Generally, tado° is compatible with fully commissioned and functioning system boilers.
System boilers are usually installed with an external domestic hot water tank. Such systems use 2-port valves (S-plan system) or a 3-port valve (Y-plan system) to divert the heated water to different heating circuits. In these cases, room thermostats and programmers are not wired directly to the boiler. Instead, they are connected to the boiler via a wiring center.
If you have an S-plan or Y-plan system and have existing controllers connected to it, tado° can replace these controllers.
If you have a new system boiler or want to connect tado° directly to your wiring center, it is best to get in touch with a heating engineer.
To find out if tado° is compatible with your system boiler, please contact us with:
