    Overview

    24-hour Timer

    If you want to fall asleep to the coolness that this air conditioner provides, but don’t want the unit running all night, the 24-hour timer will allow you to run this unit to specific time frames that you pre-program.

    Stay comfortable no matter the weather

    As a reverse cycle air conditioner this appliance can cool your room in summer or heat it in winter. Its dehumidifier mode can also extract moisture from the air during sticky or misty weather while the Fan mode can create a relaxing and gentle indoor breeze.

    Rest easy

    One popular feature of this air conditioner is the Sleep mode designed to help you rest more comfortably by changing the temperature gradually over time. Plus it helps to prevent the air conditioner from overcooling your bedroom while you're asleep.

    Pick up right where you left off

    Thanks to the auto restart function in this unit – if ever there is a sudden power failure, the system memorises the exact settings you’d had set, so when the power comes back online you can pick up where right you’d left off.

    Great for cooling, not good for the bedroom
    Don't buy this unit for your bedroom unless you want a permanent night light included too! It has a large bright LED light on the front of the unit that cannot be switched off. I tried covering it with tape, the light still shines out the top of the unit! I spoke to Dimplex and it's a known complaint but they're still being sold without that being noted. If I had have known I would not have bought this unit for my bedroom. Otherwise it's a very easy unit to use, quiet and very cold!

    Excellent AirConditioner, does the trick nicely.
    I purchased this not long ago and it is excellent in cooling room down quickly. Probably the only small setback is that the “ON” light is quite bright and does illuminate the room, but a piece of paper strategically placed over it solved my problem anyway. Happy customer!
