||Simplicity combined with technology is the key to revolution. Based on the cubic capacity of your room, our thermostatic radiator head, calculates how much time it takes to reach the temperature you want. Moreover, the current temperature is indicated by the appropriate ring color. You no longer have to read the temperature on poor displays. Try, set your temperature and discover the color language. See how amazingly simple and efficient heating management can be. You can install the FIBARO Heat Controller on any number of radiators and they will co-operate with each other to provide the optimum temperature. No other controller offers such a level of heating comfort and such an array of possibilities. Wherever you are, whenever you are: use your hand, use your voice or use your mobile app to have precision control of the heating in every room in your home.
