Inside the normal settings menu or the system installer menu ? It looks like the latter but its hard to see in the picture.
A little bit disappointing if there is no indication on the home screen and it is only available in the "hidden" installer menu that most normal users will not know about.
An icon indicating an approximate no/low/med/high heat demand on the home screen for each zone and the actual percentage in the settings menu as depicted would have been ideal, but I'll take what I can get!
It sure will make troubleshooting phantom heat demand issues a lot easier.
