Fujitsu ASU30RLE Service Instruction

1-2. HEATING OPERATION
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 lower 9°F(4.5°C) than a set temperature,
the compressor operation frequency will attain to maximum frequency.
If the room temperature is higher 1°F(0.5°C) than a set temperature, the compressor will be stopped.
When the room temperature is between +1°F(0.5°C) to -9°F(4.5°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table 2.

1-3. DRY OPERATION
The compressor rotation frequency shall change according to set temperature and room
temperature variation which the room temperature sensor of the indoor unit has detected
as shown in the Table 3.
