NOTE
►
The flow shown in the display indicates
the outlet water (fully softened water
plus added inflow water).

A comparison of the displayed volumes
using a domestic water meter is not
possible.

4.11 Safety
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.
In the event of a power failure, the control valves
remain in their respective operating condition.
The programmed parameters are stored perma-
nently and remain unaffected by this.
AQA Watch function
Very small volume flows (< 60 l/h) over a longer
period of time (> 10 minutes) indicate a problem in
the pipeline network (e.g. leakage, dripping drain
tap or leaky toilet cistern). The programmable AQA
Watch function of the intelligent control unit moni-
tors the water supply to the building and issues a
warning message.
AQA Stop – moisture on floor
If the product's floor sensor detects water on the
floor, the water supply in the direction of flow from
the unit is shut off and a warning issued. The floor
sensor only responds to drinking water (minimum
conductivity of 200 µS/cm).
AQA Stop – water quantity limitation
To minimise water damage, the control valve shuts
off the flow of water downstream of the product
following continuous flow of a pre-set water volume.
If larger quantities of water are to be drawn without
interruption (e.g. to fill a large whirlpool, swimming
pool etc.), this function may need to be deactivated
or acknowledged after activation. The maximum
continuous flow must be observed.
AQA Guard (optional)
Every product has a floor sensor that monitors the
floor for moisture in the immediate vicinity of the unit.
In addition,
a further 10 sensors can be wirelessly
registered with the product. When a sensor detects
moisture, the control unit gives a visual warning
signal and shuts off the water supply to the building.
When using the BWT Best Water Home app on a
mobile device, the warning is also displayed there.
