4.1 Operation
Adaptive sequential operation allows for maxi-
mum soft water availability and minimises stag-
nation in the column.
Regeneration is triggered volumetrically (depend-
ing on the quantity of water). This means that no
remaining supply of softened water is discarded
during regeneration.

water is available.
Ideally, the regeneration time occurs at night,
as water consumption is usually lower during
this period.
If the capacity falls below 50% before the query
time, proportional regeneration starts immedi-
ately.
If the capacity does not fall below 50% until after
the query time, the control system assumes that

4.2 Regeneration
Exchange of hardness forming substances Ca
and Mg ions for Na ions from the regenerative at
the ion exchanger.
A precision brine meter measures out the brine
required.
The product is equipped with a device that
disinfects the ion exchange material during
regeneration.
By measuring data acquisition during brine
extraction, the regeneration process is adapted
to the respective pressure conditions, the regen-
erative and regeneration water consumption is
reduced to the required minimum.
The optimised brine preparation process produc-
es as much brine as needed for regeneration in
less than 0.5 hours.
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.

4.6 Connectivity
BWT DES (BWT Digital Eco System)
Various functions may be available depending on
the product and market:
GSM connection to the server for full functionality
and database updates.
Wi-Fi or LAN connection to your local network to
control and monitor the product via PC, smart-
phone or tablet.
EnOcean® interface for the AQAGuard function.
Connectivity extends the functionality of the product
and allows the system to be registered in order to
use advanced operating and maintenance functions
via the
BEST WATER HOME app.
NOTE
Depending on the product, not all types
of connectivity are available.
4.7 Safety
4.7.1 AQA Safe valve
The AQA Safe valve closes the waste water
valve in the event of a power failure and thus
protects against water damage caused by rinsing
water, especially when the rinsing water is being
drained by a pump that stops functioning when
the power fails.
4.7.2 AQA Watch alarm function
The programmable AQA Watch alarm function
monitors the water supply to the building and
issues a warning message if low flow rates
(< 60 l/h) over a longer period of time (> 10 min-
utes) indicate a problem in the pipe network (e.g.
leakage, dripping drain tap or leaky toilet cistern).

5.4 Functional and warranty
conditions
Softening units require regular functional monitor-
ing, maintenance and replacement of important
parts after certain intervals.
The amounts of metering substance and regen-
erative necessary are subject to the level of con-
sumption, which depends on operating conditions.
Softening units must be cleaned regularly and also
disinfected if necessary. See this installation and
operating manual for the maintenance intervals. We
recommend that you enter into a service agreement.
