The device can be updated. Firmware can be easily updated with the Jung ETS Ser-
vice App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against
manipulation in building automation and can be configured in the ETS project. De-
tailed technical knowledge is required. A device certificate, which is attached to the
device, is required for safe commissioning. During mounting, the device certificate
must be removed from the device and stored securely.
Planning, installation and commissioning of the device are carried out with the aid of
the ETS, version 5.7.7 and higher or 6.0.6.

Energy saving mode
The device switches to the energy saving mode after a preset time or by an external
telegram. In energy saving mode all LED functions are switched off. The device
leaves the energy saving mode – depending on programming – on operation or by an
external telegram.
Operations from the energy saving mode are executed immediately.
6 Operation
The operation of functions or electrical consumers can be set individual for each
device. Two operating modes are used:
– Single-area operation (button function):
Switching on or off, e.g. of lighting, takes place alternately when the button is
pressed repeatedly.
– Dual-area operation (rocker function):
Two buttons next to each other form a function pair. Pressing the left button,
for example, switches or dims lighting on or brighter, pressing the right one
switches it off or makes it darker.
Operating a function or load
￭ Switch: Short press on button.
￭ Dim: Long press on button.
￭ Move Venetian blind: Long press on button.
￭ Stop or adjust Venetian blind: Short press on button.
￭ Call up light scene: Short press on button.
￭ Save light scene: Long press on button.
￭ Set value, e.g. brightness or temperature setpoint: Short press on button.
￭ Adjusting value: Press button for a long time.
Depending on programming, a button triggers several functions after a longer
press or triggers another function if opposite buttons are pressed simultan-
eously.
7 Information for electrically skilled persons
DANGER!

DANGER!
Danger of electrical shock!
When mounting with 230 V socket outlets under a common cover there is a danger of
electrical shocks in the event of a fault!
Use only the enclosed plastic screws for fastening to the supporting frame!
￭ Mount supporting frame (3) in the right orientation on an appliance box. Note
marking TOP. Use only the enclosed box screws (10).
￭ Push frame (4) onto supporting frame.
￭ Connect the push-button sensor module (5) to the KNX with the KNX device
connection terminal (9) and push onto the supporting frame.
￭ Fix push-button sensor module to supporting frame using the enclosed plastic
screws (6). Tighten the plastic screws only lightly.
￭ Before mounting the buttons (7), load the physical address into the device.

7.1 Commissioning
Preconditions in secure operation
– Secure commissioning is activated in the ETS.
– Device certificate entered/scanned or added to the ETS project. A high resolu-
tion camera should be used to scan the QR code.
– Document all passwords and keep them safe.
Programming the physical address and application program
Project design and commissioning with ETS version 5.7.7 and higher or 6.0.6.
The device is connected and ready for operation.
If the device contains no – or an incorrect – application program, the labelling field
and the operation LED flash slowly.
Image3: Activating programming mode
￭ Activate programming mode: Press and hold push-button at the upper left
(11). Then press push-button at the lower right (12).
The operation LED flashes quickly.
￭ Programming the physical address.
The operation LED returns to its previous state – off, on, or flashing slowly.
￭ Programming the application program.
Installing the buttons
The buttons are available as a complete set of buttons (see accessories).
￭ Place the buttons on the device in the correct orientation and snap in with a
short push.
7.1.1 Safe-state mode
The safe-state mode stops the execution of the loaded application program.

j0082408003

If the device does not work properly - for instance as a result of errors in the project
design or during commissioning - the execution of the loaded application program
can be halted by activating the safe-state mode. The device remains passive in safe-
state mode, since the application program is not being executed (state of execution:
terminated).
Only the system software of the device is still functional. ETS diagnosis functions and
programming of the device are possible.
Activating safe-state mode
￭ Switch off the bus voltage.
￭ Press and hold down the top left and bottom right button.
￭ Switch on the bus voltage.
The safe-state mode is activated. The operation LED flashes slowly (approx. 1
Hz).
Do not release the buttons until the operation LED flashes.
Deactivating safe-state mode
￭ Switch off the voltage or carry out ETS programming.
7.1.2 Master reset
The master reset restores the basic device settings (physical address 15.15.255,
firmware remains in place). The device must then be recommissioned with the ETS.
In secure operation: A master reset deactivates device security. The device can then
be recommissioned with the device certificate.
If the device - for instance as a result of errors in the project design or during com-
missioning - does not work properly, the loaded application program can be deleted
from the device by performing a master reset. The master reset resets the device to
delivery state. Afterwards, the device can be put into operation again by program-
ming the physical address and application program.
Performing a master reset
Precondition: The safe-state mode is activated.
￭ Press and hold the button at the top left and the button at the bottom right for
more than five seconds until the operation LED flashes quickly (approx. 4 Hz).
￭ Release the buttons.
The device performs a master reset.
The device restarts. The operation LED flashes slowly.

Resetting the device to its default settings
Devices can be reset to factory settings with the ETS Service App. This function uses
the firmware contained in the device that was active at the time of delivery (delivered
state). Restoring the factory settings causes the devices to lose their physical ad-
dress and configuration.
