Operation
and after 3 seconds:
After 3 seconds the permissible minimum
value of the desired water hardness is dis-
played. This may be followed by the mes-
sage:
The following is shown after 3 seconds:
After pressing the <OK> key the desired wa-
ter hardness minimum value is memorized
as the new setpoint value. By pressing the
keys
and
, the desired water hardness
can be set and forced with the <OK> key
even if the sodium value is exceeded.
5.4.5 Desired water hardness
recalibration
Due to the different composition of the de-
sired water, the desired water hardness may
not be reached. In this case, the desired wa-
ter hardness can be adapted to the water
quality.
If, for example, the water hardness is set at
8 °e, but the residual hardness measured is
10 °e, the water hardness can be adapted
as follows:
Press the
key 1x and then
2x. The
display shows the following:
Press key <OK> 1x and then key
as often
as necessary, until the display indicates the
following:
Press the <OK> key. The display shows the
following:
Use the
key to reduce the measured re-
sidual hardness value and the
key to in-
crease it. The step size is 1 °e.
The chosen residual hardness setting is
saved by pressing <OK>.
On the basis of these values the control unit
generates the necessary correction value.
The recalibration of the residual hardness is
reset as soon as the customer settings are
reset to the factory settings (see
chapter 5.15 “Resetting to factory setting”).
If the sodium content is exceeded, a
“2” is displayed at the end of the first
line of the display.
