1 Safety instructions
To avoid possible damage, read and follow the following instructions:
Installation only by persons with appropriate knowledge and experience in the
following areas:
– 5 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 endangers your own life and the lives of users of the electrical
system and there is a risk of serious damage to property, e.g. through fire. You are at
risk of personal liability for personal injury and damage to property.
Contact an electrical fitter!
The device must not be used in connection with consumers that could lead to danger
to life or limb or damage to property, e.g. heaters or electrical machines.
Danger of electric shock. Device is not suitable for disconnection from supply voltage
because mains potential even is applied on the load when the device is switched off.
Before carrying out work on the device or load, switch off all associated circuit break-
ers.
The device must not be used for applications from the area of safety engineering,
such as emergency stop, emergency call, smoke extraction.

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 switched off, provided the parameter "Switching state
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 are executed 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 to 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 switch actuator of the device can be used independently of
one another. For example, a Multi push-button connected to the binary inputs can op-
erate a venetian blind insert (combined with a JUNG HOME push-button), whereas
the switch actuator is controlled only by means of the app and time programs.
Operation via binary inputs
If a push-button (e.g. 531 U or 505 TU) is connected to a binary input, its operation
will trigger different functions, depending on the duration of operation (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
Communication between the JUNG HOME devices and linked mobile end devices is
performed wirelessly within the range of the Bluetooth Mesh network.
The range of wireless signals can be affected by:
– 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 number of JUNG HOME devices and their positions to keep the num-
ber 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, make sure that there are as few building materials and objects
as possible that strongly attenuate the wireless signal (e.g. concrete, glass,
metal, insulated walls, water tanks, pipes, mirrors, book cabinets, storage
rooms and refrigerators) on the connection line between JUNG HOME devices
– Keep a distance of at least 1 m from devices that emit high-frequency signals
(e.g. microwave, motors) or use 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 switch actuator (4) according to connection examples
(see figure 2) to (see figure 6). Observe the clampable conductor cross-sec-
tions (see figure 7).
Lit push-buttons must have a separate N connection terminal. If the lighting is
to be used as switching status feedback for a load linked wirelessly to the bin-
ary input, the switch actuator can be used to control the push-button lighting.
￭ Insert the actuator in the appliance box in such a way that the Prog button and
status LED are visible.
￭ Switch on mains voltage.
The load can be switched as a test by briefly pressing the button Prog (1).
￭ Mount the cover.
7 Commissioning via app
Prerequisite: The JUNG HOME device does not yet belong to a Bluetooth Mesh net-
work. Otherwise reset the device to the default setting.
If a Bluetooth Mesh network (project) does not yet exist, a new project must first be
created 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.

82405803 23.02.2023
J0082405803

After switching on the mains voltage, the device is automatically in pairing
mode for 2 minutes.
Image8: Commissioning
￭ Activate pairing mode manually:
Press the Prog. button (1) for more than 4 seconds.
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 blue for 5 seconds to acknowledge successful pair-
ing.
If the status LED flashes red very fast, pairing has failed and needs to be re-
tried.

82405803 23.02.2023
J0082405803

The JUNG HOME app can then be used to link devices wirelessly and config-
ure the parameters (see list of 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 controlled
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 de-
fault setting can be reset to only within two minutes after switching on the
mains voltage.

￭ 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 red more slowly for approx. 5 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 switch actuator and its load control with all the corres-
ponding 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
separately
Default setting: E1/E2
separately
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, load
statuses can be changed with the position
of the sun, for example to switch on the
outdoor lighting at sunset and switch it off
again at sunrise.
Astro timer**

Default setting: Off
Astro times represent the sunrise and
sunset times in the course of a calendar
year.
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 load actuation time by the set
value.
Astro timer**
limit range
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, the garden lighting can be
switched off at the latest at 9:00pm even
if the sun does not set until 10:00pm.
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.

Switch actuator settings Lj
Parameters Setting options, default
setting
Explanation
Switch-on delay 0 s (off) ... 240 min
Default setting: Off
Switches on the load after a switch-on
command, delayed by the value. Re-
peated switch-on commands during the
current delay do not start the delay again.
If the load has not yet been switched on
due to the delay, the load remains
switched off when a switch-off command
arrives.
Switch-off delay 0 s (off) ... 240 min
Default setting: Off
Switches off the load after a switch-off
command, delayed by the value. Re-
peated switch-off commands during the
current delay restart the delay time. If the
load has not yet been switched off due to
the delay when a switch-on command
comes, then the load will remain on.
Switch-off warn-
ing
Off, On
Default setting: Off
If the switch-off warning is switched on,
the light is not immediately switched off
after the run-on time (load) elapses. Triple
flashing at an interval of 10 seconds
shows that the light will be switched off
soon. The run-on time is thereby pro-
longed by approx. 30 seconds. If a move-
ment is detected by a linked JUNG
HOME sensor cover or the load switched
on again by operating an extension or by
a linked JUNG HOME operating cover
during the switch-off warning, the run-on
time is restarted and the light remains on.
Run-on time
(load)
0 s (off) ... 240 min
Default setting: Off
Ensures that the load is switched off after
the set run-on time expires instead of re-
maining permanently switched on after a
switch-on command.
If a movement is detected by a linked
JUNG HOME sensor cover during the
run-on time or the operating cover is
switched on again by operating an exten-
sion or a linked JUNG HOME operating
cover, the run-on time is restarted and the
light remains on.
The load can be switched off early during
a running run-on time only if the "Manual
switch-off during run-on time" parameter
is set to "On" or a disabling function (con-
tinuous OFF) is started.

Explanation
Manual switch-
off during run-
on time
Off, On
Default setting: On
If this parameter is set to "On", it is pos-
sible to switch off the load manually dur-
ing a current "run-on time (load)".
For an automatic staircase lighting con-
trolled by JUNG HOME operating and/or
sensor covers, this parameter should be
set to "Off" to prevent the light from being
switched off by a second person.
Presentation
function
Off, On
Default setting: Off
The presentation function is used in com-
bination with a linked JUNG HOME pres-
ence detector. The presentation function
can be switched on or off with the app or
a linked JUNG HOME push-button.
With the presentation function switched
on, the light is switched off and move-
ments detected by a JUNG HOME pres-
ence detector are prevented from switch-
ing on the light for a defined locking time.
Not only sensor signals from JUNG
HOME presence detectors, but also
sensor signals from JUNG HOME motion
detectors, switch-on and switch-off com-
mands via extensions, wireless control
with the app and other JUNG HOME
devices restart the locking time.
The presentation function is automatically
ended at the end of the locking time. Al-
ternatively, the presentation function can
be switched off manually.
Locking time
presentation
function
3 ... 240 min
Default setting: 3 min
Defines the locking time during which the
light remains off with the "presentation
function" switched on.
Sensor signals from JUNG HOME pres-
ence detectors and JUNG HOME motion
detectors, switch-on and switch-off com-
mands via extensions, wireless control
with the app and other JUNG HOME
devices restart the locking time.
