   1. 
  Familiarisation with window frames.   | 
  
   The Merit user interface
  consists of three sub window frames as shown below. The top-left window frame
  supports the definition of climate, demand profiles, renewable energy
  systems, auxiliary systems, fuel supply and matching analysis.   Depending on your current focus,
  the top-right window frame allows you to specify the details of the
  particular demand or supply, or control the combination of demand/supply
  options for the matching analysis function of Merit.   The top-right two window frames
  show what specific demand, supply and auxiliary system you have selected.
  Depending on the electricity or thermal type, they will show in different
  windows separately. To switch to a different energy form, you can click on the
  tabs at the bottom of this frame.        The bottom frame displays the
  results of your current analysis, or, if you are selecting a profile, it will
  display a graph of the profile.  To change your focus, you can click on the tabs at the
  bottom of each of the frames.

   2. Explore menus.  | 
  
   Within the upper-left frame you select items by right-clicking on the label. The figure below shows the result of a right-click on the Demands Selected item. The Load demand pop-up (in the upper-left frame) has caused a Demand Database Connection... window to appear in the upper-right frame. Explore other sub-element areas in the same way.
