Configuration design types
A Fan Coil unit can be configured as a compact device or a modular installation device:

Compact devices: These are supplied with enclosures and are available as self-contained units or for
wall or ceiling mounting.

Built-in devices: These have no enclosures and are mounted in the wall, in the ceiling or in the floor.
The air is blown into the room through a grille.
Air supply
Fan Coil units are available as recirculation or as mixed air devices.

Recirculation devices: The room air is directed past heat exchangers by the fans.

Mixed air devices: The room air is mixed with fresh air. The mixing ratio between recirculated and
fresh air can usually be adjusted.
