my "analogue" TRV's has got "Infinite" needle-positions....

meaning: they can control the ventil's-needle in a "step-less" way!


What about the Tado's?

they are digital - and they control through steps (by means of a step-motor/engine).

BUT, WITH HOW MANY STEPS DO THEY CONTROL THE NEEDLE??

4-16-256-xxx ???


My pre-assumttion:

A friend of mine, havd got these TRV's - and we hear the motor/engine move in very clear "big steps"..

and, from the "sound & app", it seems that there is ONLY 4 steps (off-min.-med.-max.)

Is that correct - or is there for instance 16, 256 steps in total ??

    I think the number of steps is quite limited, certainly nothing like the infinite variability of a conventional TRV. There is a lengthy post about this subject above . . .

    I believe just the 4 positions that you've identified based on my experience with the app and the corresponding valve adjustments that take place when the number of lines changes in the app
