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.
The system's range of functions can be expanded through the connec‐
tion of accessories onto the control.

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.
