4x tado° Smart Radiator Buttons - expansion

tado° selection tool: to control your rooms independently with radiators, you can expand your Starter Kit with additional Smart Radiator Buttons. You need one Smart Radiator Button per radiator.

tado° can save even more on your heating costs and make life more comfortable by controlling each room. The basis of your setup is a tado° Starter Kit (V2, V3, V3+) with the Internet Bridge to connect to the Internet. Add additional Smart Thermostats and Smart Radiator Buttons to gain even more control over your home climate. Control multiple heating zones and rooms separately. That way you always have the right temperature at the right time in each room or zone. You can manage all zones in the tado° app for a clear overview.

Please note! To use the Smart Radiator Buttons, you need the Tado Internet Bridge.

Smart Radiator Button Compatibility

Please note! tado° Smart Radiator Buttons only work with thermostatic radiator valves. tado° replaces your existing thermostat button. Most thermostatic radiator valves (compatible) have numbers, screens or other control knobs. tado° is not compatible with manual valves. Manual valves usually do not have digits or buttons. There may be plus and minus (or on and off) signs on a manual valve, indicating the direction of rotation.

If you have thermostatic valves, check tado°'s "Compatibility Guide for Smart Radiator Knobs" (found at the bottom of the product specifications under Documents: view guide) for a list of the most common brands compatible with tado° Smart Radiator Knobs. This is because the tado° Smart Radiator Button does not work with all brands of radiator valves. Therefore, please check in advance which brand of thermostat knob you currently have.

  • The tado° Smart Radiator Knob is compatible with radiator valves from Danfoss, Caleffi, Comap, Giacomini, Herz, Olymp, Siemens and Terrier.
  • The tado° Smart Radiator Knob is only compatible with radiator valves from Vaillant, Oventrop, Ista and Orkli via an adapter. An adapter for these brands is not included by tado°.
