and Check Codes generated in the past appear on the display.
For Check Codes and Symptoms refer to the table.

[Emergency operation procedure]

1.When the indoor unit microcomputer has failed, but all other components
work properly, if you set the switch(SWE,SW6)on the indoor control
board, the indoor unit will begin Emergency Operation.

2.When you activate emergency operation of the cooling you have to set
the switch(SWE)and switch(SW6)on indoor controller.

SWE:ON ·Indoor fan is running high speed.

·Drain-up machine(optional)is working.
SW6-1:ON ·Emergency operation of cooling mode.

3.Before you activate emergency operation, check the following points:
(1) Emergency operation cannot be activated when:

· The outdoor unit malfunctions. · The indoor fan malfunctions.
(2) Emergency operation becomes continuous only by switching the power
source on / off. ON / OFF on the remote control or temperature control
etc. does not function.
(3) Emergency cooling should be limited to 10 hours maximum
(The indoor unit heat exchanger may freeze).
(4) After emergency operation has been deactivated, set the switches etc.
to their original positions.
(5) Movement of the vanes does not work in emergency operation, therefore
you have to slowly set them manually to the appropriate position.

1.When the indoor unit microcomputer has failed, but all other components work properly, if you set the switch
(SWE,SW6)on the indoor control board, the indoor unit will begin Emergency Operation.

2.When you activate emergency operation of the cooling you have to set the switch(SWE)and switch(SW6)on
indoor controller.

SWE:ON ·Indoor fan is running high speed.

·Drain-up machine(optional)is working.
SW6-1:ON ·Emergency operation of cooling mode.

3.Before you activate emergency operation, check the following points:
(1) Emergency operation cannot be activated when:

· The outdoor unit malfunctions. · The indoor fan malfunctions.
(2) Emergency operation becomes continuous only by switching the power source on / off. ON / OFF on the
remote control or temperature control etc. does not function.
(3) Emergency cooling should be limited to 10 hours maximum
(The indoor unit heat exchanger may freeze).
(4) After emergency operation has been deactivated, set the switches etc. to their original positions.
(5) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them
manually to the appropriate position.

• There are two types of remote controllers: wired type
and wireless type.

• Simultaneous twin indoor units are started or stopped
simultaneously.

• Up to two remote controllers can be connected to
one group.

• Simultaneous twin units are counted as each unit.

• Operation control by the latest command (last en­tered priority)

• Wired and wireless remote controllers can be com­bined as a pair.

• One group can consist of up to 16 indoor units, and
they can be started sequentially by connecting the
remote controller to them and assigning an address
to each inter face.

• Simultaneous twin units are counted as one unit.

• All the units belonging to the same group are oper­ated in the same mode, but thermostats can be
turned ON/OFF individually for each indoor unit.

• Up to two remote controllers can be connected.

• All the air conditioners can be turned ON/OFF collectively
from a distance.

• Operation can be switched between the remote operat­ing panel and local controller.

• Operations (e.g., temperature adjustment, airflow, air­flow direction) except for start/stop operations can be
performed even if the remote controller is being oper­ated.

• In the case of simultaneous twin units connect the

controller to one indoor unit only. If connected to two
indoor units, an error (operation stop) may occur.

• Control by an external timer is possible by connecting it.

• Use of optional "remote ON/OFF adapter" enables
remote control via relay. (Level signal)

• Whenever a power outage or switching of the power supply causes the power supply of an operating air conditioner to go
from OFF to ON, this function will automatically restore the operation of the air conditioner to its previous operating mode.
w If the power is turned from OFF to ON when the air conditioner is not in operation, the air conditioner will not automatically

be turned on. However, the timer operation will be cancelled if the air conditioner is in timer operation (including when the
unit is waiting for its start time). Setting for timer operation must be performed once again.

• If there is a momentary power outage of less than one second while the air conditioner is in operation, there may not be a
clear determination of whether or not there was a power failure. When it has been determined that there has been a power
failure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" has
appeared on the display, a protection system will operate to prevent the unit from restarting for three minutes.)

When it has been determined that there has been no power failure, operation will continue as is.

• Settings can be made by function selections from the remote controller.

• When there is group control, selection of all refrigerants is required.

9-6. INDIVIDUAL CONTROL OPERATION FROM A SEPARATE ROOM

• By simply centralizing the remote controllers installed in each room in a separate control room, individual control or central­ized monitoring of the air conditioners in each room can be attained.

• Air conditioner control can be performed up to a total of 500 meters away by connecting the indoor units and remote con­trollers with 0.3 to 1.25 mm22-core cable.

• If a remote controller is installed in a room and control room, refer to the section on operating with two remote controllers.

9-7. COMBINED REMOTE/LOCAL CONTROL

• Operation/remote controller prohibit/ stop can be controlled from a remote location by routing the remote stop/start adapter
(PAC-SE55RA-E sold separately) through the relay box installed on site. When this remote control is cancelled, the local
remote controller can be used for operating and stopping the air conditioner.

1. Basic system wiring

• Use the remote start/stop adapter (PAC-SE55RA-E) and connect the "Start/Stop Circuit From Remote Location" that comes
from the relay box and remote/local selection switch and connect it to the CN32 connector on the printed circuit board for
the indoor unit

<Points of precaution>

1 Match the rated power supply voltage of the remote/local selection switch and relay (X2) with the power supply for the con-

troller.

2 When performing group control of multiple outdoor unit using a timer, be sure to arrange the timer so that all units do not start

at the same time. If this is not performed, all of the units will start at one time creating an over current that will cause the circuit
breaker to operate.

3 An on-delay system is one that includes specifications for operating a limited time when an on signal is received and has a tem-

porary off timer for recovery operations.

4 Use a connecting relay when the wiring length exceeds 10 meters, such as when performing remote wiring. If this is not pro-

vided, abnormal operation will occur.

9-9. TIMER OPERATION

● Timer operation can be performed by setting the wired or wireless remote controller timer. Start and stop times can be set in
10-minute increments within a 24-hour period.

● When used in combination with the central control remote controller of the M-NET control system for the outdoor unit, one
program timer can be used for individual timer settings for each group of the central control system. (Each timer setting can
be stored in data memory so timer settings for up to 50 groups can be set individually.)

W Please refer to the MELANS catalog or technical information for details about the central control remote controller.

9-10. LINKED OPERATION WITH PERIPHERAL AIR CONDITIONERS EQUIPMENT

■ Lossnay operation

● Linked operation with a Lossnay unit can be obtained by connecting Lossnay linkage cable (Model PAC-SB81VS - sold

separately) to the CN2L (Remote kit) on the circuit board of the indoor unit. This function must be selected from the
remote controller.

1 Summary of wiring

● Connect the Lossnay linkage cable (Model PAC­SB81VS) connector to CN2L on the indoor unit on the
circuit board of the indoor unit.

● Connect the lead wire of the Lossnay linkage cable to
the Lossnay external control input terminal blocks (1)
and (2).
(At this time, the input terminal blocks (1) and (2)
have no polarity.)

2 Precautions when wiring

● The Lossnay linkage cable can be extended up to a maximum of 500 meters.
When extending the Lossnay linkage cable, be sure to connect securely and take proper steps to ensure insulation.
(Extension cable specifications: Sheathed vinyl cord or cable 0.5 to 0.75mm

● Lossnay linked cable

● Arrange wiring so that there can be no contact between the Lossnay linkage cable and the power supply cord. Contact

may cause malfunctioning. (Separate by 5cm or more.)

)

9-11. OBTAINING HUMIDIFIER SIGNAL

● The humidifier signal that is linked to the AC heating operation (indoor unit ventilator) can be obtained by connecting the
adapter for the humidifier signal to connector CN25 on the printed circuit for the indoor unit and wiring it to the humidifier
unit via the on-site relay box. There is no output when the thermostat is off, during heating preparation and during
defrosting.

W Please consult your nearest Mitsubishi Electric

representative for information about obtaining the
adapter for humidifier signal.

9-12. EXTERNAL MOUNTING OF TEMPERATURE SENSOR

● Temperature control from an alternative external location can be performed by connecting the temperature sensor (Model
PAC-SE41TS-E - sold separately) to the CN20 connector on the circuit board for the indoor unit.

● The wired remote controller also has an internal temperature sensor. Function selection from the remote controller is
required.
Refer to “FUNCTION SETTING” for information of installation manual about selecting functions with the remote controller.

Note 1. How to connect refrigerant pipes.

Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures. As long as con­nection takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the indoor and outdoor
units are made, open the stop valve on the outdoor unit to allow refrigerant gas to flow.
If piping length exceeds 20m, an additional charge of refrigerant in needed.

Note 2. The following main parts are contained in the optional refrigerant piping kit.

Heat insulating cover, vinyl tapes, nipples, sleeve and flange (for wall hole).
