(2) When Troom temperature Ttemperature setting, the air conditioner is running in the heating mode.
Once a run mode is determined, it must not be changed within 30 minutes except that following conditions
are met: When in the automatic cooling mode,
Troom temperature Ttemperature setting -3, the air conditioner immediately enters the heating mode, or
when in the automatic heating mode, Troom temperature Ttemperature s3, the air conditioner
immediately enters the cooling mode.
2. Cooling mode
(1) The airflow rate of the indoor fan can be set by the remote controller:
a. Model KFR-28GW/BPx2/2801 GW/BPx2
Low: 900 rpm Medium: 1,100 rpm High: 1,200 rpm High efficiency: 1,300 rpm
b. KFR-2601 GW/BPx2

The target frequency at which the compressor runs is determined by the difference between the
temperature setting and actual room temperature. Larger the difference, higher the frequency. The
voltage is available by referring to the V/F curve of the compressor.
