15.8 Deice Control
When outdoor pipe temperature and outdoor air temperature is low, deice operation starts where indoor fan
motor and outdoor fan motor stop, indoor unit horizontal vane close and operation LED blink with compressor ON.
15.9 Time Delay Safety Control (Restart Control)
The compressor will not restart within three minutes after compressor is stopped.
This control is not applicable if the power supply reset or after deice condition.
15.10 30 seconds Force Operation
Once the compressor starts operation, it will not stop its operation for 30 seconds in order to cycle back
compressor oil.
However, it can be stopped using remote control or Auto OFF/ON button at indoor unit.
15.11 Total Current Control
By referring to table below, during normal (default) operation, the running current refer to Hi values and during
Power Save Mode, the running current refer to Lo values. (not applicable for 2E18/2E15)
When the outdoor unit total running current (AC) exceeds X value, compressor frequency will decrease.
If the running current does not exceed X value for 5 seconds, compressor frequency will increase.
However, if total outdoor unit running current exceeds Y value, compressor will be stopped immediately for
3 minutes.

15.12 IPM (power transistor) Protection Control
Overheating Prevention Control
o
If IPM temperature rises to 80°C, outdoor fan speed will be increased.
o
When the IPM temperature rises to 95°C, compressor operation will stop immediately.
o
Compressor operation restarts when temperature decreases to 90°C.
o
If IPM temperature detected less than -30°C, IPM is judged as open circuit (“F96” is indicated).
DC peak current control
o
When IPM DC current exceeds set value of 30.0 ± 3.0 A, the compressor will stop.
o
If the DC peak current detected within 30 seconds after operation starts, compressor will restart after
1 minute.
o
If the DC peak current detected 30 seconds or more after operation starts, compressor will restart after
2 minutes.
o
Within 30 seconds after compressor restarts, if the DC peak current is exceeded set value continuously for
7 times, all indoor and outdoor relays will be cut off (“F99” is indicated).
Error reset can be done by power supply reset.
