4.1.1 Regeneration electronics
The electronics determine, in comparison with the water hardness set
on the appliance, the volume of water which is possible until the
softening system is exhausted.
The number of rinse cycles is counted. Regeneration then takes place
once the maximum possible number of rinse cycles has been
reached.
The sequence characteristics of the regeneration electronics are des-
cribed under Initial start-up / Replacing the electronics.
4.1.2 Warm water detection
If the water running into the final rinse cycle is hotter than 45 °C, the
temperature in the final rinse cycle is increased to 72 °C in order to
increase the inherent heat of the dishes. The heat exchanger is not
filled.
4.1.3 Power failure
The electronics module has a power failure memory function which
ensures that the current rinse programme continues in the event of
a power failure or programme interruption.
4.1.4 Sensors
All outgoing signals from the door switch, the level switch, the NTC
sensor and the refill switches are recorded and evaluated by the
microprocessor at the required time.
