5.1.6 Descale management
It is important to know the correct hardness of the water at the location where the Bolero is
used (for setting the descaling signal).
If necessary, ask the local water company for the hardness of the water supplied or measure
the hardness of the water supplied on site with a water hardness tester (according to the
corresponding instructions).
Default: ON (with average water hardness)
