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 fre-
quency of compressor.
• If the room temperature is 6.0 °C lower than a set temperature, the compressor operation frequen-
cy 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
compressor frequency is controlled within the range shown below.
• Compressor frequency range
