With this app, professionals can configure the ELS NFC mono-tube ventilation system easily, quickly and safely according to the design requirements. How it works Connect your Smartphone to ELS NFC with a simple touch - this works both on the installed device and in the packaging. The settings currently defined in the device are automatically displayed and can be adjusted directly. Another touch updates your ELS NFC with the new parameters. Once configured, parameters can be saved in the app, changed, shared and transferred to other devices – without power and without an internet connection. What can be set? Each ELS NFC offers three ventilation stages as well as basic ventilation and interval operation, each with definable volume flows of 7.5 to 100 m³/h. In addition, desired times for delayed start and overrun times can be saved individually for each ventilation level as well as interval times. Depending on the fan type, the app allows additional adjustments for the respective sensor control (humidity, presence, VOC or CO2). More features • The status overview provides information about the operating status of ELS NFC and displays currently measured sensor values and the volume flow. If necessary, detected problems and contact details can be sent directly from the app to Helios Support for clarification. • The volume flow adjustment can be used to compensate for on-site influencing factors. • Frequently used configurations can be saved in the library and assigned to projects. With search and filter functions, you always have an overview and can share configurations with your team. • The library contains a complete set of factory settings for all ELS NFC models, which can be reset at any time. • All relevant product information, from technical data to operating instructions for the selected device model, can be accessed via the app. Notes • The ELS NFC app is intended exclusively for professionals. The parameters defined in the design must be observed. For further information, please refer to the installation and operating instructions enclosed with the product. • The ELS NFC is configured exclusively via this app. Manual settings directly on the device are not possible.
