Generally, tado° is compatible with fully commissioned and functioning system boilers.
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).
To check if tado° works with your system boiler, please refer to our Compatibility Guide.
If you still need help with the compatibility of your heating system, please contact us via chat with the brand and model name of:
the programmer that controls your system boiler
the room thermostat that you want to replace with tado°
