yup that's right grey goes to the boiler how do i remove the programmer to check wiring there, is it just a matter of unscrewing the two walls screws for it? also is there a way for me to check the bdr works as it should? should i draw up a wiring chart for that 10 port junction box?

honeywell box opened up for wiring. black wire (sticking out top left, partially covering round screw) looks like it has come loose. it feeds into boiler. white wire bundles (in top left corner) from left to right are programmer, ab from relay, nl from relay. wire bundles bottom right are...

apologies for the delayed reply. the AB wires go to terminals 7 and 8 in the honeywell box. brown to 7 blue to 8. these then go up to programmer (as a grey lead out of terminal 7) and to valve 2 below boiler (brown lead from terminal 8 . appears to be a loose black wire which goes to boiler...

have checked all four wires and terminals. and power is good to the relay. green light is on. wires in the relay go to two places it looks like. to the left they go to the zone control or honeywell white box. to the right they go to the boiler. have cleared binding and reattached relay to...

SE london near tower bridge. not sure im allowed to be more specific thanks echo will run through this all

the first i tried turning it and the thermostat off for a while then on again. does that count? would BG man have done this? dont know what signal level check would be. i have thermostat at 30c and on table 1 metre from boiler

sorry repeating his terminology. in the context he said it, it referred to the relay blocking the CH from coming on even after it had received a signal to do so

sorry and to reply to D_Hailsham it controls two different heat zones, and is controlled by a ST95OOC i have tested the thermostat pairing to see if when i turn the relay off the thermostat turns it back on, which it does

i don't and unfortunately not either have i been blagged?

how about now?

and the other piece

so here's the inside of the bdr

will pop it in in two hours or so

BG said the relay would register a call for CH. but when it signalled for the heating it (the relay) would then "trip out" and not signal for CH. he offered to replace for a HIVE system, i said fine, but when he opened up the BDR he said it was too badly wired for him to attach HIVE instead...

and here sorry 'know how to make photos smaller
