3. P regulation with fixed setting
Ref
As "1", but an increasing deviation from the reference must be
accepted as the controller uses the difference between the actual
condenser temperature and the set reference for indicating the
number of fans that has to be cut in.
4. P regulation with floating reference
Ref
As "2", but an increasing deviation from the reference must be
accepted as the controller uses the difference between the actual
condenser temperature and the actual outdoor temperature
for indicating the number of fans that has to be cut in. (The first
3 K are left out, as there must be a possibility of cooling via the
condenser).

The number of fan steps is divided up based on the Xp value.
Recommended setting for Xp is the ∆T of the condenser, typically
10 to 15 K.
The cutin and cutout of fans are shown in the drawing.
If the entire condenser capacity is controlled by speed regulation,
the capacity will be indicated on the broken line.
