Almost all electrical installations in the user’s house are integrated in one overarching system, the bus system. The system is programmable and can be controlled with a transmitter (see associated tip). Each room also has programmable wall contacts (see photo 1) that can control the electricity in the rest of the house. Wall contacts in the bedroom control functions such as the ceiling lamp and window opener, but you can also turn out all the lights in the house and control the outdoor lighting.
A large distribution board is located on the bottom floor of the house (photo 3) from which the bus system can be programmed. A technician must do this.
The system is extremely expensive and the user is not sure that the installation was worth it. The electrician has to be a specialist in the Bus System in order to take care of it. He wonders what will happen in 5 or 6 years if the system begins to have problems; the technology and/or the same supplier might not still be around.
The user feels extremely dependent on electricity, though to date he has not had a power outage/cut.
