Is there any built-in function for preventing the valve from becoming stuck/calcified/etc. (in reality this happens more often than not)? E.g. fully closing and opening the valve periodically/on a schedule (e.g. not during the night, in order to not disturb people that are sleeping etc.)?
In order to prevent the valve from becoming stuck, other TRVs on the market have a built-in feature for fully opening and closing the valve once/a couple of times on a regular basis, independent of any active heating mode/schedule (after completing the open-close cycle, the valve returns to the position/mode/schedule in which it was before starting the cycle).
