2.3 Intended use

2.3.1 Areas of use

WCs in barrier-free sanitary rooms should be equipped with flush actua‐ tors 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.

Hygiene+ function

Suitable cisterns

Product information

An electrical connection must be planned for the electronic actuation in the area of the cistern when planning.

Flushes can be actuated at certain times via the Hygiene+ function to prevent stagnation in the drinking water lines.

Installation is only possible in the following Viega concealed cisterns:

n Cistern model 2H n Cistern model 2L

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 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 fol‐ lowing WC flush plates:

Flush volume

Product information

The product has the following technical data:

The flush volumes for the manual flush actuation are:

n Small flush volume: 3–4 litres n Large flush volume: 6–9 litres

The following flush volumes can be set for the electronic actuation:

n Large flush volume: 4.5 / 6 / 9 litres n Small flush volume: 3 / 4 litres

If the external sensor (e. g. a remote button on the handle) offers two activation options, the electronic actuation can be used to select between the large or small flush volume.

Electronics

Electronic actuation of a flush

Product information

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. 5: The water flows into WC via the open drain valve

As long as the drain valve is open, the set flush volume will flow into the WC.

Hygiene+ function

2.4.4

System expansions

Radio controlled actuation

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 con‐ trol. All settings remain saved during a power cut.

The system's range of functions can be expanded through the connec‐ tion of accessories onto the control.

Fig. 6: Connection of the radio receiver

One requires the following accessories to be able to connect a radio receiver – instead of a cable-connected external sensor – as shown:

WC flush actuation 11 from 48

Page 12

Additional external sensors

Product information

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.

Fig. 7: Connection of a second external button

One requires the following accessories to be able to connect an addi‐ tional external sensor as shown:

Multiple sensors can be connected at the same time using the exten‐ sion cable adapter model 8350.36. This is how e. g. two external, cableconnected buttons can be connected.

Additional radio controlled actuation

Product information

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.

Fig. 8: Connection of radio and cable sensors

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 exten‐ sion cable adapter model 8350.36. This is how e. g. a button can be combined with a radio controlled actuation.
