@lajos88 so when tado heads are unmounted, valves will be auto open and remains open? No need to do anything more before that?

No need to set the temperature to 25 degrees or turn off the boiler, etc.?

Ty!

This is funny why would be bother removing the thermostats every time when we want to bleed the radiators. This is a very sensible feature request -> Bleed Mode.

please let us leave the smart valve fully opened all the time and work only as a temperature sensor and for calling heating from the boiler

Definitely need this function.

Most thermostatic valves get stuck if they are left in a CLOSED position for an extended period of time. In order to prevent this we could either 1) leave all valves OPEN when heating is off - if the heater does not work, it makes no difference which position the valves are, and in OPEN position they do not stuck. Or 2) make a new “Off Heating Season” setting that switches heating off and OPENS all thermostatic valves.

IMHO an even better solution would be for the thermostats to regularly "exercise" the valves.

This should be programmed to run regularly, and automatically if you switch all heating OFF.

The same goes for UFH pump controlled by Tado thermostat.

Yup this is quite important. Unless Tado already does this with occasional full open and closing (which I have seen once I think when I had the heating off), but then there should be some information about this somewhere and its frequency or required conditions.

Otherwise I'm taking the Tado TRVs off in summer.
