1 Features
IndoorUnit SplitSky FTXS-D3VMW_D2 R-410A • Comfort mode reassures draught-free operation
• Vertical auto-swing function moves the discharge flaps up and down
for efficient air distribution throughout the room
• You have the choice out of 5 fan speeds to select
• Daikin’s special dry programme reduces humidity in the room without
variation in room temperature
• Night set mode saves energy by preventing overcooling or
overheating during night time
• Powerful mode can be selected for rapid cooling or heating
• Indoor unit silent operation: "Silent" button on the remote control
lowers the operation sound of the indoor unit by 3dB(A).
• The new titanium apatite photocatalytic air purification filter increases
the active surface area for effective purification and deodorisation
• ECONO mode decreases power consumption so that other
appliances that need large power supply can be used
• The movement sensor saves power consumption in unoccupied
rooms
• Daikin remote controls give you easy control at your fingertips.

Notes Sound values are measured in an anechoic room.
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more details,
please refer to sound level drawings of this chapter.
The sound power level is an absolute value indicating the power which a sound source generates.
