( Fig.1 : Outdoor temperature zone )
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.

* When the room temperature is between +6°C to -1°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 Fig.1 based on the indoor
fan mode and the outdoor temperature.
* If the room temperature is some degrees lower than a set temperature,
the compressor will be stopped.

* If the room temperature is 6°C higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
When the compressor operates for 30 minutes continuously at over the maximum frequency ,
the maximum frequency is changed from Maximum Frequency to Maximum Frequency .

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 6°C 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 +1°C to -6°C of the setting temperature,
the compressor frequency is controlled within the range shown in Table 3.

When the air conditioner is set to the AUTO mode by remote control, operation starts in the optimum
mode from among the Heating, Cooling, and Monitoring modes.
During operation, the optimum mode is automatically switched in accordance with temperature changes.
The temperature can be set between 18 C and 30 C in 0.5 C steps.

5. INDOOR FAN CONTROL
The airflow can be switched in 5 steps such as Auto, Quiet, Lo, Me, Hi, while the indoor fan only runs.
When fan mode is set at [Auto], it operates on [Me] fan Speed.

3. COOLING OPERATION
Switch the airflow [Auto], and the indoor fan motor will run according to a room temperature,
as shown in Fig4.
On the other hand, if switched in [Hi] [Quiet], the indoor motor will run at a constant airflow of [Cool]
operation modes Quiet, Lo, Me, Hi, as shown in Table 5.
