Function

The product heats up drinking water via a bare wire in the
heating block using the flow-through principle.
The drinking water can be drawn from several draw-off
points.
The electronics measure the temperature of the water in the
cold water supply and the water volume flow. The electrical
performance that is required to heat the water to the required
hot water temperature is calculated using these two values.
The temperature can be set to any value between 30 °C and
60 °C on the product's temperature selector.
The hot water temperature depends on:
–
Water inlet temperature
–
Water outlet volume
–
Performance category of the unit
If the set hot water temperature is not reached, reduce the
water volume.
