2 Description of the configuration wizard
Configuration with the wizard
Configuration with the wizard takes place in several
steps. These are described below:
1) Add the function blocks required for the installed
heating system components. Choose your settings
and options individually in each function block.
2) When you have added all the necessary function
blocks, set the individual connections between
"producers" and "consumers".
"Producers" are components that provide heat or
fuel. "Consumers" consume this heat or fuel.
3) Next, the terminal assignments of each function
block is displayed on the corresponding circuit
board. In this step, the heating system
components are electrically connected. You may
also adjust the terminal assignments during this
step.
4) Finally, the configuration is installed, and the
software rebooted.
After this, you can make customer-specific
adjustments to the heating system, such as: buffer
charging times, room temperatures for the heating
circuit, hot water temperatures, etc.
When you have completed these customer adap-
tations, save this configuration. It is saved in the
ETAtouch control system. You can additionally save it
on a USB stick.
The description below explains the general way
in which the configuration wizard works. Your
heating system's individual configuration depends on
the installed components, and can vary.
Starting the configuration assistant
Switch to the system settings and increase the
authorization to [Service]. Then open the system con-
figuration menu with the [Systems configuration]
button.

4 Backing up and restoring a configuration
Backup configuration
After you have made adjustments to satisfy customer
requirements, you should save the configuration. This
backup saves the configuration, parameter settings,
input and output terminal allocations, etc. – in other
words, all relevant data and settings in the ETAtouch
control system. This makes it possible to quickly
restore the original settings.
Backup configuration
1. In the system configuration , increase the au-
thorisation to [Service] and open the system con-
figuration menu with the [Systems configuration]
button.
Fig. 4-1: System configuration menu
2. Press the [Configuration save] button to start
the backup. Once this is finished, a message
appears on the screen prompting an additional
backup to a USB stick. If you wish to do this, insert
the USB stick into the port on the boiler and
perform the backup.
Restoring the configuration
You can restore the heating system configuration at
any time. The configuration is restored either from a
configuration saved in the ETAtouch control system or
via a USB stick. The counter readings are not
overwritten by this.
Control systems in a wall mounted box are
supplied with a USB stick for backing up the con-
figuration. Leave this in the wall mounted box after you
have restored the configuration.
Restoring the configuration
1. In the system configuration , increase the au-
thorisation to [Service] and open the system con-
figuration menu with the [Systems configuration]
button. To restore a configuration, press the [Con-
figuration restore] button. Another menu
appears:
Fig. 4-2: Restore menu
2. In the upper part of the screen, select the source of
the configuration you wish to restore. Then select
the required backup in the lower part of the screen
with the button.
If the configuration has been loaded from a USB
stick, you should additionally back it up in the
ETAtouch control system. To do this, perform the
backup again.

Resuming commissioning Sample
5.1 Resuming commissioning
Continue heating system commissioning
Continue to commission the heating system and
perform a function test of components such as pumps,
mixing valves, temperature sensors, etc.
Next, make customer-specific adjustments to the
control system such as hot water temperatures, buffer
charging time slots, heating time slots and room tem-
peratures...
The required parameters are listed in Chapter 6 "Con-
figuration parameter".
Making a backup after commissioning
Back up the configuration straight away after you have
adapted the heating system to suit the customer's re-
quirements. See Chapter 4 "Backing up and restoring
a configuration".

6 Configuration parameter
6.1 [Boiler] function block - PU7-15
and PC20-32
Parameters to be set
Set or check the following parameters.
Explanation of [Lock aux. boiler]
Only set this parameter if the heating system is
equipped with an oil or gas auxiliary boiler. This
parameter determines whether the ETA boiler may be
in operation at the same time as the oil or gas auxiliary
boiler.
With the [No] setting, the ETA boiler and the oil or gas
boiler can be in operation simultaneously.
With the setting [Yes], either the ETA boiler or the
burner may be in operation, but not both. With
this setting, you also need to set the [Locking]
parameter to [Yes] in the burner function block.
Explanation of [Minimum pressure], [Max. water
pressure] and [Refill at water pressure]
The current heating system pressure is shown in
[Boiler pressure]. This submenu contains the
parameters [Minimum pressure], [Max. water
pressure] and [Refill at water pressure]. These set the
limits for the minimum and maximum heating system
pressure, and the warning limit for refilling the heating
system.
Do not set the minimum pressure to less than
0.8 bar, or the maximum pressure above [Max.
water pressure] 2.8 bar.
When you set the minimum pressure, pay
attention to the height of the system, and the pre-
set pressure of the expansion tank.
Set the [Refill at water pressure] warning limit
0.5 bar above the minimum pressure.
Explanation of [Start idle time]
This parameter is used to select the time after which
there is no more boiler de-ashing. This prevents
potential noise nuisance during the night. The duration
of this idle time is set by the [Duration idle time]
parameters.
Explanation of [Duration idle time]
The [Duration idle time] parameter is used to select the
duration of the idle time for the boiler's entire de-ashing
system.
The start time for the idle time is set with the [Start idle
time] parameter.
The idle time should be kept as short as possible.
If noise is not expected to be a nuisance, you
should reduce the value to 0 hours.
Explanation of [Empty ash box after]
This parameter adjusts the quantity of pellets used,
after which a reminder to empty the ash box is
displayed on the screen.
If the ash box is then only partially full, this quantity can
be increased. If you set the value to zero, the reminder
will no longer appear.

6.2 [BufferFlex] function block
6.2.1 Functional description
Description of the "PufferFlex"
Consumers connected to the buffer often require
different feed temperatures and produce different
return temperatures. A hot water tank or a radiator
heating circuit requires a flow of around 60°C, while an
underfloor heating requires one of 35°C. This results in
different temperature levels for the different
consumers. The "PufferFlex" function block now
makes it possible to better utilize these different
temperature levels (= consumer levels). For this, the
control system "separates" the buffer into different
levels.
The relevant buffer temperature sensors are assigned
for each level (see chapter 6.2.1.2 "Setting levels"). In
the control system, these are designated as [Sensor 1
(upper)], [Sensor 2], [Sensor 3], etc. The order always
corresponds from the top of the buffer to the bottom.
With this allocation, the control system can
analogously record the "starting" and "stopping" of the
load, as well as the heat demand requirements for
each level.
Example: Buffer storage tank with 3 temperature
sensors
A hot water tank (= high feed temperature) and a floor
heating circuit (= low feed temperature) are connected
to the buffer.The buffer can therefore be subdivided
into 2 temperature levels for the consumers.
The first level (for the hot water tank) is between
temperature sensors [Sensor 1 (upper)] and [Sensor
3].The second level (underfloor heating) is between
[Sensor 2] and [Sensor 3]. For the heat producer (e.g.
boiler), the entire temperature level of the buffer is
available, i.e. from [Sensor 1 (upper)] to [Sensor 3].
Fig. 6-1: Example: Temperature levels at the buffer
1 First consumer level (78°C - 36°C)
2 Second consumer level (59°C - 36°C)
3 Temperature level for the heat producer, e.g. boiler
(78°C - 36°C)
Of course, the same principle applies to multiple
temperature sensors on the buffer.A maximum of
3 consumer levels can be defined, whose ranges may
overlap.
Fig. 6-2: 3 consumer levels
1 First consumer level (78°C - 44°C)
2 Second consumer level (67°C - 35°C)
3 Third consumer level (35°C - 22°C)
The first consumer level is that for the consumers
with the highest required temperature.The
following consumer levels are for consumers with
lower temperatures.
For the control system to function optimally, the actual
installation height of the individual buffer temperature
sensors must be set in the control system.For more
information see 6.2.1.1 "Setting the installation height
of the temperature sensor".
The different levels can also be used to charge
the buffer, and thus also apply to heat producers
(e.g. boiler, solar heating system).For example, buffer
charging through the boiler can be restricted to the
upper level (e.g. for hot water), and solar heating
system charging to the lower level (e.g. for underfloor
heating). For more information, see chapter 6.2.1.2
"Setting levels".
In addition, the possibility of a warning being issued as
soon as an assigned temperature sensor exceeds or
falls below a limit value exists.See chapter 6.2.1.3
"Setting warnings".
If additional temperature sensors are retrofitted to
the buffer after commissioning, the installation
heights must also be adapted to these.Similarly, the
labelling of the temperature sensor, and thus the
respective assignment, shifts. A review and
adjustment of all temperature levels (for producers and
consumers) is then mandatory.
