Lightera non-inverter air conditioners from Haier are designed to create a comfortable atmosphere in homes and offices up to 70 m2. The O2 Fresh plug-in maintains the required level of oxygen in the room, the Nano-Aqua generator humidifies the air, and the reduced noise modes "Comfort sleep" and Super Quiet ensure quiet operation of the air conditioner.

Optional: O2 Fresh - fresh air supply. An innovative system for supplying fresh air to the room allows you to maintain the necessary balance of oxygen. The O2 Fresh module is installed on or near the outdoor unit. Thus, the influence of fresh air influx on heat exchange processes is eliminated. Power comes from the board of the indoor unit, and control is carried out from the remote control. Ultraviolet lamp. The UV lamp built into the indoor unit generates ultraviolet rays with a wavelength of 254 nm. The function of UV protection involves exposure to microorganisms, bacteria and viruses in the room. Carbon filter. Activated carbon effectively removes benzene, radon, total volatile organic compounds and other substances hazardous to human health from the air. Antibacterial filter 3 in 1: antibacterial, antiviral and antiallergic filter. Detains and deactivates dust mites, pollen, viruses and bacteria. Ag+ heat exchanger coating. The evaporator of the indoor unit is covered with silver ions, which prevent the growth and reproduction of bacteria. Nano-Aqua generator ionizes water molecules, splitting them into hydrogen ions (H+) and oxygen (O2-), which combine into hydroxide-radials (OH) or hydrogen peroxide (H2O2), destroying bacteria by changing their molecular structure. The Nano-Aqua generator forms water microparticles that are easily absorbed by human skin, keeping it moist. Comfortable sleep - the mode of operation of the air conditioner, providing the most comfortable temperature for sleeping: in cooling mode, the temperature will rise twice by 1 degree and maintain this mode for 6 hours, and in heating mode it will drop twice by 2 degrees, and then rise by 1 degree for comfortable awakening. The duration of the regime is 8 hours. Volumetric air flow - the air jet is designed to be directed in several directions in order to avoid directing the air flow to the people in the room. Maximum Air Throw - The innovative fan design allows you to supply cooled or heated air up to 12 meters away, avoiding drafts, hypothermia or overheating of people near the operating air conditioner. Intelligent Air mode - air flow distribution depending on its temperature: hot air is supplied almost vertically downwards, and cold air flow is directed along the ceiling plane. Intensive Turbo/Power mode - high-speed fan operation mode that allows you to quickly reach the set temperature. Optional: Wi-Fi - air conditioning control system from a smartphone. Allows you to work according to the “smart home” scheme, set operating modes, turn the air conditioner on and off remotely. For example, to warm up or cool down the house before arriving from work, to maintain an economical “heating standby” mode during the holidays, etc. Customizable automatic mode - the air conditioner will automatically maintain the set temperature in the house, using the "heating", "cooling" modes, as well as changing the fan speed and compressor power. Auto-restart - in the event of a power failure, the air conditioner settings are saved, and after power is supplied, the air conditioner will automatically return to the preset operating mode. Compressor Protection - To protect the compressor from damage caused by frequent starts, a three-minute start delay is provided. In this way, intelligent technology is protected in the event of a power failure. 24-timer - the ability to set the exact time to turn on and turn off the air conditioner in advance. Intelligent defrosting - defrosting only when needed, significantly reducing energy costs. Self-diagnosis - in case of malfunction or error in the operation of the air conditioner, primary diagnostics are carried out, and the code of the received error or malfunction is displayed on the display. This allows you to reduce the cost of service and repair of the air conditioner. Anti-corrosion protection Blue Fin - a special cobalt blue epoxy coating that prevents corrosion of metal elements of the outdoor unit due to dust, salt, moisture, etc. Wide voltage range - for normal, stable operation of air conditioners, a voltage range from 150 to 264 V can be used. 5 speeds of the internal block fan – the fan of the internal block can work in 5 high-speed modes, for providing different processes and operating modes. The internal block fixation – the indoor unit is equipped with a special fixation system, which will not allow to fix the unit crookedly. 2 piping sides - drain and freon pipes can be connected either on the left or on the right. Easy to clean - the front panel of the air conditioner is easy to clean and the louvres are easy to remove without the need for special tools. Long PCB life – Haier Air Conditioner PCB manufacturing technology meets all system requirements. Thus, their service life has been significantly increased. Hidden LED display - in the off state, the display is completely invisible on the surface of the indoor unit.
