12.5.3. 7 Minutes Time Save Control
• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between the
compressor ON temperature (A) and compressor OFF temperature (B) during the period.
• This phenomenon is to reduce the built up humidity inside a room.
12.5.4. 60 Seconds Forced Operation
• Once the air conditioner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intake air
temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at the
remote control is permitted.
• The reason for the compressor to force operate at minimum 60 seconds is to allow the refrigerant oil run in a full cycle and return
back to the outdoor unit.
12.5.5. Starting current Control
• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start to
operate at 1.6 second later.
• The reason of the difference is to reduce the starting current flow.
12.5.6. Freeze Preventive Control
• To protect indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid form return to compressor.
• This control will activate when the temperature of indoor heat exchanger falls below 2°C continuously for more than 4 minutes.
• The current fan speed will change to freeze prevention speed after 70 seconds compressor on. When indoor pipe temperature
reaches certain temperature for 5 sec. the speed will be increased as in below figure.
• Compressor will turn off when indoor temperature falls below 2°C for more than 4 minutes. It will restart again when indoor heat
exchanger temperature rises to 10°C.
• Restart control (Time Delay Safety Control) will be applied in this control.
