Lambdatronic 5000 controller
With the new Lambdatronic 5000 boiler controller and the modern 7″ glass touch display, Fröling is moving into the future. The new design is impressive, not only for its intuitive operation but also its numerous new features. The most important
components can be freely selected in the tile overview and information and error messages can be customised. For example, the control system will inform you when the ash box needs to be emptied. This makes operating and running the system even simpler and easier to understand. The intelligent control management enables the almost unlimited integration of heating circuits, storage tanks and hot water tanks.
Advantages
- Precise combustion control by a Lambda controller using a Lambda probe
- Connection of heating circuits, water heaters and buffer storage tanks Management systems
- Integration capability for a solar panel system
- LED frame for status display with illuminated presence detection
- Simple & intuitive operation
- Various SmartHome solutions (e.g. Loxone, Modbus TCP) Remote control from the Living room (room console) or via the Internet (froeling-connect.com)



Keep track of everything with the Froling App
The Froling App allows you to check and control your Froling boiler online from
anywhere, at any time. You can read and modify the main status information and settings easily and conveniently online. You can also specify which status messages you want to be informed about via SMS or e-mail (e.g. when the ash box is to be emptied or in the event of a fault message).
The app is available in the Android Play Store and iOS App Store.
Advantages
- Simple and intuitive operation of the boiler
- Status information can be called up and changed within seconds
- Individual naming of the heating circuits
- Changes of status are notified directly to the user (e.g. via
e-mail or push notifications) - No additional hardware required (such as an Internet gateway)
Smart Home
Loxone
Combine your Froling heating system with the Loxone Miniserver and the new Froling Extension and implement individual boiler control on the basis of the single room control of the Loxone Smart Home.
Modbus
Via the Froling modbus interface, the system can be integrated
into a building management system.
