CAUTION!
On non-compliance withthis safety instruction, there is
a risk of material damage.
WARNING!
On non-compliance withthis safety instruction, there is
a risk of physical injury.
DANGER!
On non-compliance withthis safety instruction, there is

1.3 Warranty, guarantee and liability
Requirements
We can only accept liability for the function of our
products if they are correctly installed and operated.
This is only possible if the conditions below are
complied with.
Maximum of 2,000 hours at full load per year
The boiler described in this user manual may only be
used for heating and producing hot water, with no more
than 2,000 full-load hours annually.
Installation in a dry room
For set-up, a dry room is required. In particular, only
condensation dryers may be used as clothes dryers in
the same room.
Observe local building and fire safety regulations
Local building and fire safety regulations must be
observed.
Connecting pipe to chimney
The connecting pipe to the chimney must be a
moisture-resistant stainless steel flue pipe with
maximum diameter of 120 mm and at least 3 cm of
insulation. For lengths over 2 m, correspondingly more
insulation is needed.
Suitable fuel
The boiler is suitable for use with wood pellets
according to EN ISO 17225-2:2014, quality class A1,
ENplus-A1. Operation with unsuitable fuels, in
particular those containing halogens (chlorine) or high-
slag pellets such as from grain waste, is not permitted.
Ensure supply air is free from aggressive
substances
The air supplied to the boiler must be free from
aggressive substances such as chlorine and fluorine
from solvents, cleaning agents, adhesives and propel-
lants, or ammonia from cleaning agents, to prevent
corrosion of the boiler and chimney.
Permissible water hardness
Water is the intended heat-transfer medium. For
special anti-frost requirements, up to 30% glycol may
be added. Softened water is required for the initial fill-
up of the heating system and for refilling after repairs.
Addition of hard water should be minimised to limit
limescale build-up in the boiler.
In order to protect the boiler from calcification, the
water hardness of the heating water must be
taken into account. Observe the indications outlined in
ÖNORM H 5195-1. Details can be found inchapter 8.1
"Water hardness".
pH value between 8 and 9
The pH value of water used to fill the heating system
must be between 8 and 9.
Use a sufficient number of shut-off valves
Set enough shut-off valves to avoid bleeding large
amounts of water during repairs. Any leaks in the
system must be repaired at once.
Sufficiently large expansion tank
To protect against air suction if the system cools off, a
specialist must design a sufficiently large expansion
tank. The 18-litre expansion tank built into the boiler is
sufficient for typical underfloor or radiator systems. If
there is a buffer storage tank, an additional expansion
tank will be needed.
Sufficient air venting must also be ensured. Open
expansion tanks or underfloor heating with permeable
piping also have a high air intake, resulting in above-
average boiler corrosion. Corrosion damage to the
boiler due to insufficient air venting or high air intake is
excluded from warranty, guarantee and liability.
Sufficient power
Continuous operation with heat consumption below
the minimum specified on the type plate is only
permitted with a buffer storage tank of sufficient size.

General Warranty, guarantee and liability
7
Expanding the control system
Only components provided by us may be used for
expanding the control system, unless these are
generally available standard devices, such as thermo-
stats.
Regularly perform cleaning and maintenance
Cleaning and maintaining the product is essential. The
required steps andintervals are either contained in this
documentation or included as a separate document.
Repairs
Repairs are only permitted using spare parts provided
by us. The only exceptions are common standardised
parts such as electrical fuses or fastening materials, as
long as they possess the required features and do not
restrict the functionality of the system.
Proper installation
The installing contractor is liable for proper installation
according to the corresponding installation instructions
and the relevant rules and safety regulations. If you as
customer have installed the heating system partly or
entirely without relevant training and in particular
without up-to-date practical experience, without having
the installation checked by a trained and responsible
expert, we exclude defects in our delivery and conse-
quential damages resulting from this cause from our
warranty, guarantee and liability.
Repair of defects
For repairs of defects carried out by the customer or by
a third party, ETA shall only bear the costs or remain
obligated by warranty if this work was approved in
writing in advance by the customer service of ETA
Heiztechnik GmbH.
No tampering with boiler safety devices
Boiler safety devices such as those mentioned below
must not be tampered with: Temperature monitoring
and control devices, safety temperature limiters, safety
valves and thermal discharge valves.

Explanation of the maintenance switch
The maintenance switch on the boiler is needed for
performing maintenance with the aid of the [Main-
tenance] function in the ETAtouch control system. This
displays the individual maintenance steps on the boiler
screen.
With this variant the heating mode is stopped, but
the boiler remains on at the mains switch. So that
all drives are disconnected, the safety chain of the
boiler is disrupted with the maintenance switch. The
screen will display amessagewhen it istimetoactuate
the maintenance switch.
Fig. 2-1: Maintenance switch
The maintenance switch is marked with the
symbol and has two settings.
•"1" = regular operation
This is the standard position of the maintenance
switch. The boiler can execute heating mode in this
position.
•"0" = maintenance mode
In this position, all drives are disconnected to
perform maintenance. The circuit boards,
however, are still live.
Display maintenance steps on the screen
With this boiler, the maintenance steps can also be
displayed on the ETAtouch control system screen.The
required activities will be explained to you step-by-step
and supplemented with detailed graphics. Each
maintenance is saved andthe details can be viewed at
any time. So you can maintain a long-term overview of
the maintenance carried out. Of course, the
maintenance can also be carried out using the service
guide, without the support of the ETAtouch control
system.
To access maintenance, switch to settings in the boiler
function block ( [Settings] button) and then select
the function [Maintenance].
Fig. 2-2: Overview (example)
You can also access this overview by pressing
the maintenance switch.Also when the message
appears that maintenance of the boiler is required.
In the overview the different maintenance intervals are
listed in the upper area. This includes the maintenance
already carried out. With the button, information
about the selected maintenance is displayed.
Maintenance that you can carry out as an end
customer is labelled with the symbol.All others are
reserved for specialists and require authorisation.
Press the button to start the maintenance. The
individual steps are displayed on the screen. You can
switch to the next or the previous screen respectively
with the arrow keys on the left and right side of the
screen.
Fig. 2-3: Maintenance step (example)

10 www.eta.co.at
Description
Follow the on-screen instructions and carry out all
steps carefully. Enter your name at the end of
maintenance ( button) and save the maintenance
with the button.
Fig. 2-4: End of maintenance
To end maintenance prematurely, press the right
arrow key several times until you get to the end.
There you can end the maintenance with the
button. Cancellation during a maintenance step is not
possible.
Adjust the hinges for the screen
The ease of movement of the hinges to swivel the
screen can be adjusted with the Allen key supplied. If
the screen does not remain in its desired position,
tighten the screws on the hinges a little.
Fig. 2-5: Hinges
Clean panels
If necessary, clean the panels of the boiler and the
ETAtouch screen with a moist cloth.
Under no circumstances use aggressive
solvents, chemicals or scouring agents. They can
lead to stress cracks and damage.
Protection function for drives and pumps
Lets you switch on the boiler in summer, or
outside the heating period on the main switch.As
the ETAtouch control system starts some drives and
pumps for a short time at regular intervals so that they
do not seize in the event of a longer standstill.
If the boiler is switched off for a longer time on the
mains switch, then this protection function is missing.
Drives or pumps could then seize and cause faults
when being switched back on.

3.1 General information
Operation only by trained personnel
The product may be operated by trained adults only.
Training may be provided by the heating technician or
our customer service. Please read the associated doc-
umentation carefully in order to avoid errors during
operation and maintenance.
Persons who lack experience and knowledge as well
as children may not operate, clean, or maintain the
product.
Keep children away from the pellet store
Children must be kept away from the pellet store. It is
a good idea to lock the door to the pellet store. The
door handle on the inside of the pellet store must not
be removed. It must be possible to open the door from
the inside in an emergency.
Keep fire extinguishers in a clearly visible location
In Austria, the minimum requirement is an
ABC powder extinguisher with 6 kg.AnAB foam extin-
guisher with 9 litres, which produces less damage
when used, is preferable. The fire extinguisher should
be kept outside the boiler room, visible and easily
accessible.
Fig. 3-1: Fire extinguisher
In Germany and Switzerland, fire extinguishers are not
required for heating systems in private residences. In
spite of this, we recommend having one in the house.
Storage of ash
The ash must be kept in non-flammable containers
with covers for cooling. Never put hot ash into the
waste bin!
Emergency stop switch for the boiler
In Austria, heating systems installed in boiler rooms
must be equipped with an emergency stop switch.The
switch must be situated immediately outside the
access door and clearly marked. For boiler rooms that
are only accessible from outdoors, these switches may
also be within the boiler rooms, immediately next to the
access doors.
Fig. 3-2: Emergency stop switch
A single-pole emergency stop switch is integrated into
the boiler's safety chain. When actuated, it interrupts
the supply of combustion air and fuel. The pumps
continue running to cool the boiler.
3.2 Safety devices
Pump safety run, automatic heat dissipation at
overtemperature
If the boiler temperature exceeds 90°C (factory setting)
for any reason, the pump safety run will start. All
heating pumps and boiler pumps that are connected to
the boiler control system are switched on to dissipate
heat from the boiler.
This action prevents the boiler temperature from rising
further and triggering further safety devices such as
the safety temperature limiter.

Safety devices Safety
Heat dissipation is limited by the selected
maximum flow temperature in the heating circuits
and the target hot water temperature.
Safety shutdown by safety temperature limiter
For additional safety against boiler overheating, a
safety temperature limiter is built into the boiler. When
a boiler temperature of 100 °C (tolerance +0°/-6 °C) is
reached, the power supply to the draught fan and the
fuel intake is interrupted. When the boiler temperature
decreases back below 70°C, the safety temperature
limiter can be manually released for a restart of the
boiler.
Safety valve against overpressure
Asafety valve with 3 bar opening pressure has already
been installed on the boiler at the factory. If solar or
other heat sources provide energy to the buffer
storage tank via a heat exchanger, a safety valve
(3 bar maximum) is also required on the buffer storage
tank.
Fig. 3-3: Safety valve
Normally an expansion tank that is too small or
defective, or blocked heating lines are the cause of the
safety valve activation.
DANGER!
Safety valve outlet
The safety valve outlet must be directed to the ground
in a pipe so nobody is endangered by hot water or
steam.
The safety valve outlet must be directed to the
sewer via a clearly visible, open route (siphon
funnel), so that malfunctions, especially a failure of
the safety valve to close, can be detected. If no
sewer connection is available, the outlet must be
directed to the ground in a pipe.

Types of errors and their meaning
• Notification
A notification does not interrupt operation, and
therefore no acknowledgement is required. Notifi-
cations inform the user, for example, that pump
anti-blocking protection has been activated.
• Warning
A warning is displayed on failure of a function
which is not absolutely essential for continued
operation. It can be acknowledged before the
cause of failure is remedied. However, it will
continue to be displayed until the cause has
actually been dealt with.
• Malfunction or alarm
An error or alarm stops operation. Some of these
can be acknowledged before the cause of the
problem is remedied. However, they will continue
to be displayed until the cause has actually been
dealt with. Other errors and alarms can only be ac-
knowledged after the cause has successfully been
remedied. Once an error or alarm has been
resolved and acknowledged, you must restart the
boiler or the affected function block.

5.1.6.5 Switch between function blocks
The principle of "producers" and "consumers"
In the user interface, the "producer" of the function
block and (if present) also the "consumer(s)" are
displayed. Producers are those components of the
heating system that produce heat, for example the
boiler or the buffer. Consumers are those components
which absorb the heat, for example the heating circuit
or the hot water tank.
The principle of "producers" and "consumers" are
explained using the example of the buffer below. The
buffer is charged by the boiler. The boiler is a
"producer" for the buffer, and the buffer is a
"consumer" of the boiler.
The heating circuit and the hot water tank are
connected to the buffer. Thus, the buffer is a producer
for the two consumers, namely the heating circuit and
the hot water tank.
