Function
The controller has a setting where you can choose between various
types of installation. If you use these settings, the controller will sug-
gest a series of connection points for the different functions. These
points are shown below. (The options shown are determined by
previous settings in the menu, e.g. cooling agent and "Pack type".)
Even if your installation is not 100% as described below, you can still
use the function. After use, you need only adjust the divergent set-
tings.
The given connection points in the controller can be changed if you
wish.
