Fujitsu ASUG09LZBS - Heating Operation

1-2. Heating operation
A sensor (room temperature thermistor) built in indoor unit body will usually perceive difference or
variation between setting temperature and present room temperature, and controls operation rota-
tion number of compressor.
• If the room temperature is 6.0°C lower than a set temperature, the operation rotation number of
compressor will attain to maximum performance.
• If the room temperature is 1.0°C higher than a set temperature, the compressor will be stopped.
• When the room temperature is within the range of +1.0°C to -6.0°C of the setting temperature, the
rotation number of compressor is controlled within the range shown below.
