4. Hot-Keep
This function automatically controls the on-off operation
of the indoor fan motor in accordance with the ON-OFF
operation of the compressor during the heating
operation, thereby preventing the air conditioner from
delivering a cold air when the compressor is off.When
the room temperature enters area “ D “, the compressor
is turned off, and the indoor fan motor is turned off after
rotating at “HUL” for 30 seconds. 3 minutes after turning
on the compressor, the compressor is turned on for 3
minutes. At 10 seconds after turning on the compressor,
the indoor fan motor is turned on. The next compressor
OFF time is accordance with the room temperature
area when 3 minutes elapse after turning on the
compessor. If the area “D “, compressor OFF time is for
3 minutes and if “ E “, it’s for 8 minutes. If the area “ F
“,compressor is not turned on. Only the inddor fan motpr

5. Preheat air flow
This function is intended to prevent cold air from
being discharged when the heating operation
starts or when defrosting. When the indoor pipe
temperature is below 29˚C at the begining of the heat
operation or after defrosting, the indoor fan motor stays.
When the indoor pipe temperature gets higher than
29˚C, the fan motor is turned on at speed “HUL” after
compensation of starting. When the indoor pipe
temperature exceeds 35˚C, the specified fan speed is
restored. When the indoor pipe temperature falls below
30˚C, the fan speed shifts down to "HUL". And, when
the indoor pipe temperature falls below 23˚C, the fan
motor turns off. Then, over 29˚C , it turns on again at
speed “HUL”.

6. Overheating protection system
When overloading occurs during the heating operation,
this system controls the outdoor fan motor according to
the indoor pipe temperature to prevent the overloading
of the compressor and restrain the rise in high pressure.
When the indoor pipe temperature exceeds U1˚C, the
outdoor fan motor is turned off, and when the indoor
pipe temperature falls U2˚C, the outdoor fan motor
turns on.
