WD curve
When weather-dependent operation is active the desired tank temperature is
determined automatically depending on the averaged outdoor temperature: low
outdoor temperatures will result in higher desired tank temperatures as the cold
water tap is colder and vice versa.
In case of Schedule
preparation, the storage comfort temperature is weather-dependent (according to
the weather-dependent curve), the storage economic and reheat temperature are
NOT weather-dependent.
In case of Reheat only domestic hot water preparation, the desired tank
temperature is weather-dependent (according to the weather-dependent curve).
During weather-dependent operation, the end-user cannot adjust the desired tank
temperature on the user interface. Also see
