● To connect with the MA remote controller, connect the MA remote control cable
● 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.].
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.
• Group control with CITY MULTI is unable.
• When you use the PAR-CT0 MA with M-NET system, follow the
restrictions below.
1. Be sure to set "Brightness setting" of PAR-CT0 MA to "Low".
2. The wiring length from the interface at the refrigerant address "0" to the
PAR-CT0 MA should be less than 7 m [23 ft.].
3. Some room air conditioners cannot be used.
Make sure the room air conditioner can be used before installing it.
4. Do not use the external output (CN104) of the indoor unit.
* If the indoor unit does not have the external output (CN104), you
