6.2 Condensation
Condensation adjustment depends on how the fans are turned on.
Various condensation adjustment types in the “chiller” operating mode are shown below.
The fans may be turned on using the on/off system ( “step”) in which the fans are turned on
progressively one after the other (figure 6.3a) or mutually excluded (figure 6.3b). Fans switched on in
parallel but that increase fan speed (depending on pressure) are illustrated in figure 6.3c).
