Hi All,
Rather than explain myself really badly, to understand my problem, if you have the time take a look at http://www.diynot.com/forums/viewtop...033634#2033634
Basically - If you havn't read the above, I am trying to automate the hot water and central heating.
I have it setup so the controller/programmer has heating + hot water constantly on, and relays inbetween HW ON and CH ON after the programmer.
This isn't fully working, as the Y plan wiring needs/expects a HW OFF and I think this is what is causing an issue with central heating not turning on. One possibility is to have yet another relay for the HW OFF ?
I am not quite sure how to get past this one.
