Main fan OFF/ON OFF
Allows to test the operation of the components when the unit is OFF. Basic securities
are still active in this mode. To start the compressors, it is recommended to start the
main fan before. When the compressor(s) are started, the EEV (when equipped) are
automatically managed except if manually driven (see analog outputs).
