Temperature Control
1. Central Heating: The central heating hot water
flow temperature can be adjusted between 30° C (±
5° C) minimum and 85° C (± 5° C) maximum.
2. Turn the control knob clockwise to increase the
temperature (Fig. 8).
3. In normal winter usage we recommend that the
central heating temperature be set at maximum.
4. Domestic Hot Water: The temperature of the
domestic hot water can be adjusted by turning the
control knob clockwise to increase up to a maximum
of 65° C (Fig. 9).
5. The temperature of the water is also dependent on
the water flow rate and the temperature of the mains
water coming into the house.
6. By slightly reducing the flow from the tap the
temperature will increase up to the maximum if
required.
7. The flow rate can be reduced down to as low as 2.5
litre/min. The boiler will still recognise the need to heat
the water.
