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.
4.5
Multi-info touch display
A fully graphical, 5-inch full cap touch display is
used for display and for controlling the product.
The device status is displayed via the BWT logo.
During start-up, the proposed inflow water hardness
from the HYDROMAPS database can be adopted
or the hardness of the local drinking water and the
desired outlet water hardness can be entered into
the control unit.
All other product parameters are stored in the
control unit. All product data is pre-set and product
parameters can be queried.
The product capacity is displayed as a flow volume
in l/h during operation.
Operating data, such as water and regenerative
consumption, can be displayed on screen.
The following country-specific settings are available:
DE, AT, CH, EN, FR, IT, ES.
Water hardness in: °dH, °f, mol/m
3
, ppm calcium
carbonate.
A memory function for filter backwashing or a filter
change can be programmed in the control unit.

Stagnation management
Depending on the capacity consumption, the
product performs a proportional regeneration or a
hygiene rinse at the time of regeneration.
If the capacity is not used up within 72 hours, the
control unit triggers a regeneration.
4.7
Display of flow rates
(volumes)
The accumulated water consumption indicates the
consumption of fully softened water.
4.2
Operation
The mode of operation is consumption-dependent.
This adaptive, sequential design maximises sof-
tened water availability and minimises stagnation.
During the regeneration process, untreated inflow
water is available.
The regeneration time therefore occurs at night,
as water consumption is usually lower during this
period.
The product automatically determines the capacity
required through constant monitoring over a two-
week consumption period.
During operation, the mineral substance is metered
in proportion to the through-flow. The water is thus
supplemented with the corrosion-inhibiting mineral
substance phosphate. This raises the phosphate
concentration in the outflow water by about 1.5 mg/l.
Regeneration begins immediately if the capacity is
exhausted; otherwise it starts at the regeneration
time.
4.3
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 extrac-
tion, the regeneration process is adapted to the
respective pressure conditions, the regenerative
and regeneration water consumption is reduced to
the required minimum.
The optimised brine preparation process produces
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.
