2-2 DRY operation
On the switch on, the compressor always starts to
operate for 2 minutes with fan speed "DL" .
The microcomputer reads the room temperature 2
minutes after this first compressor operation.
This room temperature is set as the preset
temperature automatically.
The preset temperature ranges from 18˚C to
32˚C. When the room temperature is below 18˚C,
the preset temperature is set to 18˚C, and when
the room temperature is over 32˚C, the preset
temperature is set to 32˚C.
Dry operation is divided into three zones (Cooling
zone, Dehumidifying zone and Circulating zone)
by thermostat lines (D1 to D3), and the
compressor and the fan motor are controlled in
each zone as shown in Table Y-1.

4. Hot-Keep
This function automatically controls the on-off
operation of the indoor fan motor in accordance
during the heating operation, thereby preventing
the air conditioner from delivering a cold air when
the compressor is off.
When the room temperature exceeds the
thermostat line “H1”, the compressor is turned off,
and the indoor fan motor is turned off after
rotating at “HUL” for 30 seconds. 3 minutes and
10 seconds after turning off the compressor, the
indoor fan motor is turned on for 3 minutes and 20
seconds. At 10 seconds after turning on the
compressor, the indoor fan motor is turned on.
The next compressor OFF time is for 3, 8 or more
than 8 minutes according to the room temperature
(the time increases with a rise of room
temperature) when 3 minutes elapse after turning
on the compessor.
Figure Y-7
5. Preheat air flow
This function is intended to prevent cold air from
being discharged when the heating operation
starts or when defrosting.
When the indoor pipe temperature is below 29˚C
at the begining of the heat operation or after
defrosting, the indoor fan motor stays.
When the indoor pipe temperature gets higher
than 29˚C, the fan motor is turned on at speed
“HUL” after compensation of starting.
When the indoor pipe temperature exceeds 35˚C,
the specified fan speed is restored. When the
indoor pipe temperature falls below 30˚C, the fan
speed shifts down to "HUL". And, when the indoor
pipe temperature falls below 23˚C, the fan motor
turns off. Then, over 29˚C , it turns on again at
speed “HUL”.

6. Overheating protection system
When overloading occurs during the heating operation,
this system controls the outdoor fan motor according to
the indoor pipe temperature to prevent the overloading
of the compressor and restrain the rise in high pressure.
When the indoor pipe temperature exceeds U1˚C, the
outdoor fan motor is turned off, and when the indoor
pipe temperature falls U2˚C, the outdoor fan motor turns
on.

7. Current control
This system, in order to prevent overcurrent
during heating operation, controls the outdoor fan
motor and changes the indoor fan motor speed by
detecting total current. When the current exceeds
P2, the outdoor fan motor is automatically turned
off, and when the current falls below P4, the
outdoor fan motor is turned on.
When the current exceeds P3 and the indoor fan
speed shifts down because of cold air (5. Preheat
air flow), the changes in the indoor fan speed
shifts up as follows, from "off" to "HUL", or from
"HUL" to "HL". And when the current falls bellow
P5, the indoor fan speed shift up is canceled.
Figure Y-10
8. Freeze preventive
When the indoor pipe temperature falls below 0˚C
during cool operation or dry operation, the
compressor is turned off.
9. Defrost
The defrost timer (integrating the operation time of
compressor) counts time with microcomputer
during heat operation.
Frost of outdoor pipe is estimated by indoor pipe
temperature (TH2), room temperature (TH1),
indoor fan speed and operation state of
compressor.
In the defrost operation, first the compressor is
turned off, the fan speed is set to “HUL” and the
outdoor fan motor is turned off.
30 seconds later the indoor fan motor is turned
off, 60 seconds later the reverse valve is turned
off, and the compressor is turned on. In the end of
defrosting, the compressor is turned off, the
outdoor fan motor is turned on, 60 seconds later
the reverse valve is turned on, and the
compressor is turned on, starting heat operation.
At this time, the indoor fan motor is turned off or
the fan speed is set to “HUL” if preheat air flow
function is effective.

10. Delayed operation of the reverse valve
the heat operation is shut down or the operating
mode is switched from heat to cool or dry, or vice
versa, the reverse valve is switched after 3
minutes.
11. Test run
If the "AUX" button on the unit is pressed for 5
seconds or more during operation, cool test
operation starts. The operation LED (red) flickers
during test run.
To put the system in the heating test run mode,
start the cooling operation and select the heating
mode on the remote control. In cool and heat
mode continuous compressor on operation is
performed. In dry mode the operation is in
dehumidifying zone. In fan only mode the indoor
fan motor runs continusly.
12. Timer
12-1 ON/OFF TIMER
When the unit operates during one hour after the
OFF-time is set, thermostat setting is
automatically shifted (+1˚C in cool operation and
dry operation, -3˚C in heat operation, 16˚C 32˚C). When the ON-timer is set in heat operation
and cool operation, operation starts before 0 to 30
minutes(depends on the room temperature) so
that preset temperature is obtaind at set time.
12-2 ONE-HOUR TIMER
When ONE-HOUR timer is set, the unit turns off
automatically after one hour. The one hour timer
operation has priority over other time operation,
such as the TIMER ON and TIMER OFF. If the
ONE-HOUR TIMER button is pressed again
during operation, the unit will operate additionally
for another one hour.

20. Diagnosis procedure
When indoor fan motor is out of order or compressor lock occurs, the compressor, indoor fan motor, outdoor
fan motor, and louver are all stopped and the operation LED(red) turns on or off synchronously with the timimg
of the timer LED.
When the thermistor for room temperature or pipe temperature is open or short state, the operation LED turns
on or off synchronously with the timing of the timer LED by pushing continously for more than 5 seconds
"AUX." button during suspension of operation.
Timing chart of Timer LED and Operation LED of DIAGNOSIS PROCEDURE.
When "OI" button the remote controller or "AUX." button in the unit is pushed, the unit is free from
DIAGNOSIS PROCEDURE.
When the louver unit is not properly installed, all lamps on the indicator panel will blink, operation are all stop
and Remote signal is not accept.
