VOLUTE
Louvres change position to distribute air according to
heating or cooling operation.
iIn cooling only mode the louvres are positioned to
distribute air outwards from the discharge, which allow
airflow close to the ceiling.
In heat pump mode the louvres are repositioned to blow
air in a downward direction. The air should flow towards
to the floor to prevent layers or stationary hot air forming
in the upper part of the room.
Louvres can be placed on intermediate positions by using
the remote control; as well the louvres may be set to
move continuously, sweep mode. (For more information,
see the remote control manual.)
