WD curve type
The weather dependent curve can be set using the 2-points method or the
Slope-Offset method. For more information about each method, see "10.4.22-
points curve"[4142] and "10.4.3Slope-offset curve"[4143]. The curve type in the
menu is read only, and will correspond to the curve type set for the main zone.
Changing the curve type for the additional zone must be done in the main zone WD
curve type [2.E] menu. See "10.5.3Main zone"[4150] for more information.

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 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 "10.4.2 2-points curve" [4 142] and
"10.4.3Slope-offset curve"[4143].
