So, im now about a week in with my new evohome system and things have definitely changed / been learnt with by the system about the rooms etc.
One thing i have noticed is that when a valve calls for heat it doenst necessarily open the valve from 0% to 100%, it sounds like its controlling the opening position, perhaps based on current room temp versus required room temp. i.e. it can go from 0% to 40% etc. The reason i ask is that i noticed my farthest rad on the system (living room) had a small whooshing noise last night when operating even though the lockshield is 100% open, this wasnt happening previously either using the HR92 or with the standard TRV head.
Its not a problem, just wanted to know more about the control philosophy.
