Hi Picasso,
Thanks for the response, just had a chance to follow the wiring back to the boiler in the airing cupboard.
I have found a junction box in the airing cupboard - wiring picture attached, looks like the blue wire is not connected at either end - digistat controller or past this...
Hi Folks,
We have a Worcester Bosch 37CDI combi boiler controlled by a Digistat 3+ controller.
We are looking to replace the controller with a Hive single channel unit.
But my Digistat controller only has 2 wires connected in the wall box, as per attached picture, red to 'C' and Yellow to 'ON'...
