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
"10.5 Weather-dependent
curve" [ 4 158].

Note: There are 2 methods to set the weather
dependent curve. See "10.5.2 2-points
curve" [

159] and "10.5.3 Slope-offset
curve" [
4
160] for more information about the
different curve types. Both curve types require 4
field settings to be configured according to the
figure below.

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