In this mode, you enter the refrigerant used in your plant. Additional-
ly, it is possible to select the units of pressure, temperature and EIV.
You can also configure the types of sensors according to your spe-
cific application.
An incorrect entry for the refrigerant can damage your plant!
Optionally, it is possible to configure the control of the cooling capac-
ity (refer to chapter 6). The controller by default comes with capacity
control deactivated.
