JUNG HOME switch actuator 1-gang mini with 2 binary inputs
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.
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 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.

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
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.
