Intended Use; Function - BWT AQA smart Einbau- Und Bedienungsanleitung

3 Intended use

AQA smart is suitable for the softening and partial
softening of drinking water and industrial water in
order to protect water pipes and the connected fit-
tings, devices, boiler, etc. from functional problems
and damage caused by limescale.
The size of the system must conform to the expected
usage conditions. You can find more information
about this in DIN 1988-200 and the technical data
section.
If the system is intended for commercial use, it must
be inspected / approved by a BWT specialist.

4 Function

System control unit depending on capacity re-
quirement
3 capacity levels can be set on the control unit
meaning the system is suitable for up to 4 resi-
dential units.
The system is preset. The presetting covers the
usual fields of usage. Readjustment is needed for
special requirements.
The system works according to the principle of
intelligent regeneration.
Intelligent volume-dependent regeneration
During commissioning, the available soft water
supply is programmed in (depending on the drinking
water hardness).
At an arbitrary time (e.g. during the night), checks
are made to determine whether the remaining soft
water supply will suffice for the next day. If not, the
softening column will regenerate only the exact
percentage required to fill the soft water supply
back up to 100%. With intelligent regeneration, no
remaining soft water supply is discarded.
This intelligent regeneration process is only possible
because a precision flow volume meter can measure
out the low volumes of brine required for partial re-
generation. The use of regenerating agent and water
is reduced to the technically required minimum.
In case of a power failure, the data and time are
preserved (approx. 1 year).
The system is equipped with a device that disin-
fects the exchanger resin during the regeneration
procedure. All water connections on the inlet side
are secured using spring-loaded return valves
(conforming to DVGW).
Automatic triggering of regeneration process
If the capacity is not exhausted within 4 days, the
electronics trigger a regeneration cycle.
The system is characterised by its compliance with
all relevant national and international standards.
