JUNG HOME blinds actuator 1-gang mini with 2 binary inputs
1 Safety instructions
To avoid potential damage, read and follow the following instructions:
Installation only by persons with relevant knowledge and experience in the
following areas:
– Five safety regulations and standards for the installation of electrical systems
– Selection of suitable tools, measuring devices, installation materials and, if ne-
cessary, personal protective equipment
– Installation of the installation material
– Connection of devices to the building installation under consideration of local
connection conditions
Improper installation will endanger your own life and the lives of persons who use the
electrical system, and there will be a risk of serious damage to property, e.g. due to
fire. You are at risk of personal liability for personal injury and damage to property.
Consult an electrically skilled person.
The device must not be used for applications from the field of safety engineering,
such as emergency stop, emergency call or smoke extraction.
Risk of injury. Use the device only to control venetian blind and shutter motors or
awnings. Do not use it to switch other loads.
Use only venetian blind motors with mechanical or electronic limit switches. Check
the limit switches for correct mastering. Observe the information on the motors from
the manufacturing company. Device can be damaged.
For parallel connection of several motors to an output it is essential to observe the
corresponding instructions of the manufacturing company, and to use a cut-off relay if
necessary. The motors may be destroyed.
Read the instructions in full, observe them and keep them for future reference.

Behaviour after a mains voltage failure
All settings and time programs are retained. Any missed switching times are not ap-
plied later. The load output is not activated, provided the parameter "Behaviour after
the mains voltage returns" is set to its default setting.
If the device was not previously added to a Bluetooth Mesh network (project) by
means of the JUNG HOME app, it will switch to pairing mode for two minutes when
the mains voltage returns and the status LED will flash slowly at a regular interval in
blue.
Power failure shorter than power reserve (min. 4 hours)
– Time and date are up to date
– The following time programs are performed normally again
Power failure longer than power reserve (min. 4 hours)
– The LED flashes blue three times repeatedly until the time is automatically up-
dated when connected with the app

– The time programs are not executed as long as the time has not been set
5 Operation
All settings and operations of the device can be configured individually using the
JUNG HOME app.
The binary inputs and the venetian blind actuator of the device can be used inde-
pendently of one another. For example, a Multi push-button connected to the binary
inputs can operate a switch insert (combined with a JUNG HOME push-button),
whereas the venetian blind actuator is controlled only with the app and time pro-
grams.
Operation via binary inputs
If a push-button (e.g. 531 U or 505 TU) is connected to a binary input, its actuation
will trigger different functions, depending on the duration of actuation (see table).
Configuration in the JUNG HOME app: The push-button is connected either to input
E1 or E2 to control a device, area or scene. The second input can then be used with
another push-button for a different device or area or another scene. The link must be
deactivated in the configuration view of the app for this purpose.

2 brief push-button action < 1 s < long push-button action
If a Multi push-button (e.g. 531-41 U) is connected to both binary inputs, operation of
the upper or lower button area will trigger different functions, depending on the dura-
tion of operation (see table).
Configuration in the JUNG HOME app: The two buttons of the Multi push-button are
connected to input E1 and E2 to control a device, area or scene together. The link
must be activated in the configuration view of the app for this purpose. If two different
scenes 1 and 2 are called up via E1 and E2 with a Multi push-button, the link must be
deactivated.

If a venetian blind push-button (505 TU without locking recommended, for example,
since mutual locking of the buttons is not necessary with binary inputs) is connected
to both binary inputs, operating the left or right button will trigger different functions
(see table).
Configuration in the JUNG HOME app: The two buttons of the venetian blind push-
button are connected to input E1 and E2 to control a device or area together. The link
must be activated in the configuration view of the app for this purpose.

Wireless operation
Wireless operation is done with linked JUNG HOME devices or via the JUNG HOME
App, which is also used to link the JUNG HOME devices (see 'Commissioning via
App').

6 Mounting and electrical connection
The communication of the JUNG HOME devices and linked mobile end devices is
done in wireless mode within the range of the Bluetooth Mesh network.
Wireless signals can be affected in their range through:
– Number, thickness, position of ceilings, walls and other objects
– Material type of these objects
– High-frequency interfering signals
Observe the following fitting instructions to maximise the range:
– Plan the positions and number of JUNG HOME devices to keep the number of
ceilings and walls between two devices as low as possible
– If JUNG HOME devices are installed on both sides of a solid wall, they should
be positioned as close as possible to each other on the opposite sides of the
wall. This keeps the attenuation of the wireless signal through the wall as low
as possible.
– When planning, observe that the number of building materials and objects that
attenuate the wireless signal strongly (e.g. concrete, glass, metal, insulated
walls, water tanks, pipelines, mirrors, book cabinets, storage rooms and refri-
gerators) on the connection line between JUNG HOME devices is as low as
possible
– Keep a distance of at least 1 m from devices that emit high-frequency signals
(e.g. microwave, motors) or run with wireless signals at 2.4 GHz (e.g. WLAN
router, baby monitor, IP cameras, wireless loudspeakers etc.)
DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Always disconnect before carrying out work on the device or load. For this, switch off
all corresponding circuit breakers, secure against being switched on again and check
that there is no voltage. Cover up adjacent live parts.

￭ Connect the venetian blind actuator (4) according to connection examples
(see figure 2) to (see figure 5). Observe the clampable conductor cross-sec-
tions (see figure 8).
Lit push-buttons must have a separate N connection terminal.
￭ Insert the actuator in the appliance box in such a way that the Prog button and
status LED are visible.
