5.1 Planning instructions
Note
Planning and application instructions for the system are available in system
manual for Busch-free@home®. This can be downloaded via .
Note
Transmitter and receiver communicate via radio control. The transmission range
depends on the structural conditions. Walls and ceilings, especially steel
reinforcements or metal claddings, reduce the transmission range. The distance
of components to each other and to other transmitters that also emit high-
frequency signals (e.g. computers, audio and video systems) should be at least
1 m.

5.2 Safety instructions
Danger - Electric shock due to short-circuit!
Risk of death due to electrical voltage of 100 … 240 V during short-circuit in the
low-voltage conduit.
– Low-voltage and 100 … 240 V conduits must not be installed together in a
flush-mounted box!
– Observe the spatial division during installation (> 10 mm) of SELV electric
circuits to other electric circuits.
– If the minimum distance is insufficient, use electronic boxes and insulating
tubes.
– Observe the correct polarity.
– Observe the relevant standards.
Danger - Electric voltage!
Install the device only if you have the necessary electrical engineering
knowledge and experience.
■ Incorrect installation endangers your life and that of the users of the
electrical system.
■ Incorrect installation can cause serious damage to property, e.g. due to fire.
The minimum necessary expert knowledge and requirements for the installation
are as follows:
■ Apply the "five safety rules" (DIN VDE 0105, EN 50110):
1. Disconnect
2. Secure against being re-connected
3. Ensure there is no voltage
4. Connect to earth and short-circuit
5. Cover or barricade adjacent live parts.
■ Use suitable personal protective clothing.
■ Use only suitable tools and measuring devices.
■ Check the type of supply network (TN system, IT system, TT system) to
secure the following power supply conditions (classic connection to ground,
protective earthing, necessary additional measures, etc.).
■ Observe the correct polarity.

Commissioning

6 Commissioning
Commissioning of the device is always carried out via the Web-based surface of the System
Access Point. It is assumed that the basic commissioning steps of the overall system have
already been carried out. Knowledge about the Web-based commissioning software of the
System Access Point is assumed.
The System Access Point establishes the connection between the free@home participants and
the smartphone, tablet or PC. The System Access Point is used to identify and program the
participants during commissioning.
When energized, a device that has not been programmed is in programming mode for 30
minutes and can be logged into the system. Programmed devices share information about their
type and supported functions with the System Access Point.
During initial commissioning all devices are given a universal name (e.g. sensor/switch actuator,
sensor/dimming actuator, sensor/blind actuator, room temperature controller, movement
detector, etc.). The installer must change this name within the commissioning process to a
name practical and specific for the system (in case of an actuator, e.g. to "Living room ceiling
light").
The devices must be parameterised for the use of additional functions.
Notice
General information about commissioning and parameterization is available in
the Busch-free@home® system manual.

6.1 Coupling of wireless devices with the System Access Point
free@home wireless devices must first be coupled with the System Access Point before they
can be used in a project. The devices exchange a security key during the coupling process.
Communication between devices is carried out encrypted after coupling and they are firmly
connected with the System Access Point. Coupled devices cannot be connected with a different
System Access Point. They must first be reset to the factory settings.
Carry out the following steps to couple one or several devices with the system:
1. Install the free@home wireless device(s).
2. Use your smartphone, tablet or PC to call up the user interface of the System Access Point
that is ready for use.
3. Switch on the mains power supply of the free@home wireless devices.
The devices are now in programming mode for 30 minutes.
Fig 11: Coupling wireless devices with the System Access Point
4. In the user interface of the System Access Point select "System settings" → "free@home-
Wireless settings" → "Search for wireless devices".
The System Access Point consecutively scans all free@home-Wireless channels. Devices
that are in programming mode are automatically integrated into the system. The scanning
process ends 10 minutes after the last device has been found.
Integrated devices are listed in the "Device list" of the user interface.
5. Use the serial numbers to check whether all installed devices have been found.
If a device has not been found, reset it to the factory settings and start a new scanning
process.
Possible reasons for not finding devices:
■ The device is not in programming mode.
■ The 30-minute programming time has expired.
■ The device has already been coupled with a different system.
6.1.1 Resetting the wireless device to the factory settings
1. Switch the free@home wireless device off.

6.2 Allocation of devices and definition of channels
The devices connected to the system must be identified, i.e. they are allocated to a room
according to their function and are given a practical name.
The allocation is made via the device function of the Web-based user interface
of the System Access Point.
6.2.1 Add device
1. In the "Add devices" bar select the desired application and pull it via drag-and-drop into the
floor plan.
Fig. 12: Dragging the application from the add bar
A pop-up window opens which lists all the devices that are connected to the bus and suitable for
the selected application.
