Can anyone help i have a gloworm ultimate boiler, the rest of the system has danfoss components, the system has a hot water tank and one danfoss pump, problem is that the boiler comes on breifly at any time of the day or night even after the digital timer swith has shut off normally at 10.30pm the pump also seem to run non stop. if anyone could help that would be great.

Probable. Stuck micro switch in one of your motorised valve heads, giving a permenant live to boiler and pump .
