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 6.0°C higher than a set temperature, the compressor operation
frequency will attain to maximum performance.

* When the room temperature is b6.0°C to -1.0°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 Figure1 based on the
fan speed mode and the outdoor temperature.
* If the room temperature is 1.0°C lower than a set temperature,
the compressor will be stopped.
