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.
"11.4 Weather-dependent curve"
161].
WD curve type
There are 2 methods to define the weather-dependent curves:
▪
2-points
(see
▪
Slope-Offset
(see
162])
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]).
