Comfort, security and energy efficiency. Set to match your needs. Quick to install. Flexibly adjustable. With up to 80% fewer wires. Cost-effective. Highest security classification possible. And all from a single source.

Building automation with the Woertz flat wire system

Woertz KNX building installation provides complete solutions from a single source: KNX actuators, sensors and wiring for central as well as decentralised KNX systems. We’ve made it our mission to produce building automation that saves energy and materials. This is made possible by decentralised intelligence in our flat wire system.

The innovative solution

Building wiring with combined decentralised and central intelligence

Decentralised installation

The decentralised Woertz system is ideal for large spaces, corridors, and for using Woertz room boxes in small, modular rooms. The decentralised installation with distributed intelligence in the Woertz flat wire system makes it possible to install without a central control cabinet.

Elements and fuses are laid directly on the wire. All Woertz actuators and sensors are connected together with one flat wire and guarantee energy-saving operation.

Up to 80% of wires can be saved compared with traditional installations. Not only does this significantly save resources, it also speeds up installation and massively reduces the risk of failure.

Advantages of decentralised installation

  • Save up to 80% of wires
  • Can be extended flexibly at any time with individual sensors or components
  • Huge reduction in installation time thanks to piercing technology
  • Detection of interruptors for automatic run-time measurements
  • Built-in logic functions
  • Autonomous output control
  • Set behaviour in case of bus voltage failure and return
  • Manual control on device (test button) to check function and rotation direction
  • Multiple control functions and mechanically coded plug connections
  • Centralised control for all shutter outputs possible (commands from a weather control panel)
  • Allocation to up to 3 different security objects (e.g. for wind, rain, alarm)

Central installation

Control from a centralised point is ideal for small spaces. The pre-programmed, compact room box with pluggable wiring and built-in security permits central control of users and sensors connected.

Combination of decentralised and central installation

Control from a centralised point is ideal for small spaces.

The pre-programmed, compact room box with pluggable wiring and built-in security permits central control of users and sensors connected.

This means that pre-programmed room wiring can be installed again in a very short time.

Piercing contact in the flat wire method

Piercing technology makes junctions possible without interrupting the flat wire or using any special tools. Contact takes place using measuring technology in which the pointed screw penetrates the insulation and enters the wire strand.
The stretching creates contact pressure that is good for current transmission between the wires and guarantees low resistance values. The flat wire system permits sustainable installation for building wiring.

Product systems, Building automation

Flat wire system, actuators – KNX

KNX is a standardised bus system following international standards. It regulates reliable communication up to 14,400 sensors and actuators using telegrams via the bus wire built into the flat wire.

For example, the KNX can control lighting, blinds and sunshades as well as heating and locking and alarm systems. KNX also makes it possible to monitor and manage a building remotely.

KNX is now mostly installed in new residential and functional buildings, but it can also be retrofitted to older buildings when renovating them.

DALI flat wire system

DALI (Digital Addressable Lighting Interface) is a control ptrocol for digital, photometric operating equipment in buildings, such as lamps with electronic transformers, electronic ballasts and electronic power dimmers.

Operating equipment with a DALI interface can be controlled individually using DALI short addresses. Two-way data transfer allows a DALI control device or a DALI gateway to request the status of lights or light-operating equipment. DALI can be operated as an ‘island system’ with a maximum of 64 operating devices or as a substem via DALI gateways in modern building-automation systems.

Bus / multibus flat wire system

These flat wire systems with bus wires permit the widest array of functions in building automation for LON or SMI applications.

LON (Local Operating Network) is a fieldbus system predominantly used in building automation. The bus system originated in the US and was developed in 1990. It permits neutral information transfer between facilities and devices from different manufacturers and independently of uses and applications.

SMI flat wire system

SMI 230 VAC or LoVo drives with IP20/40 or IP66/68 flat wire system.

SMI (Standard Motor Interface) is a fieldbus system to control electronic devices (stepper motors) for blinds, shutters or windows and ventilation flaps. It can be operated on its own but is usually incorporated into higher-level systems like KNX. In additional to simpler wiring, its key advantage over conventional drives is its feedback capability.
