Fujitsu AOYG24KATA - Compressor Frequency Control; Cooling Operation

1. Compressor frequency control
1-1. Cooling operation
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 6.0 °C higher than a set temperature, the compressor operation fre-
quency 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 within the range of +6.0°C to -1.0°C of the setting temperature, the
compressor frequency is controlled within the range shown in the table below. However, the maxi-
mum frequency is limited in the range shown in the figure below based on the indoor fan mode
and the outdoor temperature.
