Typical use
Preliminary operations
f Firstly, the knob 12 should be on
the position 8 .
f
Make sure, by the gauge 17 that
the cold-system temperature is al-
ways within 0.5 and 1.5 Bar (opti-
mal: 1÷1.5 Bar) . When the pressure
drops below 0.5 Bar , the boiler
stops working . In this case, open
the system filling cock 18 up to ob-
tain, on the gauge, a value between
1.0 and 1.5 Bar .
The system pressure raises with the temperature: a too high initial cold-system pressure could
lead to water drain from the 3 Bar safety valve after the system heating-up.
f
Make sure that the gas cock 19 is open .
f Make sure that the boiler is electrically supplied: green light 1 blinks .
Boiler activation
f
Rotate the knob 12 on Summer 11 if you want to have only hot water production, or on Win-
ter 9 if you need both room heating and hot water production.
f Opening a hot water cock, the burner ignites and, after a short time (that also depends on the char-
acteristics of the plant externally the boiler) hot water flows from the cock.
f
In Winter mode, consequently a request by the Room thermostat, the burner ignites and the
produced heat is sent, by means of the system vector liquid, to the heating elements of the building.
If, in the mean time, a Domestic Hot Water request takes place, this latter has the priority for the
whole request time. Since the DHW requests are usually limited in time, they generally don't have
any effect on the room heating.
Temperature adjustment
Note: correct adjustment leads to creating the conditions for energy saving.
f Heating system adjustment: by rotating the knob 12 along the scale 10 , the setting of the heating
system temperature is made (the value, during the adjustment, is shown on the display 5 ). Generally,
in the deep cold season and/or with poor building thermal insulation (or if you notice that the burner
stays on for a long time, but the room temperature rises too slowly) prefer higher settings. On the
contrary, if you notice that the room temperature exceeds too much, for thermal inertia, the value
set on the room temperature, it's appropriate to decrease the system temperature.
Note:
if the
Remote Control Kit is installed, see also "Remote Control Kit" on page 39 and the relevant
instruction booklet.
Note: don't make confusion between the heating system temperature
here described, with the
temperature of the room set on the Room Thermostat.
