The Daikin FXZQ20M9 four-way cassette unit is characterized by:

• the possibility of reducing the noise level of outdoor units by 9 dB at night (reducing energy consumption)
• the ability to work in the event of failure of one of the compressors
• Automatic indoor unit fan speed control (low noise)
• self-diagnosis function (quick finding of possible malfunctions; reduction of time and costs for their elimination)
• high energy efficiency in both cooling and heating mode
• long life filter
• attractive appearance
• the possibility of fixing the air damper (5 positions; controlled by an infrared remote control; swing angle from 0 to 60 °)
• automatic mode selection function
• increased system reliability
• quiet operation of the unit (noise level 25dBA)
• the ability to automatically restart the system (in case of a temporary power failure)
• the ability to supply air flow simultaneously in two, three or four directions
• confirmation of the quality assurance of DAIKIN equipment by all regulatory documents of European climate organizations)
• compact design
• automatic synchronous swing of horizontal dampers (optimal air circulation throughout the room)
• the most efficient and ozone-friendly refrigerant R-410A
• the largest number of indoor units in one system
• design for high ceilings (air circulation efficiency in rooms with a ceiling height of up to 4.2m)
• "No one at home" function (energy saving without compromising comfort)
• possibility of application in cold regions (lower limit of atmospheric temperature when operating in heating mode -25°С)
• energy saving technology (reducing power consumption)
• the possibility of admixing atmospheric air (increasing the oxygen content in the room air)
• ease of maintenance (direct access to structural elements after removing the decorative panel)
• variety of control panels (convenience of remote control)
• timer operation (automatic coordination of the air conditioner with the daily schedule of life)
• authorized service (maintenance of the air conditioner during and after the 3-year factory warranty)
• double temperature control function (selection of the nature of the change in the air temperature in the room using a temperature sensor)
• the ability to automatically restart the system (in case of a temporary power failure)
• modern control and monitoring system (indication of the value of any parameter; automation of most functions)
• longest refrigerant piping (up to 1000 m)
• ceiling pollution prevention
• Possibility of automatic refueling of the system with refrigerant with automatic determination of the amount of refrigerant to be charged
• using the unit for small or well insulated rooms
• modular layout of outdoor units
• program air drying (automatic maintenance of relative humidity in the room from 35 to 60% without changing the temperature)
• one touch control function
• the ability to limit the power consumption (in conditions of lack of electricity)
• inverter capacity control
• forced condensate drain (drainage pump - condensate lift to a height of 750 mm - included as standard)
