INFORMATION
The maximum heat pump temperature depends on the ambient temperature. For
more information, see the operation range.
WD curve type
There are 2 methods to define the weather-dependent curves:
▪ 2-points (see "10.4.2 2-points curve" [
4
146])
▪ Slope-Offset (see "10.4.3 Slope-offset curve" [
4
147])
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]).
