6.2 Definition of terms

Hysteresis Band around pressure setting in bar.
The upper limit is calculated from the
pressure setting+(hysteresis/2)
pre-set in the factory to 0.2 bar
Pressure setting The system's pressure setting is pre-set at the
factory at 2 bar
Time Time in which the system has to reach the top
pressure value during backfeed,
pre-set at the factory at 15 min
Cycle Number of measurements per hour,
pre-set at the factory at 2
Water Total water consumption of the system. Serves
to detect system leakages
Overflow Top limit of measurable water consumption
Switch-off quantity Automatic switch-off after a set quantity of water
flows through
This function is necessary when using softening
cartridges
Remaining capacity Display of the remaining capacity when using
softening cartridges
