USEFUL TIPS

3.1 Filling the heating circuit

Figure 3.1
Press keys 12 and 14 together to access the
"INFO" (information) menu. The index value
"J00" will be shown on the display in alterna-
tion with the pressure value "b13" (1.3 bar). The
number indicating the pressure is displayed
without a decimal point, and the letter indi-
cates the unit of measure (bar) (Figure 3.2).
Figure 3.2
Open the filling cock in Figure 3.1 located un-
der the boiler also check the heating circuit
pressure on the display. The pressure must be
between 1 bar and 1.5 bar (e.g. 1.3 bar in Figure
3.2).
When the operation is complete, reclose the
filling cock and bleed any air from the radiators.

USEFUL TIPS

3.2 Heating

For rational and economic service, have an am-
bient thermostat installed.
Never turn off the radiator in the room where
the ambient thermostat is installed.
cLOSED
If a radiator (or convector) does not heat, check
if there is air in the system and that its cock is
open.
If the ambient temperature is too high, do not
adjust the radiator cocks but decrease the heat-
ing temperature regulation using the ambient
thermostat or the heating regulation keys 13
and 14 (Figure 3.3).

3.3 Antifreeze protection

The antifreeze system, and any additional pro-
tections, protect the boiler from possible dam-
age due to freezing.
This system does not guarantee protection for
the entire hydraulic system.
If the external temperature could reach values
below 0°C it is recommended to leave the en-
tire system on, setting the ambient thermostat
to a low temperature.
The antifreeze function is also active when the
boiler is in stand-by (the dashes are turned on
in sequence to simulate flowing) (Figure 3.4).
