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.

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.

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.
Fig. 6 Spring-loaded terminals
To pull it out, press the spring down, e.g.
with a screwdriver.
If there is a cavity behind the device, e.g.
when using a socket, you can use the red/
black KNX bus terminal for connection.
