( Fig. 1 : Limit of Maximum Frequency based on Outdoor Temperature )
1. COOLING OPERATION
1-1 COOLING CAPACITY CONTROL
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 4°F(2°C) higher than a set temperature, the compressor operation
frequency will attain to maximum performance.

* When the room temperature is between +4°F(+2°C) to -5°F(-2.5°C) 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 Figure 1 based on the
fan speed mode and the outdoor temperature.
* If the room temperature is 5°F(2.5°C) lower than a set temperature, the compressor will be
stopped.

2. HEATING OPERATION
2-1 HEATING CAPACITY CONTROL
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 6°F(3°C) than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 5°F(2.5°C) than a set temperatire, the compressor will be
stopped.
* When the room temperature is between +5°F(+2.5°C) to -6°F(-3°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table2.
However, the maximum frequency is limited in the range shown in Figure 2 based on the
fan speed mode and the outdoor temperature.
( Table 2 : Compressor Frequency Range )
( Fig.2 : Limit of Maximum Frequency based on Outdoor Temperature )
* The room temperature is controlled 4°F(2°C) higher than the setting temperature for 60 minutes
after starting the operation.
After 60 minutes, it is controlled based on the normal setting temperature.

3. DRY OPERATION
3-1 INDOOR UNIT CONTROL
The compressor rotation 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 3.
However, after the compressor is driven, the indoor unit shall run at operation frequency of
64Hz (for ASU9RL) or 61Hz (for ASU12RL), for a minute.

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 64°F(18°C) and 86°F(30°C) in 2°F(1°C) steps.
When operation starts, only the indoor and outdoor fans are operated for 1 minute. After 1 minute,
the room temperature and outside air temperature are sensed and the operation mode is
selected in accordance with the table below.
