    If you need to replace it you have to disconnect the ribbon between the DT10 and the boilers PCB, no links required but the new receiver will have to be hard wired to the boiler

    Thank you for the help and both of your time!

    I turned off the water using the left hand button (so indicator pointing to OFF) and it doesn’t seem to have made any difference. Boiler still making noise and temperature still showing around 50C. I turned it it to ON and then OFF again and interestingly it turned off the ECO light when it’s ON and it turns off the ECO light when it’s OFF which would match with what you were saying about how it’s this programmer that controls the pre-heat. I’m still getting hot water when it’s OFF as expected. Any other ideas?
