            The Potterton EP 2000 was a popular central heating 
              and hot water controller marketed in the 1980s. It was simple to 
              set-up and operate, but because of its versatility was a little 
              complicated to wire-up. 
            I had one, but it was eventually retired and sold 
              on when my heating system was upgraded. 
            There have been several posts asking for the installation 
              and wiring instructions, so I hope this download may be of help 
              to anyone who needs it.
