Fujitsu ARYG72LHTA Service Instruction

1-2. COOLING OPERATION
1-2-1 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 6.0°C higher than a set temperature,
the compressor operation frequency will attain to maximum performance.
* If the
room temperature is 1.0°C lower than a set temperature, the compressor
will be stopped.
* When the room temperature is between +6.0°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 Fig.1 based on the
fan speed mode and the outdoor temperature.
