6.5.3 Changing the correction value for the flow temperature

The control calculates the target flow temperature in heating mode in accordance with the external temperature and the heating
characteristic that has been set. In the storage loading operation and the special functions "manual warm water boost charge"
as well as "manual operation" constant target flow temperatures are used. If the desired room temperature is not reached despite
the correct heating characteristic being set, the operator can adjust the flow temperature by entering a correction value. The
correction causes the heating characteristic to undergo a parallel shift in accordance with the set value.
