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.

* When the room temperature is b2°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.
* If the room temperature is 2.5°C lower than a set temperature, the compressor will be
stopped.
