How many KF2 controllable springs can be connected to a single Cooler Unit?

KF2 - Cooler Unit
The maximum heat effect for all springs combined has to be lower than the cooling effect of the cooler. If a group of springs’ heat factor added up together is over the maximum heat factor for the ”NitroCoolerTM used for 1pc KF2 spring” (see page 10.4/6 ), please secure according to the diagrams on page 10.5/14.
See chapter 10 in the Main KALLER Catalog.
