2.3 Intended use
2.3.1 Areas of application
A flush plate with infrared sensor in public or barrier-free sanitary rooms
offers a practical and hygienic possibility to actuate a flush for users and
carers. In addition, there is the possibility to connect radio controlled or
cabled sensors to the electronic flush actuation, so that e. g. carers can
actuate the flush from a convenient position, without having to be in the
vicinity of the infrared sensor.
An electrical connection must be planned for the elec‐
tronic actuation in the area of the cistern when planning.
Only the large flush volume can be actuated with elec‐
tronic actuation.
Flushes can be actuated at certain times via the Viega Hygiene function
to prevent stagnation in the potable water pipelines.
The flush plate is intended for touchless flush actuation of flushes on
Viega concealed cisterns.
Installation is only possible in the following Viega concealed cisterns:
nCistern model 2H
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 inspection shaft of this cistern is found at a height of approx.
1 metre on the front.

Product information
Flush plate Visign for Public 5 7

The large flush volume is always used when flushing is actuated man‐
ually using the plate. The flush volume is 6–9 litres.
Depending on the setting ( Ä ‘Settings for the infrared sensor’
on page 14), the infrared sensor automatically selects between the
small or large flush volume.
With electronic actuation, only the large flush volume of 6 or 9 litres can
be actuated.
Close range 0–30 mm
Far range 450–550 mm
Input (mains adapter) 100–240 V AC, 50–60 Hz, 180 mA
Output (mains adapter) 6.5 V DC, 920 mA
Electrical approvals see section Ä ‘Regulations from sec‐
tion: Technical data’ on page 5.

2.4.3 Operating mode
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
Flush plate Visign for Public 5 10

Flush actuation takes place without contact via an infrared sensor on
the flush plate. This sensor differentiates between a close and a far
range.
a: Far range (blue) 450–550 mm
b: Close range (red) 0–30 mm
A flush can be actuated by holding a hand in front in the close range.
If a person stands in the long-distance range for more than 8 seconds,
the flush actuation using the close range is automatically deactivated.
This prevents an unwanted flush actuation.
After the flush is actuated, the close range sensor can then be used to
actuate a second flush by hand.
If a person leaves the far range, a flush is automatically actuated.
After use, an additional flush cycle can be actuated through the close
range sensor.
Stagnation can lead to the build up of germs (e.g. legionella) in potable
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 Viega Hygiene func‐
tion. Interval and flush volume will be set as required and saved by the
control. 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 redundant power supply
To create a redundant power supply with an additional battery compart‐
ment as shown, you will need the following accessories:
The battery compartment can be connected for a redundant power
supply using the adapter model 8355.91. The battery compartment is
included in the adapter's scope of delivery.

One requires the following accessories to be able to connect an addi‐
tional external sensor as shown:
With the extension cable adapter model 8350.36, an additional sensor
can be connected to the infrared sensor.
Additionally required: 1 connection cable sensitive.
Buttons, switches or photo sensors for actuating the flush can be con‐
nected to the control on site via the connection cable sensitive model
8355.90.

One requires the following accessories to be able to connect the
infrared sensor alongside a radio controlled actuation as shown:
With the extension cable adapter model 8350.36, an additional sensor
can be connected to the infrared sensor.
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.
2.4.5 Setting options

The far range can be set as follows:
nclose range (approx. 450 mm)
nmedium range (approx. 500 mm) (factory setting)
nfar range (approx. 550 mm)
Lid in front of sensor
This setting is for the case that an open lid covers the sensor. The func‐
tion is deactivated in the factory settings. If the function is activated, a
flush cycle is actuated as soon as the lid is removed from the sensor
zone.
However, during planning, we still recommend that the lid is not placed
in front of the sensor in order to ensure the device works perfectly.
For electronically actuated flush cycles (including Hygiene
flushes), only large flush volumes of 6 or 9 litres can be
actuated for technical reasons although the programming
also provides for smaller flush volumes. If smaller flush
volumes are set, the flush is always actuated with the
smallest flush volume of 6 litres.
Flush volume
This criterion relates exclusively to the flush volume for flush cycles
actuated electronically. The flush volume for hygiene flushes is set sep‐
arately.
The following settings are possible:
n4.5 litre flush volume (the flushes are always with the smallest flush
volume of 6 l) for technical reasons
n6 litre flush volume (factory setting)
n9 litre flush volume
Interval (Viega Hygiene function)
The following settings are possible:
nHygiene function deactivated (factory setting)
nHygiene flush 24 hours after the last use
nHygiene flush 72 hours after the last use
nHygiene flush 168 hours after the last use
Hygiene (Viega Hygiene function)
The following settings are possible:
nHygiene flush volume 3 litres (factory setting) (for technical reasons,
the flushes occur with the smallest possible flush volume of 6 l)
nHygiene flush volume 6 litres
nHygiene flush volume 9 litres

The model may only be used for the models mentioned in Ä Chapter
2.3.1 ‘Areas of application’ 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
