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.
