Key advantages of EIB/KNX – Instabus electrical installation

1. Introduction – comparison with a conventional electrical installation.

Traditional electrical installations comprise several separate circuits, each of which serves an appliance, a group of similar appliances or a particular functional group. That is, we have electrical circuits for lighting, heating, traffic, air conditioning, fire detection, alarms, telephones, data transmission networks, etc. The prevailing practice – until recently – was to build separate automation devices for each circuit. However, this creates problems of coordination and monitoring of the overall operation of all the installations in a building or in an apartment, thus multiplying the complexity and the cost of construction and maintenance of the electrical installation, while the handling of the various devices becomes more and more complex, making it difficult for the users of the devices.

The philosophy of EIB/KNX technology aims to build smart, functional and at the same time unique homes and commercial buildings. The EIB/KNX application offers the user services that a conventional electrical installation in many cases is unable to provide or requires huge design and installation costs. The EIB/CNC technique uses the bus network to which all the devices and parts of the electrical installation are connected, so that they can “communicate” with each other according to specific programming. This has the effect of reducing the number of cables involved in the implementation of electrical installations.

2. What are the benefits of the new EIB technique?

The advantages of the EIB/KNX – Instabus system are presented below:

COMFORT

Indicative functions that can be performed simultaneously, with the push of a button, are many, such as turning off the lights, turning off the air conditioning, lowering the electric shutters in the room and generally creating scenarios that enhance the user’s quality of life.

FLEXIBILITY

During the lifetime of a building, changes are inevitable. With the new techniques there is the possibility of flexibility in the expansion of the system and in case of differentiation of the needs and requirements of the user, intervention in the electrical installation is not required in the sense of disconnecting the cables etc. but is achieved by reprogramming the automation scenario. Also, the programming is easy and user-friendly.

SAFETY

Of primary importance in any electrical installation is the term safety. With the application of the new HIB/CNC techniques, the risk of fire is minimized as a result of the reduction of the number of cables involved in the installation. The 230V voltage is no longer present at the control points. In addition, there are applications that secure the user during his presence or absence from the building.

ECONOMY

A reduction in power consumption is achieved by adjusting e.g. the lighting. Due to the flexibility of the EIB technical installation, costs related to any changes that may be required in the future are significantly avoided.

ENERGY SAVING

Certainly, it is the cost of running the building that concerns us directly and is of most concern to us. A building, a house or a hotel with a new technique in its electrical installation can become a “smart” building. For example, in an office building, occupancy sensors can be installed to control air conditioning and lighting depending on the presence or absence of people in the room. The lighting can also be controlled according to the natural lighting outside.

SCALABILITY

• The system is fully scalable, with a choice of devices from a variety of companies.
• The installation of extra devices requires only an interface to the BUS network (the connection is made at the nearest BUS point).
• Δυνατότητα διασύνδεσης με BMS (Building Management System).

With the HIB/CNC technique, the electrical installation is adapted to the needs and requirements of the user. It is now becoming friendly and human. It makes sense and covers not only its present needs but also its future needs.
