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
