2.1 Getting to know the control
system
Get to know the control system
Take your time and read the following chapter
carefully. It describes the functions and settings of the
ETAtouch control for your heating system. If you are
familiar with these, it will be easier for you to make ad-
justements, even without consulting the manual.
Design of the control system
The individual components of the heating system, e.g.
buffer, hot water tank or heating circuit are shown in
the control system as "function blocks". These are
listed in the uppermost row on the screen. The
respective user interface is opened with a single tap of
the finger.

1 Currently selected function block
2 Other function blocks, e.g. hot water tank, heating
circuit, solar heating system
3 Scroll to other function blocks (displayed if not all
function blocks can be displayed simultaneously)
4 This button opens an overview of all installed
function blocks. This allows the user to switch
between function blocks faster.
5 Help button. Details can be found in chapter 2.1.3
"Integrated help".

In the user interface, you can set the most
important and common settings. For example,
adjustment of the charging times, heating
times, room temperatures and operating modes are
contained in this list. Details can be found in chapter
2.1.1 "User interface".
The parameters of a function block are
displayed in the text menu and can be adjusted,
if necessary. See chapter 2.1.2 "Text menu".

at the top of the screen in the corresponding function

screen.
Fig. 2-9: Error message
Types of errors and their meaning
• Message
A message does not interrupt operation, and
therefore no acknowledgement is required.
Messages inform the user, for example, that the
blocking protection of the pumps has been
activated.
• Warning
A warning is displayed when a function that is not
absolutely essential for continued operation has
failed. 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.
• Fault or alarm
A fault 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.
