Hi All, dont want to appear thick, but my daughter has just got a new house, and it has a vokera 80 xl sp combi boiler, no problems diaphram just been changed all working well, but there is not manual with the boiler/house, my question is this, on the time clock, where do you set the hour of the day to, normally you would see a mark on the casing and align that to it, but i cant see any such mark do you set the hour at the top or at side whereabouts, many thanks dave
