Abstract

Les modes de fonctionnement ne peuvent pas être modifiés involontairement par l'utilisateur. Une télécommande comprend : un bouton de commutation de mode de fonctionnement principal (44a) permettant de changer de mode de fonctionnement principal, y compris un mode de fonctionnement de refroidissement et un mode de fonctionnement de chauffage; et un bouton de commutation de mode de fonctionnement auxiliaire (43c) permettant de changer de mode de fonctionnement auxiliaire qui peut être réglé lorsque le mode de fonctionnement de chauffage est sélectionné en tant que mode de fonctionnement principal. Le bouton de commutation de mode de fonctionnement principal (44a) est situé dans une zone qui peut être recouverte par un élément couvercle (49) placé sur une partie corps principal (41) de façon ouvrable et fermable lorsque l'élément couvercle (49) est en position fermée. Le bouton de commutation de mode de fonctionnement auxiliaire (43c) est situé dans une zone qui n'est pas couverte par l'élément couvercle (49) lorsque l'élément couvercle (49) est en position fermée.
