Just like to say thanks for your help, it ended up being a damaged core in the flex. no idea how that happened as its a first that i know about from a core(blue) to break...strange, anyway boiler is up and running, thanks again for your help/guidance.
ok will check tomorrow night when im next at the house, how can i check the voltage on the reciever without the front on though? as the front has the circuit board built in?
cheers, however im 99% certain i tried that method,and it still wouldnt work, the receiver lights up when the programmer is switched on to manual or the when timer kicks in but it doesnt start the boiler up ??
Hi i am trying to wire the receiver of the honeywell cmt921 to my worcester 28i, but the wiring diagram do not seem to be clear, please can someone tell me how this has to be wired? thanks.
