2.3. Heat operation
The compressor turns on or off, at State 2, turns on continuously at
State 1 & 3.
3. FAN SPEED
Fan speeds are given by the indoor fan motor, "DL"~"HH" which are
available in the following operation mode.
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 ",compres-
sor is not turned on. Only the inddor fan motpr is turned on 8 minutes
later for 3 minutes.
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 temper-
ature 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 tempera-
ture to prevent the overloading of the compressor and restrain the rise
in high pressure.
When the indoor pipe temperature exceeds U1digC, the outdoor fan
motor is turned off, and when the indoor pipe temperature falls
U2digC, the outdoor fan motor turns on.
