FVXS-BAVMBR410A • Compact&stylish
• Lightweightand compact
• Can be used as a floor standing or lower wall application. As a floor
standing model, it can be semi-recessed or fully recessed without
loss of capacity.
• A double horizontal air outlet ensures uniform air flow and
temperature distribution
• The home leave operation saves energy during absence
• Air purification filter: deodorises the air and helps to prevent bacterial
and viral propagation
• Thephotocatalytic deodorising air filter: powerfully decomposes
cigaretteand petodours,removeshouse dustand pollenand
deactivates bacteria and viruses
• Powerful mode can be selected for rapid cooling or heating
• Washable front panel
• Indoor unit silent operation: "Silent" button on the remote control
lowerstheoperation sound of theindoor unit by3dB(A).
• Easy to install
• Up to 4 indoor units can be connected to 1 Multi outdoor unit. All
indoor unitsare individuallycontrollablewith remote control and do
not need tobe installed in the same room or at the same time. They
operate simultaneously within the same cooling operation
• Daikin remotecontrols giveyoueasy control at yourfingertips.
• The remote control has a 24-hour timer
• The indoor unit also has a start/stop button mounted on the front
panel
• Up to 5 indoor units can be operated from a single centralised control
