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 selector can be used
to set the temperature to any value from
30 °C to 55 °C. The set temperature is dis-
played using a seven-segment 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.
