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 measur-
ing equipment (see chapter “Accessories”).
If the raw water hardness fluctuates, set the
higher value. Regeneration is always per-
formed with the same quantity of brine. If the
raw water hardness is high a smaller quanti-
ty of water is treated. If the raw water hard-
ness is low a larger quantity of water is treat-
ed.
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 units digit of the raw water hardness is
set using the
DIP switch
(
21
), contacts 1 to 4
(see Fig. 10).
To make an adjustment the allocated
contact of the DIP switch is moved to the
position opposite to „ON“.
For raw water hardnesses less than 10 °e,
all the DIP switch’s (20) contacts must be
set in the „ON“ position.
Contact 5 of the DIP switch (21) is moved to
the position „ON“.
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 moved to the position
opposite to „ON“.
Example: (raw water hardness 26 °e)
– Push contact 2 of the DIP switch (20)
and contact 3 of the DIP switch (21) into
the position opposite to „ON“ (see Fig.
9).
– In this case the sum of the tens digit and
the units digit is 20 °e + 6 °e = 26 °e.
