Deactivating a room or system allows you 'hide' a room/system or save it for later without completely deleting it. When you deactivate a room or system it won't show up on your reports.
To deactivate a room/system go into the builder and hover the cursor over the room/system, then click on the edit icon that appears to the right.
This will open an 'Edit Room' modal. Click 'Deactivate' on the bottom left.
The deactivated room/system will appear under 'Inactive Rooms' where it can be reactivated by hovering the cursor over the room/system and clicking the edit icon.
Please let us know if you have any questions about this!
