5.1.1 Setting the raw water hardness
The value depends on the place of installa-
tion. You can ask the responsible water-
works or determine it using suitable
measuring equipment (see chapter “Acces-
sories”). If the raw water hardness fluctu-
ates, set the higher value. Regeneration is
always performed with the same quantity of
brine. If the raw water hardness is high a
smaller quantity of water is treated. If the
raw water hardness is low a larger quantity
of water is treated.
The raw water hardness is set using the
DIP switches (20 and 21).
The tens digit of the raw water hardness is
set using the DIP switch (20), contacts 1 to
8.
The unit digit of the raw water hardness is
set using the DIP switch (21), contacts 1 to
4 (see Fig. 11).
The allocated contact is moved downwards
to make an adjustment.
Example: (raw water hardness 26 °e)
Push contact 2 of the DIP switch (20) and
contact 3 of the DIP switch (21) downwards
(see Fig. 11).
In this case the sum of the tens digit and the
unit digit is 20 °e + 6 °e = 26 °e.
For raw water hardnesses less than 10 °e,
all the DIP switch’s (20) contacts must be
set at the top in the "
OPEN
" position.
Contact 5 of the DIP switch (21) is pushed
downwards.
The controls react to incorrect settings with
an acoustic signal (see “Faults” chapter).
The country to be set is adjusted using
the DIP switch (21), contacts 6 to 8. To
set the English hardness the contact 8 of
the DIP switch (21) is pushed down-
wards.
