10.2. Protection Control
10.2.1. Time Delay Safety Control
•
Compressor will not start for three minutes after stop of the operation.
10.2.2. 30 Seconds Forced Operation
•
Once compressor starts the operation, it will not stop its operation for 30 seconds. However, it can be stopped with the remote
controller or the Auto button on the indoor unit.
10.2.3. 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 five seconds, the frequency instructed will be increased.
3. However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for three minutes.

Operation Mode X (A) Y (A) X (A) Y (A)
Cooling/Soft Dry (A) 11.0 15.0 8.8 15.0
Cooling/Soft Dry (B) 9.6 15.0 7.7 15.0
Heating 11.5 17.0 10.8 17.0
4. The first 30 minutes of cooling operation, (A) will be applied.
10.2.4. IPM (Power transistor) Protection Control (DC Peak detection)
Abnormal Current Control
•
If inverter load current (DC peak) exceeds a rated value, compressor will be stopped immediately. When the excess occurs
within 30 seconds after operation, it restarts in 1 minute and when after 30 seconds, restarts in 2 minutes.
•
If the excess continuously occurs 7 times within 30 minutes after compressor starts, the unit will be stopped and timer LED on
the indoor unit will be blinking. (“F99” is to be confirmed.)
IPM Overheating Prevention Control
•
If temperature of IPM exceeds 217°F, compressor will be stopped. It will restart in 2 minutes. Temperature for restarting: 194°F.
•
If the excess occurs 4 times within 30 minutes after compressor starts, the compressor will be stopped and timer LED on the
indoor unit will be blinking. (“F96” is to be confirmed.)
10.2.5. Compressor Overheating Prevention Control
1. If discharge pipe temperature exceeds 212°F, compressor power will be limited.
2. If discharge pipe temperature exceeds 233°F, compressor will be stopped.
3. If the above excess occurs 4 times per 10 minutes, timer LED will be blinking. (“F97” is to be confirmed.)
10.2.6. Outdoor High Pressure Prevention Control (Cooling and Soft Dry Operations)
1. If outdoor heat exchanger temperature exceeds 145°F in cooling or soft dry operation, compressor will be stopped.
2. Timer LED is not blinking. (“F95” is memorized, then.)
