If it's P-series, you'll require a terminal block and CN22 connector + controller for each split.
If it's M-series, you'll require a Interface MAC-3971F + controller for each split.

Re: mitsubishi electric
If the units are Mr Slim type & you want to group control both units from one PAR21MAA remote controller then you will need to set the refrigerant address of the two outdoor units & daisy chain the 2 core control cable from the remote controller to both indoor units using the remote controller 12v dc connections.
If both outdoor units are left with factory setting stand alone refrigerant address 00 then the systems will not work & will report a comms error like EA fault code.
The details of address setting dip switch is normally on the lable inside the outdoor unit cover.

MSZ = M-Series - Indoor will require a MAC-3971F + controller.
