tado° is only compatible with thermostatic radiator valves. You can check what kind of radiator valves you have here.

If you have thermostatic valves, check our this Compatibility Guide to find a list of the most common options that are compatible with tado° Smart Radiator Thermostats. You might need to install the Smart Radiator Thermostat with one of the adapters provided in the packaging.

Smart Radiator Thermostats replace your existing thermostatic radiator valve (TRV) heads. The Smart Radiator Thermostats fit almost any valve body, either directly or by using an adapter.
