A perfect match – System technology

"The whole is greater than the sum of its parts". Following this philosophy, Viessmann supplies more than high quality, reliable and effective heating components.

In fact, all products are part of a matching total concept, where all components complement one another. After all, only perfect interaction between all system components can draw out the maximum potential of our innovative leading technology.

Viessmann system technology incorporates everything you need for a reliable and economical heating system: From the Vitotronic control unit with wireless remote control, powerful Vitocell DHW cylinders for the highest DHW convenience, right up to high grade solar thermal systems for cost effective central heating backup.


Standard control units from 1.5 to 2000 kW

With increasing demands for efficient, multi mode and user-friendly heating systems, the control unit gains ever more importance. As a response to this demand, Viessmann now offers a standard range of control units in the shape of the Vitotronic 200/300 that is suitable for all small boilers, wall mounted boilers, medium-sized boilers and heat pumps.

Operation with user prompts

Operation with user prompts is easy and intuitive. This is supported by standard controls, a large backlit graphic display with several plain text lines, a high contrast monochrome depiction and a context-sensitive help function accessible via the "?" key. Special functions, such as heating curve, solar yield and switching times are depicted graphically.

Vitotronic 200 simulation software

See for yourself how easy it is to operate and adjust the Vitotronic 200. The simulation software is available to download here as an executable file. It runs on PCs and notebooks under MS Windows XP or Windows 7.

Save the ZIP file on your PC and unpack the file into a folder of your choice. Then start the application by double clicking on the unpacked file.

End the simulation by right-clicking on the application and selecting "Exit" or by using key combination "Alt + F4".

Regelungsprogramm für Mittel- und Großkessel – wirtschaftliches Energiemanagement für alle Anlagengrößen

Von der Einkessel- bis hin zur Mehrkesselregelung mit zentraler Schaltschrankbedienung liefert Viessmann ideal aufeinander abgestimmte Lösungen. Das kommunikationsfähige Regelungssystem Vitotronic ist das elektronische Management für wirtschaftlichen und sicheren Betrieb der Heizungsanlage – vorbildlich in Montage, Bedienung und Wartung.

Für die Mittel- und Großkessel steht ein breites Regelungsprogramm zur Verfügung. Neben den integrierten Regelungen, beispielsweise beim Gas-Brennwertkessel Vitocrossal 300 (CM3C), gibt es auch Varianten, die in bewährter Weise auf der Oberseite des Kessels montiert werden können.

Remote control units

With their attractive design and white, high-gloss casing, the remote controls in the new Vitotronic control unit range are ideal for use in living spaces.

Thanks to a standardised operating philosophy, the new Vitotronic units are straightforward and intuitive to use and quickly provide an overview of the heating system at all times.


Vitotrol app

The Viessmann Vitotrol app enables you to operate Viessmann heating systems equipped with Vitotronic control units. Operation from anywhere and at any time is easy, intuitive and convenient. Alongside its operating functions, the Vitotrol app features general and context-sensitive help functions. The Vitotrol app is available for mobile devices with iOS or Android operating systems.

In order to operate the app, the wall mounted boilers / small boilers / medium-sized boilers / heat pumps / wood boilers with Vitotronic 200 (see "Usage requirements" for control unit types) must be equipped with the Vitocom 100 LAN1 interface and linked to the domestic broadband router. Configuration of the DSL router is not required.

Domestic hot water cylinders

In the Vitocell cylinder range, you'll find exactly the right DHW cylinder for your requirements. Depending on your DHW demand and the installation conditions, you can choose a DHW cylinder for installation adjacent to or below the boiler.

Hygienic DHW provision

The quality of the inner surface of the DHW cylinder is crucial to providing DHW hygienically. For this reason, Viessmann relies on two high quality materials: the first being Ceraprotect enamel coating for safe, lasting protection against corrosion for the Vitocell 100 range. Secondly, stainless steel is the "guardian angel" of the Vitocell 300 range, satisfying the highest hygienic requirements.


Data communication

From holiday home and utility building to large apartment complexes - the Viessmann TeleControl range offers intelligent solutions for data communication with heating systems and building services.

This applies to all available heating systems: Oil or gas condensing boilers, medium and industrial/commercial oil/gas boilers, solar thermal systems as well as pellet boilers and heat pumps.

Vitoset fuel oil tanks for any demand

Vitoset fuel oil tanks in sizes relevant to the specific boiler are available for any demand. They are certified for storing fuel oil with capacities up to 5000 litres in rooms where combustion equipment is located. [German] regulations require separate storage rooms for greater volumes of fuel oil. Vitoset fuel oil tanks can be arranged in banks with a total capacity of up to 25,000 litres of fuel oil. They are the right choice for new build, extensions or renovations – in detached houses and apartment buildings as well as in residential complexes or commercial buildings.


Freshwater modules

Freshwater modules are used for convenient and hygienic DHW heating in accordance with the instantaneous water heater principle. In contrast to conventional DHW cylinders, the drinking water is not used for storing thermal energy but instead is only heated when required, by means of a powerful plate heat exchanger. The energy for this DHW heating is drawn from a heating water buffer cylinder, which can be heated by a wide range of systems – by solar thermal systems, or by solid fuel boilers, conventional oil/gas boilers, heat pumps or other systems.
