Hot-Keep
This function automatically controls the on-off
operation of the indoor fan motor in accordance
during the heating operation, thereby preventing
the air conditioner from delivering a cold air when
the compressor is off.
When the room temperature exceeds the
thermostat line “H1”, the compressor is turned off,
and the indoor fan motor is turned off after
rotating at “HUL” for 30 seconds. 3 minutes and
10 seconds after turning off the compressor, the
indoor fan motor is turned on for 3 minutes and 20
seconds. At 10 seconds after turning on the
compressor, the indoor fan motor is turned on.
The next compressor OFF time is for 3, 8 or more
than 8 minutes according to the room temperature
(the time increases with a rise of room
temperature) when 3 minutes elapse after turning
on the compessor.

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”.

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.
