1- GENERAL SAFETY DEVICES
The boilers produced in our factory are built with care down
to the last component to protect both the user and installer
from eventual accidents. We therefore recommend qualified
personnel that after working on the product they should pay
particular attention to the wiring, especially the bare wires,
that must not be exposed outside the terminal board for any
rason to prevent any contact with the live parts of the wiring.
This instructions manual is integral parts of the product. Make
sure they remain with the boiler, even if it is transferred to
another owner or user or moved to another heating system.
In case of loss or damage, please contact your local Technical
Assistance Service for a new copy.
This boiler may only be installed and serviced by qualified fit-
ters who satisfy the requirements of local rules. Work must be
done in compliance with regulations in force and subsequent
updates.
The boiler must be serviced at least once a year. This should
be booked in advance with the Technical Assistance Service.
The installer shall instruct the user in the operation of the boil-
er and the safety devices.
This boiler may only be used for what it was expressly built to
do. The manufacturer declines all contractual and non-con-
tractual liability for injury to persons or animals or damage to
property deriving from errors made during installation, adjust-
ment and servicing and from improper use.
This appliance is used to produce hot water and must there-
fore be connected to a heating and/or a domestic hot water
system, according to its performance and power
After removing the packaging, make sure the contents are
undamaged and complete. If this is not the case, contact your
dealer.
We recommend always being careful to control the degree
of wear of the keep-alive anode during ordinary maintenance
jobs.
The safety valve outlet must be connected to a suitable col-
lection and venting system. The manufacturer declines all li-
ability for any damage caused by the safety valve.
The safety and automatic adjustment devices on the appli-
ance must never be modified during its lifetime, except by the
maker or dealer.
If the appliance develops a fault and/or works badly, switch it
off and do not attempt to repair it yourself.
Immediately after installation, inform the user that:
- in the event of leaks, he/she must shut off the water supply
and promptly inform the Technical Assistance Service
- he/she must check from time to time to make sure the
symbol is not lit on the control panel. This symbol means
that the pressure in the water system is incorrect. If neces-
sary, fill the system as described in the paragraph “Boiler
functions”
- if the boiler is not planned to be used for a long period, he/
she should call in the Technical Assistance Service to per-
form the following operations:
- turn off the main boiler and general system switches
- close the gas and water taps on both the heating and do-
mestic hot water circuits
- drain the heating and domestic hot water circuits to prevent
freezing.
Connect the outlet collector to a suitable outlet system (refer
to chapter 6).
Safety measures:
the boiler should not be used by children or unassisted disa-
bled people
electrical devices or equipment, such as switches, applianc-
es, etc., should not be used if there is a smell of gas or fumes.
If there is a gas leak, open all the doors and windows to venti-
late the area, turn off the general gas tap and immediately call
the Technical Assistance Service

2- BOILER INSTALLATION
Boiler must only be installed by qualified personnel in compliance
with current legislation. Boiler is available in the following models:
Model Type Category Power
B.S.I. Combined C 25 kW - 35 kW
Exclusive Boiler Green HE B.S.I. is a C-type condensation wall-
mounted boiler for heating and producing domestic hot water,
supplied with a 60 litres inox water tank. Class C appliances can
be installed in any kind of room as long as the fumes discharge
and the comburent air intake are taken outside the room. The fol-
lowing types of fumes outlet are available for this kind of boiler:
B23P; B53P; C13,C13x; C23; C33,C33x; C43,C43x; C53,C53x;
C63,C63x; C83,C83x; C93,C93x. Installation must comply with lo-
cal standards and regulations in force.
For proper installation, we remind you that:
- the boiler must not be installed over a kitchen or any other cook-
ing equipment
- it is forbidden to leave inflammable substances in the room
- suitably insulate heat-sensitive walls (e.g.: in wood)
- minimum spaces are to be left in order to allow maintenance
operations: at least 2,5 cm every side and 20 cm under the boiler.
Keep the distance of 370 mm from the bottom of the boiler
to the furniture casing: there must be sufficient space for
dismantling operations if the magnesium anode has to be
cleaned.
Support plate and integrated pre-installation template are provided
for with the boiler (fig. 2).
Mounting instructions:
- fix the boiler support plate (F) with the template (G) to the wall
and use a plumb to check that it is perfectly horizontal
- trace out 4 holes (ø 6 mm) for fixing the boiler support plate (F)
and 2 holes (ø 4 mm) for fixing the preinstallation template (G)
- make sure all the measurements are correct, then drill holes in
the wall using a drill and point with the diameter given previously
- fix the plate to the wall by the supplied anchor screws
- make hydraulic connections.

4- CLEANING THE SYSTEMAND CHARACTERISTICS
OF HEATING CIRCUI T WATER
After installing a new system or replacing a boiler, clean the heat-
ing system.
To ensure the product works correctly, after cleaning, additivating
and/or chemically treating the system (e.g.: anti-freeze, film-form-
ers, etc.), make sure the characteristics of the water satisfy the
parameters indicated in the table.
Parameters um Water in heating
circuit
Inlet water
PH 7 ÷ 8 -
Hardness ° F - 15 ÷20
Appearance - limpid
5- INSTALLING THE EXTERNAL PROBE
Install the probe (fig. 4) in an area of smooth wall; for brick walls
or other irregular surfaces, prepare a smooth contact area if at all
possible.
Remove the upper plastic cover by turning it anti-clockwise.
Identify the wall fixing point and drill a hole for the 5x25 expansion
grip. Insert the expansion grip into the hole. Remove the card from
its housing. Fix the housing to the wall using the supplied screw.
Attach the bracket and tighten the screw. Loosen the cable grom-
met screw, push in the probe connection cable and connect it to the
electrical terminal. Remember to firmly secure the cable grommet
to prevent humidity from entering. Put the card back into its hous-
ing. Close the upper plastic cover by turning it clockwise. Firmly
secure the cable grommet.
Installing and connecting up the external sensor
The sensor must be installed on an external wall of the building
you want to heat, while taking care to comply with the instructions
below:
- It must be fitted on the facade most often exposed to wind, on a
wall facing NORTH or NORTH-WEST, and taking care to avoid
direct sunlight.
- It must be fitted about 2/3 up the height of the façade.
- It must not be near any doors, windows, outlets for air ducts, or
near chimneys or other heat sources.
The electrical connection to the external sensor must be formed
using a two-pole cable (not supplied), with a cross-section of 0,5
to 1 mm2 and a maximum length of 30 metres. It is not necessary
to worry about the polarity of the cable for the connection to the
external sensor. Do not form joints in this cable. If a joint has to be
made it must be watertight and adequately protected.
Any conduiting used for the connection cable must be sepa-
rate from the conduits used for the power cables (230 Vac).
6- CONDENSATE COLLECTION
The outlet collector (A, fig. 5) collects: the condensate water, any
evacuation water from the safety valve and the system outlet water.
The collector must be connected, by means of a rubber pipe,
to a suitable collection and evacuation system in the storm
water outlet and in compliance with current regulations.
The external diameter of the collector is 20 mm: we therefore
suggest using an Ø18-19 mm pipe, to be closed with a suit-
able clamp (not supplied).
The manufacturer is not responsible for any damage caused
by the lack of a collection system.
The outlet connection line must have a guaranteed seal.
The manufacturer of the boiler is not responsible for any
flooding caused by interventions of the safety valve.
7- GAS CONNECTION
Before connecting appliance to gas pipe network, check the fol-
lowing:
- regulations in force are met
- gas type used is the same as set for appliance operation
- pipes are clean.
After installation make sure that all the joints have been made
airtight conforming to standard installation practices.
Gas must be piped externally. If the pipe goes through a wall it must
go through the central opening in the lower part of the template. It
is recommended to install an appropriately sized filter on the gas
line in case gas from the mains contains some small solid particles.
8- ELECTRIC CONNECTION
To access the electrical connections, proceed as follows:
- loosen the fixing screws (A) and remove the shell (fig. 3)
- lift up the panel and turn it forwards
- open the terminal board covers making them slide in the direc-
tion of the arrows (fig. 6: Bhigh voltage connections 230 V, Clow
voltage connections).
Connect the appliance to the mains electricity supply with a switch
featuring a distance of at least 3,5 mm (EN 60335-1, category III)
between each wire. The appliance uses alternating current at 230
Volt/50 Hz, has a power input of 66W (25 B.S.I.) - 116W (35 B.S.I.)
and complies with EN 60335-1. The appliance must be connected
to an efficient earth circuit, according to current legislation and by-
laws.
Live and neutral (L-N) connections should also be respected.
The boiler can operate with phase-neutral or phase-phase power
supply. For floating power supply, without an earth-bonded conduc-
tor, it is necessary to use an insulation transformer with secondary
anchored to ground.
The earth conductor must be a couple of cm longer than the
others.
Gas and/or water pipes may not be used to earth electrical
equipment.
The installer is responsible for making sure that the appliance
has an adequate earthing system; the manufacturer shall not
be held liable for eventual damages caused by incorrect us-
age or failing to earth the boiler.
Use the supplied power cable to connect the boiler to the mains
power supply.
Connect the ambient thermostat and/or time clock as shown in the
electrical diagram.
When replacing the power cable, use a HAR H05V2V2-F cable,
3 x 0,75 mm2, Ø max. external 7 mm.
9- FILLING THE SYSTEMS, ELIMINATING THE
AIR AND EMPTYING THE SYSTEMS
The systems can be filled up once the water mains have been con-
nected up.
This must be done while the installation is cold by:
DHW system (fig. 7)
- open the cold water stopcock (H) to fill up the water tank
- open the hot water to check the water tank filled up and wait until
the water discharge
Heating system (fig. 7)
- making sure that the drain valve (B) is closed
- giving two or three turns to the cap of the automatic air vent valve
(C) to open it
- opening the filling stopcock (I) until the pressure measured by
the hydrometer (D) is about 1,5 bar (blue zone)
- open the manual vent valve (E) and close it again once the sys-
tem has been vented; if necessary, repeat this operation until no
more air leaves the valve (E)
- close the filling stopcock (I)
- each time the electricity supply to the boiler is switched on, an
automatic vent cycle lasting about 2 minutes starts, and the dis-
play reads “SF”, and the “functions selectors” light up in se-
quence. Press the button to interrupt the automatic vent-
ing cycle.
NOTE: air extraction from the boiler takes place automatically,
through two automatic bleeding valves, Cand F.
NOTE: the boiler is also equipped with a semi-automatic filling sys-
tem. The first system-filling operation must be carried out by open-
ing tap Iwith the boiler turned off.
CH system emptying (fig. 7)
Before starting to empty it, remove the electrical feeder by position-
ing the general switch for the system on “off”.

7
EXCLUSIVE BOILER GREEN HE B.S.I.
- Close the interception devices for the thermal system
- Open the automatic air vent valve (C)
- Unscrew the drain valve (B) by hand, keeping the elbow on the
hose in position to prevent it coming out of its seating
- The water from the system is discharged through the outlet col-
lector (A)
- Emptying out the lowest parts of the system.
DHW system emptying (fig. 7)
The hot water system must be emptied every time there is risk of
freezing by:
- turning off the stopcock at the mains
- unscrew the cap on the hose adapter (G)
- connect a plastic hose to the hose adapter of the storage boiler
drain valve (G)
- open the valve drain device
- turning on all the hot and cold taps
- emptying out the lowest parts of the system.
ATTENTION
The collector must be connected, by means of a rubber pipe, to a
suitable collection and evacuation system in the storm water outlet
and in compliance with current regulations. The external diameter
of the collector is 20 mm: we therefore suggest using an Ø18-19
mm pipe, to be closed with a suitable clamp (not supplied). The
manufacturer is not responsible for any damage caused by the lack
of a collection system.
Suggestions to correctly eliminate air from the heating system
and boiler (Fig. 8)
We recommend carrying out the sequence of operations given be-
low during first installation or with extraordinary maintenance work:
1. Using a CH11 spanner open the manual air vent valve located
above the air box; the tube supplied with the boiler must be con-
nected to the valve to let out the water into an outside container.
2. Open the manual system filling stopcock on the water group,
wait until the water starts coming out of the valve;
3. Switch on the boiler leaving the gas cock closed;
4. Use the room thermostat or the remote control panel to activate
request for heat so that the three-way will turn to heating;
5. Activate request for hot water as follows:
instant boilers: turn on a tap for 30” every minute so that the
three-way cycles from heating to domestic hot water and vice
versa about ten times (here the boiler will go into alarm as it
lacks gas and has to be reset every time this happens).
Heating only boilers connected to an external water tank:
use the water tank thermostat;
6. Continue the sequence until water only comes out of the manual
air vent valve and the flow of air has finished; close the manual
air vent valve at this point;
7. Make sure the system is at the correct pressure (1 bar is ideal);
8. Close the manual system filling stopcock on the water group;
9. Open the gas cock and ignite the boiler.
10- FUMES EXHAUSTION AND BURNING AIR
SUCTION
EXHAUSTION CONFIGURATIONS (fig. 9)
Boiler is homologated for the following exhaustion configurations:
B23P-B53P Suction in room and discharge outside
C13-C13x Concentric wall exhaustion. Pipes can separately start
from boiler, but outlets must be concentric or close enough to be
subject to similar wind conditions (within 50 cm).
C23-C23x Concentric exhaustion in common chimney (suction and
exhaustion in the same chimney).
C33-C33x Concentric roof exhaustion. Outlets like C13.
C43-C43x Exhaustion and suction in common separate chimneys,
but subject to similar wind conditions.
C53-C53x Wall or roof separate exhaustion and suction in different
pressure areas. Exhaustion and suction must never be located on
opposite walls.
C63-C63x Exhaustion and suction with separately certified and
sold pipes (1856/1).
C83-C83x Single or common chimney exhaustion and wall suction.
C93-C93x Discharge on roof (similar to C33) and air suction from a
single existing smoke pipe
Refer to regulations in force for exhaustion of combustion products.
Boiler is provided for without fume exhaustion/air suction kit, since
forced draught sealed chamber accessories can be used, as they
better adapt to installation characteristics. For fume extraction and
burning air restoration in boiler, use original pipes or other EC-cer-
tified pipes with equivalent characteristics; check connection is cor-
rect as shown on instructions fume accessories provided for with.
More appliances can be connected to a single chimney, provided

Switching on
Switch on the boiler as follows:
- access the gas tap through the slots in the cover located in the
lower part of the boiler
- open the gas tap by turning it anti-clockwise (fig. 16)
- power the boiler.
Each time the power supply is switched on the boiler carries out
an automatic venting cycle that lasts about 2 minutes. The display
reads “SF” (fig. 17) and the “function selectors” light up in
sequence. Press the button to interrupt the automatic
venting cycle.
If the check is concluded correctly, once the automatic venting cycle
has been completed the boiler is ready to work.
The boiler turns on in the status it was in before it was switched
off: if the boiler was in the winter mode when it was switched
off, it will turn on again in the winter mode. If it was in the OFF
mode, the display will show two segments in the central area
(fig. 18). Press the button to enable operation.
Choose the desired operating mode by pressing button,
until the symbol moves to:

Adjusting heating water temperature
Turning the selector A(fig. 21), after having positioned the selector
mode on winter , it is possible to regulate the heating water
temperature.
Turn clockwise to increase the temperature and anticlockwise to
decrease. The bar segments light up (every 5°C) as the temperature
is increased. The selected temperature value appears on the display.
Adjusting heating water temperature with an external sensor
connected
When an external probe is connected, the value of the delivery
temperature is automatically chosen by the system which rapidly
adjusts ambient temperature to the changes in external temperature.
Just the central segment of the bar is illuminated (fig. 22).
To increase or decrease the temperature with respect to the value
automatically calculated by the electronic board, turn the heating
water selector clockwise to increase and anticlockwise to decrease.
The bar segments light up (at every comfort level), correction toler-
ance lies between - 5 and + 5 comfort levels (fig. 22). When choosing
the level of comfort, the digit area of the display shows the required
level of comfort while the bar shows the matching segment (fig. 23).
Adjusting domestic hot water temperature
To adjust domestic hot water temperature storaged in the water
tank, turn switch B(fig. 24) clockwise to increase and anticlock-
wise to decrease. The bar segments light up (every 3°C) as the
temperature is increased.
The selected temperature value appears on the display.
When choosing the temperature, both for heating and domestic
hot water, the display shows the value being selected.. About 4
seconds after the selection has been made, the modification is
memorised and the display returns to the delivery temperature
read by the probe..

Working the boiler
Adjust the ambient thermostat to the required temperature (approx.
20 °C). If there is a demand for heating water, the boiler starts
and the symbol is shown on the display (fig. 25). The boiler
will remain working until the set temperatures are reached, after
which it will go on stand-by. In the event of ignition or operating
faults, the boiler will perform a “safety stop”.
The flame symbol will go out and the fault code and will
be displayed (fig. 26). For a description of faults and how to reset
them, consult chapter “Troubleshooting”.
Switching off
Switching off for short periods
For brief absences press the button to switch off the boiler. The
display will show two segments in the central area (fig. 27). When
the boiler remains powered with the gas tap open, it is protected
by the following systems:
- anti-freeze: when the temperature of the water in the boiler
falls below safety values, the circulator and the burner work
at minimum power to increase the water temperature to a safe
value (35 °C). The symbol lights up on the display (fig. 27).
- circulator anti-block: one operating cycle is performed every
24 hours.
Switching off for long periods
For prolonged absences press the button to switch off the boiler
(fig. 27). The display will show two segments in the central area.
Turn the main switch to “off”.
Turn off the gas tap under the boiler by turning it clockwise (fig. 28).
In this case, the anti-freeze and anti-block systems are disa-
bled.
Empty the water circuit or suitably protect it with a good make
of anti-freeze. Drain the domestic hot water circuit.

Semi-automatic filling
The boiler features a semi-automatic filling device which turns on
by pressing the button when the corresponding symbol is
shown on the display (fig. 29).
If this condition occurs it means that the system is incorrectly pres-
surised though the boiler will continue to work regularly. Press the
circuit filling button to start-up the filling sequence.
Press the circuit filling button a second time to interrupt the
filling sequence. During filling, the drops of the circuit filling symbol
and the growing pressure value appear on the display in a
cascade sequence (fig. 30).
After filling, the symbol is displayed for a few moments and
then turns off.
Note
During filling, the boiler does not perform other functions. For
example, if there is a request for domestic hot water, the boiler is
unable to provide it until filling has finished.
Note
If circuit pressure reaches 0.6 bar, the pressure value flashes
on the display (fig. 31a); if it falls below a minimum safety value
(0.3 bar), fault code 41 appears on the display (fig. 31b) for a
certain time, following which, if the fault persists, fault code 40
is displayed (see chapter on “Troubleshooting”).
In the event of fault 40, press to reset and then to start filling
the circuit. After correcting fault 40, the boiler runs an automatic
vent cycle lasting about 2 minutes; the display reads “SF” (fig.
32) and the “function selectors” light up in sequence. Press
the button to interrupt the automatic venting cycle. If
you have to fill the system several times, contact the Technical
Service Centre to check whether the heating circuit is watertight
(see if there are any leaks).

Troubleshooting
When a fault appears on the display, the flame symbol goes
out, a flashing code is shown and the two symbols and
appear either together or separately.
For a description of the faults, consult the following table.
(D) Permanent
(T) Temporary. In this operating status the boiler attempts to eliminate the fault on its own
(°) See NOTE in the next page.
(*) If these two errors occur, check the pressure indicated on the water gauge. If the pressure is insufficient (< 0,4 bar, red area), proceed with the filling
operations described in the chapter “Filling and emptying the systems”.
If the system’s pressure is sufficient (> 0,6 bar, blue area) the malfunction is caused by a lack of water circulation. Contact the Technical Assistance.

Resetting faults
Wait for about 10 seconds before resetting operating conditions.
Then proceed as follows:
1) Viewing just the symbol
If disappears, it means that an operating fault has been
discovered which the boiler is attempting to solve on its own
(temporary stoppage). If the boiler does not resume normal op-
eration, two things may happen:
case A (fig. 39)
disappears, the symbol and a different alarm code
appear. In this case, proceed as described in point 2.
case B (fig. 40)
and a different alarm code are displayed together with .
In this case, proceed as described in point 3.
case C - alarm 91 (Call the technical assistance service)
The boiler has a self-diagnosis system which, on the basis of the
hours totalised in particular operating conditions, signals the need
for maintenance or cleaning of the primary exchanger (alarm code
91). After cleaning using the kit supplied as an accessory, reset the
hour counter as follows:
- disconnect the mains power supply
- remove the screws and hooks securing the electrical cover
- remove connector J13 (see wiring diagram)
- power the boiler and wait for alarm 13 to appear on the display
- disconnect the power supply and reconnect connector J13
- put back the electrical cover and restart the boiler
N.B.: perform the counter reset procedure every time the primary
exchanger is thoroughly cleaned or replaced.
2) Viewing just the symbol (fig. 41)
Press the button to reset the appliance. If the boiler starts
the ignition phase and resumes normal operation, it may have
stopped by accident.
If these stoppages should continue, contact the Technical As-
sistance Centre.
3) Viewing the and symbols (fig. 42)
Contact the Technical Assistance Centre.
Note
Fault in domestic hot water circuit sensor - 60: the boiler
works regularly but does not ensure the stability of the hot water
temperature which, however, is delivered at a temperature of
approximately 50°C. The fault code is only displayed in standby.

This boiler incorporates a new generation of electronic boards that,
by setting/modifying operating parameters, allow the boiler to be
personalised to satisfy various system and/or user requirements.
The programmable parameters are shown in the table on the next
page.
The parameters must be programmed with the boiler in the
OFF position. To do this, press the button until the display
shows “- -” (fig. 43).
During parameter modification operations, the “select functions”
button acts as an ENTER (confirm) button, the button acts as
an ESCAPE (escape) button. If no confirmation is given within
10 seconds, the value is discarded and returns to the previously
set one.
Setting the password
Press and hold down the select functions button and the button
together for about 10 seconds. The display will look like fig. 44.
Enter the password for accessing the parameter modifications
function by turning the domestic hot water temperature selector
to obtain the required value. The password for accessing the
parameter programming function is located on the back side of the
control panel. Confirm by pressing ENTER.
Modifying parameters
Turn the domestic hot water temperature selector (fig. 45) to
sequentially scroll the two-figure codes of the parameters indicated
in the table. After identifying the parameter you wish to modify,
proceed as follows:
- press ENTER to access the parameter modification function.
When ENTER is pressed, the previously set value starts flashing
(fig. 46)
- turn the domestic hot water temperature selector to change the
value
- press ENTER to confirm the new value. The digits stop flashing
- press ESCAPE to exit.
The boiler returns to the “- -” (OFF) status.
To reset, press the button (fig. 43).

PARAMETER 03. Type of building
In order to calculate delivery temperature, the temperature control
system does not directly use the external temperature value
but considers the heat insulation of the building: in well-lagged
buildings, external temperature variations affect the ambient
temperature less than they do in badly-lagged buildings. Use
parameter 3 to set the heat insulation level of the building according
to the following scheme:
value read by the probe may very well be higher then that measured
by a reference probe.
Enable and optimise the THERMOREGULATION function by setting
the following parameters:

PARAMETERS 21 and 22. Maximum and minimum delivery
temperature
These two parameters limit the delivery temperature automatically
produced by the TEMPERATURE CONTROLfunction. PARAMETER
21 determines MAXIMUM DELIVERY TEMPERATURE (MAXIMUM
HEATING SET POINT) while PARAMETER 22 determines
MINIMUM DELIVERY TEMPERATURE (MINIMUM HEATING SET
POINT).
PARAMETER 45. Choosing the offset temperature curve (graph 1)
The offset heating curve maintains a theoretical ambient
temperature of 20°C at external temperatures ranging from +20°C
to -20°C. The choice of the curve depends on the rated minimum
external temperature (on the geographical area, therefore) and the
rated delivery temperature (on the type of system, therefore) and
must be carefully calculated by the fitter using the following formula:
PARAMETER 44. Enable thermoregulation function
The connected external temperature probe combined with
PARAMETER 44 provides the following operating modes:
EXTERNAL PROBE CONNECTED and PARAMETER 44 = 0 (OFF)
in this case the TEMPERATURE CONTROL function is disabled
even though the external probe is connected. The temperature read
by the external probe can always be viewed by pressing the INFO
button. The TEMPERATURE CONTROL symbols are not displayed.
EXTERNAL PROBE CONNECTED, PARAMETER 44 = 1 (ON) in
this case the TEMPERATURE CONTROL function is enabled. The
temperature read by the external probe and the TEMPERATURE
CONTROL symbols can be viewed by pressing the INFO button.
The TEMPERATURE CONTROL function cannot be enabled
unless the external probe has been fitted and connected. In
this case, PARAMETER 44 is ignored and has no effect on
boiler operation.
If, from your calculations, you obtain an intermediate value between
two curves, we suggest choosing the compensation curve closest
to the value obtained.
Example: if the value obtained from the calculations is 8, this is
between curve 7.5 and curve 10. In this case, choose the closest
curve, which is 7.5.

P. 45 = 10 x 20- rated min. external T
PARAMETER 51. Type of heat request
IF AN AMBIENT THERMOSTAT IS CONNECTED TO THE
BOILER, SET PARAMETER 51 = 0 (graph 2).
The ambient thermostat makes a heat request when its contact
closes, while it stops it when its contact opens. Though delivery
temperature is automatically calculated by the boiler, the user may
manually override it. By modifying HEATING on the user interface,
the HEATING SET POINT will no longer be available but just a
value that can be set from +5 to -5°C as required. Modifications to
this value do not directly change delivery temperature but affect the
calculation made to automatically determine its value by modifying
the reference temperature of the system (0 = 20°C).

CONNECT AT/BT
In case of using CONNECTAT/BT, accessory supplied on request,
the boiler gives the possibility to choose 2 thermoregulation curves:
- OTC 1 CH (parameter 45) for a direct system
- OTC 2 CH (parameter 47) for a mixed system.
Even in case of second circuit (2CH) the curve depends on the
external minimum project temperature (on the geographical area,
therefore) and on the delivey project temperature (on the type of
system, therefore); the installer must to put attention to calculate
it using the following formula:
Parameters 31 and 32 give the possibility to define the maximum
and the minimum central heating set-point of the second circuit.
To correct the curve in this configuration, please refer to the
instructions supplied with the accessory.

IF A PROGRAMMABLE TIMER IS CONNECTED TO THE
BOILER, SET PARAMETER 51 = 1 (graph 3).
When the contact is closed, the heat request is made by the
delivery probe on the basis of the external temperature in order
to maintain the rated ambient temperature at the DAY level (20
°C). When the contact opens, it does not stop the heat request but
reduces (parallel shift) the temperature curve to the NIGHT level
(16 °C). Though delivery temperature is automatically calculated
by the boiler, the user may manually override it.
By modifying HEATING on the user interface, the HEATING SET
POINT will no longer be available but just a value that can be set
from +5 to –5°C as required.
Modifications to this value do not directly change delivery
temperature but affect the calculation made to automatically
determine its value by modifying the reference temperature of the
system (0 = 20 °C for DAY level; 16 °C for NIGHT level).
