Generally, tado° is compatible with fully commissioned and functioning system boilers.
To check if tado° works with your system boiler, please refer to our Compatibility Guide:
Most system boilers come with an external domestic hot water tank. These systems divert heated water to different heating circuits. They use 2-port valves (S-plan system) or a 3-port valve (Y-plan system). In these cases, room thermostats and programmers are not wired directly to the boiler. Instead, they are connected to the boiler via a wiring centre.
If you have an S-plan or Y-plan system with existing controllers, tado° can replace them.
If you have a new system boiler without a controller, or want to connect tado° directly to your wiring centre, please contact a heating engineer.
tado° is not compatible with system boilers with a digital interface (e.g. OpenTherm/eBUS).
If you still need help with the compatibility of your heating system, please send us the brand and model name of:
the programmer that controls your system boiler
the room thermostat that you want to replace with tado°
If you can’t find this information, you can also send us some helpful pictures (pdf or jpg) of your devices.
