i have just moved in to a house with the drayton digistat RF2 wireless system and although i can set times for heating to come on i have no option to set the time for it to go off, also heating does not come on at the times i set but when it feels like it and only for about 10 mins
Assuming you are of average intelligence, (I have my doubts), then it is really quite simple. The selected temperatures are THE OFF/ON TIMES. e.g. if you set the temperature to 7deg at midnight then the boiler turns off - unless it's extremely cold.
