator
tanks), this inspection is required on an annual basis.
In the event of repair work requiring a change of water in the heating system, the heating water is to be checked
within 4 to 6 weeks after such work.
Corrosion and sediment resulting from improper heating water are not covered by the guarantee and warranty.

1. Important information for system operators
Pressing one of the six buttons firstly switches just the lighting and display on. The boiler is only switched off
when the button is pressed for the 2nd time. Wait until burnout mode has finished (not indicated on the display)
and open the combustion chamber doors.
During filling, negative pressure is created in the pellet store and this can cause burn-back in the pellet boiler.
Therefore, the boiler must be stopped from operating during the filling procedure.
Attention!
The pellet flue-connected stove must be switched off correctly at least 15 minutes before the store
is filled – Fig. 2. Press the ON/OFF button. Never switch off using the emergency OFF switch!
Tip!
To prevent negative pressure arising in the pellet boiler, open the combustion chamber door (see
Fig. 3 and also section 2.1) and leave open during the filling process.

2.2 Functional description, function elements and
operating controls
The BioWIN 2 pellet boiler and the Modular Energy System MES or the REG standard control combine to form a
perfect unit. The BioWIN 2 automatically fires when the control system signals a heating requirement. Following
“purging” (safety function), ignition starts and the pellet metering auger switches on. The burner pot is automati-
cally filled with pellets. When flame formation has been detected (thermocontrol sensor), the boiler enters flame
stabilisation mode and then control mode (modulation mode) and keeps to the specified boiler temperature set-
point. The boiler enters burnout mode if the heat consumed drops below the minimum nominal thermal output or
no heating requirement is signalled by the control system. The blower continues to run until the burner pot has
cooled down.
2.2.1 BioWIN 2 Klassik
The reserve supply container is loaded by hand. The heating surfaces are cleaned manually using the cleaning
lever. The cleaning residues from the heating surfaces and the combustion residues from the burner pot drop into
the ash pan. In the event of cleaning request, the ash has to be removed by hand.

2. Operation
2.2.2 BioWIN 2 Premium
Version as BioWIN Klassik, but in addition with fully automatic pellet feed
The pellet feed uses a maintenance-free suction turbine to fill the BioWIN 2 reserve supply container fully auto-
matically with pellets from a pellet storage room or storage container. The pellet feed is switched on by the lower
fill level switch (proximity switch) in the reserve supply container or at the end of the enable time or the beginning
of the start time, and runs for as long as the reserve supply container is full. Filling is not started if the boiler is
in heating operation or the feed has been blocked by the control unit (not during the enable time e.g. at night). If
the boiler is operating when filling is necessary, the boiler switches to burnout mode.
When there are several suction probes, switching to the suction probes is executed automatically. The system
changes to the next suction probe after the reserve supply container has been filled a certain number of times.
This means the storage room is evenly emptied to a large extent.

2.2.3 BioWIN 2 Exklusiv
Version as BioWIN 2 Premium, but in addition with fully automatic heating surface cleaning and ash
removal
Fully automatic ash removal:
During fully automatic ash removal, the ash is transported out of the combustion chamber and the heating sur-
faces in the side ash container under the supply container using a motor and auger. Pellets only have a low ash
content (approx. 0.5 %). The container therefore only needs emptying 1–3 times a year.

2.6.4 Solid fuel / buffer mode
If the BioWIN 2 pellet boiler is combined with a solid fuel boiler or an accumula-
tor tank, the WVF or B-PLM module integrated in the control panel automatically
switches over between pellet and solid fuel/buffer mode.
Combustion of the BioWIN 2 is stopped when the WVF or B-PLM module sends
the request to switch over to solid fuel/buffer mode – Fig. 18.
Following this, the system switches over to solid fuel/buffer mode and the Bio-
WIN 2 burner is locked – Fig. 19.
If the pellet boiler is switched off using the ON/OFF button on the InfoWINplus,
an automatic switchover to solid fuel/buffer mode is performed in conjunction
with a WVF module. Once the InfoWINplus unit is switched on, the pellet boiler
can be locked out for a maximum of 15 minutes due to switch-over delays. This
is displayed by InfoWINplus – Fig. 19.
After an hour in solid fuel/buffer mode, the display is shut down fully, only the
green LED is lit up. The display is switched back on by pressing a button or when
there is a heating requirement.

2. Operation
2.6.5 Manual operation
Note!
Manual operation cannot be started in “solid fuel/buffer
mode”. Manual operation must not be started if an ins-
talled solid fuel boiler is operating (heated up). Manual
operation may be started if there is no solid fuel boiler in-
stalled or if this is not operating but only the accumulator
tank is active. In this case, first set the operating mode
switch on the WVF+ to relay test 2 or on the B-PLM+ to
relay test 1 (see WVF+ or B-PLM+ operating manual).
Pressing one of the six buttons switches the lighting
and display on. Manual operation starts if the Manual
operation/chimney sweeper function button is pressed
for more than five seconds – Fig. 20. This sets the boiler
temperature to the setpoint fixed for manual operation
(standard value 60 °C). The current automatic setting
is not affected by this (see also section 2.10). The ligh-
ting is switched off after the lighting timer has counted
down (10 minutes); the function or display remains un-
changed.
Pressing the Cancel button terminates the function –
Fig. 21. The boiler returns to automatic operation.
Setpoint adjustment for manual operation
By pressing the – or + button the display switches to
the setpoint adjustment mode – Fig. 22. Using the – or
+ button can change the setpoint in 1 K steps. The tem-
perature set in this mode is not permanently saved. The
original set temperature is used once manual operation
ends.
After pushing the Back button (Fig. 23) or after waiting
10 minutes, the screen returns to its previous display.

2.6.6 Chimney sweeper function
This function aids the performance of legally-required
emissions testing.
Note!
The chimney sweeper function cannot be started in “solid
fuel/buffer mode”. The chimney sweeper function must
not be started if an installed solid fuel boiler is operating
(heated up). The chimney sweeper function may be star-
ted if there is no solid fuel boiler installed or if this is not
operating but only the accumulator tank is active. In this
case, first set the operating mode switch on the WVF+ to
relay test 2 or on the B-PLM+ to relay test 1 (see WVF+ or
B-PLM+ operating manual).
A short press of the Manual operation/chimney
sweeper function button switches on the lighting and
display. Pressing the button again starts the chimney
sweeper function – Fig. 24. The boiler temperature is
set to approx. 60 °C for 45 minutes.
Pressing the corresponding button enables the boiler
to be operated with 30 % or 100 % output – Fig.25. The
lighting is switched off after the lighting timer has coun-
ted down (10 minutes); the function or display remains
unchanged. Only the lighting is switched on when the
button is first pressed.
The operating time is reset to 45 minutes. when the
Manual operation/chimney sweeper function button is
pressed again.

me stabilisation.
2.7.4 Flame stabilisation
Following the ignition procedure, even combustion is established and then the
system switches over to modulation mode.
2.7.5 Modulation mode
The burner is in modulation mode. The output is infinitely varied between 30 %
and 100 %.
2.7.6 Burnout
Combustion is stopped. Pellet transport into the burner pot is stopped, the In-
duced draught fan continues to run until all the remaining pellets have been
burned and the burner pot has cooled down.
2.7.7 Burner OFF
There is a heating requirement from the control system, but the boiler tempe-
rature (actual value) is higher than the boiler temperature setpoint. This means
combustion is stopped and the burner is switched off.
