1 Features
IndoorUnit SplitSky FBQ-C7VEB R-410a • Reduction in power consumption thanks to DC inverter fans
• Improved comfort thanks to 3-step airflow control
• Maximum external static pressure (ESP) is 100Pa
• Possibility to change ESP through wired remote control allows
optimisation of the supply air volume
• Blends unobtrusively with any interior décor: only the suction and
discharge grilles are visible
• Energy efficient: up to class A energy labels
• Home leave operation saves energy during absence
• Whisper quiet operation: down to 26 dBA sound pressure level
• Standard air filter: removes airborne dust particles to ensure a steady
supply of clean air
• Easy installation thanks to automatic air flow adjustment towards
nominal air flow rate
• Built-in drain pump as standard increases reliability of the drain
system
