Auto 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.
Extra Heat Exchanger (XHE): Window ACs are air-cooled. While Hitachi ACs are also air-cooled, there is an Extra Heat Exchanger attached to the coil which is cooled by the condensate water. Water-cooling is more effective than air cooling. Hence, with this Extra Heat Exchanger, the ability of the machine to throw hot air outside increases as compared to only air-cooled machines. Thus enabling the AC to operate efficiently even at very high ambient temperatures.
Kaimin: Kaimin adjusts the temperature automatically through the night to suit your body needs. It is an intelligent feature that ensures you get sound sleep every night and wake up feeling fresh every morning. By raising 1 Deg C per hour for upto 4 hours, its operation ensures saving of power.
Low Derating: As the ambient temperature increases, the ability of the AC to deliver the required cooling decreases. But the heat exchanger increases the capacity even at very high temperatures ensuring the ability of the machine to deliver optimum cooling.
