DANGER!
Danger due to electrical current
An electric shock can lead to burns and serious injury and
even death.
– Work on the electrics may only be carried out by trained
electricians.
2.3 Intended use
2.3.1 Areas of use
WCs in barrier-free sanitary rooms should be equipped with flush actua‐
tors that can be easily reached by users and carers. For this purpose,
the flush plate of the WC can be combined with a radio-controlled or
cabled sensor using an electronic flush actuation. A sensor such as this
can be fitted on e. g. the handles of the WC or in any position in the
room.
Product information
WC flush actuation 6 from 48

An electrical connection must be planned for the electronic
actuation in the area of the cistern when planning.
Flushes can be actuated at certain times via the Hygiene+ function to
prevent stagnation in the drinking water lines.
Installation is only possible in the following Viega concealed cisterns:
nCistern model 2H
nCistern model 2L
Ascertain which model is installed before mounting. The following infor‐
mation will help you to determine the model of the cistern installed:
Cistern 2H
The revision shaft of this cistern is found at a height of approx. 1 metre
on the front.
Cistern 2L
The revision shaft of this cistern is either found at a height of approx.
75 cm on the front or on the top.
Mounting of the electronic flush actuation is only possible with the fol‐
lowing WC flush plates:
Hygiene+ function
Suitable cisterns
Suitable manual flush plates

Fig. 2: Actuation of the flush via an external sensor
A signal is sent to control the flush actuation through an external sensor,
e. g. a button or photo sensor.
Fig. 3: Signal transmission from the control to the motor
The control transmits the electronic signal to the drive unit.
Fig. 4: The motor operates the Bowden cable
The motor opens the drain valve via the Bowden cable.

Product information
WC flush actuation 10 from 48

Fig. 5: The water flows into WC via the open drain valve
As long as the drain valve is open, the set flush volume will flow into the
WC.
Stagnation can lead to the build up of germs (e. g. legionella) in drinking
water pipes. It is important to rinse the pipeline regularly to prevent the
build up of bacteria. The Viega Hygiene+ function was developed for
this reason.
Flushes can be actuated at certain times with the Hygiene+ function.
Interval and flush volume will be set as required and saved by the con‐
trol. All settings remain saved during a power cut.
2.4.4 System expansions
The system's range of functions can be expanded through the connec‐
tion of accessories onto the control.
Fig. 6: Connection of the radio receiver
One requires the following accessories to be able to connect a radio
receiver – instead of a cable-connected external sensor – as shown:
Hygiene+ function
Radio controlled actuation
Product information
WC flush actuation 11 from 48

Signals to actuate the flush (e. g. on support hinged handles) sent by
HEWI radio transmitters can be received by the radio receiver model
8350.35.
Fig. 7: Connection of a second external button
One requires the following accessories to be able to connect an addi‐
tional external sensor as shown:
Multiple sensors can be connected at the same time using the exten‐
sion cable adapter model 8350.36. This is how e. g. two external, cable-
connected buttons can be connected.
Additional external sensors
Product information
WC flush actuation 12 from 48

nected to the control on site via the connection cable sensitive model
8355.90.
Fig. 8: Connection of radio and cable sensors
One requires the following accessories to be able to connect a radio
controlled actuator alongside an external sensor as shown:
Multiple sensors can be connected at the same time using the exten‐
sion cable adapter model 8350.36. This is how e. g. a button can be
combined with a radio controlled actuation.
Additional radio controlled actuation

The model may only be used for the models mentioned in Ä Chapter
2.3.1 „Areas of use“ on page 6.
The power pack should be mounted in an easily accessible place to
allow subsequent access.
Before beginning to tile, a concealed socket should be installed for the
power pack with protective pipe to the cistern (installation set
Ä „Optional accessories“ on page 15).
If necessary, the power pack cable can be extended to a length of
4.75 metres (two extension cables Ä „Optional accessories“
