7.CONTROL MODE
4. Heating mode
(1) If Tindoor coil pipe 38 , the indoor fan runs according to the airflow settings on 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
Low: 1,350 rpm Medium:1,500 rpm High: 1,600 rpm High efficiency: 1,700 rpm
23 T indoor coil pipe 38 , the airflow varies from the ultra-low to low rate in stepless change.
Higher the temperature is, greater the airflow rate.
T indoor coil pipe 23 , the fan stops.
(2) The indoor throttle motor is controlled according to the settings on the remote controller. Refer to the
Use and Installation Manual.
(3) Control of compressor
The compressor's target operating frequency is determined by the difference between the temperature
settings and the actual room temperature. Greater the difference is, higher the frequency.
The voltage is available by referring to the V/F curve of the compressor.
