About SYSTEM CONTROL Interface
● Some room air conditioners cannot be attached to the interface.
Please make sure the room air conditioner can be used before attempting to attach it.
1. Safety Instructions
●Read all Safety Instructions before using this device.
●This manual contains important safety information.
Be sure to comply with the instructions.
●After installing the interface, provide this Installation Manual
to the user. Instruct users to store their room air conditioner
Instruction Manual and Warranty in a safe location.
WARNING
(Improper handling may have serious consequences, including serious injury or death.)
■Users should not install the Interface on their own.
Improper installation may result in fire, electric shock, or
damage/water leaks if the Interface unit falls. Consult the
dealer from whom you purchased the unit or professional
installer.
■The Interface should be securely installed in
accordance with the enclosed Installation Instructions.
Improper installation may result in fire, electric shock, or
damage if the Interface unit falls.
■The unit should be mounted in a location that can
support its weight.
If installed in an area that cannot support the unit, the
Interface unit could fall and cause damage.
■Mount so wiring external force and stress are not
transmitted at the terminal connection.
Improper connection and mounting may result in breaking,
heat generation, smoke generation, or fire.
■Securely attach the cover to the Interface unit.
If the cover of the Interface unit is not securely attached,
dust or water penetration could occur, resulting in a fire or
electric shock.
■The Interface unit should not be connected to the AC
power cable.
Connecting greater than the rated voltage may result in
damage or fire.
■Mitsubishi components or other designated
components must be used for installation.
Improper component may result in fire, electric shock, or
damage/water leaks if the Interface unit falls.
■Electric work must be perform by authorized personnel
according to the local regulations and the instructions
detailed in the installation manual.
Inadequate circuit capacity or improper installation may result
in electric shock or fire.
■This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a
person responsible for their safety.
■Children should be supervised to ensure that they do not
play with the appliances.
■This device complies with part 15 of the FCC Rules. Operation
is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including
interference that may cause undesired operation.
■This Class B digital apparatus complies with Canadian
ICES-003.
Cet appareil numérique de la classe B est conforme à la
norme NMB-003 du Canada.

Use as wired remote controller (Fig. 2-2)
You can use the MA remote controller as a wired remote controller.
Remote control (Fig. 2-3)
You can turn on and off an air conditioner from a remote location by connecting the ON/OFF contact point.
Status indicator output (Fig. 2-4)
Operation on/off and error/ok status can be output at the same time.

● The connecting cable (5-core) connected to a room air conditioner should be wired according to the room air conditioner installation manual.
Notes
• Extending or shortening the connecting cable (5-core) that comes out of the interface unit ❶
cause it to malfunction. Also, keep the connecting cable (5-core) as far as possible away from the
electrical wires and ground wire. Do not bundle them together.
• To prevent the board from being damaged by static electricity, always remove static electricity
before starting work.

Notes
• Electrical work should be performed in accordance with the Technical Standards Regarding Electrical Equipment and the Interior Wiring Standards.
• Connecting wires and remote control cables should be located as far away from other electrical wiring as possible. Placing them too closely
together could cause a malfunction.
• To connect with the M-NET system and MA remote controller, connection is limited to only one unit of the MA remote controller.
• Do not put in the same group as City Multi or P series.
• Test run cannot be conducted from the ME remote controller or the system controller.

Notes
• Connecting terminal TB530 for power supply is polarized, so confirm proper polarity of the terminals before connecting.
• Do not connect DC12V from the DC power supply to TB571.
• Confirm polarity when using a diode built-in relay. C of TB571 is electropositive potential + , and R1 and R2 are negative potential
● For TB571 and TB530, insert wiring after inserting the flathead screwdriver into the terminal.
● Appropriate electric wire for TB571 and TB530 is as follows. Stranded wire: 0.3mm2 to 1.25mm2 Solid wire: ø0.4mm to ø1.2mm
● Peeling dimension of the electric wire for TB571 and TB530 is 7mm to 10mm.

14. Mounting the SYSTEM CONTROL Interface Unit
Notes
•The Interface unit should be placed in a location where the connecting cable (5-core) from the interface unit can reach an indoor unit.
•The device will not function properly the connecting cable is extended, so the connecting cable (5-core) should no be extended.
•Mount the interface unit securely to a pillar or wall using 2 or more screws.
Attach the connecting cable (5-core) of the interface unit ❶ here. Store extra connecting cable (5-core) in the ductwork space behind
the air conditioner.
If there is any slack in the connecting cable (5-core), use a fastener ❾ to keep it in place.

will not fall.
15. Notes Regarding Use
The following control information should be thoroughly explained and provided to the users of this device. (Please provide these instructions to the
user once the installation is complete.)
This Interface unit ❶ operates room air conditioners using the controls of a City-Multi or P series, but there are several limitations imposed as a result
of the functional differences between room air conditioners and packaged air conditioners.
1. When operating the system using a System Controller, MA Remote Controller, or ME Remote Controller these operations will not appear on the
display of the wireless remote controller.
2. When original dehumidification mode is set with the remote controller attached to the room air conditioner, “Dry” is displayed because there is no
mode corresponding to dehumidification on the MA remote controller, ME remote controller, and the system controller.
3. Because the temperature range of the room air conditioners is broader than a System Controller, ME Remote Controller, or ME Remote Controller,
when the room air conditioners is set to lower than 17°C or higher than 30°C, the temperature display on the a System Controller, MA Remote
Controller, or ME Remote Controller will show the minimum or maximum temperature that can be set. (For example, even if the room air conditioner
is set to cool a room to 16°C, the display on a System Controller, MA Remote controller, or ME Remote Controller may read “17°C”).
4. Timer operations should be set using only the remote controller that came with the room air conditioners or the a System Controller, MA Remote
Controller, or ME Remote Controller. If both are used to set the timer to the same time, the timer will not function properly.
5. When “Manual operation prohibited” (ON/OFF, setting temperature, operation mode) is set with the system controller, the corresponding operation
by the remote controller attached to the room air conditioner is not accepted, but allowed operation is reflected. A beep sounds during operation to
confirm reception.
6. A part of functions including the operation of horizontal air blow direction cannot be used from the ME remote controller, the system controller, and
the MA remote controller.
