Salt efficiency (reduced salt
consumption) mode
When the salt efficiency (reduced salt
consumption) mode is
ON, the device
will run the regeneration process more
often, consuming less salt and water
for the process. The use of salt
efficiency mode will depend on the
quality of water used in the
household.
Setting of this function can only be
implemented by the service team of

water contains increased amounts of
impurities such as sand, sludge,
slurry, etc., the duration of cleaning
may be extended to a maximum of 15
minutes. In order to change the value
on the display screen, press the

button to reduce cleaning duration
time or the
▼ button to reduce it.
Press again the
“SET” button (but do
not hold it)

Maximum period between
regenerations in days during water
uptake idle period
Automatic regeneration during water
uptake idle period helps maintaining
microbiological cleanliness of the

period the medium may become
inhabited by microorganisms and
bacteria). With factory settings the
(
AUTO ) function will be inactive which
means that the device will not
