description
3.1 Component of the ambiSENSE
system
The product is part of the ambiSENSE
room climate solution and communicates
via a radio protocol. All products in the
ambiSENSE room climate solution can be
configured via the VRC 700 app using a
smartphone.
You can use the ambiSENSE repeater to
expand the range of the ambiSENSE radio
network in order to ensure the communi-
cation connection between the
ambiSENSE units throughout the entire
flat or house. If you are using ambiSENSE
units outside of the direct range of the
radio network, e.g. in the cellar or on the
top floor of the building, the ambiSENSE
repeater provides support when transmit-
ting radio commands. You can use up to

two ambiSENSE repeaters in the
ambiSENSE system. The product is easily
paired to the VR 920 Internet gateway.

3.3 Radio operation
The radio signal is transmitted on a
non-exclusive transmission path. Faults
can therefore not be ruled out. Interfer-
ences may, for example, be caused by
switching operations, electric motors or
defective electrical units.
The range inside buildings may differ con-
siderably from the range outdoors. Except
for the transmission power and the recep-
tion properties of the transceivers, envi-
ronmental influences (such as air humidity
and structural elements) play an important
role on-site.

3.5 Duty cycle limit
The duty cycle limit describes a legally
regulated limit on the transmission time of
units in the 868 MHz range. The aim of
this regulation is to guarantee that all
units that work in the 868 MHz range
work correctly. In the frequency range 868
MHz that is used by the product, the maxi-
mum transmission time for each individual

unit is 1% of an hour (i.e. 36 seconds in
1 hour). The product complies with this
directive.
In normal mode, the duty cycle limit is not
normally reached. In individual cases, e.g.
during start-up or the new installation of a
system, increased and radio-intensive pair-
ing processes may mean that this limit is
not reached. If the duty cycle limit is
exceeded, the signal LED lights up red for
one extended period and may indicate that
a function is temporarily missing from the
product. After a short time (max. one
hour), the product’s function is restored.
3.6 CE marking
The CE mark shows that the products
comply with the basic requirements of the

applicable guidelines as stated on the data
plate.
The manufacturer hereby declares that the
type of radio equipment that is described
in these instructions complies with Direc-
tive 2014/53/EU. The complete text for the
EU Declaration of Conformity is available
at: http://www.vaillant-group.com/doc/

4 Integration into the
ambiSENSE system
4.1 Pairing
To ensure that the ambiSENSE repeater is
integrated into the ambiSENSE system
and can communicate with other
ambiSENSE units, it must first be paired
to the VR 920 Internet gateway. You
should therefore first set up the VR 920
Internet gateway via the VRC 700 app in

order to be able to use other ambiSENSE
units in the system.
Then pair the product via the VRC 700
app.
>Open the VRC 700 app on the smart-
phone.
>Select Settings on the bottom right.
>Select ambiSENSE.
>Select Add Repeater.
>Follow the installation assistant.
