Remote controller

1. ADVANCED REMOTE CONTROLLER

(1) Ultra-thin 12mm (1/2”) remote controller

The streamelined, square controller is designed to blend with any inte­rior. Also, the sophisticated microprocessor allows you to easily carry
out a wide range of operations.

(2) Attractive LED display

Every operation condition is indicated on the LED display.

(3) Simultaneous display of set temperature and room temperature

The set temperature is indicated by continuous light and the room tem­perature is indicated by a flashing light. In this way, accurate tempera­ture conditions are always available at a glance and fine temperature
regulation is possible.

(4) Convenient 12-hour ON-OFF timer

The timer switches on and off automatically at the times you set. Once
the timer is set, the remaining time is shown on the LED display.

(5) Self-diagnostic feature indicates faults instantly

If a problem occurs, the unit will stop operating and the temperature
display will change to a self-diagnosis indicator, which shows the loca­tion of the trouble.

(6) Useful memory feature for storing instructions

The previous set value is memorized so that constant temperature control can be achived. For example, if a power fail­ure occurs, the temperature will not have to be readjusted afterwards.

(7) Cables between remote controller and indoor unit

The polar, 12-core type remote controller cables makes installation simple and troublefree. Also, the cables can be
extended up to 50m. (optional)

1. AIR OUTLET

New PC series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by auto vane)
instead of 2 (horizontal, and down flows).

2. EASY TO CLEAN ; FLOCKLESS VANE

With our original air current control mechanism, a flockless vane is
newly adapted.
The flockless vane prevents the condensation on the vane.
By changing the vane to the flockless type, the unit can be cleaned
much easier with mild household detergent.

3. NEW MATERIALS FOR BETTER OIL RESISTANCE

We have changed the materials of grill, filer, fan and fan casing from ABS to P.P. (polypropylene) for better oil resistance. As
a result, oil crazing is cut in half.

4. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)

Simplified the installation work by changing the suspending method to the direct suspending method (suspending the unit
directly from the suspension fixture).
In this way, the unit can be attached to the suspension fixture without removing the installation parts off (Only the side cover
is removed). This method is much simpler than the ¨One-time installation method¨.

5. IMPROVING EFFICIENCY OF PIPING WORK

New PC series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by auto vane)
instead of 2 (horizontal, and down flows).

1 Removed the knockout work by separating the piping space

from the air outlet for efficiency of the piping work.

w Knockout work is needed for the top part. When optional

drain-up machine is installed, the refrigerant pipe exits out
from the top.

2 Improved the flexibility by making it possible for drainage

pipe to exit not only from the right side back but also from
the left side back.

6. QUITENESS ; 43dB : PC-3GJA1(HIGH NOTCH)

Auto vane

Swing

Quiteness of the New PC series product is significant. It is because we have adapted the new shape air outlet and changed
the air coures.

7. EASY MAINTENANCE ; NO MAINTENANCE NECESSARY FOR 2500 HOURS

The new long-life air filter can be used continuously 2500 hours without maintenance (at general office situation).

8. CHOICE OF FILTER

High performance filter can be purchased optionally for the special needs.

The unit of pressure has been changed to MPa based on SI(International System of unit) in accordance with I.S.O.(International
Organization for Standardization).

The conversion factor is : 1(MPa•G)=10.2(kgf / FF•G)

3. OUTLET AIR SPEED AND COVERAGE RANGE

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

[Emergemcy operation procedure]
(2) Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker in this order.
(3) During emergency operation, indoor fan runs at high speed but automatic vane remains stop.
(4) If vane closed, open the vane by hand slowly.
(5) Thermostat will not function.
(6) Emergency cooling should be limited to 10 hours maximum (The Indoor unit heat exchanger may freeze).
(7) If the ,microcomputer doctor detects the abnomality of the drain-up machine during cool mode. do not execute emergency operation (It causes drain overflow).

NOTES :

1. Since the indoor fan motor (MF) is connected with 220V power, using 230, 240V power will require a setting change of the dip switch (SW1<I.B>) on the indoor controller board
as shown in fig : w1.

fig : w1

Indoor fan motor (MF) for 230, 240V.

2. Since the indoor transformer (T) is connected with 220V power, if 230, 240V power used. Change the wiring connection showing fig : W2.

fig : w2

When power supply is

3. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.

4. Symbols used in wiring diagram above are. : Connector , : Terminal block

5. 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)Compressor and fan.
(2)Check the abnomality using self diagnostic function. When the result of self diagnosis indicates protective device such as freeze protection, emergency operation is not possible

unless the cause is removed.

(3)Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with remote controller is not possible).

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.

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. The coil frost prevention is released under any
of the following conditions.

● The indoor coil thermistor rises to 10°C or above.

● The room temperature becomes equal to or lower than the set temperature.

● COOL mode is stopped or changed to another mode.

NOTE : By cutting the jumper wire JRO2 on the indoor controller board, the temperature to start coil frost prevention

changes from 1°C to -3°C.

5 Coil frost protectiony

24

When indoor coil temperatuer 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.
If 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.

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.

(3) Louver control

Louver operation (SWING LOUVER ON / OFF) depends on the remote controller setting.
w Louver comes to the holizontal position automatically after 1 hour operation in law mode.

(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 will stops and the remote
controller still display this occurrence.
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 tempetature.

(5) Drain pump control

The drain pump works in COOL or DRY operation. When COOL or DRY operation stops or changes to another mode, the
drain pump continues to operate for 3 more minutes.

<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 enter the check mode. The operation will stop and only the drain pump will con­tinu to operate for 3 more minutes. When either of the following conditions are satisfied, the drain sensor is deamed to be
under water.

● Though the drain sensor has been heated by the drain sensor heater for more than 40 seconds, its temperature rise is
less than 20 degrees.

● The drain sensor temperature is below 63°C.

Connection method

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 5m, 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), connecting cables.

"ENGAGED" indicator
When this indicator is lit, transmission is in

progress and all switches are inoperative.

DUAL/CENTRAL switch
This change-over switch governs the oper-

ation of the accessory remote controller.

"DUAL"
Instructions from both the accessory

remote controller and the centralized
remote controller are valid. (Priority is
given to the last instruction received.)

"CENTRAL"
ON/OFF switching by the accessory

remote controller is invalidated. Operation
is controlled by the centralized remote con­troller only.

Initial setting is "DUAL".

LCD Matrix Display
This display indicates the operational sta-

tus of all connected units either by steady
lighting or by flashing.

▲BACK ▼AHEAD buttons
These buttons are used to designate
the attached unit(s). (They designate
the unit to be centrally controlled.)

●When group “00” is designated; col­lective ON/OFF instruction is sent to all
units.

●When group “01”-“16“ is designated;
ON/OFF instruction is sent to the des­ignated units.

ACTIVE/BYPASS switch
This change-over switch for the pro­gram timer.
Use “ACTIVE” when a program timer is
connected.
Use “BYPASS” when a program timer
is not connected.

Independent “DUAL / CENTRAL” and “ACTIVE / BYPASS” setting of all the groups is possible. When the power supply to the

centralized remote controller is cut, due to power failure, all settings will return to original “DUAL” and “BYPASS”.

the dipswitch when a centralized remote controller is
being used.
The address is the control number of each unit in the
centralized control system.
As the address serves as a time-delay device as
well, sequential starts (all units are triggered collec­tively by one single ON instruction)must be set with
different address numbers (greater than 0) for each
