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 display 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
occurred: this means that the last alarm generated is the first to be display-
ed. 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 remo-
ved and the display board must be identified (fig. 36a).

PROGRAMMING PARAMETERS

Functioning of the display can be personalised by programming three pa-
rameters:
Parameter Default
Deletion of alarms records
P0 0
(0 = records empty/1 = records not empty)
Immediate activation of alarm record management
P1 0 (0 = delayed records management activated/
1 = immediate records management activated
P2 0 Do not change
When button P1 on the display (fig. 36a) is held down for at least 10 sec,
the programming procedure is activated. The three parameters, with their
respective values, are shown in rotation on the display (fig. 36b). To edit a
parameter value, simply push the P1 button again when the required para-
meter 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 configuration
There is a series of jumpers (JPX) available on the electronic board which
enable the boiler to be configured.
To access the board, proceed as follows:
- turn off the main switch on the system
- loosen the fixing screws on the housing, move the base of the housing
forwards and then upwards to unhook it from the chassis
- undo the fixing screws (E) from the instrument panel (fig. 14)
- loosen the screws (F - fig. 16) to remove the cover of the terminal board
(230V).

cording to the installation type.
Jumper not inserted - standard installation
Standard installation 40-80°C
Jumper inserted - floor installation
Floor installation 20-45°C.
In the manufacturing phase, the boiler is configured for standard installations.

with external sensor connected)

The boiler foresees jumpers JP5 and JP8 inserted as standard (heating
only version arranged for storage tank with thermostat); if the use of an
exterior storage tank with probe is required, jumper JP8 must be removed.
4.6 Setting the thermoregulation (fig. 43)
The thermoregulation only operates with the external sensor connected;
once installed, connect the external sensor (accessory available on request)
to the special terminals provided on the boiler terminal board (fig. 5).
This enables the THERMOREGULATION function.
Selecting the compensation curve
The compensation curve for heating maintains a theoretical temperature of
20°C indoors, when the external temperature is between +20°C and -20°C.
The choice of the curve depends on the minimum external temperature
envisaged (and therefore on the geographical location), and on the delivery
temperature envisaged (and therefore on the type of system). It is carefully
calculated by the installer on the basis of the following formula:
envisaged delivery T. - Tshift
KT=
20- min. envisaged external T.
Tshift = 30°C standard installations
25°C floor installations
If the calculation produces an intermediate value between two curves, you
are advised to choose the compensation curve nearest the value obtained.
Example: if the value obtained from the calculation is 1,3 this is between
curve 1 and curve 1,5. Choose the nearest curve, i.e. 1,5.
Select the KT using trimmer P3 on the board (see multiwire wiring diagram).
To access P3:
- remove the housing,
- loosen the fixing screw on the instrument panel
- turn the instrument panel towards you
- loosen the fixing screws on the terminal board cover
- unhook the board casing
Live electrical parts.
The KT values which can be set are as follows:
standard installation: 1,0-1,5-2,0-2,5-3,0
floor installation 0,2-0,4-0,6-0,8
and these are displayed for approximately 3 seconds after rotation of the
trimmer P3.
TYPE OF HEAT REQUEST
Boiler connected to room thermostat (JUMPER JP6 not inserted)
The heat request is made by the closure of the room thermostat contact,
while the opening of the contact produces a switch-off. The delivery
temperature is automatically calculated by the boiler, although the user may
modify the boiler settings. Using the interface to modify the HEATING, you
will not have the HEATING SET-POINT value available, but a value that you
can set as preferred between 15 and 25°C. The modification of this value
will not directly modify the delivery temperature, but will automatically affect
the calculation that determines the value of that temperature, altering the
reference temperature in the system (0 = 20°C).
Boiler connected to a programmable timer (JUMPER JP6 inserted)
With the contact closed, the heat request is made by the delivery sensor,
on the basis of the external temperature, to obtain a nominal indoor
temperature on DAY level (20°C). With the contact open, the boiler is not
switched off, but the weather curve is reduced (parallel shift) to NIGHT level
(16°C). This activates the night-time function.
The delivery temperature is automatically calculated by the boiler, although
the user may modify the boiler settings.
Using the interface to modify the HEATING, you will not have the HEATING
SET-POINT value available, but a value that you can set as preferred
between 25 and 15°C. The modification of this value will not directly modify
the delivery temperature, but will automatically affect the calculation that
determines the value of that temperature, altering the reference temperature
in the system (0 = 20°C for DAY level, and 16°C for NIGHT level).
