2.2 Intended use
The ABB-free@home®flex touch control device is a combination of flex flush-mounted insert
(actuator) and flex control element. The device elements must only be combined with each
other within the product group of ABB-free@home®flex. A combination with switch inserts or
control elements of other manufacturers is not possible.
The following actuators or inserts can be combined with control elements 64711-WL and 64721-
WL:
■The switch actuators 64811 U-500 and 64821 U-500 serve for switching lighting systems.
■Switch actuator 64814 U-500 is planned for installation in systems without neutral
conductors and serves for switching lighting systems.
■Sub-insert 64891 U-500 can be physically combined with the different flexTronic inserts, e.g.
on a Relay insert flex, 1 gang. Up to nine subs can be combined with a main. The maximum
total cable length amounts to 100 meters.
■Dimming actuator 64851 U-500 serves for dimming and switching of lighting.
■Blind actuator 64831 U-500 serves for the control of roller blinds, blinds or awnings.
The ABB-free@home®flex control devices are designed for dry interior areas. Mounting is
permitted only in commercially available device boxes according to DIN 49073 (e.g. ABB FM
box brickwork (article no. 3040), FM box hollow wall (article no. 3050) or FM box concrete
(article no. 3060)).

6.2 Mounting / dismantling
Caution! The device can sustain damage when coming into contact with
hard objects!
The plastic parts of the device are sensitive.
– Pull the attachment off only with your hands.
– Do not lever parts off with screwdrivers or similar hard objects.
6.2.1 Mounting possibilities
The wall mounting / ceiling mounting of the flush-mounted inserts takes place in a standard
flush-mounted box or device box. The following mounting situations are possible, for example:
Wall mounting
■Stone walls
■Plaster walls
■Hollow walls
■Insulated walls
The devices are not suitable for:
■Purely surface mounting
If a flush-mounted installation is not desired or not possible, the flush-mounted inserts can also
be mounted in surface-mounted housings for flush-mounted inserts.
All ABB flexTronics®/ ABB-free@home®flexdevices are mounted or disassembled the same
way.
To install the device combination, perform the following steps:
Attention! ‒Malfunction
Do not attach or change the control element when the insert is under voltage.
This can lead to malfunctions.

Commissioning
Product manual 2CKA001473B5285

20
7 Commissioning
The following prerequisites and system limits apply for commissioning the Weather station flex,
wireless.
Prerequisites
■Operation and configuration app "ABB-free@home®App Next"
■Registration at MyBuildings
■Depending on the desired expansion stage of the operating mode, additional components
are required.
– Room control: Additional ABB-free@home®flex devices for the setup of a mesh network
are necessary.
– Home automation (SysAP): For integration in ABB-free@home®installation with a
System Access Point.
■Setup of radio network: Several devices must be available and they must be visible
together, see .
System limits
■Bluetooth®:
– The radio range between the devices amounts to a maximum of 10 meters.
– A Bluetooth®connection is used for the connection between the smartphone and an
additional device. If thick walls are located within the planned radio line, the attainable
transmission ranges are greatly reduced.
– The same applies to connections on other floors. In this case the radio signals must
pass through floor ceilings.
■Wireless 2.4 GHz:
– The radio range between the devices amounts to a maximum of 30 meters.
– If thick walls are located within the planned radio line, the attainable transmission ranges
are greatly reduced.
– The same applies to connections on other floors. In this case the radio signals must
pass through floor ceilings.
Special measures for commissioning are not required. The ABB-free@home®flex device is
ready for operation directly after connection and assembly.
The function of the respective device depends on the combination of ABB flexTronics®insert
and ABB-free@home®flex control element.
– If the sensor shows 1 rocker, the rocker is linked with the actuator function via default
(dimming, switching, blind).
– If the sensor shows 2 rockers (2gang sensor), the left rocker is linked with the actuator
function via default (dimming, switching, blind).
The right rocker has no function via default.
The further parameter setting is carried out via the ABB-free@home®App Next or the System
Access Point. Here both rockers can be freely linked and occupied with functions, e.g. for blind
control, see “Operation“ on page 44.
