g. Minimum Frequency Operation Protection
• When the compressor operates at less than 31 Hz for 40 minutes, the operating frequency will increase to 31 Hz for 2
minutes.
h. Low Frequency Operation Protection
Indoor intake air temp. (°C)
Outdoor air temp. (°C)
Indoor heat exchanger temp. (°C)
Operation
• When the above conditions occur, the compressor will operate at minimum frequency as below:-
Cooling/Soft Dry
Heating
i. Low Power Supply Voltage Protection
• When the DC voltage supplied to IPM (Power transistor) is reduced to 169 ± 5V (CS-G95KE) or 160 ± 5V (CS-G125KE) the
compressor stops and restarts after 3 minutes.
• If within 30 seconds after restarting of compressor, the DC voltage is reduced to 169 ± 5V (CS-G95KE) or 160 ± 5V (CS-
G125KE) again, the compressor will stop for 1 minute.
If this condition repeats for 7 times, all indoor and outdoor relays will be turned off; TIMER LED will blink and F99 is
displayed.
j. High Power Supply Voltage Protection
• When the voltage supply (AC) exceeds 295 ± 15V (T
supply (AC) is below (T - 5)V. However, waiting for 3 minutes is necessary for re-operation.
