Programming water hardness
Single press of the “OK” button (in the Time
mode) will cause the transition to the
HARDNESS mode; the value flashing on the
display screen should be 25 (default value).
Then, it is necessary to code the hardness of
used water in grains per American gallon -
gpg (water hardness expressed in, for
example, the German
o
n should be multiplied
by 1.036). The water hardness can be
expressed in different units. Below is the table
showing water hardness units most commonly
used in our country:

In case when the results of the
physical and chemical analysis
are not available, water hardness
information should be obtained
from local water supply company
or from relevant regional office of
the State Sanitary Inspectorate or
it should be self determined with
the use of a test which can be
ordered from the vendor. Please
enter the results obtained on page
4 of this manual as well as on a
separate label, which should be
placed under the brine tank cover
with the use of adhesive tape.
If raw water contains iron in
concentration exceeding 0.2 mg/l,
please use adjusted water
hardness instead of water
hardness. It is calculated in the
following manner:
Adjusted hardness [
o
dH] = hardness [
o
dH] + 4.8
iron
quantity in mg Fe/l
Enter the water hardness number
or adjusted water hardness
number (expressed in gpg) to the
water softener software as
operational water hardness. In
order to enter the water hardness
number press and hold
▲
or ▼
until the relevant number appears
on the display screen. Pressing ▼
will reduce the displayed water
hardness value to 1. Pressing
▲
will increase the displayed water
hardness value to the maximum
value for the given device.
Between water hardness values of
1 and 25, each pressing of
▲
or
▼ will respectively increase or
reduce the water hardness value
in one unit increments. The value
increases or decreases by 5 units
in the range between 25 and the
maximum value. If the button
remains pressed, the value will
change twice in one second.
Programming regeneration hour
Single press of the “OK”
button (in Hardness mode) will
cause the transition to the
RECHARGE TIME mode; the
value flashing on the display
screen should be 02:00 (2 a.m.)
as default value.
If this setting is confirmed (by
pressing the “OK” button), the
water softener will activate the
regeneration process at 2 a.m.
Due to water consumption
reduced to minimum at night, 2:00
a.m. is the optimum regeneration
hour.
In order to change the
regeneration hour settings, press
