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.
• 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
- If IPM temperature rises to 80C, outdoor fan speed will be increased.
- When the IPM temperature rises to 95C, compressor operation will stop immediately.
- Compressor operation restarts when temperature decreases to 90C.
- If IPM temperature detected less than -30C, IPM is judged as open circuit (“F96” is indicated).
• DC peak current control
- When IPM DC current exceeds set value of 30.0 ± 3.0 A, the compressor will stop.
- If the DC peak current detected within 30 seconds after operation starts, compressor will restart after 1 minute.
- If the DC peak current detected 30 seconds or more after operation starts, compressor will restart after 2 minute.
- 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.
15.13. Compressor Protection Control (Gas leak detection control 1)
• Control start conditions
- For 5 minutes, the compressor continuously operates and total current is low.
- During Cooling or Soft Dry operation:
Indoor intake temperature — indoor piping temperature is below 4C.
- During Heating operation:
Indoor pipe temperature — indoor intake temperature is below 3C.
- Not during deice control.
- Compressor ON with maximum frequency.
• Control content
- Compressor stops (and restart after 3 minutes)
- If the conditions above happen 4 times within 60 minutes, the unit will stop operation (“F91” is indicated).
