Plasma Air Purifying System
The PLASMA Air Purifying Function not only removes micro-
scopic contaminants and dust, but also removes house
mites, pollen, and pet fur helps to prevent allergic diseases
like asthma.
High Head Drain Pump(700mm)
Built-in Drain Pump drains out water automatically.
A standard drain-head height of up to 700 mm is possible, creating the ideal solution for perfect water drainage.
High-Ceiling Corresponding Operation
According to the height of the installation, it provides vari-
ability 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.
Tele Control (Accessory)
- It provides you ease of control. Air conditioner
can be switched on/off by the telephone. It
saves time & energy.

Weekly Program
- On/Off schedule of operation for a period of ONE
week.
No need to turn the unit On/OFF manually during
working days. On/Off time is scheduled in micom of
the wired remote control.
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.
Group Control
- It enables to control as much as 16 units with the
help of one wired remote controller. All the units will
follow same setting of temperature & other sub func-
tions.
Central Control(Accessory)
- It enables to control 16 x 8 = 128 units with the help
of 8 controllers. All units can be put on and off from
one Central Room.For Setting Temperature, Fan
Speed and other sub functions, access the respec-
tive LCD wired remote controller of each unit.
❈Sub PI485(with wire assembly) should be pur-
chased as optional.
