● The brine collects in a special sink of the regen-
erative container and is fully extracted from there.
After brine extraction, there is no liquid left in the
regenerative container.
● An ultrasound sensor in the Easy Fill technology
cover measures the regenerative level.
● The regeneration is proportional. 100% regener-
ation takes place after 72 hours at the latest for
hygiene purposes.
4 3 Regenerative monitoring
● 100% in the multi-info touch display corresponds
to a regenerative filling level of approx. 46 cm.
● From a level of around 20%, the device status
indicator changes from “blue” to “yellow” to signal
a need to refill the regenerative.
4 4 Multi-info touch display
The product is equipped with a touch display. It
can be operated intuitively and provides a quick
overview of all product parameters.
During start-up, you can select basic parameters
on the display:
● Country-specific settings at the location of
operation
● Unit for measuring water hardness at the loca-
tion of operation (°dH, °f, mol/m
3
, ppm calcium
carbonate)
● Inflow water hardness (enter manually or input the
value stored in the hydromaps water hardness
database for the location of operation)
● Desired outlet water hardness
Depending on your settings, you will see the current
parameters on the display during operation:
● Current flow volume in l/h (fully softened water
plus inflow water)
Outlet water
= flow volume in l/h
Inflow water
Blending valve
Fully softened water
= displayed volume in litres
