13.1 - Check
heating system
pressure
If the pressure inside the heating
circuit falls below 7psi (0,5 bar),
the appliance switches off and
the display “1” as per Figure 13-1,
shows to indicate that it
is necessary to restore the correct
pressure. Open the fi lling cock and
check the pressure on the pressure
gauge “13” of Figure 13-1, it must
reach a pressure of 20 psi (1,5 bar)
and the indication must
disappear; close the fi lling cock.
CAUTION!!!
During normal
operations, the fi lling cock
must always remain in the
closed position.
If, with time, the pressure drops,
restore the correct value. This
operation may have to be repeated
several times during the fi rst month of
operations to remove any air bubbles
present.
13.2 - Overview
The boiler is pre-set with standard
parameters. However, it is possible to
make a number of changes or consult
the parameters by means of using the
“Users’ Menu” (see Section 13.16).
During functioning display “1” of
Figure 13-1, displays the status of the
boiler and display “2” (see Figure 13-
1) shows the value of the parameters.
The various operating statuses are
shown in Section 13.18.
Within the “Users’ Menu” (see Section
13.16) it is possible to check the last
lock-out or error which have occurred.
In addition to the operating modes,
the instrument panel provides
important information on the current
functioning of the boiler, via the
indicators “3”, “4”, “5” and “6” of Figure
13-1. In particular:
- the indicator “3” displays whether the
burner is functioning (on) or whether it
is off (blinking);
- the indicator “4” displays whether
the domestic hot water service is on
or off;
- the indicator “6” displays whether a
heating service request is active (on)
or nor (off).
13.3 - Displays
During normal operations, the
parameters’ display “1” and the
values’ display “2” (see Figure 13-1)
remain permanently on, if the ”Energy
Saving” mode has not be activated
(See Section 13.15).
The parameters which can be
displayed are shown with their
meaning in the table shown in Section
13.18.
