Setting Time
In order to set time, press
▲
button to move
ahead or
▼ button to set time back.
If a twelve-hour clock is set, the “ante
meridiem” (“AM”) caption will appear on
the display screen for the after midnight
part of the clock - hours between 0
00
and
11
59
and the "post meridiem” (“PM”) caption
for the after midday part of the clock - hour
between 12
00
and 23
59
.
With each pressing of one of the
▲
or
▼buttons the time will increase or decrease
with one minute increments. If any of the
buttons remains pressed the time will change
at a faster rate.
Programming water hardness
Single press of the SET button (in Set Time
mode) will move programming to the SET
HARDNESS mode (Water hardness); the
value flashing on the display screen should be
25 (default value).
Now code the hardness of used water in
grains per American gallon - gpg (water
hardness expressed in, for example,
o
dH - in
accordance with the German scale, should be
multiplied by 1.036). Water hardness can be
expressed in different units. Below is the table
showing water hardness units most commonly
used in the 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
obtained 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. The adjusted water
hardness is calculated with the
following formula:
Adjusted water hardness [
o
f] = water hardness [
o
f] + 4.8

iron content in Fe mg/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
▲
or
▼ button until
the relevant number appears on
the display screen. Pressing the
▼ button will reduce the displayed
