3.2 Function
The product heats up potable water via a
bare wire in the heating block using the
flow-through principle.
The electronics measure the temperature
of the water in the cold water supply and
the water volume flow. The electrical per-
formance that is required to heat the water
to the required domestic hot water temper-
ature is calculated using these two values.
The temperature can be set to any tem-
perature between 20 °C and 55 °C in in-
crements of 0.5 °C. The set temperature is
shown in the display.
The domestic hot water temperature de-
pends on:
–
Water inlet temperature
–
Water outlet volume
–
Performance category of the product
If the set domestic hot water temperature
is not reached, reduce the water volume.
