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 "10.4 Weather-dependent
curve"[4146].
