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 meas-
uring equipment (see chapter “Accesso-
ries”). If the raw water hardness fluctuates,
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 a
nd
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. 9).
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 opposite to „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.
