4313. 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 Current1 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.Model RE9QKE RE12QKE RE15QKEOperation Mode X (A) Y (A) X (A) Y (A) X (A) Y (A)Cooling / Soft Dry (A) 4.41 6.07 7.94Cooling / Soft Dry (B) 3.94 5.52 7.42Cooling / Soft Dry (C) 3.94 5.52 7.42Heating 4.6515.026.0015.029.1315.024 The first 30 minutes of cooling operation, (A) will be applied.13.1.3 IPM (Power transistor) Prevention Control Overheating Prevention Control1 When the IPM temperature rises to 120°C, compressor operation will stop immediately.2 Compressor operation restarts after 3 minutes the temperature decreases to 110°C.3 If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated). DC Peak Current Control1 When electric current to IPM exceeds set value of 16.0 ± 2.0A, 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 3 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).
