1.8. Compressor overheat prevention control
If the temperature of the compressor exceeds the compressor over-
heat prevention temperature (110
°
C), the operation frequency is
decreased by about 4 to 10 Hz. Then, this operation is repeated every
60 seconds until the temperature of the compressor drops below the
overheat protection temperature (100
°
C).
Once the temperature of the compressor drops below the overheat
protection temperature, the operating frequency is increased by about
4 to 10 Hz every 60 seconds until the normal operation condition
resumes.
If the temperature of the compressor exceeds the overheat protection
temperature (for 120 seconds in cooling operation or 60 seconds in
heating operation) at minimum operating frequency, the compressor
stops operating and then restarts after about 180 seconds, and the
above mentioned control is repeated.
1.9. Startup control
When the air conditioner starts in the cooling or heating mode, if the
room temperature is 2
°
C higher than the set temperature (in cooling
operation) or 3.5
°
C lower (in heating operation), the air conditioner
operates with the operating frequency at maximum. Then, when the
set temperature is reached, the air conditioner operates at the operat-
ing frequency determined by fuzzy logic calculation, then enters the
normal control mode after a while.
1.10. Peak control
If the current flowing in the air conditioner exceeds the peak control
current (see the table below), the operation frequency is decreased
until the current value drops below the peak control current regardless
of the frequency control demand issued from the indoor unit based on
the room temperature.
1.11. AUTOMATIC AIR CONDITIONING
In the AUTO mode, the temperature setting and mode are automati-
cally selected according to the room temperature and outdoor temper-
ature when the unit is turned on.
During operation, if the outdoor temperature changes, the temperature
settings will automatically slide as shown in the chart.
1.12. Airflow control
CAUTION:
Never attempt to adjust the louvres manually.
•
Manual adjustment on the louvres can cause the unit to malfunction.
Position in the COOL or DRY mode for an extended period of time,
•
When the vertical airflow louvre is positioned at the lowest
condensation may result.
1.12.1 COANDA Airflow
Press the COANDA AIRFLOW button during cooling or dry operation
when you do not want to feel cold air.
Vertical airflow louvre is set obliquely upward to deliver cool air to the
ceiling.
Press the button during heating operation. Vertical airflow louvre is set
downward to deliver the warm air down to the floor and warm you.
During operation, press the COANDA AIRFLOW button.
TO CANCEL
Press the COANDA AIRFLOW button again.
NOTE:
•
The COANDA AIRFLOW setting is cancelled
When you press Full power button while COANDA AIRFLOW is set.
•
If you want COANDA AIRFLOW operation in Full power mode,
press COANDA AIRFLOW button during Full power operation.
1.13. Difference of operation in Auto and Manual modes
In the Auto mode, the temperature setting is automatically determined based on the outside air temperature. In addition, the air conditioner operation
differs from the operation in the Manual mode as explained below.
