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 +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.
* If the room temperature is some degrees lower than a set temperature,
the compressor will be stopped.

* If the room temperature is 2°C(4°F) 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.
