5813. Protection Control13.1 Protection Control for All Operations13.1.1 Restart Control (Time Delay Safety Control) The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned onagain by pressing OFF/ON button at remote control within this period. This control is not applicable if the power supply is cut off and on again. This phenomenon is to balance the pressure inside the refrigerant cycle.13.1.2 Total Running Current Control1 When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressoroperation will be decreased.2 If the running current does not exceed X value for 5 seconds, the frequency instructed will be increased.3 However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for3 minutes.Operation Mode CU-RE18PKR CU-RE24PKR CU-RE28PKRA 10.07 12.48 14.86B 8.82 11.46 13.86Cooling/Soft Dry (X)C 8.05 10.12 13.86Heating (X) 11.03 13.54 16.51Y 15.00 19.00 19.004 The first 30 minutes of cooling operation, (A) will be applied.13.1.3 IPM (Power Transistor) Prevention ControlA. Overheating Prevention Control (for RE18PKR, RE24PKR only)1 When the IPM temperature rises to 120°C (RE18PKR, RE24PKR), compressor operation will stopimmediately.2 Compressor operation restarts after 3 minutes the temperature decreases to 110°C (RE18PKR, RE24PKR).3 If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).B. DC Peak Current Control1 When electric current to IPM exceeds set value of 30.0 ± 5.0A, the compressor will stop operate. Then,operation will restart after 3 minutes.2 If the set value is exceeded again more than 30 seconds after the compressor starts, the operation willrestart after 1 minute.3 If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after1 minute. If this condition repeats continuously for 7 times, all indoor and outdoor relays will be cut off, timerLED will be blinking (“F99” is indicated).
