2.4.3 Operating mode
Flush actuation takes place without contact via the infrared sensor on
the flush plate.
The flush volume can be set in five stages.
In order to actuate a flush, a person must be within the detection area of
the infrared sensor for at least 8 seconds.
If a person leaves the detection area, a flush is automatically actuated.
Depending on the setting, the flush duration is between 1 and 20 sec‐
onds.
A flush cycle can also be manually actuated by placing a hand in front
of the sensor during the first 8 seconds.

Stagnation can lead to the build up of germs (e.g. legionella) in potable
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.
The Viega Hygiene function automatically actuates hygiene flushing
after 24 hours without use. The flush volume of the Hygiene flush can be
set in five stages.
2.4.4 System expansions
The system's range of functions can be expanded through the connec‐
tion of accessories onto the control.
Fig. 2: Connection of an external sensor
Buttons, switches or photo sensors for triggering the flush can be con‐
nected to the control on site via the extension cable model 2241.95.
The cartridge valve remains open as long as the contact via the exten‐
sion cable is closed.
The overflow protection prevents that the cartridge valve remains open
for longer than a minute. The contact must be re-opened to enable a
further flush.

The battery compartment model 8351.11 (article number 731 786) can
also be connected as an alternative to the power pack.
2.4.5 Setting options
Range of the infrared sensor
The following settings are possible:
nClose range, so that the flush cannot be inadvertently actuated.
nMedium range from approx. 450 mm. This setting is the factory set‐
ting.
nFar range, so that the automatic actuation of a flush also works at a
greater distance from the urinal.
Manual flush in close range
If this option is activated, a flush can be actuated in the first 8 seconds
of entering the detection area by placing a hand in front of the sensor.
Lid in front of sensor
This setting is for the case that an open lid covers the sensor. The func‐
tion is deactivated in the factory settings. If the function is activated, a
flush cycle is actuated as soon as the lid is removed from the sensor
zone.
However, during planning, we still recommend that the lid is not placed
in front of the sensor in order to ensure the device works perfectly.
Flush duration
This setting is intended exclusively for the flush duration for the directly
actuated flushes. The flush duration for hygiene flushes is set sepa‐
rately.
The flush duration can be set in 5 steps to reach the required flush
volume.
Hygiene flush
The setting determines if a hygiene flush is actuated after 24 hours
without use.

3.1 Assembly information
3.1.1 Mounting conditions
If external sensors are to be connected to the control, their connection
cables must be laid through to the revision opening before tiling is
begun.
The following minimum distances must be complied with to ensure the
infrared sensor works perfectly:
A minimum distance of 1000 mm must be maintained to the opposite
walls.
If high-gloss wall claddings (polished tiles, mirrors, etc.) are situated
opposite, increase the minimum distance to 1500 mm.
A minimum distance of 1500 mm must be maintained to urinals situated
opposite with infrared sensors.
