by rotang the knob 13 along the
scale
14, the seng of the hot
water produced by the boiler, is
made (the value, during the adjust-
ment, is shown on the display 5).
On this type of boiler, we suggest to
set the knob in such a way to have
a comfortable hot water tempera-
ture by drawing only hot water or
eventually by mixing it with a lile
cold water. Avoid maximum values
if not strictly needed, that will force
to mix the hot water with bigger
quanes of cold water. Consider that, because of the dispersions along the pipings, a certain me
is needed to have a stable water temperature on the cock outlet, therefore the best temperature
evaluaon is achieved during a bath or a shower.

The burner doesn’t turn on
f if the room thermostat (or programmable room thermostat, or similar) is installed, check that it is
really requiring the room heang;
f check that the electrical power supply is present and that the Summer/Winter
knob isn't posi-
oned on
(stand-by) but on Summer or Winter . The  light should be steadily ON
(see details in the paragraph "The front control panel" on page 7);
f if the RED locking light was on or blinking, or if you noce an anomalous behaviour of the light indi-
cators, see the paragraph "Alarms - boiler block" on page 30;
f check on the gauge that the boiler pressure is correct (1÷1.5 Bar in a cold state) or at least not below
;
f let the technician to look up the notes in the paragraph "Electrical diagram" on page 37.
Shortage of domesc hot water producon
f check that knob is not set on a too low value or to the “service”posion
f call a qualied technician to check gas valve regulaon;
f call a qualied technician to check, and eventually clean, the DHW exchanger.
Remark: where the water hardness value is too high, it is suggested the installaon of a soen-
ing device, in order to prevent the limestone precipitaon; this operaon avoids a frequent
cleaning of the coil.
