I'm planning on putting a new DHW heat exchanger on my boiler tomorrow to replace the leaking original. Looks straightforward enough, but apparently if it is a hybrid model I need to cut a connection on the pcb. What is the difference, and is there a quick way to identify whether I have a hybrid model or not?

Oh well, thanks anyway, but I've sorted it now. It transpired I do have a hybrid so had to cut the bridging wire W18. Anyone interested might want to have a little look here.
