(4) To interlock to a LOSSNAY or OA processing unit, make the following settings using the remote
controller. (For a description of how to set an interlock, see section
Set the LOSSNAY or OA processing unit address and the address of all the indoor units you want
to interlock.
(5) Total length of remote controller wiring
• The simple MA controller can be wired up to 200 m (656 ft).
Remote controllers cannot be wired together. Only one wire
CAUTION
can be connected to the remote controller terminal block.
NOTE: When interlocking the MA remote controller with a LOSSNAY or OA processing unit,
always set the address of all the indoor units in the group and the address of the
LOSSNAY or OA processing unit.
2. Connecting to Mr. SLIM air conditioner
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.)

(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 Simple MA Remote Controller can control up to 16 refrigerant systems as one group.
