Starting - up the boiler
•
Open the gas Isolation valve located under the
boiler.
•
Switch on the boiler by placing the ON/OFF
switch (1) in the ON position (see “Control
panel”).
•
The boiler will light automatically (with the
WINTER mode selected and room thermostat
connected).
•
Check that there are no flashing numbers on the
display 8 (see error codes). If code H2O appears
on the display 8 this denotes that there is no
water in the boiler. Consequently, fill the system
as described in section “Filling the system”.
■
“WINTER” mode
To switch boiler operation to “WINTER” mode, press
button 6 (see fig. 1). The boiler will only work for the central heating system. The “WINTER” mode setting of the
boiler is signalled by the symbol
lit continuously on the control panel.
The automatic ignition system will light the burner every time there is a demand for room heating. In this case, the
symbol
on the control panel will flash.
■
Regulating the heating temperature
The heating temperature is regulated by knob 2 (see fig.1).
•
Rotating the knob anticlockwise reduces the temperature.
•
Rotating the knob clockwise increases the temperature.
•
The range of temperature settings for the central heating runs from a minimum of 30°C to a maximum of 80°C,
or, in the case of low temperature operation, from a minimum of 25°C to a maximum of 59°C.
