Hi all,
I am having trouble overwriting hot water loop scheduled setpoint temperature which is my case 90oC. I am leaving all object classes related to this. I am trying to put control in hot water loop, and that scheduled temperature varies with outside temperature, since this is the most common heating control in my country. Maybe I didn't understand EMS guide well, because whatever I do, setpoint remains 90
Here it comes!
