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

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.

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.

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.

￭ Switch on mains voltage.
The venetian blind / shutter / awning can be moved as a test by briefly press-
ing the Prog button (1).
￭ Mount the cover.
7 Commissioning via app
Prerequisite: the JUNG HOME device has not yet been made a participant in a
Bluetooth Mesh network; otherwise reset the device to factory defaults.
If a Bluetooth Mesh network (project) does not yet exist, start by creating a new pro-
ject for the first JUNG HOME device in the JUNG HOME app.
If a Bluetooth Mesh network already exists, the project file for this network must be
opened in order to pair the new device.
After switching on the mains voltage, the device is automatically in pairing
mode for two minutes.
Image6: Commissioning
￭ Activate pairing mode manually:
Press the Prog. button (1) for more than 4 seconds.
JUNG HOME blinds actuator 1-gang mini with 2 binary inputs
11 / 21
82407503 09.05.2023
J0082407503

The status LED flashes blue slowly. Pairing mode is active for two minutes.
￭ Start the JUNG HOME app.
The app shows all devices in pairing mode.
￭ Select a device in the app.
To identify the selected device, its status LED flashes more quickly in blue.
￭ Add the device to the project.
The status LED lights up in blue for five seconds to confirm that pairing was
successful.
If the status LED flashes red very fast, pairing has failed and needs to be re-
tried.
The JUNG HOME app can then be used to link devices wirelessly and configure the
parameters and operation (see list of functions and parameters).
Once the commissioning has been completed, hand over the project file to the
owner.
Besides basic commissioning, the JUNG HOME app enables device updates and
convenient operation of further individual configuration options:
– Link: A button, binary input or motion sensor can be controlled by linking it to a
load (e.g. dimmer, socket, relay, shutter, etc.). Several loads can be con-
trolled together by linking them to an area or scene.
– Area: Different loads (e.g. dimmer, socket, relay, shutter, etc.) can be grouped
in an area to allow them to be controlled together.
– Scene: Different loads (e.g. dimmer, socket, relay, shutter, etc.) can be
grouped in a scene so that, by calling up a scene, each load assumes the load
status stored in the scene.
– Automatic function: An automatic function can be used to control the locally
connected load (no wireless link) by means of time programs. Depending on
the device type, there are further automatic functions in JUNG HOME, such as
hotel function, night light function, holiday program or switching thresholds.

8 Resetting the device to the factory setting
If the button Prog. (1) is disabled with the "operating lock" parameter, the default set-
ting can be reset to only within two minutes after switching on the mains voltage.
Image7: Factory reset
￭ Press the button Prog. (1) for more than 20 seconds until the status LED (2)
quickly flashes in red.
￭ Release the Prog. (1) button and press briefly once again within 10 seconds.
The status LED flashes in red more slowly for approx. five seconds. The
device has been reset to the default setting.
After resetting the device to the default setting, it must be removed from the JUNG
HOME app provided it has not already been deleted from the app.

10 List of functions and parameters
Adjustable parameters via app
The JUNG HOME app can be used to configure all functions of the JUNG HOME
device and its behaviour in the Bluetooth Mesh project for the respective individual
purposes.
Two devices are created in the app when commissioning with the app:
– A device that maps the two binary inputs and includes its functions and para-
meters.
– A device that maps the venetian blind actuator and its load control with all the
corresponding functions and parameters.
All devices created in the JUNG HOME app can be used independently and set sep-
arately.

Explanations
Operating
concept
E1/E2 combined, E1/E2

Default setting: E1/E2
combined
E1/E2 combined: corresponds to the
"rocker" operating concept for the JUNG
HOME push-button. Inputs E1 and E2 op-
erate together a device, area or disabling
function. Switching edges at E1 or E2
usually lead to directly opposite reactions
(e.g. light ON/OFF, brighter/darker, up/
down).
E1/E2 separately: corresponds to the
"button" operating concept for the JUNG
HOME push-button. Inputs E1 and E2
can be used separately and each operate
a device or area or activate a scene.
When controlling loads or areas, a re-
newed switching edge at the same input
leads to opposite reactions (e.g. light
ON/OFF, brighter/darker, up/stop/down).

The input behaviour can be configured for
a rising edge (voltage at input is switched
on) and for a falling edge (voltage at input
is switched off) independently of one an-
other. The effect of the setting depends
on the function of the linked load. The "no
reaction" option has the effect that the
linked device does not change its status if
the selected edge is detected at the bin-
ary input.
Operating lock** No lock, factory reset
lock, operating lock
Default setting: no lock
Factory reset lock: prevents resetting on
the device and hence the removal from a
project and pairing again by unauthorised
persons. After the mains voltage returns,
the factory reset lock is deactivated for
two minutes.
Operating lock: prevents normal opera-
tion on the device and hence the load
from being controlled. This lock can be
used, for example, to restrict manual ac-
cess temporarily.
Operation via the app remains possible.
The operating lock cannot be deactivated
on the device.

Astro timer** Off, sunrise or sunset
Default setting: Off
The astro timer shows the sunrise and
sunset times in the course of a calendar
year. Depending on the location, venetian
blinds, shutters or awnings can be
changed with the position of the sun, for
example to close a venetian blind at sun-
set and open it again at dawn.

If you want the time program to be ex-
ecuted in the early morning before the
start of twilight or only at full brightness,
this can be implemented with the "sun-
rise" shift.
If you want the time program to be ex-
ecuted in the evening at the start of twi-
light or only at full darkness, this can be
implemented with the "sunset" shift. Dis-
places the actuation time for the venetian
blind, shutter or awning by the set value.
Astro timer**

Off, earliest time, latest
time default setting: off
To narrow the time range of an astro
timer down to an earliest and/or latest ex-
ecution time.
For example, a shutter can be closed at
the latest at 9:00p.m. even if the sun
does not set until 10:00p.m.
Set location** Geographic location The astro timer in the JUNG HOME
devices needs the geographic location of
the project to calculate the sunrise or sun-
set time. The astro timer is calculated
once a week for the localised place.

Shutter: A shutter or an awning is con-
trolled for which the Fabric-stretching
function is required.
Venetian blind: A venetian blind is con-
trolled.
Awning: An awning is controlled for which
the Fabric-stretching function is required.
Running time 1s ... 10min
Default setting: 2 min
Absolute time it takes for the venetian
blind, shutter or awning to move from the
retracted to extended end position.
This entry is required to display the cur-
rent position of the venetian blind, shutter
or awning and perform precise positioning
movements. This entry is therefore made
in the app directly after the JUNG HOME
push-button has been added to a project -
but can be subsequently corrected.

Absolute time for changing-over venetian
blind slats. Here, the fabric-stretching
time can be set for the operation of awn-
ings.
Inverting out-
puts
Off, On
Default setting: Off
Inverts the activation of the relay outputs.
During inverted operation, the "Up" and
"Down" relay outputs are controlled ex-
actly the other way around. This is re-
quired, for example, for skylight control-
lers or may help if a venetian blind / shut-
ter / awning is running in the wrong direc-
tion. This parameter inverts only the be-
haviour of the load outputs, but neither
the operation of the JUNG HOME push-
button nor the display of the running dir-
ection in the app.
