If you have any questions or need help after purchasing a Homematic IP product, please contact our Technical Support Center Monday to Friday between 9:30 and 49 491 6008 683. The Homematic IP radiator thermostat - basic is part of the Homematic IP smart home system and actively helps to save energy. The smart controller replaces conventional radiator thermostats which can achieve energy savings of up to 30%. The thermostat is mounted on the radiator without interference with the heating system and without tools. The power supply takes over two AA batteries, which energy for approx. 2 years. Thanks to the preset heating profile, the radiator thermostat can be used immediately - this can be manually adjusted at any time if required. Individual temperature gradients are possible per day with up to 13 changes. Homematic IP heats certain rooms only when really needed. The setup can be done flexibly on the device itself, via Homematic IP app (in conjunction with the Homematic IP Access Point) or via a browser-based interface (in conjunction with a central CCU2/CCU3). Alternatively, the smart thermostat can also be operated without a central unit: the stand-alone operation (push-to-pair) allows you to directly learn up to eight window and door contacts with magnet (HmIP-SWDM) to automatically lower the room temperature when ventilating. The radiator thermostat can be integrated into a comprehensive smart home system via the app. The cloud solution allows you to adjust the temperature at any time from any place. If you prefer to know the data locally on your home network, but still want to benefit from the benefits of a smart home system, you can refer to the setup via the CCU3. Numerous additional functions: boost function for quick heating of the room. Eco mode for energy-saving operation with reduced room temperature. Valve protection function to protect the valve from limescale. Operating lock to protect against unwanted operation. Flexible control options: Stand-alone operation (push-to-pair): manual operation and configuration directly on the device, e.g. B. Setting a heating profile, holiday mode, temperature changes and much more. Direct learning of up to eight window and door contacts (B07WXYL294) and a wall thermostat (B07ZHMGRLF). Flexible extension to a comprehensive smart home possible at any time.
