Volute
Louvres change position to distribute air according to heating
or cooling operation.
• In cooling operation the louvres are positioned to distribute
air outwards from the discharge, which allow airflow close to
the ceiling.
• In heating 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.
Depending on the control, the louvres may be set on intermediate
positions; as well the louvres may be set to move continuously,
sweep mode. (For more information, see the remote control
manual.)
When the Electro-mechanical thermostat is used the louvres
movement is manual, louvres should be positioned manually.
