Connecting the SYSTEM CONTROL Interface to MA remote controller
A room air conditioner can be operated with the wired remote control.
● To connect with the MA remote controller, connect the MA remote control cable with TB580. (It is unpolarized.)
● When more than one unit of room air conditioner is operated in a group, make a cross wire connection at TB580 with the MA
remote control cable .
● The MA remote controller can carry out simultaneous control of up to 16 sets of room air conditioners.
● Up to two MA remote controllers can be connected in one group.
However, up to one can be connected when using PAR-CT0 MA.
● Wiring length from the interface at the refrigerant address “0” to the MA remote controller should be less than 10 m [33 ft.].
● To operate the room air conditioner in a group, make the total length of wiring for the MA remote controller less than 50 m [164 ft.].

on the MA remote controller.
• Group control with CITY MULTI is unable.
Notes
• Set a different refrigerant address for each
room air conditioner even when a MULTI
