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
For the setting of the flush see Setting the flush .
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 0‑30 mm from the flush plate.
Optionally, a large or small flush volume can be flushed.
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 can be disabled.
System expansions
The system's range of functions can be expanded through the connection of accessories onto the control.
Radio controlled actuation
You need the following accessories to connect a radio receiver instead of a cable-connected external sensor:
Signals to actuate the flush (e. g. on support hinged handles) sent by HEWI radio transmitters can be received by a radio receiver (model 8350.35).
Accessories
Required accessories
For complete mounting of the electronic flush plate, you need the electronic accessory set (model 8655.11).

Setting the flush
INFO!
The smallest possible flush volume must be set at the drain valve in the cistern.
The flush volume is set via the DIP switches of the control.
- A Setting of the flush volume
- B Interval of the Viega Hygiene+ function
- C Setting the flush volume of the Viega Hygiene+ function
- 0 DIP switch position: OFF
- 1 DIP switch position: ON
