Safety advice
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.
Intended use
Areas of use
WCs in barrier-free sanitary rooms should be equipped with flush actuators 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.
INFO!
An electrical connection must be planned for the electronic actuation in the area of the cistern when planning.
Hygiene+ function
Flushes can be actuated at certain times via the Hygiene+ function to prevent stagnation in the drinking water lines.
Suitable cisterns
Installation is only possible in the following Viega concealed cisterns:
Cistern model 2H
Spülkasten Modell 2HCistern model 2L
Spülkasten Modell 2L
Ascertain which model is installed before mounting. The following information 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.
Suitable manual flush plates
Mounting of the electronic flush actuation is only possible with the following WC flush plates:

Flush volume
The flush volumes for the manual flush actuation are:
Small flush volume: 3–4 litres
Large flush volume: 6–9 litres
The following flush volumes can be set for the electronic actuation:
Large flush volume: 4.5 / 6 / 9 litres

Operating mode
Electronic actuation of a flush
A signal is sent to control the flush actuation through an external sensor, e. g. a button or photo sensor.
The control transmits the electronic signal to the drive unit.
The motor opens the drain valve via the Bowden cable.
As long as the drain valve is open, the set flush volume will flow into the WC.
Hygiene+ function
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 control. All settings remain saved during a power cut.
System expansions
The system's range of functions can be expanded through the connection of accessories onto the control.
Radio controlled actuation
One requires the following accessories to be able to connect a radio receiver – instead of a cable-connected external sensor – as shown:
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.
Additional external sensors
One requires the following accessories to be able to connect an additional external sensor as shown:
Multiple sensors can be connected at the same time using the extension cable adapter model 8350.36. This is how e. g. two external, cable-connected buttons can be connected.
Additionally required: 1 connection cable sensitive.
Buttons, switches or photo sensors for actuating the flush can be connected to the control on site via the connection cable sensitive model 8355.90.
Additional radio controlled actuation
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 extension cable adapter model 8350.36. This is how e. g. a button can be combined with a radio controlled actuation.
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.
Redundant power supply
To create a redundant power supply with an additional battery compartment 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.

Accessories
Required accessories
You require a flush plate so that the flush can be actuated directly at the WC. The Viega models that can be used are found at Suitable manual flush plates .
Optional accessories
Installation set
The set model 8350.14 contains a hollow wall socket to house the power pack and an empty pipe with the right clip to connect the cistern (2H).
Extension cable
2 metre cable model 8352.690 for the extension of the power supply to a maximum of 4.75 metres in length.
Programming set
This programming set is required to change the flush setting or activate the Hygiene+ function. It contains a connection cable with a programming contact and a magnetic pin. The programming contact is mounted behind the panel and connected to the blue terminal on the control. The programming can then take place using the magnetic pin.
Handling
Assembly information
Mounting conditions
The model may only be used for the models mentioned in Areas of use .
Installation position of the power pack
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 Optional accessories ).
If necessary, the power pack cable can be extended to a length of 4.75 metres (two extension cables Optional accessories ).
- X1 max. 0.75 m
- X2 max. 2.75 m with an extension cable (article number 628 505)
