5-1. COOLING OPERATION
5-1-1 COOLING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit 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 degC higher than a set temperature,
the compressor operation frequency will attain to maximum performance.
* If the room temperature is 2 degC lower than a set temperature, the compressor
will be stopped.
* When the room temperature is between +2 degC to -2 degC 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.
