8.2. Protection
a. Time Delay Safety Control
•
The Compressor is not restarted for 3 minutes after stop of compressor.
b. 30 Second Forced Operation
•
Once the compressor is ON, it will not turn OFF for 30 seconds. However, it is turned off by remote control or Automatic
switch.
c. Total Running Current Control
•
When the outdoor unit total running current (AC) exceeds I1, the frequency is lowered by 1 rank. If I1 is not exceeded for
30 seconds, the frequency is highered by 1 rank at one time. If the outdoor unit total running current exceeds I2, the
compressor is immediately stopped for 3 minutes.

•
If the outdoor unit total running current exceeds I2 3 times within 30 minutes, all indoor and outdoor relays will be turned off;
TIMER LED will blink and F98 is displayed.
d. IPM (Power transistor) Prevention Control
1. Overheating Prevention Control
•
When the IPM (power transistor) temperature rises to 100 ± 10°C, the compressor stops immediately. The compressor
is restarted when the IPM (power transistor) temperature decreases to 90 ± 10°C after 3 minutes (Time Delay Safety
Control). If this condition occurs 4 times within 40 minutes, all indoor and outdoor relays will be turned off; TIMER LED
will blink and F96 is displayed.
