I have just installed a worcester digistat to my boiler, i followed all instructions to the letter.
The unit learned correctly and the signal is clear and lights up as it should do but the boilers radiator light (and heating system) will not work.....even on overide the radiator light just flashes once per second.... the red button does not clear this, can anyone help please?

look for a link between the Ls and LR connections on the boiler, this is probably where your old hard wired room stat was wired in.

If there is no link, the new digistat won't work. Stick a link in and it should work.
