KNX eTR 202 Sunblind
Button for Temperature Control
and Solar Protection
Technical specifications and installation instructions
1. Description
The KNX eTR 201/202 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 and solar protection. White LEDs
are integrated in these areas and their behaviour can be adjusted.
A temperature sensor is integrated into KNX eTR 201/202 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 201/202 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)
•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
Additional functions KNX eTR 201 Sunblind:
•1 operating zone for blinds, awnings, shutters or windows with 2 areas
(up/down with short/long distinction)
Additional functions KNX eTR 202 Sunblind:
•2 operating zones for blinds, awnings, shutters or windows with 2 areas
(up/down with short/long distinction)
Configuration is made using the KNX software ETS 5. The product file can be
downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the “Service” menu.
1.0.1. Area function
If the area function in ETS has been activated, another function is available along-
side 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 ac-
tion 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.
If the area function in the ETS is disabled, the keys can be used normally at any ti-
me.
1.0.2. Scope of delivery
• Room temperature controller with mounting
• 4 screw anchors 4 × 20 mm, 4 flat head screws 3 × 25 mm
1.1. Technical specifications
The product conforms with the provisions of EU guidelines.
1.1.1. Accuracy of the measurement
Measurement variations from permanent sources of interference (see chapter Ins-
tallation position) can be corrected in the ETS in order to ensure the specified ac-
curacy of the sensor (offset).
When measuring temperature, the self-heating of the device is compensated.

KNX eTR 201/202 Sunblind push button 2
KNX eTR 201/202 Sunblind push button • Version: 26.10.2020 • Technical changes and errors excepted. • Elsner Elektronik GmbH • Sohlengrund 16 • 75395 Ostelsheim • Germany • www.elsner-elektronik.de • Technical Service: +49 (0) 7033 / 30945-250
Screw the mounting onto the wall or socket. The connecting wires (bus line +/-) are
led through the opening in the mounting.
Installation directly on the wall
The wires are pushed into the connection openings.
Installation on a socket
To avoid falsifying the temperature value, use a wind-proof socket and also seal
the inlet pipes against draughts.
Finish mounting
Snap the front panel into place on the mounting (see Fig. 4): Place it slightly above
the centre position, hook it in and slide it downwards.
2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electro-
nics. You must not exceed a relative humidity of 95%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase
lasting a few seconds. During this phase no information can be received or sent via
the bus.
3. Addressing the device
The device is delivered ex works with the bus address 15.15.255. You program a
different address in the ETS by overwriting the address 15.15.255 or teach the de-
vice 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.
4. Display and operation at the device
4.1. Adjust room temperature (using the example KNX
eTR 201 Sunblind)
Depending on the setting of the "Display mode" parameter in the device applicati-
on, the KNX eTR 201/202 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 re-
turns to the room temperature if no button is touched for 7 seconds.
Touch the + or - button briefly: The current target temperature (or the basic set-
point 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 de-
vice 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.
5. Maintenance and care
Fingerprints on the glass panel are best removed with a cloth moistened with wa-
ter or a microfiber cloth. Do not use an abrasive cleaning agent or aggressive cle-
ansing agents.
6. Disposal
After use, the device must be disposed of or recycled in accordance with the legal
regulations. Do not dispose of it with the household waste!
Remove the red-black KNX bus terminal, it
is not required.
Connect the bus +/- connecting wires to the
spring-loaded terminals on the front panel.
