3 Safety and operating instructions
KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.
1. Safety and operating instructions
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.
CAUTION!
Live voltage!
• Inspect the device for damage before installation. Only put undamaged
devices into operation.
• Comply with the locally applicable directives, regulations and provisions for
electrical installation.
• Immediately take the device or system out of service and secure it against
unintentional switch-on if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating
instructions. Improper use, modifications to the device or failure to observe the
operating instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition and
after conclusion of all installation and operational start-up tasks, and only in the
surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
For information on installation, maintenance, disposal, scope of deliv-
ery and technical data, please refer to the installation instructions.
2. Description
The KNX eTR 208 Light/Sunblind push button has touch-sensitive buttons with
which functions can be called up in the KNX building bus system. The glass surface is
printed with areas for setting the temperature, light and solar protection. LEDs are in-
tegrated in these areas and their behaviour can be adjusted.
A temperature sensor is integrated into KNX eTR 208 Light/Sunblind. An external
temperature reading can be received via the bus and processed with its own data to
create a total temperature (mixed value).
The KNX eTR 208 Light/Sunblind has a PI controller for heating and cooling. The
setpoint temperature can be changed using the "+" and "-" touch buttons.
Communication objects can be linked via AND and OR logic gates.
Functions:
•Operating zone for temperature control with 2 areas (warmer, cooler)
•Operating zone for light with 2 areas (switching and dimming)
4 Description
KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.
•Operating zone for blinds, awnings, shutters or windows with 2 areas (up/
down with short/long distinction)
•LEDs can be set. All LEDs Off, all LEDs as ambient lighting, all LEDs
individually controllable
•Area function when touching two or more push buttons. Can be configured
as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
•Temperature measurements. Mixed value from own measured value and
external values (proportion can be set by percentage), output of minimum and
maximum values
•PI-controller for heating (one or two-level) and cooling (one or two-level)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature
•2 AND and 2 OR logic gates each with 4 inputs. 8 logic inputs (in the form
of communications objects) can be used as inputs for the logic gates. The
output from each gate can be configured optionally as 1-bit or 2 x 8-bit
2.0.1. Area function
If the area function in ETS has been activated, another function is available alongside
the regular key functions. This is triggered by touching multiple keys, e.g. if you touch
the sensor with the palm of your hand.
Using the area function
If a key is pressed and another (different) key is touched within 0.2 seconds, the action
set in the ETS is performed for the area operation (See Fig. 1 a) and b)). The keys are
then blocked for 0.5 seconds.
Using the normal key function
If a key is pressed and no other key is touched within 0.2 seconds, the normal key
function is enabled/provided for 5 seconds (See Fig. 1 c) and d)). This is extended for 5
seconds with each push of the button.
5 Commissioning
KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.
If the area function in the ETS is disabled, the keys can be used normally at any time.
3. Commissioning
Configuration is made using the KNX software as of ETS 5. The product file can be
downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de.
After the bus voltage has been applied, the device will enter an initialisation phase last-
ing approx. 5 seconds. During this phase no information can be received or sent via the
bus.
4. Addressing the device
The device is delivered ex works with the bus address 15.15.255. You program a differ-
ent address in the ETS by overwriting the address 15.15.255 or teach the device using
the programming button.
The programming button is located at the bottom outer side of the front panel of the
device and is recessed. Use a thin object to reach the button, e. g. a 1.5 mm² wire.
When the button is pressed, the temperature display on the front flashes.

6 Display and operation at the device
KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.
5. Display and operation at the device
5.1. Adjust room temperature
Depending on the setting of the "Display mode" parameter in the device application,
the KNX eTR 208 Light/Sunblind push button displays the current room
temperature value (or mixed value), the target value or the shift in relation to the basic
setpoint. The display can be dimmed and switched off via the bus so that no value is
displayed.
Option A: Display of actual temperature (room temperature)
The current room temperature is displayed. It is not possible to change the room
temperature manually using the +/- buttons.
Option B: Display of target temperature or basic setpoint shift
Depending on the setting, the current target value or the shift relative to the base
setpoint is displayed. The temperature can be changed by touching the +/- buttons.
Target value display (absolute value):

Display of the basic setpoint shift (change compared to the basic setpoint of the
control):
Option C: Display of actual temperature and target temperature/basic
setpoint shift
During normal operation, the current room temperature is displayed. By touching the
buttons, the display jumps to the target temperature or to the basic setpoint shift,
depending on the presetting. Changes with + or - are visible. The display returns to the
room temperature if no button is touched for 7 seconds.
Touch the + or - button briefly: The current target temperature (or the basic setpoint
shift) is displayed.
Tap +: Increase room temperature
(target temperature/basic setpoint shift is increased).
Tap -: Lower room temperature
(target temperature/basic setpoint shift is lowered).

General:
The step size for the change and the possible setting range are defined in the device
application (ETS). There you can also define whether the manually changed values are
retained after a mode change (e.g. Eco mode overnight) or reset to the stored values.
The button functions can be disabled in the ETS or locked due to operating mode with
priority 1.
