Will radiator run full power if battery runs flat?

Some other brands (almost) fully open the valve just before the battery runs flat. Do the Tado X Thermostats do something like this as well?

If so, can I disable it? I don't need any kind of frost protection, as in-house temps never fall below 15°C.

    Hello @Goonie

    You can find an overview of what happens when batteries run flat here.

    If the Smart Radiator Thermostat doesn’t have enough battery power to close the radiator valve (or re-close after responding to a Frost Protection action), the valve can remain open and heat continuously. The best way to prevent this is to ensure your batteries never get to a state of complete or near depletion.

    For the other types of thermostats, overheating is unlikely as they do not control the valves.
