In: Type of unit
This parameter In assigns the function of Master or Slave to the controller.
Hecu CO2 only accepts MPXPRO master controllers, therefore this
parameter must always be set to “1”.
Par. Description Def Min Max UOM
In Type of unit: 0 = Slave; 1 = Master 0 0 1 -
Tab. 7.a
Sn: Number of slaves in the local network
This parameter tells the Master controller how many Slave controllers it
needs to manage in the local network. Hecu CO2 only accepts MPXPRO
master controllers, therefore this parameter must always be set to “0”.
Par. Description Def Min Max UOM
Sn Number of slaves in the local network
0 = no Slaves 0 0 5 -

H0: Serial or Master Slave network address
Parameter H0 indicates the MPXPRO serial address.
Par. Description Def Min Max UOM

Once the wiring has been completed, simply follow the wizard that is
displayed when the Ultracella devices are switched on for the fi rst time.
Details of this procedure are shown below; for further information see the
UltraCella 0300083EN.
Important: in order to confi gure the entire system, fi rst check that
the cold rooms are equipped with UltraCella controllers and the
corresponding EEV electronic expansion valve module.
