Can you please tell me how to change the inside temperature?
If you mean the design temperature, then go to the Rooms menu, select Room data, choose the room you wish to edit, and then modify the data in the dialog that appears.
You can find helpful information for the CAD Input by pushing the F1 key when on the CAD Input page.
You can use Global Change to make changes such as this to multiple rooms. I would recommend reading the Global section of the manual - info here.
ScopeThis program enables you to make global changes either to the whole of your project or to specific rooms, zones and floors. An item to be changed globally is set up by simply specifying the required new value.
Select roomsSelect the group of rooms, zones or floors that you wish the global changes to be applied to. Be careful with your selection of rooms, as the global changes that you set up will be applied to all the rooms you have selected.
I would also suggest going through our Mechanical Designer course, which is available online for free for Select users - see details here.
