CONTROLLING THE REGENERATION
Regeneration is automatically carried out via wear-free ceramic disc valves. The regeneration procedure
is precisely defined by the disc geometry, which ensures that the procedure does not have to be re-started
after power failure.
6.5.5
OVERFLOW VALVE
If the withdrawal of a very large amount of water (e.g. flushing valve) results in a loss of pressure in the wa-
ter softening system in excess of 1.0 bar, an overflow valve integrated in the control head opens up to per-
mit untreated water to pass by the water softener, thus limiting the loss of pressure. In this process, the
mixed water hardness will temporarily increase in the downstream softener line.
