Operating mode
Flushes from Prevista concealed cisterns are actuated electronically via the remote actuation.
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 is deactivated at the factory.
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 8570.58).
Accessories
Required accessories
For complete mounting of the electronic flush plate, you need the electronic accessory set (model 8655.11). Install the mains adapter in a connection socket suitable for protection class II (e.g. model 8570.62).
