The utilised temperature safety switch (>85 °C) is combined with the
NTC sensor. If a fault occurs, the heater is switched off at a water
temperature of 85 °C (operates in switching mode).

The regeneration valve and the drainage valve are situated in the
water softening system.
If the regeneration valve is actuated, the
water stored in the regeneration chamber is conveyed through the
water softening system. If the drainage valve is actuated, the water
stored in the heat exchanger (HE) is conveyed into the rinsing tank via
the water softening system.
