Low input rotary compressor with high efficiency is equipped.
All operation modes can be operated from distance place by the wireless remote
control. And also liquid crystal is used to show all kinds of operation or, off, air
flow switch, operation switch, timer switch, timer set, temperature set, flap control
Defumidifies while keeping room temperature to the thermostat setting level by
M. C. thermostat.
ON timer setting for anytime during 12 hours can be performed.
When OFF-TIMER operation is selected, the room temperature is automatically
controlled after a while, ensuring that the room is not too cold during cooling.
• During COOL and DRY: the pre-set temperature is raised by 0.5˚C at the start
of OFF-TIMER operation (when the timer is set). After that, the temperature
goes up by 0.5˚C every 30 minutes to become 1.5˚C higher within one hour.
Room unit air volume can be automatically controlled step by step, according to
the difference between room temperature and setting temperature.
1. Shorten pull down time for cooling operation.
2. Low noise level operation can performed by proper air volume.
M. C. thermostat improves on energy saving and comfort, by control-
ling room temperature with high accuracy.
The flap can be automatically controlled by operating wireless remote control.
• AUTO (Natural flow)
: Flap operation is automatically controlled.
• Swing : This will swing the flap up and down.
• Memory flap : Once the flap position is set, the unit memorizes
the position and continues to operate at the same
position from the next time.
The room temperature is checked 60 minutes before the timer is at ON. De-
pending on the temperature at that time, the operation starets 5 to 60 minutes
before the timer is at ON.
We are constantly trying to do better service to our customers by installing such
judges that show abnormality of each function as follows:
• Abnormality of heat exchanger thermistor:
RUN lamp flashing
• Abnormality of room temperature thermistor:
RUN lamp flashing
• Abnormality of indoor fan motor:
RUN lamp flashing.
