The HomeDialog system allows an appliance in a separate room to be conveniently controlled from the display of your fridge freezer (with HomeDialog capability). The PremiumPlus electronic control system (master appliance) shows the connected appliances in the display. Temperature alarms, door alarms or power failure of the external appliance are displayed on the master appliance. All the functions of the networked appliance, such as setting the temperature or SuperFrost mode, can be operated via the display of the master appliance. The Liebherr appliances with networking capability include wine cabinets, freezers, refrigerators and combined fridge-freezers. As many as six further Liebherr appliances can be networked using only the PLC home bus module available as an accessory. To enable networking, the appliances have to be interconnected by the same electrical ring main. Time-consuming cable routing is not required. Many further models are HomeDialog-ready for installing the retrofit kit and home bus module.
