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

Flushes can be actuated at certain times with the function.
Interval and flush volume will be set as required and saved by the con‐
trol. All settings remain saved during a power cut.
