Kieback&Peter DDC4000 System
The kit for any automation: DDC controllers, gateways, I/O modules

The 4000 System from Kieback&Peter covers gateways, I/O modules and automation stations in the DDC4000 series. This trio provides maximum flexibility and scalability. With the 4000 System, we can realize any automation projects for you – from a small ventilation system to complex interdisciplinary projects involving multiple properties and technical systems. As a leading system integrator, we link devices and BS components from any manufacturers in the building. Digital or analog bus signals, cable or wireless: with the 4000 System, we can control any bus system and protocol in home or building automation. Our controllers offer native communication via BACnet and LON. We integrate other languages such as KNX or DALI securely through gateways. Our I/O modules have numerous, freely configurable connections. The 4000 System integrates controllers, sensors and actuators in all BS: heating, ventilation, A/C, shading, lighting, fire safety and anything else you can think of. There are no secrets with us: the 4000 System is open and transparent to everyone to whom you grant access.
The 4000 System from Kieback&Peter links all technical building systems easily. Whether by cable or wireless – it integrates all home and building automation protocols.
Organize your control system yourself!

As an operator, you will benefit from our open source philosophy: you can plan and modify the control of your systems yourself at any time if you wish. The 4000 System puts 94 preconfigured objects at your disposal. Each object contains the typical control patterns for a specific assembly – such as a ventilation fan or a heating pump. The entire expertise that Kieback&Peter has built up since 1927 is in our object library. You can install the ready-made objects as they are. Or you can adjust the control specifications to meet your needs – e.g. by determining new setpoints or changing the regulating and performance variables. You can determine how your systems are controlled yourself, independently of us and other manufacturers. Of course, this requires a certain level of technical knowledge, which you can acquire or extend in the Kieback&Peter training center. If you would prefer to leave the detailed work to the professionals: we are happy to handle the planning, installation and maintenance for your sytems.
Future-proof BS planning – with solid, scalable systems

New build and renovation projects often bring difficult decisions: investors and developers expect security of investment and want a good return on investment (ROI). They rely on the expert recommendation of architects and planners. Technical building services (BS) play an important part here. Buildings with fragile, inefficient technology, after all, are less useful and lead to higher operating costs. This reduces their market value. As a technical building services planner, you can always rely on Kieback&Peter: our products work stable and efficiently over decades – in some cases, they last longer than the building itself. We manufacture only in Germany to the highest standards of quality and sustainability. Our 4000 System is compatible upwards and downwards. It integrates both existing systems and newer installations cost-effectively using I/O modules and gateways. With particularly exotic or outdated technology, the system integrators from Kieback&Peter help with hardware and software migration and, if necessary, virtualization.
4 good reasons for the 4000 System
The flexible, open-source design of the 4000 System keeps all the options open for developers, planners and operators:
- The modular conception allows you to expand your building automation as required. The maximum number of data points is not restricted.
- Our controllers offer native handling of BACnet and LON protocols. We integrate all other protocols in home and building automation and all connection types from the various manufacturers via gateways and I/O modules. The expert system integrators from Kieback&Peter can help in tricky cases.
- The powerful controllers of the DDC4000 series allow integration of up to 600 field devices (sensors, actuators, etc.) per automation station.
- I/O modules are freely configurable and can process both digital and analog signals from field devices.
- The field-proven bus system ensures fast control processes.
As an operator, you can plan and modify the control of your systems yourself in detail if you wish. To help you, 94 ready-made control objects are available to you in the Kieback&Peter object library. You can combine them like building blocks and configure and connect them as required – including during ongoing operation. Kieback&Peter’s entire ICE expertise gained over 90 years goes into the objects. Configure your control system yourself or put your trust in Kieback&Peter Services.
You can operate the 4000 System controllers via a touchscreen on the control cabinet. Or by remote access from your PC or mobile device. You don’t need to install additional software – a current web browser is sufficient. We can adapt the user interface individually to your requirements. All the building service components are displayed schematically on the screen. Behavior over time can also be displayed clearly. The 4000 System is self-explanatory to use – even laymen can understand the basics of the systems. If you have more expertise, you can make changes to parameters such as temperature or airflow with just a few clicks. Definable user rights for service and operator level also guarantee protection from unauthorized access.
