Safety instructions
▶ Read this user manual completely before installing or commissioning the
device and pay particular attention to the hazard information.
▶ The installation of this device and work on the 230 V network must only be
carried out by an electrician.
▶ The device is not a toy! Do not allow children to play with it. Never leave
the packaging material lying around unattended. Plastic film and small parts
may pose a danger to children.
▶ When remotely or automatically controlling a device, it is not always
possible to guarantee that commands are actually executed or that the correct
device status is displayed in the app and on other Smart Home display devices
because of external circumstances. This may lead to material damage and/or
personal injury. Therefore, you must ensure to the greatest extent possible
that no person is endangered at the time of remote operation or automated
control. Please take special care when setting up or adjusting the remote
control or when using the automated control and check the desired
functionality at regular intervals.
▶ Do not open up the device. It does not contain any parts to be maintained by
the user. If a fault occurs, have the device checked by a specialist.
▶ We accept no liability for material damage or personal injury which is
caused by improper use or failure to observe the safety instructions. In these
cases, any guarantee claim becomes void! We accept no liability for
consequential damage.
▶ For safety and approval reasons (CE/UKCA), the device may not be modified
and/or no changes may be made to the device without authorisation.
▶ Any use other than that which is described in the user manual is considered
improper and leads to the exclusion of guarantee and liability.
▶ The device is not suitable for disconnection.
▶ Do not use the device if it has damage visible
from the outside, for example, to the housing, control elements or connection
sockets, or if it has a malfunction. If in doubt, please contact our service
team.
▶Only operate the device indoors and do not expose it to moisture, vibrations,
constant sunlight or other sources of heat, extreme cold temperatures and
mechanical stress.
▶ Only use the device together with original components and recommended
products from Bosch partners.
Notes
▶ The range within buildings can differ significantly from the range in open
spaces. In addition to the transmitting power and the receiving properties of
the receiver, environmental factors such as humidity, as well as the local
structural situation, play an important role.
▶ The device is only suitable for use in residential environments.
▶ The device is only intended for private use.

Notes regarding installation
The standards and directives applicable in your country must be observed
during planning, set-up, operation and maintenance.
The device is part of the building installation. Operation of the device
is only permitted at 230 V/50 Hz AC voltage. Work on the 230 V network may
only be carried out by an electrician. The applicable accident prevention
regulations must be observed here. To avoid an electric shock on the device,
please switch off the mains power. Failure to observe the installation
instructions may result in fire or other hazards.
The applicable requirements must be observed during mounting. Failure to
observe the requirements may result in damage to property and/or injury, or
even danger of death.
Please also note any additional information on the product.
A 230 volt alternating current power supply is required for this product
(there must be a phase and neutral conductor).
The product is only intended for fixed installation in in-wall sockets
and junction boxes (in accordance with DIN 49073-1) in indoor areas. For in-
wall sockets, please observe the minimum depth of 50 mm and a screw distance
of 60 mm.
When connecting the device terminals, ensure that permitted wires and
wire cross sections are used.
The consumers connected to the relay outputs must have sufficient
insulation.
Observe the technical data, in particular the maximum permissible
switching power of the relay and the type of consumers to be connected, before
connecting a consumer (see technical data at the end of these instructions).
The device should only be loaded to the specified power limit. Overloading may
result in destruction of the device, fire or an electrical accident. Among
other things, reliable switching off of the connected consumer cannot be
guaranteed.
**** The power circuit to which the device and the load are connected must be
secured with a circuit breaker in accordance with EN 60898-1 (trigger
characteristics B or C, max. 16 A rated current, min. 6 kA breaking capacity,
energy limitation class 3). Installation guidelines in accordance with the
applicable national standards, e.g. VDE 0100 or HD384 or IEC 60364, must be
observed. The circuit breaker must be easily accessible for the user and
labelled as a disconnecter for the device.
Installation
Before you start: Be sure to shut off the power circuit breaker!
The device can be used to switch lamps/ lights and other electrical consumers.
The device is not suitable for disconnection.
Connect the controls in accordance with the connection diagram below:
Relay connection diagram
| Connection | Description |
|---|---|
| L | External conductor |
| N | Neutral conductor |
| S1 | Switch |
| ↑ L | Switching input |
| ↓ | Switching output |
Ensure that the terminal area does not come into contact with the metal parts
of the installed device.
**** The module may only be used outdoors with suitable protective housings.
If the module is connected correctly, switch the fuse back on.
Start-up / tuning
Ensure that you have a Bosch Smart Home controller and the Bosch Smart Home
app and have successfully configured both. Now start the Bosch Smart Home app
and select “Add new device”. Follow the instructions in the app. Once the
module has been switched on via the fuse, it is in pairing mode for 3 minutes.
Pairing mode can be started on an unlinked module by pressing the system
button (1) again or a connected switch (S1).
Resetting to factory settings
You can reset the device to its factory settings as follows: Press the system
button (1) and hold it for approx. 4 seconds until the status LED (2) flashes
orange quickly. Release the system button briefly and press and hold it again
until the LED lights green. The device then restarts. Please note that it can
take a few seconds until the module is ready for operation again.
**** WARNING Risk of electric shock. Follow the rules for live working. Only
press the system button with an isolated tool in accordance with EN IEC 60900.
Not observing these instructions can result in death or severe injuries. Work
on the 230 V network may only be carried out by an electrician.
When resetting to factory settings, the settings and information are only lost
from the device and not from the Bosch Smart Home controller.
To re-configure the device, first delete it in the device management section
of the Bosch Smart Home app and then add it again in the usual pairing
process.
