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
RAW WATER MONITORING
A sensor in the supply side of the water softener continuously monitors the raw water intake. This way, the
system knows the amount of water which will start a regeneration.
6.5.6
AUTOMATIC RESIDUAL HARDNESS REGULATION
Depending on the raw water quality and desired residual hardness, the internal blending unit is automati-
cally adjusted by means of a servo motor.
6.5.7
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, resid-
ual hardness will temporarily increase in the downstream softener line.
