  • New apps for heating, ventilating, cooling and hot water supply

  • Quickly and easily adapted to individual requirements

  • Free for iPhone and Android smartphones

The German heating and ventilation specialist Vaillant is presenting two new smartphone apps at the ISH industry trade fair in Frankfurt am Main. The two apps, multiMATIC and eRELAX, are free and enable users to control their heating remotely with ease. Both apps are characterised by their simple and intuitive use. Users can set up their heating to a range of regular situations – “Home”, “Night-time” or “Away” – via the homepage. Spontaneous changes can also be carried out via a fast-access point on the home page. This includes situation-relevant settings such as “Holiday”, “Day at home” or “Quick airing”. In these cases, the system is powered up or down for a specific period by using the touchpad. By setting up various profiles, several members of the same household can use the same app to adjust the heating to their own requirements. In addition, various heating zones can be set up within one system, such as for living rooms and bedrooms. It is also possible to control several heating systems with both apps. An integrated demo version shows the user the major functions and how to use the app. The apps are available for the iPhone and Android smartphones.

The multiMATIC app is suitable for high-efficiency, natural gas-based heating units, but also for technologies using renewable energies, such as heat pumps and ventilation systems. The eRELAX app was designed for retrofitting existing heating systems.

“The digitalisation of our daily lives is set to continue in every area. In the future, smart systems will become standard in heating technology. Heating appliances will feature smart connectivity and we will be able to control them from anywhere,” says Dr Carsten Voigtländer, CEO of the Vaillant Group. The two new apps are part of a comprehensive, Group-wide digital strategy that extends across all areas of business, both internally and externally. In addition to the intelligent connectivity of products and components, this strategy also involves the development of new digital connectivity models and models to facilitate dialogue with skilled technicians and end customers. “We have been offering our end customers and skilled technicians a personalised, individual service for many years now. In future, we will also be able to offer a comprehensive range of digital services and communication options across the entire value chain. Customers will then be able to choose the option that suits them best,” Voigtländer continues. A completely new website and online platform to bring Vaillant’s partners – skilled technicians – together to develop new areas of digital focus for the future are the first projects in this new strategy.
