Thermostatic Valves
The Shelly thermostatic valve screws in place of the radiator knob and regulates the temperature room by room, with weekly programs and open window detection. You can mount it yourself in a few minutes without draining the system. For hosts in winter, it is one of the most direct ways to reduce utility bills: the empty house stays at a maintenance temperature and returns to warm just before the guest arrives. Together with a Shelly temperature sensor, regulation becomes more precise. If you prefer to entrust the mounting to someone else, you will find the dedicated service in the Installation category.
