Intended use
Areas of use
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 caregivers. In addition, there is the possibility to connect radio controlled or cabled sensors to the electronic flush actuation.
INFO!
An electrical connection must be planned for the electronic actuation in the area of the cistern when planning.
Only the large flush volume can be actuated with electronic flush actuation.
Suitable cisterns
The flush plate is intended for the actuation of flushes on Viega concealed cisterns.
Installation is possible in all Prevista concealed cisterns.

Technical data
Flush volume
The flush volumes for the flush actuation are:
Small flush volume: approx. 2 / 3 / 4 litres
Large flush volume: approx. 3.5 / 4.5 / 6 / 7.5 litres
Depending on the setting ( Setting the infrared sensor ), the infrared sensor automatically selects between the small or large flush volume.
If the external sensor (e. g. a remote button on the handle) offers two activation options, the electronic flush actuation can be used to select between the large or small flush volume.

Operating mode
Flushes from Prevista concealed cisterns are actuated contact-free via the flush plate. The sensor range is approx. 0‑30 mm from the flush plate.
Optionally, a large or small flush volume can be flushed.
Infrared actuation
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) 400–600 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.
If the long range is left within a definable time frame (30, 60 or 90 seconds), the small flush volume is used. If a person stays for longer, a flush with the large flush volume takes place.
After use, an additional flush cycle can be actuated through the close range sensor.
Viega Hygiene function
Stagnation can lead to the build up of germs (e.g. legionella) in potable water pipelines. 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 are actuated in a time-controlled manner with the Viega Hygiene function. Interval and flush volume will be set as required and saved by the control. All settings remain saved during a power cut.
The function is deactivated at the factory.
System expansions
The system's range of functions can be expanded through the connection of accessories onto the control.
Setting options
Settings for the infrared sensor
Range of the infrared sensor
The close range is set at 0 to 30 mm.
The far range can be set as follows:
close range (approx. 400 mm)
medium range (approx. 500 mm) (factory setting)
far range (approx. 600 mm)
To set the range of the infrared sensor, see Setting the range .
Differentiation of small and large flush volume
The differentiation between small and large flush volume takes place automatically depending on how long the WC is used. The differentiation is deactivated in the factory settings.
The following settings are possible:
Differentiation of small and large flush volume deactivated. This setting is the factory setting.
Large flush volume in the case of use of longer than 30 seconds.
In the case of shorter use the small flush volume is used.
Large flush volume in the case of use of longer than 60 seconds.
In the case of shorter use the small flush volume is used.
Large flush volume in the case of use of longer than 90 seconds.
In the case of shorter use the small flush volume is used.
To set the flush volume of the infrared sensor, see Setting the differentiation of small and large flush volumes .
WC lid in front of sensor
This setting is provided for cases where an open WC lid covers the sensor. The function is deactivated in the factory settings. If the function is activated, a flush cycle is actuated as soon as the WC lid is removed from the sensor zone.
Viega recommends however to make sure during planning that the lid is not placed in front of the sensor in order to guarantee perfect functionality.
To set the "WC lid in front of the sensor" function, see Setting the "WC lid in front of sensor" .
Flush settings
To set the flush volumes, see Setting the flush .
Flush volume
This criterion relates exclusively to the flush volume for flush cycles actuated electronically. The flush volume for hygiene flushing is set separately.
The following settings are possible:
Small flush volume 3 litres, large flush volume 4.5 litres
Small flush volume 3 litres, large flush volume 6 litres (factory setting)
Small flush volume 4 litres, large flush volume 9 litres
Interval of the Hygiene function
The following settings are possible:
Hygiene function deactivated (factory setting)
Hygiene flush 24 hours after the last use
Hygiene flush 72 hours after the last use
Hygiene flush 168 hours after the last use
Flush volume of the Hygiene function
The following settings are possible:
Hygiene function, 3 litres flush volume (factory setting)
Hygiene function, 7.5 litres flush volume
