Hi
When the compressor operates for 30 minutes continuously at over the maximum frequencyⅡ,
the maximum frequency is changed from the maximum frequencyⅠto the maximum frequencyⅡ.
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 frequency of the compressor.
* If the room temperature is 7°F(3.5°C) higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* When the room temperature is between +7°F(+3.5°C) to -1°F(-0.5°C) of the setting temperature,
the compressor frequency is controlled within the range shown in Table 1 .
However, the maximum frequency is limited in the range shown in Fig. 1 based on the
fan speed mode and the outdoor temperature.
* If the room temperature is 1°F(0.5°C) lower than a set temperature, the compressor will be
stopped.
