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 only
or
Schedule + reheat
domestic hot water
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

In domestic hot water operation, the following hysteresis value can be set for the
heat pump operation:
