2. Connecting to M-series and P-series air conditioners
The remote controller wiring depends on the system configuration. Check the system configuration.
Wire the remote controller as shown in the example below.
The numbers (1) to (3) in the figure correspond to items (1) to (3) in the following description.

* Set the refrigerant address using the outdoor unit dip switches. (For more information, refer to the
outdoor unit installation manual.)
* All the indoor units enclosed in
(1) Wiring from remote controller
• Connect to indoor unit TB5 (remote controller terminal block). (The terminal block has no polarity.)
• For simultaneous multi type, when mixing various types of indoor units, always connect the
remote controller to the indoor unit with the most functions (wind velocity, vane, louver, etc.).
(2) When grouping with difference refrigerant systems
• Group using the remote controller wiring. Connect the remote controller to an arbitrary indoor unit
of each refrigerant system you want to group.
• When mixing different types of indoor units in the same group, always make the outdoor unit
connecting the indoor unit with the most functions (wind velocity, vane, louver, etc.) the Main unit
(refrigerant address = 00). Also, when the Main unit is the simultaneous multi type, always satisfy
the conditions of (1) above.
• The MA Remote Controller can control up to 16 refrigerant systems as one group.
(3) Up to two remote controllers can be connected to one group
• When only one remote controller is connected to one group, set it as the Main controller. When
two remote controllers are connected to one group, set the Main remote controller and Sub
remote controller. (For a description of how to set the Main/Sub setting, refer to the section on
initial setting in this manual.
