8.2 Unit Type
With the machine in OFF status, using the PGUT parameter from the CONSTRUCTOR/CONFIGURATION menu, it is possible to select
the unit type to be used. Control and other parameters corresponding to the various functions must be manually modified according to
user requirements. All the default unit have 2 compressors for each circuit.
Managed machines are listed below, together with their respective input and output configurations.
