NOTES :

1. Since the indoor fan motor (MF) is connected with 230, 240V power. If 220V
power is used, change the dip switch (SW8) on the indoor controller board
as shown in fig : w2.

4. Emergency operation
If remote controller or microcomputer fails but there is no other trouble ,
emergency operation is possible by setting dip switch (SW3<I.B>) on the
indoor controller board.

[Check items]

(1)Make sure that no other trouble exist the outdoor unit. Trouble with the out-

door unit prevents emergency operation.
(If any trouble exists the outdoor unit error code “P8”will be displayed on the
remote controller and the trouble position will be shown on the outdoor con­troller LED. See electric wiring diagram of the outdoor unit for details.)

(2)Make sure that there is no trouble with the indoor fan.

56

Emergency operation will be continuous run with power ON/OFF (ON/OFF
with the remote controller is not possible).

[Emergency operation procedure]

(1)Set the dip switch (SW3<I.B>) on the indoor controller board to 1 on and 2

off for cooling.

(2)Turn on the outdoor unit side circuit breaker, then the indoor unit side circuit

breaker.

(3)During emergency operation indoor fan runs at High speed but auto-vane

does not work.

(4)Thermostat will not function. Cold air blows out for defrosting during heating

thus do not operate defrosting for a long time.

(5)Emergency cooling should be limited to 10 hours maximum.

(The indoor unit heat exchanger may freeze).
(6)After every emergency operation, set all dip switches (SW3<I.B>) to OFF.
(7)Movement of the vanes does not work in emergency operation, therefore you

have to slowly set them manually to the appropriate position.
NOTE: If the drain water lift up mechanism is identified to be defective with the

microcomputer doctor during cooling, do not use emergency operation
(it causes drain overflow)

1 3-minute time delay

To prevent overload, the compressor will not start within 3 minutes after stop.

2 The compressor runs when room temperature is higher than set temperature.

The compressor stops when room temperature is equal to or lower than the set temperature.
The compressor maintains the previous state when the discharge temperature minus the set temperature is 0°C or
more, or lower than 1°C.

3 The compressor stops in check mode or during protective functions.
4 Coil frost prevention

To prevent indoor coil frost, the compressor will stop when the indoor coil thermistor (RT2) reads 1°C or below after the
compressor has been continuously operated for at least 16 minutes or more. When the indoor coil temperature rises to
10°C or above, the compressor will start in a 3-minute(w2) time delay.
w2 When the indoor coil temperature is -1°C or less, the compressor starts in 6 minutes.

When indoor coil temperature becomes -15°C or below,coil frost protection will proceed as follows.

<Start condition>

After the compressor has been continuously operated for 3 minutes or more,and the indoor coil temperature has been

-15°C or below for 3 minutes,the coil frost protection will start.

<Coil frost protection>

Compressor stops for 6 minutes,and then restarts.
lf the start condition is satisfied again during the first 10 minutes of compressor operation,both the indoor and outdoor
units stop, displaying a check code of “P6” on the remote controller.

<Termination conditions>

Coil frost protection is released when the start condition is not satisfied again during the allowance, or when the COOL
mode stops or changes to another mode.

(2) Indoor fan control

Indoor fan speed LOW/HIGH depends on the remote controller setting.
However, if an outdoor unit abnormality is detected, the indoor fan speed will be LOW, regardless of the remote controller
setting.

(i ) Fan speed LOW/HIGH depends on the remote controller setting regardless of the thermostat ON/OFF.
(ii) Fan speed will remain on LOW if an abnormality in outdoor unit is detected. (5 minutes)

NOTE : Fan stops immediately if the unit stops or the check mode is started.

(3) Auto vane control

Auto vane position is set to 30 degrees airflow at the start-up of COOL operation.

(4) Detecting abnormalities in the outdoor unit

After the compressor has been continuously operated for 3 minutes, if the difference between the indoor coil temperature
and room temperature is out of RANGE C for 1 minute, the indoor fan speed will turn to LOW. Five minutes later, if the dif­ference is still out of RANGE C,the outdoor unit is functioning abnormally. Thus, the compressor stops and check code
“P8” appears on remote controller.
RANGE A: Indoor coil temperature is more than 5 degrees above room temperature.
RANGE B : Indoor coil temperature is within 5 degrees either way of room temperature.
RANGE C : Indoor coil temperature is more than 5 degrees below room temperature.

(5) Drain pump control

The drain pump works in COOL or DRY operation.
The drain pump does not work in check mode.

<Drain sensor>

When both the drain pump and unit are operating, the drain sensor detects the temperature. This temperature tells
whether the drain water level is above or under the drain sensor. If the drain water level rises above the drain sensor due
to a drain pump malfunction, the unit will stop operating in order to prevent drain from overflowing. The check code “P5” on
the remote controller will display this occurrence.

(6) Dew prevention heater

To prevent dew from accumulating on the grille, the dew prevention heater is continuously ON during COOL operation.
It is independent of the thermostat ON/OFF.

code

(2) When one remote controller controls several units in the group con-

trol, the LCD shows the unit address and check code of the first mal­functioning unit.

(3) To cancel the check mode, press the ON/OFF button. In remote

ON/OFF control, press the remote ON/OFF switch. In centralized
control, turn OFF the ON/OFF button of centralized controller.

NOTE: The latest check code is memorized, even if the check mode is cancelled by the way mentioned above. It takes

60 seconds maximum to display the memorized check code.

[This figure shows the remote controller for PL-AK.]

2-2 How to use the self diagnostic function for service

A. For normal control with one unit and one remote controller

(1) Pressing the CHECK button on the remote controller twice starts the self diagnostic function.
(2) During the self diagnostic function, “CHECK MODE” appears at two positions on the remote controller display. Then, at

least 10 seconds later, the unit address and the check code is alternately displayed at one-second intervals.

(3) Check and repair the unit according to the check code. (Refer to page 51.)

B. For group control using one remote controller

(1) Pressing the CHECK button on the remote controller twice starts the self diagnostic function.
(2) Press the TEMP. button or TEMP. button on the remote controller to advance or go back to the unit address.

Each time TEMP. button is pressed, the unit address advances by one. Each time TEMP. button is pressed,
the unit address goes back by one.
The check code and the unit address, appear alternately.

(3) The check code “U8” means no malfunction has occurred since installation.

The check code “EO” means the following conditions:

● The unit address displayed on the remote controller does not apply to any unit.

● power is not supplied to the unit.

● Signal transmitting/receiving circuit is abnormal.

(4) Check and repair the unit according to the check code. (Refer to page 51.)

3 Both remote

ON/OFF and indi­vidual controls
(See page 63.)

4 Individual control

by grouping
remote controllers
(See page 64.)

Many units, installed at different locations, can be started
and controlled with a single remote controller. The remote
controller can be mounted in a different location using a
non-polar two-wire cable, which can be extended up to
500m. Amaximum of 50 units can be controlled with a
single remote controller. All units operate in the same
mode.

Two remote controllers can be used to control either one
unit or a group of units. Units can then be controlled from
a distance or at close range. Units operate according to
the latest command from either remote controller.

All units can be turned on or off simultaneously using a
remote ON-OFF switch. Also, each unit can be controlled
individually by each remote controller. Dunning remote
ON-OFF control, a message of “CENTRALLY CON­TROLLED” is displayed on the LCD of the remote con­troller.
This is available for both one unit control and several units
control.

By grouping the remote controllers in one place, several
units installed at different locations can be controlled indi­vidually, and operation conditions of all units are visible
without a special control board. The control method is the
same as that of the single unit with a single remote con­troller.

(See page 65.)

Several units can be controlled with a remote control dis­play board. Operation conditions of all the units are visi­ble with the remote control display board.
Individual control by each remote controller is also possi­ble.

A unit can be started or stopped with the circuit breaker
on or off.
Remote controller is also available.
With this function, when the power is restored after power
failure, the unit will restart automatically. (However, when
the remote controller POWER ON/OFF button is OFF, the
unit will not start.)

2-1 How to wire

(1) Connect the remote controller to the double terminal block

on the indoor controller board of the master unit (No.0 unit).
(See Figure 1.)

(2) Connect the double terminal block of the master unit to the

double terminal block of No.1 unit.

(3) Connect the double terminal block of No.1 unit to the dou-

ble terminal block of No.2 unit.

(4) Continue the process until all the units are connected with

two-wire cables. (See Figure 2.)

(5) Remove the connector CN40 from the indoor controller

board of each unit except the master unit. (See Figure 3.)

(6) Set the unit-address of each unit with SW2 on the indoor

controller board following the instructions below.

2-2 How to set unit-address

The unit-address also serves as a successive-start timer which
starts each unit at intervals of 1 second. If two or more units
have the same unit-address in a group control, operation stops
due to system error. Be sure to set SW2 correctly following the
instructions below.
(1) Each lever of SW2 shows the number as follows.

SW2-1 : 1 SW2-4 : 8
SW2-2 : 2 SW2-5 : 16
SW2-3 : 4 SW2-6 : 32

(2) Total number of levers turned to ON shows the address of

the unit.
For example, to set No.3 unit, turn ON SW2-1 and SW2-2.

(3) In this way, set from the master unit to the last unit.

Do not forget to set the master (No. 0) unit.

CONTROL USING TWO REMOTE CONTROLLERS : OPTIONAL REMOTE CONTROLLER

(PAR-JA240KA)

Two remote controllers can be used to control either one unit or a group of units. Units operate according to the latest com-

mand from either of the two remote controllers.

Before operation, be sure to set one remote controller as the “main controller” and the other as the “sub controller”, using dip

switch SW17-7 of the remote controller.

3-1 How to set SW17-7 (See Figure 5.)

(1) For the main remote controller, turn SW17-7 OFF.
(2) For the sub remote controller, turn SW17-7 ON.

3-2 Remote controller LCD indication

(1) The same indications always appear on both the

main and sub remote controllers, except during the
timer operations.

(2) Timer operations can be set with either of the two

remote controllers. However, LCD indication appears
only on the remote controller used for timer-settings.

(3)If both remote controllers are set for timer operation

with different time-settings, the timer operation with
the shorter remaining-time is effective.

(4) Self-diagnostic function is available with either of the

two remote controllers. If one of the remote con­trollers is used for the self-diagnostic function, the
other remote controller displays the check mode.
If the self-diagnostic function is reset by either of the
two remote controllers, both remote controllers are
reset.

4. REMOTE ON-OFF AND INDIVIDUAL REMOTE CONTROLS

This method is available to control one unit or any number of units.
The following operations are available by connecting a relay, a timer adapter (PAC-SA89TA-E), and a remote ON/OFF switch

to the system. Timer adapter is an optional part. Other parts are available on the market.
(A) To start all units in order by remote ON-OFF switch
(B) To stop all units simultaneously by remote ON-OFF switch
(C) To switch between the remote ON-OFF control and the individual remote control

4-1 System

Figure 6 shows the case of three units. The same is the case with any number of units.

NOTE2 : For control circuit wiring, use a wire of No. 14 AWG or a control cable according to the power supply of control

circuit.

NOTE3 : When the power supply of the control circuit is 220/240V AC,

● Do not connect the control circuit wire to the remote controller cable directly.

● Do not place the control circuit wire and the remote controller cable into the same conduit tube.

4-2 Basic wiring

Note : Before starting all units simultaneously by the remote ON-OFF switch, be sure to connect a sequence-start timer

into the remote ON-OFF circuit. Otherwise, a rush of starting current may damage the power supply.

w2 After all units stop at once, if SW2 is turned OFF, each unit can be individually started by each remote controller.

5. INDIVIDUAL CONTROL BY GROUPING THE
REMOTE CONTROLLERS

● Grouping the remote controllers allows individual control and cen-

tralized monitoring of units installed in different places without a
special control board.

● Remote control cables are extendible up to 500m. When the cable

length exceeds 12m, use the double-insulated two-care cable such
as Belden 9407. Also, the cable thickness must be No. 22 AWG or
above.

● When gathering the power ON/OFF switches of air conditioners

near the remote controllers, you should also install the power
ON/OFF switch near each unit to prevent electric trouble during
servicing.

You can control several units with a multiple remote control display, by
wiring an optional multiple display adapter (PAC-SA88HA-E) with relays
and lamps on the market.

6-1 How to wire

(1) Connect the multiple display adapter to the connector CN51 on the

indoor controller board.

(2) Wire three of the five wires from the multiple display adapter as shown

in the figure below.

Indoor controller board

[Notes on Signs]
X1:Relay (for operation lamp)
X2:Relay (for check lamp)
RL:Operation Lamp
GL:Check Lamp
[Field supplied parts]

Relays:12V DC with rated coil power

consumption below 0.9W.

Lamps:Matching to power supply voltage.

7. AUTO RESTART FUNCTION

By setting the dip switch SW1-8 to ON, the air conditioner can be started/stopped by power supply ON/OFF.
If the air conditioner is OFF before the power failure, it will not start operation by power restore.

•This function is mainly to emergency performance when the power supply stops temporarily. Therefore, since the protec­tion function (for example, clank case heater and prevention from restarting in 3 minutes, etc.) of the device is not operat­ed, this function should not be used mostly.

8. TIMER OPERATION OR THE OPERATION BY AN EXTERNAL SIGNAL

<Wiring>

For remote control, connect the optional timer adapter (PAC-SA89TA-E)
