4.4 Alarm records
The "ALARM RECORDS" function starts automatically once the display has been
on for 2 hours, or immediately by setting the P1 parameter to 1.
The records include all the latest alarms, up to a maximum of 5 alarms, and they
are displayed in sequence by pushing and releasing the P1 button on the di-
splay board. If the records are empty (P0=0) or if tracking the same is disabled
(P1=0), the display function is not available.
Alarms are displayed in reverse order compared to the order in which they oc-
curred: this means that the last alarm generated is the fi rst to be displayed. To
delete the alarms records, simply set parameter P0 to 0.
NOTE: To get to the P1 button the cover on the control panel must be removed
and the display board must be identifi ed (fi g. 29).
PROGRAMMING PARAMETERS
Functioning of the display can be personalised by programming three parame-
ters:
Parameter Default
Deletion of alarms records
P0 0
(0 = records empty / 1 = records not empty)
Immediate activation of alarm record manage-
ment
P1 0
(0 = delayed records management activated / 1 =
immediate records management activated
P2 0 Do not change
When button P1 on the display (fi g. 29) is held down for at least 10 sec, the pro-
gramming procedure is activated. The three parameters, with their respective
values, are shown in rotation on the display (fi g. 30). To edit a parameter value,
simply push the P1 button again when the required parameter is displayed, and
then hold it down until the value switches from 0 to 1 or vice-versa (approx. 2
sec).
The programming procedure is closed automatically after 5 minutes, or if there
is an electrical power failure
4.5 Boiler confi guration
There is a series of jumpers (JPX) available on the electronic board which enable
the boiler to be confi gured.
To access the board, proceed as follows:
- turn off the main switch on the system
- loosen the fi xing screws on the housing, move the base of the housing
forwards and then upwards to unhook it from the chassis
- undo the fi xing screws (E) from the instrument panel (fi g. 11)
- loosen the screws (F - fi g. 13) to remove the cover of the terminal board
(230V)
JP1 Calibration
JP2 Do not use
JP3 Calibration (see paragraph on "Adjustments")
JP4 Do not use
JP5 Jumper must be inserted
JP6 Do not use
JP7 Do not use
JP8 Jumper must be inserted
The boiler foresees jumpers JP5 and JP8 inserted as standard
4.6 Adjustments
The boiler has already been adjusted by the manufacturer during production. If
the adjustments need to be made again, for example after extraordinary main-
tenance, replacement of the gas valve, or conversion to another gas, observe
the following procedures.
The adjustment of the maximum and minimum output, and of the maximum
and minimum heating and of slow switch-on, must be made strictly in the se-
quence indicated, and only by qualifi ed personnel only:
- disconnect the boiler from the power supply
- move the function selector to the Service Area and turn it fully clockwise (fi g.
26)
- loosen the fi xing screws (E) on the instrument panel (fi g. 11)
- lift then turn the instrument panel towards you
- loosen the fi xing screws on the cover (F) to access the terminal board (fi g. 13)
- insert the jumpers JP1 and JP3 (fi g. 32)
- power up the boiler
The three LEDs on the instrument panel fl ash simultaneously and the display
shows "ADJ" for approximately 4 seconds
Next change the following parameters:
Description
1 - Absolute maximum
2 - Minimum
3 - Heating maximum
4 - Slow switch-on
as follows:
- turn the heating water temperature selector to set the required value
- press the CO button (fi g. 23) and then skip to the calibration of the next para-
meter.
Live electrical parts (230 V AC).
The following icons light up on the monitor:
1. during absolute maximum calibration
2. during minimum calibration
3. during heating maximum calibration
4. during slow switch-on calibration
End the procedure by removing jumpers JP1 and JP3 to store these set values
in the memory.
The function can be ended at any time without storing the set values in the me-
mory and retaining the original values as follows:
- remove jumpers JP1 and JP3 before all 4 parameters have been set
- set the function selector to
- cut the power supply 15 minutes after it is connected.
Calibration can be carried out without powering up the boiler.
By turning the function knob, the monitor automatically shows the
number of rotations, expressed in hundreds (e.g. 25 = 2,500 rpm).
The function for visualizing the setting parameters is activated by the function
selector in ON position, by pressing the CO button on the circuit board, either
with or without request for heat.
This function cannot be activated when connected to a remote control.
Upon activating the function the setting parameters are visualized in the order
given below, each for 2 seconds. Each parameter is displayed together with its
corresponding icon and fan rotation speed measured in hundreds.
1. Absolute Maximum
2. Minimum
3. Max. heating
4. Slow ignition P
5. Max. preset heating
GAS VALVE CALIBRATION
- Connect the boiler to the power supply
- Open the gas tap
- Set the function selector (3 - fi g. 1) to
- Loosen the screws (E - fi g. 11), remove the housing, then lower the instrument
panel towards you
- Loosen the fi xing screws on the cover (F) to access the terminal board (fi g. 13)
- Press the CO button (fi g. 23)
Live electrical parts (230 V AC).
- Wait for burner ignition.
The display shows "ACO" and the yellow LED fl ashes. The boiler operates at
maximum heat output.
The "combustion analysis" function remains active for a limited time (15 min);
if a delivery temperature of 90°C is reached, the burner is switched off . It will
be switched back on when this temperature drops below 78°C.
- Insert the analyser probe in the ports provided in the air distribution box, after
removing the screws from the cover (fi g. 33)
- Press the "combustion analysis" button a second time to reach the number of
rotations corresponding to the maximum domestic hot water output (table
1); the yellow LED continues to fl ash while the red LED is fi xed
- Check the CO2 value: (table 3) if the value does not match the value given in
the table, use the gas valve maximum adjustment screw
- Press the "combustion analysis" button a third time to reach the number of
rotations corresponding to the minimum output (table 2); the yellow LED
continues to fl ash while the green LED is fi xed
- Check the CO2 value: (table 4) if the value does not match the value given in
the table, use the gas valve minimum adjustment screw
- To exit the "combustion analysis" function, turn the control knob
- Remove the fl ue gas probe and refi t the plug
- Close the instrument panel and refi t the housing.
The "combustion analysis" function is automatically deactivated if the board trig-
gers an alarm. In the event of a fault during the combustion analysis cycle, carry
out the reset procedure.
