If I am following you correctly then I presume you are suggesting a
HW off connection from the programmer to terminal 5 to give seperate

Yes. There may be occasions - maybe when returning home from holiday to a
cold house, for instance - when you might want the heating on without
waiting for the hot water to heat up first.

Unfortunately, I can't get the pdf file, which you cite above, to load - so
I can't see what the rationale is for not having a CH-only mode.
