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 this Compatibility Guide to find a list of the most common options that are compatible with tado° Smart Radiator Thermostats.

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.

The screw nut for mounting the Smart Radiator Thermostat fits on any M30x1.5 radiator valve body thread. The included adapters allow mounting the device on many more valve types.
