Features (click on the features to know more)

  • TechnologyPowerful Mode

    The air circulation speed and the set temperature changes automatically to cool the room quickly for a period of 30 minutes. The fan speed is on super high in this mode.

  • TechnologySupercool Function

    In this, the AC works at its maximum, so as to maximise cooling. This function is available in auto & cool mode.

  • TechnologyFilter Clean Indicator


    At the time of cleaning process a white color LED called auto clean indicator on IDU will show ‘ON’ continuously

  • TechnologyOn/Off Timer With Advanced Start-Up

    Simple On/Off Timer : You set the timer to switch on the AC at the specified time. The AC automatically starts at the preset time, and begins to cool the room. However, when you reach the room, it might be a bit too warm or a bit too cool. Basically, you don't get the desired comfort level. Also, you end up wasting a lot of electricity.

    On/Off Timer With Advanced Start-up: You set the temperature that you want at the given time. The AC is smart enough to scan the room an hour before the set time. It calculates the time it'll need to reach the desired temperature, and switches on accordingly. So you get the perfect comfort level as soon as you come back, without wasting any electricity.

  • TechnologyDigilock

    Is your AC being misused in your absence? If yes, just switch to the Digilock. It locks your AC and prevents the misuse in your absence, besides ensuring that your comfort settings aren't affected by tampering or accidental pressing of keys.

  • TechnologyAuto Climate Technology

    Human comfort is a combination of many factors, as depicted on the right. For example, in Delhi, the month of June is the peak of summers and temperatures touch close to 44ËšC with a humidity level of 60%. Whereas in Mumbai, at the same time of the day and the month, the temperature is around 35ËšC with a humidity level of 85%.

    In a regular AC, you can control these factors by changing the temperature and regulating the fan speed. But this presents you with more than 50 different combinations and choosing the correct option for optimal efficiency and comfort becomes extremely cumbersome.

    That's why we developed Auto Climate Technology (ACT) which is a super-advanced intelligent feature that has temperature and humidity data of over 100 cities fed into it. The AC recognises which city you are in, the time of day and your individual metabolic needs (to be chosen by you). Based on these factors, it continuously changes the settings of the AC to provide you the most comfortable environment, while functioning most efficiently, at the touch of a button.

  • TechnologyPrecoated Aluminium Fins

    Prevents the air conditioner from rusting or corrosion even in the harshest weather conditions.

  • TechnologyAuto Fan Speed

    The fan speed is automatically adjusted for comfort, depending on the running state of your air-conditioner, i.e., if the compressor is cut off, the fan speed automatically comes down to low level and vice- versa. Similarly, once the set temperature is achieved, the fan speed comes down to a low level to optimise your comfort level.

  • Technology43 Quality Tests
  • TechnologyWireless LCD Remocon

    It comes with an LCD display for extra clarity. Also, when not inuse, the display shuts off automatically ensuring a longer battery life.

  • TechnologyAuto Power Save Mode

    The device will automatically select the comfort temperature and will maintain the temperature at about 25Ëš C with suitable fan speed.

  • TechnologyLow Derating (10% Higher Performance in Peak Summer)
  • TechnologyRefrigerant-R22
