5.1.3 Recalibration of residual
hardness
Due to the difference in the composition of
tap water, the set residual hardness often
cannot be reached. In this case, the regula-
tion of residual hardness can be adapted to
suit the water quality.
For example, if you have set a residual hard-
ness of 6 °e, but the residual hardness actu-
ally measured 8 °e, the adjustment can be
carried out as follows:
Press key <6> (for desired residual hard-
ness) and shortly afterwards key <8>
(measured residual hardness). The display
shows:
From this information, the control unit deter-
mines the required correction value. The
correction value is shown on the display:
After 5 seconds, the operating mode display
comes up.
The correction can be reset (see chapter
„Resetting to factory setting “).
