1 BOILER IGNITION (fig. 1)
ENG
Open the gas cock and position the index of
FR
the selector knob in the following positions:
• With the rotary switch in the summer
position ( ), the boiler will start-up
upon demand for domestic hot water,
and will start to modulate in automatical-
ly to reach the selected temperature.
The gas feeding pressure will then auto-
matically vary to ensure that the requi-
red temperature is kept constant.
• With the rotary switch in the winter
position ( ), once the boiler has rea-
ched the value set on the heating poten-
tiometer, it will start to modulate in auto-
matically in order to supply the required
power output to the system.
The operation of the boiler will be stop-
ped through the intervention of the room
4
thermostat or the programable thermo-
stat.
ATTENTION: no noise is produced when
you position the index of the knob on the
desired setting.
2 TEMPERATURES ADJUSTMENT
(fig. 2)
1. The D.H.W. temperature can be adju-
sted by turning the knob of the D.H.W.
potentiometer which has a range of
between 30 to 60°C (86-140° F) .
2. The C.H. temperature can be adjusted by
turning the knob of the C.H. potentiome-
ter which has a range of between 30
to 80°C (86-176° F)
3. To ensure optimal boiler efficiency at all
times, we recommend not to drop below

a minimum working temperature of 50°C
(122° F).
3 TURNING THE BOILER OFF
(fig. 1)
When the selector is in OFF position, the
boiler is in standby, the green LED flashes
at intervals of five seconds and all featu-
res are disabled, except the pump anti-
blocking feature. Move the bipolar switch
to "OFF" to disconnect the unit from the
power supply.
If the boiler is not going to be used for a
lengthy period it is advised to turn off the
electricity supply, close the gas cock, and if
low temperatures are foreseen, empty the
boiler and the hydraulic system to avoid
breakage in the tubes due to the freezing of
the water.
