2.3.3 Operating mode
Infrared actuation
Product information
Flush actuation takes place without contact via an infrared sensor on
the flush plate.
The flush volume can be set in four 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 2 and 15 sec‐
onds.
A flush cycle can also be manually actuated by placing a hand briefly in
front of the sensor.

Viega Hygiene+ function
24
Product information
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.
If no actuation was carried out during the set period of time, the Viega
Hygiene+ function automatically actuates a hygiene flushing.
The interval for the hygiene flushing can be set in five levels.
2.3.4 Setting options
Settings for the infrared sensor
Flush settings
Range of the infrared sensor
The close range is set at 0 to 3 cm.
The far range can be set as follows:
n Close range (approx. 400 mm), so that the flush cannot be inadver‐
tently actuated.
n medium range (approx. 450 mm, factory setting)
n Far range (approx. 490 mm), so that the automatic flush actuation
also works at a greater distance from the urinal.
Lid in front of sensor
This function is intended for the case that an open lid covers the sensor.
The function is deactivated in the factory settings. If the function is acti‐
vated, a flush cycle is actuated as soon as the lid is removed from the
sensor zone.
Viega recommends however to make sure during planning that the lid is
not placed in front of the sensor in order to guarantee perfect function‐
ality.
Flush duration
The flush duration can be set in four levels. Using the guide values from
the table below, you can determine the flush volume on the basis of
flow pressure and flush duration:
