wThe air coverage range is the value up to the position where the air speed is 0.25m/sec.When air is blown out horizontally from the unit at the Hi notch position.The coverage range should be used only as a general guideline since it varies according to the size of the room and thefurniture inside the room.

The unit of pressure has been changed to Mpa based on the international SI system.The conversion factor is : 1(Mpa)=10.2(kgf/ FF)

Abnormality in outdoor unit. Refer to outdoor unit wiring diagram.Abnormality of the signal transmission between remote controller and indoor unit.

----FFFF

No trouble generated in the past.No corresponding unit.

Fb Abnormality of indoor controller board.

[Emergency operation procedure]1.When the wired remote control or the indoor unit microcomputer has failed,but all other compornents work if you set the switch (SWE, SW6) on the indoor control board, the indoor unit will begin properly Emergency Operation. WNote on the wireless remote control: when the remote control does not function, it is possible to activate Emergency Operation by using the indoor unit emergency operation switch (SW1,SW2 of the wireless signal receiver board). However,if the indoor unit microcomputer has failed,it is nesessary to proceed with points 2 and 3 below as in the case of the wired remote controller.2.When you activate emergency operation of the cooling or heating, you have to set the switch (SWE) and switch (SW6) on the indoor controller. SWE : ON • Indoor fan is running at high speed. • Drain-up machine is working. SW6-1 : ON • Emergency operation of cooling mode. SW6-1,2 : ON • Emergency operation of heating 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. • when it has detected the malfunction of drain-up machine during self-diagnosing. (2) Emergency operation becomes continuous only by switching the power source on/off. ON/OFF on the remote control or temperature control etc,dose not function. (3) Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated, because it will start to blow cold air. (4) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (5) After emergency operation has been deactivated, set the switches etc.to their original positions. (6) 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 wired remote control or the indoor unit microcomputer has failed,but all other compornents work if you set the switch (SWE, SW6) on the indoor control board, the indoor unit will begin properly Emergency Operation. WNote on the wireless remote control: when the remote control does not function, it is possible to activate Emergency Operation by using the indoor unit emergency operation switch (SW1,SW2 of the wireless signal receiver board). However,if the indoor unit microcomputer has failed,it is nesessary to proceed with points 2 and 3 below as in the case of the wired remote controller.2.When you activate emergency operation of the cooling or heating, you have to set the switch (SWE) and switch (SW6) on the indoor controller. SWE : ON • Indoor fan is running at high speed. • Drain-up machine is working. SW6-1 : ON • Emergency operation of cooling mode. SW6-1,2 : ON • Emergency operation of heating 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. • when it has detected the malfunction of drain-up machine during self-diagnosing. (2) Emergency operation becomes continuous only by switching the power source on/off. ON/OFF on the remote control or temperature control etc,dose not function. (3) Avoid operating for a long time when the outdoor unit begins defrosting while emergency operation of the heating is activated, because it will start to blow cold air. (4) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (5) After emergency operation has been deactivated, set the switches etc.to their original positions. (6) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position.

[Operating Procedure]1 Check the setting items provided by function selection.

If settings for a mode are changed by function selection, the functions of that mode will be changed accordingly. Check all the current settings according to steps 2to 7 , fill in the "Check" column in Table 1, and then change them as necessary. For factory settings, refer to the indoor unit's installation manual.

2 Switch off the remote controller.A Hold down the FILTER B and ( mode 15 or more) TEST

buttons simultaneously for at least two seconds. FUNCTIONSELECTION will start to flash,

and then the remote controller's display content will change as shown below.

3 Set the outdoor address.C Press the [ CLOCK] buttons ( and ) to select the desired

address. The address changes from "00" to "15".

* If the unit stops after FUNCTIONSELECTION flashed for two seconds or "88" flashes in the room temperature display area for two seconds, a transmission error may have occurred.

Check to see if there are any sources of noise or interference near the transmission path.

NoteIf you have made operational mistakes during this procedure, exit function selection (see step 0 ), and then restart from step 2 .

4 Set the indoor unit number.

D Press the ON/OFF button so that "- -" flashes in the unit number displayarea.

C Press the [ CLOCK] buttons ( and ) to select the unit numberof the indoor unit for which you want to perform function selection. The unitnumber changes to "00", "01", "02","03",04" and "AL" each time a button ispressed.

* To set modes 01 to 06 or 15 to 22 select unit number "00".* To set modes 07 to 14 or 23 to 28 carry out as follows:

• To set each indoor unit individually, select "01" to "04".• To set all the indoor units collectively, select "AL".

5 Confirm the address and unit number.E Press the MODE button to confirm the address and unit

number.After a while, "- - " will start to flash in the mode number display area.

E When the address and unit number are confirmed by pressing the

MODE button, the corresponding indoor unit will start fan operation. This

helps you find the location of the indoor unit for which you want to perform functionselection. However, if "00" or "AL" is selected as the unit number, all the indoorunits corresponding to the specified address will start fan operation.

* "88" will flash in the room temperature display area if the selected address does not exist in the system.Furthermore, if "F" appears and flashes in the unit number display area and theaddress display area also flashes, there are no units that correspond to theselected unit number. In this case, the address and unit number may be incorrect,so repeat steps 2 and 3 to set the correct ones.

* When grouping different systems, if an indoor unit other than theone to which the address has been set performs fan operation,there may be another address that is the same as the specified one.In this case, check the DIP switch of the outdoor unit to see whether such a address exists.

6 Select the mode number.

F Press the [ TEMP] buttons ( and ) to set the desired modenumber.(Only the selectable mode numbers can be selected.)

7 Select the setting content for the selected mode.

G Press the MENU button. The currently selected setting number willflash, so check the currently set content.

F Press the [ TEMP] buttons ( and ) to select the desired setting

number.

8 Register the settings you have made in steps 3 to 7 .

E Press the MODE button. The mode number and setting number will startto flash and registration starts.

The mode number and setting number will stop flashing and remain lit, indicating theend of registration.

* If " - - - " is displayed for both the mode number and setting number and " " flashes in the room temperature display area, a transmission error may have occurred.Check to see if there are any sources of noise or interference near the transmission path.

9 If you wish to continue to select other functions, repeat steps 3 to 8 .

0 Complete function selection.

A Hold down the FILTER TEST buttons simultaneously for at least two seconds.After a while, the function selection screen will disappear and the air condi-tioner OFF screen will reappear.

* Do not operate the remote controller for at least 30 seconds after completingfunction selection. (No operations will be accepted even if they are made.)

NoteIf a function of an indoor unit is changed by function selection after installation is complete, make sure that a " " mark, etc., is given in the "Check" column of Table1 to indicate the change.

E.Operation byexternal signal

F.Control and remotedisplay by externalsignal (extractionof monitor signal)

Enables you todisplay the op-eration state andcontrol start/stopfrom a distance.

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

• Simultaneous twin indoor units are started or stoppedsimultaneously.

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

• Simultaneous twin units are counted as each unit.• Operation control by the latest command (last en-

tered priority)• Wired and wireless remote controllers can be com-

bined as a pair.

• One group can consist of up to 16 indoor units, andthey can be started sequentially by connecting theremote controller to them and assigning an addressto each inter face.

• Simultaneous twin units are counted as one unit.• All the units belonging to the same group are oper-

ated in the same mode, but thermostats can beturned ON/OFF individually for each indoor unit.

• Up to two remote controllers can be connected.

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

• Operation can be switched between the remote operat-ing panel and handheld controller.

• Operations (e.g., temperature adjustment, airflow, air-flow direction) except for start/stop operations can beperformed even if the remote controller is being oper-ated.

• In the case of simultaneous twin, triple and quad units,connect the controller to one indoor unit only. If con-nected to two or more indoor units, an error (operationstop) may occur.

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

• Use of optional "remote operation adapter" enablesremote control via relay. (Level signal)

Extraction of non-voltage contact output• Use of optional "remote operation adapter" and

"remote display panel" (installation required) pro-vides non-voltage contact outputs of signals (opera-tion, error) and operation/stop input function.

11-5. POWER OUTAGE AUTOMATIC RECOVERY OPERATION• 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 theunit 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 aclear determination of whether or not there was a power failure. When it has been determined that there has been a powerfailure, recovery will take approximately four minutes after the power is restored. Please wait. (Once "PLEASE WAIT" hasappeared 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.

11-6. 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 central-

ized 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 con-

trollers with 0.3 to 1.25 mm2 2-core cable.

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

11-7. COMBINED REMOTE/HAND-HELD 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 hand-held 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/hand-held selection switch and connect it to the CN32 connector on the printed circuit boardfor the indoor unit

W The AC for the control room is usually disconnected from the remote/hand-held control system.

11 Match the rated power supply voltage of the remote/hand-held selection switch and relay (X2) with the power supply for thecontroller.

22 When performing group control of multiple outdoor unit using a timer, be sure to arrange the timer so that all units do not startat 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 circuitbreaker to operate.

33 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.

44 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.
