Viega Hygiene function
Flush plate Visign for Public 6
Flush actuation takes place without contact via an infrared sensor on
the flush plate. This sensor differentiates between a close and a far
range.
a: Far range (blue) 450–550 mm
b: Close range (red) 0–30 mm
A flush can be actuated by holding a hand in front in the close range.
If a person stands in the long-distance range for more than 8 seconds,
the flush actuation using the close range is automatically deactivated.
This prevents an unwanted flush actuation.
After the flush is actuated, the close range sensor can then be used to
actuate a second flush by hand.
If a person leaves the far range, a flush is automatically actuated.
If the long range is left within a definable time frame (30, 60 or 90 sec‐
onds), the small flush volume is used. If a person stays for longer, a
flush with the large flush volume takes place.
After use, an additional flush cycle can be actuated through the close
range sensor.
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.
Flushes can be actuated at certain times with the Viega Hygiene func‐
tion. Interval and flush volume will be set as required and saved by the
control. All settings remain saved during a power cut.
