With a system water return
temperature of less than 55 degrees,
condensate will be produced, and
the efficiency increased.
1.3.3 Regulation
of the external sensor
If an external sensor is installed, the
value of the output temperature is
automatically chosen by the system,
which quickly adjusts the of flow
temperature on the basis of the
external temperature.
If you wish to change the value
of the temperature, increasing
or decreasing that calculated
automatically by the electronic
card, proceed as indicated in 1.3.2.
The level of various correction of a
value of temperature proportional
calculated. The display will be as
shown.

of the controls. The display will be as
shown in figure (boiler in stand-by).
In this way, leaving the electricity
and the gas supply connected, the
boiler is protected from frost and
from the pump becoming jammed.
If the boiler is not used for a
prolonged period, it is advisable to
disconnect the electricity supply,
by switching off the main switch
of the system, and to close the gas
tap and, if low temperatures are
expected, to completely drain the
hydraulic circuits to avoid pipes
being damaged from frost.
1.4 ERRoRS and SolUtionS
When there is a functioning error,
the display controls shows
a red
lEd. Descriptions of the errors with
the relative alarms and solutions are
given below:
– al 02 (fig. 5)
If the water pressure detected is
lower than 0.5 bar, the boiler will
stop and the display will show
“AL 02”. Using the external filling
device, bring the system pressure
back to normal so that the pressure
indicated by the hydrometer(fig
5) is between 1 and 1.5 bar.
WHEN FILLING HAS BEEN
COMPLETED CLOSE THE
CONNECTIONS OF THE FILLING
LOOP AND DISCONNECT IT.
If it necessary to repeat the system
refilling procedure, it advisable
to contact a qualified technical
personnel to check the seal of the
heating system(to check whether
there are any leaks).
