2. DC Peak Current Control
• When the electric circuit to the IPM (power transistor) exceeds the set value, DC 27 ± 4A, the compressor stops. The
compressor restarts after 3 minutes.
• If within 30 seconds the set value is exceeded 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.
e. Compressor Overheating Prevention Control
• When the temperature of compressor rises to 105°C, the frequency is reduced as shown in diagram below.
When the temperature rises to 115°C or above, the compressor stops. The compressor will start operating at low frequency
when the temperature falls to 115°C and resume to normal condition when the temperature falls to 94°C.
• The compressor stops when the temperature rises to 115°C. If this condition occurs 4 times within 20 minutes, all indoor and
outdoor relays will be turned off; TIMER LED will blink and F97 is displayed.
f. Low Pressure Control (Gas Leakage Detection)
• When the following conditions as shown in the below table occur, the compressor stops and restarts after 3 minutes. If this
phenomenon is continuously occuring twice within 30 minutes, all indoor and outdoor relays will be turned off; TIMER LED
will blink and F91 is displayed.
