1. Rotation number control of compressor
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
the 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 the compressor is controlled within the range shown in the table below. Howev-
er, the maximum rotation number is limited in the range shown in the figure below based on the
indoor fan mode and the outdoor temperature.
