Upgrade to extension kit

I just upgraded to V3+ with extention kit, so to control hot tap water as well. My old thermostat V2 is connected to the new ethernet bridge, but is also wired. The new V3 thermostat is connected wireless. Should I disconnect the wiring of the old thermostat, or does the system regulate this itself?


  • The new thermostat is the same as the old thermostat so you don’t need to change it. The physical difference between V2 and V3+ is just the bridge.

    If the old thermostat is wired then it is directly controlling the boiler, so you cannot just go wireless without making changes to both the wiring and the server configuration. Tado support should have given you instructions.

    Why did you upgrade from V2 to V3+? Was it for Apple Home Kit?
