14. Protection Control
14.1 Protection Control For All Operations
14.1.1 Restart Control (Time Delay Safety Control)
š
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.
š
This control is not applicable if the power supply is cut off and on again.
š
This phenomenon is to balance the pressure inside the refrigerant cycle.
14.1.2 Total Running Current Control
š
When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor
operation will be decreased.
š
If the running current does not exceed X value for 5 seconds, the frequency instructed will be increased.
š
However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for
3 minutes.

The first 30 minutes of cooling operation, (A) will be applied.
14.1.3 IPM (Power transistor) Prevention Control
š
Overheating Prevention Control
o
When the IPM temperature rises to 120°C, compressor operation will stop immediately.
o
Compressor operation restarts after 3 minutes the temperature decreases to 110°C.
o
If this condition repeats continuously 4 times within 20 minutes, timer LED will be blinking (“F96” is indicated).
š
DC Peak Current Control
o
When electric current to IPM exceeds set value of 18.5 A (E7 ~ 15NK) and 30.0 ± 5.0A (E18NK), the
compressor will stop operate. Then, operation will restart after 3 minutes.
o
If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will
restart after 1 minute.
o
If the set value exceeded again within 30 seconds after the compressor starts, the operation will restart after
1 minute. 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).
