1 Features
IndoorUnit Split-Sk FFQ-CFullyflat Unique design in the market that integrates fully flat into the ceiling
• Fully flat integration instandard architectural ceiling tiles, leaving only
8mm
• Remarkable blend of iconic design and engineering excellence with
an elegant finish in white or a combination of silver and white
• Two optional intelligent sensors improve energy efficiency and
comfort. The presence sensor adjusts the set point if no one is
detected in the room. It also automatically directs air flow away from
any person to avoid draught. The infrared floor sensor detects the
averagefloor temperatureand ensureseven temperaturedistribution
between ceiling and floor to prevent cold feet.
• Reduced energy consumption thanks to specially developed small
tube heat exchanger, DC fan motor and drain pump
• Fresh air intake integrated in the same system thus reducing
installation cost as no additional ventilation is required
• Standard drain pump with 850mm lift increases flexibility and
installation speed
• No optional adapter needed for DIII-connection, link your unit into the
wider building management system.
