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
rotation number of the compressor.
• If the room temperature is 6.0 °C higher than a set temperature, the operation rotation number of
compressor 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
rotation number of compressor is controlled within the range shown in the table below. However,
the maximum rotation number is limited in the range shown in the figure below based on the in-
door fan mode and the outdoor temperature.
