Heat line info in the app
Hi , Can someone please tell me what the three squiggle heat lines are beside the temperature on the room app? Ie It is set to 20 the room is currently 19 so the room is heating. Sometimes only one line is showing and the other two are greyed out. Sometimes all three lines are highlighted.
I guess that one line means the Boiler is only heating gently . All three mean it's on full? Just wondered what the significants of this is?
