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
"11.5 Weather-dependent
curve" [ 4 167].

WD curve :
Note: There are 2 methods to set the weather
dependent curve. See "11.5.2 2-points
curve" [
4
168] and "11.5.3 Slope-offset
curve" [
4
169] for more information about the
different curve types. Both curve types require 4
field settings to be configured according to the
figure below.

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