Setting of the water hardness
ATTENTION
In order to guarantee the optimum function-
ality of the descaler cartridge, the device
must be set to the local water hardness pri-
or to the first operation.
This is done via the RESET button.
Notes
 The device is set to the highest water
hardness level (level IV) by default.
 After completion of the water hardness
setting, it remains saved until a new set-
ting (e.g. after relocation) is necessary.
 During the setting no pause of more
than 15 seconds may take place. Other-
wise the device is automatically set to
the water hardness selected last or the
highest water hardness with initial start-
up.
Please observe the following procedure:
 Connect the mains cable to the power
supply system.
 The device must be switched off prior to
the setting.
 Push the RESET button and hold it
down during the start-up of the device.
 After 2 seconds the indicator light is
blinking and signals the current setting
of the water hardness via the number of
impulses.
 By repeatedly pressing the RESET but-
ton, the setting of the water hardness
level changes.
 As long as the RESET button is
pressed, the flashing impulse for the
relevant water hardness level is not
shown.
 As soon as the button is released, the
flashing impulse appears for the output
of the selected water hardness.
 If the water hardness is set to the de-
sired level, hold down the RESET but-
ton for 3 seconds so that the setting is
saved.
 The saving process is displayed by the
lighting up of the indicator light for the
water hardness.
