3.1 ADJUSTING ROOM TEMPERATURE
The central heating system must be equipped with a thermostat to control room temperature.
If no room temperature thermostat is installed when the boiler is first started up, room temperature can be controlled using
the control knob (6).
Simply turn the control knob clockwise to increase room temperature or anti-clockwise to decrease it. The electronic
flame modulation system adapts the gas flow to the burner to suit varying heat exchange requirements as the boiler
achieves the set temperature.
3.2 ADJUSTING DOMESTIC HOT WATER TEMPERATURE
The boiler electronically modulates the burner flame according to the setting of the hot water temperature control knob
(7) and the water flow.
The system therefore guarantees that water temperature from the boiler remains constant even when only a small flow is
being drawn off.
To save energy, keep the domestic hot water temperature control knob turned to "--comfort--" (figure 2).
In the winter it will probably be necessary to increase the temperature of the hot water to suit conditions.
