2.3 Functional description

The fresh water units enable the hygienic and energy-saving preparation of hot domestic water via a stainless steel plate heat exchanger. The energy
is supplied by a tank with a variable temperature from 60 to 95°C. At very high tank temperatures (up to 95°C) we recommend reducing the temperature
of the heating medium by mixing. The primary pump P1 is controlled with the PWM signal so that the desired hot water temperature is kept as constant
as possible. The required pump output is calculated by the controller using the primary side heating medium temperature, the hot water temperature and
the circulation, together with the current flow.
