Energy saving tips
Set the economy temperature to just 5 °C below the room temperature (day
temperature). If you set the setback temperature lower, you lose the saving
effect, because a lot of energy is then needed to reheat the rooms. It is only
worth setting the setback temperature lower if you are going to be away for a
long time, e.g. on holiday.
The DHW circulation pump circulates the DHW through the pipework. This
ensures that hot water is always available for you at the draw-off points.
