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 11 °F (6.0 °C) higher than a set temperature, the operation rotation
number of compressor will attain to maximum performance.
• If the room temperature is 2 °F (1.0 °C) lower than a set temperature, the compressor will be
stopped.
• When the room temperature is within the range of +11 °F (6.0 °C) to -2 °F (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 indoor fan mode and the outdoor temperature.
