Programming Parameters - Beretta Quadra Green 25 C.S.I Manual De Instalacion Y Uso

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 identifi ed (fi g. 37a).

PROGRAMMING PARAMETERS

Functioning of the display can be personalised by programming three
parameters:
Param. 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 (fi g. 37a) 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 (fi g. 37b). 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. 14)
- loosen the screws (F - fi g. 16) to remove the cover of the terminal board
(230V).
JUMPER JP7 (fi g. 38):
preselection of the most suitable heating temperature adjustment fi eld ac-
cording to the installation type.
Jumper not inserted - standard installation
Standard installation 40-80°C
Jumper inserted - fl oor installation
Floor installation 20-45°C.
In the manufacturing phase, the boiler is confi gured for standard installations.
JP1 Calibration (Range Rated)
JP2 Reset heating timer
JP3 Calibration (see paragraph on "Adjustments")
JP4 Absolute domestic hot water thermostat selector
JP5 Do not use
JP6 Enable night-time compensation function and continuous pump (only
with external sensor connected)
JP7 Enable management of low temperature/standard installations (see
above)
JP8 Do not use
4.6 Setting the thermoregulation (fi g. 44 - graphs 1-2-3)
The thermoregulation only operates with the external sensor connected;
once installed, connect the external sensor (accessory available on re-
quest) to the special terminals provided on the boiler terminal board.
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 fl oor 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 fi xing screw on the instrument panel
- turn the instrument panel towards you
- loosen the fi xing screws on the terminal board cover
- unhook the board casing

Description
The KT values which can be set are as follows:
standard installation: 1,0-1,5-2,0-2,5-3,0
fl oor 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 tem-
perature 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 modifi cation of this value
will not directly modify the delivery temperature, but will automatically aff ect
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 auto-
matically 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 pre-
ferred between 25 and 15°C. The modifi cation of this value will not directly
modify the delivery temperature, but will automatically aff ect the calculation
that determines the value of that temperature, altering the reference tempera-
ture in the system (0 = 20°C for DAY level, and 16°C for NIGHT level).
4.7 Adjustments
The boiler has already been adjusted by the manufacturer during production.
If the adjustments need to be made again, for example after extraordinary
maintenance, replacement of the gas valve, or conversion from methane
gas to LPG, 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 sequence indicated, and
only by qualifi ed personnel only:
- disconnect the boiler from the power supply
- turn the heating water temperature selector to its maximum
- loosen the fi xing screws (E) on the instrument panel (fi g. 14)
- lift then turn the instrument panel towards you
- loosen the fi xing screws on the cover (F) to access the terminal board
(fi g. 16)
- insert the jumpers JP1 and JP3 (fi g. 40)
- 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:
1. Domestic hot water/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 using a small screwdriver included (fi g. 26) and then
skip to the calibration of the next parameter.
Live electrical parts.
The following icons light up on the monitor:
1. during domestic hot water/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 val-
ues in the memory. The function can be ended at any time without storing
the set values in the memory 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 heating selection 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 func-
tion selector in summer and in winter, 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.
