KNX USB interface stick
The requirements for communication between the
ETAtouch control system and the KNX installation bus
are:
• Software version X.49.0 or higher is installed on
the ETAtouch control panel
• ETAtouch control panel of the generation [BE-P2]
or [BE-P3]
A "KNX USB interface stick," which is connected to the
ETAtouch control system [BE-P], serves as the
interface for the KNX installation bus for the ETAtouch
control panel.
Fig. 2-1: KNX USB interface stick
Connect the KNX bus line to the USB interface stick.
The KNX polarity is marked on the housing with +/-;
see the graphic below.
Fig. 2-2: Correct KNX polarity
Further details on the KNX USB interface stick
can be found in the manufacturer's operating in-
structions in Chapter 4 "Appendix".
Plug the KNX USB interface stick into a free USB port
on the ETAtouch control panel. Use the supplied USB
extension for this.
Fig. 2-3: USB connections on the control panel [BE-P3]
Fig. 2-4: USB extension for KNX bus
The configuration is performed via the "ETS"
programming software (version 5 or higher) on a
laptop or PC. The possible parameters and communi-
cation objects from the ETAtouch control system are
listed in Chapter 3 "Adjustable parameters".
Establish a KNX connection to the ETAtouch
control system
1. Make sure the KNX USB interface stick is
connected to the ETAtouch control panel.
2. On the ETAtouch control system, press the
(bottom left) symbol to open the system settings.
Press the [Authorisation] button. Enter the
password "135" and confirm this.

3. Switch to the [Internet & interfaces] menu and
select [KNX bus system]. An overview opens.
Fig. 2-5: Overview of the KNX interface
4. The [Programming button] button must be
pressed to allow the KNX USB interface stick to be
identified. An address can then be assigned to the
USB interface stick using the "ETS" programming
software.
If the error symbol appears among the
symbols for USB and KNX (in the upper left
area), check whether both the USB interface stick
and the KNX bus line are connected correctly.
5. The assignment of the function blocks, e.g., hot
water tank [WW] to the KNX groups is performed
via the selection list for the respective function
block. Select the [Not used] setting for those
function blocks that are not required for KNX com-
munication.
Fig. 2-6: Assignment
6. Once the assignment has been made, close the
window. Following this, the ETAtouch control
system must be restarted to save and activate the
KNX connection.
The ETAtouch control system must be
restarted for all changes to the configuration
with the "ETS" programming software and
subsequent installation on the KNX USB interface
stick.

Adjustable parameters
3 Adjustable parameters
Parameters from the ETAtouch control system for communication via the KNX bus
The following applies to all parameters: If a value greater than 0 is set at [Transmit cyclical?], the ETAtouch control
system sends the values at the set interval. The value "0" deactivates the regular transmission of the values. It can
also be set for all parameters if there is a change in value (e.g., temperature change of 1°C), regardless of whether
these are transmitted or not. In the general settings, the ETAtouch control system can transmit the time and in
adjustable intervals.
The factory settings of the "flags" for the individual communication objects are listed in the following tables. The flags
can be adjusted as needed. The abbreviations mean the following:
• C = Communication (always set)
• R = Read
• W = Write
• T = Transmit
The R flag must be set to facilitate reading. The last value written into the object via the bus is read out. If no
(or no reasonable) value is output for a communication object, the setting [Transmit on change in value?] may
be deactivated in the "ETS" programming software, or [Transmit cyclical?] may be set to 0.
The ETAtouch control system must be restarted for all changes to the configuration with the "ETS"
programming software and subsequent installation on the KNX USB interface stick.
