Read full descriptionHide full description
The Smart Control app from CLAGE is compatible with all systems for tablets and smartphones. With the app, the hot water supply in the house or flat can be operated digitally. The app enables comfortable control of CLAGE electronic instantaneous water heaters through an intuitive user interface for convenient setting of the desired water temperatures, as well as the option of setting up additional functions. The content of the app automatically adapts to the range of functions of the connected device. When connected to a DSX Touch or ISX, all functions are accessible. When connected to a CEX, for example, functions for motor valve and WLAN settings are hidden because they are not available in the instantaneous water heater. A view at the display is enough to check water and energy consumption as well as the costs for the selected period. The user can adjust his consumption behaviour, save costs and thus protect the environment. NOTE: A CLAGE instantaneous water heater with Bluetooth function is required to use this app. Models with Bluetooth ex works: DSX Touch (from year of manufacture 2020), ISX, DEX Next S, DSX Touch Twin, ISX Twin, CFX (from year of manufacture 2022). To ensure full functionality, the following enables are required: - Bluetooth (for device search and communication) - WLAN and device search (only for DSX Touch and ISX for access to all functions of the integrated home server) - Camera (for QR code scanning) - Memory (for recording statistical data) Alternatively, an FXE3 Bluetooth radio adapter is available for retrofitting to compatible models. Compatible models: DEX Next, DEX12 Next (from year of manufacture 2020), CEX, CEX-U, CEX9, CEX9-U, MCX (from year of manufacture 2022) For further information, please visit our homepage at: https://www.clage.com/en/products/other-products/FX3 Please also note our instructions for use and assembly at: https://www.clage.com
