Abstract

La présente invention concerne un appareil électrique (104) disposé au sein d'un foyer et qui fonctionne dans un premier mode ou dans un second mode qui présente des fonctions plus restreintes que le premier mode. Une unité de réception (503) reçoit, par l'intermédiaire d'un dispositif de commande (105) disposé au sein du foyer, une instruction aux fins de fonctionnement à distance de l'appareil électrique (104) en provenance d'un dispositif terminal à l'extérieur du foyer. Une unité de fonctionnement (505) fonctionne sur la base de l'instruction de fonctionnement à distance reçue. Une unité de détermination de commutation (504) détermine si des conditions de commutation sont satisfaites sur la base de résultats déterminant si une défaillance de communication s'est produite dans un trajet de communication utilisé dans le fonctionnement à distance. L'unité de fonctionnement (505) commute du premier mode au second mode lorsqu'il est déterminé que les conditions de commutation sont satisfaites.
