, you need to find the wire that is live when calling for heating, remove this from block and connect to reciver, then back from reciver to were the wire went into the block, so that you are making a loop through the reciver hope this makes sense.
In the fuse spur next to controller there's a live feed from the valve to the boiler, joined on a piece of choc block. Do you reckon I'd get away with looping that thru LX & L1?
Makes sense to me, but then I do be a bit daft!!
Click on timer for heating / see whitch wire is then live in J/box that is then switchd live from timer, pull out this wire put on choc block, then extendd this wire into receiver, then from other connection in reciver run this back to the connection that you took the first wire from so that you make a loop P/Live -N - E needs to be from spur.
Thought of a possible issue with connecting via the switched live, wouldn't that hold off the boiler when it's calling for DHW only?
Looks like I'm gonna have to connect at the valve...:ack2:
No you are only brakeing into the heating SL not the hot water, timer calls for heat for heating, sends signel to room stat this then sends signel back to wireing center, remember that SL for hot and SL for heating go to differant terminals in wireing center.
