• 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 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/water leaks 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.

■Securely attach the electrical component cover to the Interface unit.

If the electrical component cover of the Interface unit is not securely attached, dust or water penetration could occur,

resulting in a fire or electric shock.

3. Connecting the MA & CONTACT Terminal Interface to Indoor Unit

•Connect the interface unit and the indoor control board using the connecting cable that came with the interface.

•Extending or shortening the connecting cable that comes out of the interface may cause it to malfunction. Also, keep the

connecting cable as far as possible away from the electrical wires and ground wire. Do not bundle them together.

M series

Connect the connecting cable that comes with the

interface unit to the connector CN105 on the indoor

control board.

•When this interface unit is connected with Indoor Unit, timer operation cannot be set from a wireless remote controller.

•When this interface unit is connected with Indoor Unit, i-see sensor control cannot be used. Normal cooling or heating opera-

tion is performed. (MSZ-FA Series only)

Connect the connecting cable that comes with the

interface unit to the connector CN92/CN105 on the

indoor control board.

4. Connecting the MA & CONTACT Terminal Interface with each system

(For details on each system, see the relevant instruction manual.)

•Replace the interface unit 1 mounting cord clamp with a supplied mounting cord clamp 5–7 based on the thickness of the

connecting cable used for each system.

•The cables connected to the Indoor Unit should be mounted on or near the Indoor Unit.

If the connecting cable is not securely mounted, the connector may detach, break, or malfunction.

•Set the interface dip switch (SW500–502) settings before turning on the power.

•If the interface dip switch (SW500–502) settings are not set correctly, the system will not function properly.

4.2. Use as a Wired Remote Controller (Using the MA Remote Controller)

Note:

1. Be sure to set the “Auto Heating/Cooling Display Setting” of the MA remote controller OFF before use. When the

setting is turned ON, the remote controller display may differ from the actual operating status of the unit.

• For details on the “Auto Heating/Cooling Display Setting,” refer to the MA remote controller instruction manual.

2. A test run cannot be initiated using the test run switch on the MA remote controller.

3. The horizontal vanes on the unit cannot be operated using the louver switch.

4. The range of room temperature indication is between 10°C and 38°C.

Only turn this ON when the indoor units in the same group include models where the MA remote controller and

indoor unit are directly connected.

Set them to ON only when using the room temperature sensor installed in the MA remote controller.

* This can be switched when an accurate room temperature cannot be detected by the air conditioner unit.

MSZ-GA and MSZ-FA Series models can not use a room temperature sensor on their MA remote controllers.

(Some M series models will not allow the use of the MA remote controller room temperature sensor.)

No. 5 and 6 should normally be set to OFF.

Under the following conditions, however, they should be switched to ON.
