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 speed of the compressor.
* If the room temperature is lower by
speed will attain to maximum performance.
* If the room temperature is higher
* When the room temperature is between
the compressor speed is controlled within the range shown in Table2.
However, the maximum speed is limited in the range shown in Figure 2 based on the
fan speed mode and the outdoor temperature.
