3.3 Functional description
3.3.1 Ion exchange process
The softliQ water softener works according to the ion exchange process. The exchange of
calcium and magnesium ions for sodium ions causes the water to become soft.
Figure Explanation
The exchanger contains ion exchanger resin in the form of small resin
beads.
Sodium ions adhere to each resin bead.
Hard water containing lots of calcium and magnesium ions flows through
the exchanger.
The ion exchanger resin absorbs calcium and magnesium ions from the
water in exchange for sodium ions.
This reaction is called ion exchange.
The calcium and magnesium ions are retained in the exchanger.
Soft water without calcium and magnesium ions, but containing sodium
ions, leaves the exchanger.
This process continues until no more sodium ions are available. The ion
exchanger resin is exhausted.
The exchange can be reversed if a large amount of sodium ions is
added.
The exchanger is flushed with brine (water containing salt).
By their sheer number, sodium ions displace calcium and magnesium
ions on the ion exchanger resin.
This water containing calcium and magnesium ions is discharged to the
drain.
The initial condition is restored.
The ion exchanger resin is regenerated, and thus ready for operation.
Sodium ion Calcium ion Magnesium ion
Your dishwasher works according to the ion exchange process, too.

3.3.2 Intelligence of the softliQ:SC water softener
Based on the consumption values of the past three days, the system capacity is
automatically adjusted to the individual water consumption of the owner/user. The water
softener softliQ:SC offers two selections. The energy and resource saving Eco Mode is set
by the factory. In case of considerable fluctuations in the water consumption, however, it is
possible to switch to the Power mode in the settings menu. The currently set mode is
displayed in Information menu 1.
A regeneration is released daily, if at least 50 % of the current system capacity is used up.
The point of regeneration automatically is placed in a time period where usually no water is
consumed. The point of regeneration can also be set at a fixed time. Should water be
required during the regeneration process, non-softened water is available.
During each regeneration, only the used-up system capacity is regenerated and only as
much salt is used as necessary. For hygienic reasons, the system releases a complete
regeneration after four days at the latest, as required by DIN standard 19636-100.
The intelligence of the softliQ water softener allows for an efficient operation at the lowest
salt and power consumption possible.
3.4 Response behaviour
● Eco mode
Resource and energy-saving operating mode for households with a consistent
withdrawal profile.
● Power Mode
Optimised provision of soft water for households in which the withdrawal profile
fluctuates considerably.
3.5 Optional features for softliQ:SC23
3.5.1 Pre-alarm salt supply
Once per regeneration, a light sensor briefly checks the filling level of the regeneration salt. If
the filling level is below the minimum, the control unit provides feedback in the form of a
warning message. This is indicated by a yellow symbol in the control unit. After the minimum
filling level is being undershot, the control unit of the softliQ:SC23 calculates how many days
the salt supply is expected to last, and indicates this value in days in the warning message.
The days the salt supply is expected to last are calculated based on the water consumption
of the past days. In case of fluctuating water consumption, the indicated range of the salt
supply also fluctuates.

3.5.2 Illuminated LED ring
The illuminated LED ring is used as a visual signal during water treatment, operation and
malfunction. In the standard setting, the illuminated LED ring behaves as follows:
● Lights up during water treatment
● Lights up during operation of the control unit
● Intermittent flashing in case malfunctions do occur
● Intermittent flashing in case of pre-alarm salt supply
If required, the LED ring can be set to light up continuously or be completely deactivated
