Product information

Urinal flush plate for Prevista Visign for More 200 infrared flush actuation 8 from 27

2.3.3 Operating mode

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.

Infrared actuation

Product information

Urinal flush plate for Prevista Visign for More 200 infrared flush actuation 9 from 27

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

Range of the infrared sensor

The close range is set at 0 to 3 cm.

The far range can be set as follows:

nClose range (approx. 400 mm), so that the flush cannot be inadver‐

tently actuated.

nmedium range (approx. 450 mm, factory setting)

nFar 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:
