1 Features
IndoorUnits IndoorUnits SplitSkyAir FTXS-GR-410A • ECONO mode decreases power consumption so that other
appliances that need large power supply can be used
• Night set mode saves energy by preventing overcooling or
overheating during night time
• Powerful mode can be selected for rapid cooling or heating
• Whisper quiet operation: down to 22dBA sound pressure level (Only
for FTXS 20,25,35,42,50G)
• Indoor / outdoor unit silent operation: "Silent" buttons on the remote
control lower the operation sound of the indoor and/or outdoor unit by
3dBA
• Night quiet mode automatically reduces the operation sound of the
outdoor unit by 3dBA during nighttime (multi outdoors in cooling
mode only) (Only for FTXS 20,25,35,42,50G)
• 3D air flow combines vertical and horizontal auto-swing to circulate a
stream of warm/cool air right to the corners of even large spaces
• 2 area intelligent eye: air flow is sent to the area in a room where no
person is detected
• Energy saving during stand by mode: reduction of energy from 10W
to 2W
• Weekly timer: allows to program the unit on a weekly basis
• Comfort mode reassures draught free operation
• Powerful mode can be selected for rapid cooling or heating
• Titanium apatite photocatalytic air purification filter absorbs
microscopic particles, decomposes odours and even deactivates
bacteria and viruses
5 steps optional
(integrated
titanium apatite)
