1 . DESCRIPTION OF EACH
CONTROL OPERATION
1. COOLING OPERATION
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is 2°C(4°F) higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is some degrees lower than a set temperature,
the compressor will be stopped.
* When the room temperature is between +2°C(4°F) to -2.5°C(-5°F) of the setting temperature,
the compressor frequency is controlled within the range shown in Table1.
However, the maximum frequency is limited in the range shown in Fig.1 based on the indoor
fan mode and the outdoor temperature.

2. HEATING OPERATION
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation frequency of the compressor.
* If the room temperature is lower by 3°C (6°F) than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is some degrees higher than a set temperature,
the compressor will be stopped.
* When the room temperature is between +2.5°C (+5°F) to -3°C (-6°F) of the setting temperature,
the compressor frequency is controlled within the range shown in Table 3.
However, the maximum frequency is limited shown in Table 4 based on the fan mode.

The compressor frequency shall change according to the temperature, set temperature,
and room temperature variation which the room temperature sensor of the indoor unit body has
detected as shown in the Table 5.
However, after the compressor is driven, the indoor unit shall run at operation frequency of
(09 : 52 rps, 12 : 61 rps) for 60 seconds.

4. AUTO CHANGEOVER OPERATION
When the air conditioner is set to the AUTO mode by remote control, operation starts in the optimum
mode from among the Heating, Cooling, Dry and Monitoring modes.
During operation, the optimum mode is automatically switched in accordance with temperature changes.
The temperature can be set between 18°C (64°F) and 30°C (88°F) in 1°C (2°F) steps.

*The outdoor fan speed mentioned adove depends on the compressor frequency.
(When the compressor frequency increases, the outdoor fan speed also changes to the higher
speed. When the compressor frequency decreases, the outdoor fan speed also changes to the
lower speed.)
*After the defrost control is operated on the heating mode, the fan speed keeps at the higher speed
as table 10 without relating to the compressor frequency.

If the sleep is set, the room temperature is monitored and the operation is stopped automatically.
If the operation mode or the set temperature is change after the sleep timer is set, the operation is
continued according to the changed setting of the sleep timer from that time ON.
In the cooling operation mode
When the sleep timer is set, the setting temperature is increased 1°C (2°F).
It increases the setting temperature another 1°C (2°F) after 1 hour.
After that, the setting temperature is not changed and the operation is stopped at the time
of timer setting.

The compressor won't enter operation status for 2 minutes and 20 seconds after the compressor is stopped,
even if any operation is given.
11. FOUR-WAY VALVE EXTENSION SELECT
At the time when the air conditioner is switched from the cooling mode to heating mode, the
compressor is stopped, and the four-way valve is switched in 2 minutes and 20 seconds later after
the compressor stopped.
12. AUTO RESTART
When the power was interrupted by a power failure, etc. during operation, the operation contents
at that time are memorized and when power is recovered, operation is automatically started with
the memorized operation contents.
When the power is interrupted and recovered during timer operation, since the timer operation time
is shifted by the time the power was interrupted, an alarm is given by blinking (7 sec ON/2 sec OFF)
the indoor unit body Timer lamp.

They blink for 1 second ON and 1 second OFF on both Operation lamp and Timer lamp (same as test operation).
Forced cooling operation is released after 60 minutes of starting operation or pressing MANUAL AUTO button
for 3 seconds or pressing START/STOP button on the remote controller.
15. COMPRESSOR PREHEATING
When the outdoor heat exchanger temperature is lower than 5°C and the all operation has
been stopped for 30 minutes, power is applied to the compressor and the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started, and when the outdoor temperature rises to 7°C (44.6°F) or greater,
preheating is ended.
16. ECONOMY OPERATION
The ECONOMY operation functions by pressing ECONOMY button on the remote controller.
At the maximum output, ECONOMY Operation is approximately 70% of normal air conditioner operation
for cooling and heating.
The ECONOMY operation is almost the same operation as below settings.
