Hi
When the compressor operates for 30 minutes continuously at over the maximum frequency ,
the maximum frequency is changed from Maximum Frequency to Maximum Frequency .
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 4°F(2°C) higher than a set temperature, the compressor operation
frequency will attain to maximum performance.
* When the room temperature is between +4°F(+2°C) to -5°F(-2.5°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 5°F(2.5°C) lower than a set temperature, the compressor will be
stopped.
