Hi there, just got a replacement programmer as my old one is playing up.
I'm replacing a Drayton lp241 with a Siemens Rbw27. I think I need to change my wiring around a little to suit. On my old programmer I only have to control my heating and on my new one it only has the heating function. I have a gravity fed system. Here are some photos to help me explain.
