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 2 C higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is 2.5 C lower than a set temperature, the compressor will be
stopped.
* When the room temperature is between +2 C to -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.

( Table 1 : Compressor Frequency Range )
( Fig. 1 : Limit of Maximum Frequency based on Outdoor Temperature )
When the compressor operates for 30 minutes continuously at over the maximum frequency ,
the maximum frequency is changed from Maximum Frequency to Maximum Frequency .
The room temperature is controlled 1 C lower than the setting temperature for 40 minutes
after starting the operation.
After 40 minutes, it is controlled based on the normal setting temperature.

2. HEATING OPERATION
2-1 HEATING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive

controls the operation frequency of the compressor.
* If the room temperature is lower by 3 C than a set temperature, the compressor operation
frequency will attain to maximum performance.
* If the room temperature is higher 2.5 C than a set temperatire, the compressor will be
stopped.

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 58Hz, for a minute.
