7. FAST COMMISSIONING
Once the condensing unit has been confi gured, the MPXPRO/UltraCella
controllers installed on the evaporators then need to be confi gured, and
subsequently the entire system representing the combination of both.
The Fast Commissioning function is an automatic procedure that assists
the installer in the fi nal confi guration of the entire system: condensing
unit connected via serial with up to fi ve MPXPRO/UltraCella controllers,
as described in par. 7.4.

It is recommended to follow the general connection diagram shown
here, so as to simplify the subsequent controller confi guration stage by
exploiting many of the pre-defi ned parameters.

Once the wiring has been completed, simply follow the wizard that is
displayed when the MPXPRO devices are switched on for the fi rst time.
Details of this procedure are shown below; for further information see the
MPXPRO +0300055EN rel. 1.4 of 16/02/2015..
Important: in order to confi gure the entire system, fi rst check that
the cabinets are equipped with MPXPRO controllers and the
corresponding EEV electronic expansion valve module.
