To connect with the MA remote controller, connect the MA remote control cable C 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 C .
The MA remote controller can carry out simultaneous control of up to 16 sets of room air conditioners.
Up to two MA controllers can be connected in one group.
Wiring length from the interface at the refrigerant address "0" to the MA remote
controller should be less than 10m [33ft.].
To operate the room air conditioner in a group, make the total length of wiring for the MA
remote controller less than 50m [164ft.].
Notes
• Be sure to set the "Auto Heating/Cooling Display Setting" of the MA
remote controller OFF before use.
* For details on the "Auto Heating/Cooling Display Setting", refer to the
MA remote controller instruction manual.
* When the "Auto Heating/Cooling Display Setting" is ON, the remote
controller display may differ from the actual operating status of the unit.
• A test run cannot be initiated using the test run switch on the MA
remote controller.
