A control unit for a softening device, comprising a primary inlet for untreated water, a primary outlet for blended water, a sensor for determining the water hardness of the untreated water WHraw, or the blended water WHblend, a secondary outlet, a secondary inlet, a bypass line, a blending means which can be automatically adjusted for mixing a blended water flow Vblend(t) from a first partial flow (V(t)part1soft of the secondary inlet and a second partial flow V(t)part2raw of the bypass line, and an electronic control means, wherein the control means is designed to readjust the adjustment position of the blending means by means of the determined water hardness in such a fashion that the water hardness in the blended water flow Vblend(t) is adjusted to a predetermined desired value, enables partial softening of water on the basis of fully automatic blending, thereby utilizing already existing softening devices. |
