13 Protection Control
13.1. Protection Control For All Operations
13.1.1. 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 on again 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. 30 Seconds Forced Operation
• Once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation although the intake air
temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON button at the remote control
is permitted or the Auto OFF/ON button at indoor unit.
• The reason for the compressor to force operation for minimum 30 seconds is to allow the refrigerant oil run in a full cycle and
return back to the outdoor unit.
13.1.3. Total Running Current Control
1. When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation 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 for 3 minutes.
4. The first 30 minutes of cooling operation, (A) will be applied.
13.1.4. IPM (Power transistor) Prevention Control
A. Overheating Prevention Control
1. When the IPM temperature rises to 100
°
C, compressor operation will stop immediately.
2. Compressor operation restarts after 3 minutes the temperature decreases to 95
°
C.
3. If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).
B. DC Peak Current Control
1. When electric current to IPM exceeds set value of 20.2 A, 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 will restart after 1
minute.
3. If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after 2 minutes. If
this condition repeats continuously for 7 times, all indoor and outdoor relays will be cut off, timer LED will be blinking (“F99”
is indicated).
