INFORMATION
The maximum heat pump temperature depends on the ambient temperature. For
more information, see the operation range.
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.

WD curve type
There are 2 methods to define the weather-dependent curves:
▪
2-points
164])
▪
Slope-Offset
In [2.E]
WD curve type
, you can choose which method you want to use.
In [5.E]
WD curve type
, the chosen method is shown read-only (same value as in
[2.E]).
