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 11 °F (6.0 °C) lower than a set temperature, the operation rotation num-
ber of compressor will attain to maximum performance.
If the room temperature is 2 °F (1.0 °C) higher than a set temperature, the compressor will be
stopped.
When the room temperature is within the range of +2 °F (1.0°C) to -11 °F (6.0°C) of the setting
temperature, the rotation number of compressor is controlled within the range shown below.
