The system pressure raises with the temperature: a too high inial cold-system pressure could
lead to water drain from the 3 Bar safety valve aer the system heang-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 acvaon
f Rotate the knob 12 on Summer 11 if you want to have only hot water producon, or on Win-
ter
9 if you need both room heang and hot water producon.
f Opening a hot water cock, the burner ignites and, aer a short me (that also depends on the char-
acteriscs of the plant externally the boiler) hot water ows 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 heang elements of the building.
If, in the mean me, a Domesc Hot Water request takes place, this laer has the priority for the
whole request me. Since the DHW requests are usually limited in me, they generally don't have
any eect on the room heang.
Temperature adjustment
Note: correct adjustment leads to creang the condions for energy saving.

10, the seng of the heang
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 insulaon (or if you noce that the burner
stays on for a long me, but the room temperature rises too slowly) prefer higher sengs. On the
contrary, if you noce that the room temperature exceeds too much, for thermal inera, 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
instrucon booklet.
Note: don't make confusion between the heang system temperature
here described, with the
temperature of the room set on the Room Thermostat.
