Operating instructions
1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
The device may not be opened or operated outside the technical specifications.
Danger of electric shock. Device is not suitable for disconnection from supply voltage.
Danger of electric shock. Make sure during the installation that there is always sufficient insula-
tion between the mains voltage and the bus. A minimum distance of at least 4 mm must be
maintained between bus conductors and mains voltage cores.
Danger of electric shock on the KNX installation. Do not connect any external voltage to the in-
puts. The device might be damaged, and the SELV potential on the KNX bus line will no longer
be available.
For parallel connection of several motors to an output it is essential to observe the correspond-
ing instructions of the manufacturers, and to use a cut-off relay if necessary. The motors may be
destroyed.
Use only venetian blind motors with mechanical or electronic limit switches. Check the limit
switches for correct adjustment. Observe the specifications of the motor manufacturers. Device
can be damaged.
These instructions are an integral part of the product, and must remain with the end customer.

3 Function
System information
This device is a product of the KNX system and complies with the KNX directives. Detailed tech-
nical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on loadable soft-
ware and attainable functionality as well as the software itself can be obtained from the manu-
facturer´s product database.
The device can be updated. Firmware can be easily updated with the Jung ETS Service App
(additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against manipula-
tion in building automation and can be configured in the ETS project. Detailed specialist know-
ledge is required. A device certificate, which is attached to the device, is required for safe com-
missioning. During mounting, the certificate must be removed from the device and stored se-
curely.
Planning, installation and commissioning of the device are carried out with the aid of the ETS,
version 5.7.3 and above.

4.1 Fitting and electrical connection
DANGER!
When connecting the bus/extensions and mains voltage wires in a shared appliance
box, the KNX bus line may come into contact with the mains voltage.
This endangers the safety of the entire KNX installation. People at remote devices
may also receive an electric shock.
Do not place bus/extensions and mains voltage terminals in a shared connection
compartment. Use an appliance box with a fixed partition wall or separate appliance
boxes.
Connecting and fitting the device
In secure operation (preconditions):
– Secure commissioning is activated in the ETS.
– Device certificate entered/scanned or added to the ETS project. A high resolution camera
should be used to scan the QR code.
– Document all passwords and keep them safe.
Mounting in suitable appliance box (recommendation: electronic device box with partition). Ob-
serve cable routing and spacing (Figure 3)!

Figure4: Cable spacing
Minimum spacing between the mains voltage and bus/extension wires: 4 mm (Figure 4)
Figure5: Connection of load
Observe ambient temperature. Ensure adequate cooling.
￭ Connect the device to KNX with the correct polarity.
￭ Connect load as shown in the connection example (Figure 5).
￭ If required, connect potential-free contacts or dew/leakage sensors to inputs 1...3, or NTC
temperature sensors to input 3 (Figure 2).
￭ Install the device in the appliance box.
￭ In secure operation: The device certificate must be removed from the device and stored
securely.
The COM reference potential must not be connected together with COM connections of
other devices!

4.2 Commissioning
Commissioning the device
NOTICE!
Incorrect load control due to undefined relay state at delivery.
Risk of destruction of connected drive motors.
During commissioning, before switching on the load, ensure that all relay contacts
are open by applying the KNX bus voltage. Observe commissioning sequence!
￭ Switch on the KNX bus voltage.
￭ Wait about 10 s.
￭ Connect the load circuit.
Delivery state: The output is set as a blind output. Operation of the blind output possible
via input 1 (UP) and input 2 (DOWN). Input 3 has no function.
Function of Inputs in the as-delivered state
Input Push-button (NO contact) Function
1 Press briefly (< 0.4 s) Stop
1 Press briefly (< 0.9 s) Adjusting the slats UP
1 Press for a long time (> 0.9
s)
Raise
2 Press briefly (< 0.4 s) Stop

Load physical address and application program
￭ For switched loads, configure the outputs as a switching output.
￭ For Venetian blind operation, configure the outputs as a Venetian blind output.
￭ In Venetian blind operation: measure blind/shutter and slat travel times and enter them in
the parameter setting.
￭ Press the programming button.
The programming LED lights up.
￭ Load physical address and application program using the ETS.
Safe-state mode
The safe state mode stops the execution of the loaded application program.
Only the system software of the device is still functional. ETS diagnosis functions and pro-
gramming of the device are possible.
Activating the safe-state mode
￭ Switch off the bus voltage or disconnect the device from the KNX.
￭ Wait about 10 s.
￭ Press and hold down the programming button.
￭ Switch on the bus voltage or connect the device to KNX. Release the programming button
only after the programming LED starts flashing slowly.
The safe-state mode is activated.

Switch actuator, 2-gang / blinds actuator, 1-gang
With a new brief press of the programming button, the programming mode can be
switched on and off as usual also in the safe-state mode. If Programming mode is active,
the programming LED stops flashing.
Deactivating safe-state mode
￭ Switch off bus voltage (wait approx. 10 s) or carry out ETS programming.
Master reset
The master reset restores the basic device setting (physical address 15.15.255, firmware re-
mains in place). The device must then be recommissioned with the ETS.
During secure operation: A master reset deactivates device security. The device can then be re-
commissioned with the device certificate.
Performing a master reset
Precondition: The safe-state mode is activated.
￭ Press and hold down the programming button for > 5 s.
The programming LED flashes quickly.
The device performs a master reset, restarts and is ready for operation again after ap-
prox. 5 s.
Restoring the device to factory settings
Devices can be reset to factory settings with the Jung ETS Service App. This function uses the
firmware contained in the device that was active at the time of delivery (delivery state). Restor-
ing the factory settings causes the devices to lose their physical address and configuration.
