Take control of your environment

  • Temperature

    With sensitive built-in sensors, the Milieu Climate Smart Thermostat monitors your home’s temperature and automatically adjusts the air conditioning system to maintain your ideal indoor climate and level of comfort within your home at all times.

  • Humidity

    By detecting the amount of moisture in the air, Milieu Climate monitors the humidity in your home and displays how to restore the ideal level. When low, you can turn on your humidifier and when high, you can activate your air-conditioning system’s dry mode.

  • Air Quality

    A high concentration of Volatile Organic Compounds (VOCs) in your home can have an impact on your health. The Milieu Climate Smart Thermostat effectively monitors your home’s air quality with an innovative VOC sensor to help keep you and your family safe.

  • 24h Timer

    With the Milieu Climate Smart Thermostat timer function, you can say goodnight with the perfect home climate, knowing that your system will switch off once you and your family are fast asleep. It’s complete peace of mind at night.

  • 7-Day Schedule

    Program your weekly routine and always come home to the perfect environment every day with the Milieu Climate’s 7-day scheduler function. With your Smart Thermostat, you’ll never have to worry about your home’s temperature again.

  • Away mode

    With the innovative Away mode, the Milieu Climate Smart Thermostat will ensure that the temperature in your home doesn’t get too hot or cold while you are away, making it faster and easier to reach your ideal temperature when you return.

  • Auto mode

    The Milieu Climate’s Auto mode function helps you save on energy and maximise convenience by allowing you to set your ideal temperature range for your home – meaning the Cooling and Heating systems are not required to operate constantly.

  • Dry mode

    When the Milieu Climate’s built-in sensors detect and display high humidity levels in your home, you can activate the Dry mode function of your air conditioning system to remove excess moisture and humidity from the air, keeping you and your family comfortable.

  • Fan options

    If your Air Conditioning system uses Milieu Fan logic, the Auto-i feature will automatically turn your fan on if the air becomes too toxic, and the Circulate feature will activate the fan from time to time to help save energy and keep your home comfortable and healthy.

  • Sound

    With the Milieu Climate Smart Thermostat, you can actively monitor the sound levels in your home or office to ensure optimal relaxation and concentration. You can even monitor for loud noises while you’re not home via the Milieu Climate App.

  • Light

    The Milieu Climate Smart Thermostat is the perfect device for monitoring the ideal level of light comfort in your home, no matter the time of day. It displays the brightness and can even detect when lights have been left on, helping you save on your energy bills.

  • Pressure

    Featuring a highly accurate barometric sensor, the Milieu Climate Smart Thermostat can monitor the atmosphere around your home to keep you informed and prepared for any upcoming changes in weather conditions.
