from the owner.
Subject to technical alterations
We reserve the right to make technical modifications
without notice. Printing and typesetting errors or
changes of any kind made in the interim are not cause
for claims. Individual configurations depicted or
described here are only optionally available. In the
event of contradictions between individual documents
regarding delivery scope, the information in our current
price list applies.

Types of safety instruction
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
a risk of major physical injury.
Illustrations
The illustrations in this documentation portray the
wood chip boiler merely as an example which stands
for all ETA boilers.
Electrical connection must only be made by
qualified specialist personnel
The electrical installation must only be performed
by specialist personnel with the corresponding
qualifications.
1.2 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.
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.
Repairs
Repairs are only permitted using spare parts provided
by us. The only exceptions are commonly available
standard parts such as electrical fuses or fastening
materials, provided such parts have the necessary
features and do not compromise the safety of the
system.
Proper installation
The installing contractor is liable for proper installation
according to the correspondinginstallation 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.

1.3 Safety
DANGER!
Electric shock
There are live parts on the circuit boards. If
touched, they can cause injury and
property damage.
Before beginning any work, isolate the system
completely from all power sources, ensure that it
cannot be switched back on, and verify that it is
safely isolated from supply.
WARNING!
Configuration errors caused by multiple use of
node numbers with circuit boards and ETAtouch
control panels of the same type
It is impossible to identify circuit boards and ETAtouch
control panels when node numbers are assigned more
than once.
Set the node numbers correctly and conclude by
checking them once again.
CAUTION!
Flexible stranded conductors
If flexible stranded conductors are not used for the
wiring, the contacts in the plug connections will be
subjected to excessive mechanical strain. In this case,
the warranty for the electronics would become null and
void.
Only flexible stranded conductors may be used for
the wiring.

Functional description
2 Functional description
T2-BT control extension
The T2-BT control extension adds an ETAtouch
control panel and additional interfaces to the existing
ETAtouch controller.
Possible extensions include:
• 2 extra heating circuits with mixing valve
• 1 extra hot water tank
• 1 extra fresh water module
• Solar heating system with 1 or 2 tanks
• Solar heating system with stratified charging
module
A circulation pump, or a light or horn to indicate mal-
functions, can be connected with the integrated sup-
plementary relay (potential-free changeover contact).
A USB flash drive is supplied with each control
extension for storing the configuration. We
recommend keeping it in the wall housing.
T4-0 control extension
The T4-0 control extension with the MK-E circuit board
can be optionally added to the control extension's wall
housing.
Extension:
• 2 extra heating circuits with mixing valve
