Features & Benefits

Swirl Swing
- It is the function for comfort cooling/heating operation.
- The diagonal two louvers are opened the
more larger than the other louvers.
After one minute, it is opposite.
Space Control
Vanes angle can be controlled by pair, considering its
installation environment.
- For example direct drafts can be annoying, leading
to discomfort and reduced productivity vane control
helps to eliminate this problem.
- Easily controlled by wired remote control.
- Air Flow can be controlled easily regarding any
space environment.
Auto Restart Operation :
- Whenever there is electricity failure to the unit, and after resumption of the power, unit will start in the same
mode prior to the power failure. Memorized condition are on / off condition, operating mode (cooling/heating),
set temperature and fan speed.The unit will memorize the above conditions and start with same memorized
condition.
Two Thermistor Control :
- There may be a significant difference between the temperature taken at the installed product and indoor tem-
perature. Two thermistor control provides option to control temperature by referring any of the two tempera-
tures. With the help of the slide switch at the back of the LCD wired remote controller, selection of the desired
thermistor for controlling the unit can be done. One thermistor is in the Indoor unit & the other one is in the
LCD wired remote.

Features & Benefits
High Ceiling Operation
- According to the height of ceiling installation, it pro-
vides variability of indoor fan motor rpm. If the height
of installation is low then you can adjust low rpm of
indoor fan motor. On the other hand if the height of
the installation is high you can adjust high rpm of
indoor fan motor. Selection of speed can be done by
slide switch at the back of the LCD wired remote.
ex:
Water Drain Pump :
- In some of the places natural drainage is not possi-
ble. For such places drain pump is very useful. It
removes condensed water from the unit.
Time Delay Safety Function :
- It delays restarting of the compressor by three min-
utes thereby preventing damage to the compressor.
Zero Standby Power:
- Due to SMPS (Switching Modulation Power Supply)
technology, there is almost zero power consumption
in the standby mode.
Child Lock Function:
-It prevents the children or others from tampering the
control buttons. Unit can be controlled by the wireless
remote controller. This can be easily set by pressing
timer key & Min key simultaneously. After child lock is
set, pressing any key will displaye CL on the LCD for
3 seconds and all the keys will be ineffective.
