7. FAST COMMISSIONING
Once having confi gured the condensing unit, the MPXPRO/Ultracella
controllers installed on the evaporators need to be confi gured, and then
the entire system comprising the combination of both.
The fast commissioning function is an automatic procedure to assist
installers in the fi nal confi guration of the entire system: condensing
unit connected via serial line to a maximum of fi ve MPXPRO/Ultracella
controllers, as described in par. 7.4.
7.1 MPXPRO confi guration (SW version ≥ 4.0)
General connection diagram
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 manual +0300055EN rel. 1.4 of 16/02/2015.
Caution: in order to confi gure the entire system, fi rst check that the
cabinets are equipped with MPXPRO controllers and the EEV electronic
expansion valve.
