8.2.15. High Pressure at Minimum Frequency Control
This type of control is applicable on Cooling Mode and Soft Dry Mode operation only.
1. When outdoor air temperature increases to 38.6°C, compressor operating frequency reduces to minimum of 30 Hz and 32 Hz
for E9BKP and E12BKP respectively.
2. Compressor operating frequency will resume to normal when outdoor air temperature decrease to 37.8°C.
8.2.16. Anti-Freezing Control
This type of control is applicable on Cooling Mode and Soft Dry Mode operation only.
1. When indoor heat exchanger temperature is lower than 2°C continuously for six minutes, compressor will stop operating.
2. Compressor will resume its operation three minutes after the indoor heat exchanger is higher than 10°C.
3. At the same time, indoor fan speed increase its frequency as value of two steps up in Fan Speed Number compared to its
normal operation. (Refer Table on Fan Speed Level and Supplied Voltage).
4. If indoor heat exchanger temperature is higher than 10°C for five minutes, the fan speed will return to its normal operation.
8.2.17. Anti-Fog Discharge Control
This type of control is applicable on Cooling Mode and Soft Dry Mode operation only.
1. When indoor fan speed is set at Me- or slower, the compressor operating frequency is regulated by operation time to prevent
fog discharged from indoor as shown in below table.
Operation time, T (min) E9BKP E12BKP
0<T 30 33 Hz 44 Hz
30 < T 90 26 Hz 36 Hz
90 < T 420 26 Hz 36 Hz
2. After 420 minutes, the operation restarts again from the beginning.
3. The operation will restart the above control whenever remote controller setting temperature or fan speed setting is changed.
