DESCRIPTION

The EXCLUSIVE boilers have a new ACC (Activate Combustion Control) system. This new control system, developed by Beretta, ensures functionality,

efciency and low emissions under any conditions. The ACC system uses an ionisation sensor immersed in the burner ame,

whose information allows the control board to operate the gas valve that regulates the fuel. This sophisticated control system provides the auto-regulation of the combustion, so there is no need for an initial calibration. The ACC system is able to adapt the boiler to operate with different gas compositions, different

outlet pipes lengths and different altitudes (within the specied design

limits). The ACC system can also perform an auto-diagnostic operation that locks out the burner before the permitted upper emission limit is exceeded.

EXCLUSIVE is a type C condensing wall-hung boiler to be used for heating and the production of domestic hot water: depending on the fume discharge

accessory used, it is classied in categories B23P;B53P; C13,C13x;

C33,C33x; C43,C43x; C53,C53x; C63,C63x; C83, C83x; C93, C93x. In B23P conguration (when installed indoors), the appliance cannot be installed in bedrooms, bathrooms, showers or where there are open

replaces without a proper air ow. The room where the boiler is installed

must have proper ventilation. Detailed requirements for the installation of

the ue, the gas piping and for ventilating the room, can be found in UNI 7129-7131. In conguration C, the appliance can be installed in any type of room (there

are no limitations due to ventilation conditions or room volume).

3 INSTALLATION

3.1 Cleaning the system and characteristics of the water

In the case of a new installation or replacement of the boiler, it is necessary to clean the heating system. To ensure the device works well, top up the additives and/or chemical

treatments (e.g. anti-freeze liquids, lming agents, etc.) and check the

parameters in the table are within the values indicated.

Before installation, wash all system piping carefully in order to remove any residues that may impair the operation of the appliance.

Page 4

EXCLUSIVE

Under the safety valve, install a water collecting funnel with the

corresponding discharge in the event of leaks due to the overpressure of the heating system. The domestic hot water circuit does not need a safety valve, but make sure that the pressure of waterworks does not exceed 6 bar. In case of doubts, install a pressure reducer.

Prior to ignition, make sure that the boiler is designed to operate

with the gas available; this can be checked by the wording on the packaging and by the adhesive label indicating the gas type.

It is very important to highlight that in some cases the ues are under

pressure, so the joints of the various elements must be airtight.

3.2 Installation regulations

The installation must be carried out by qualied personnel, in compliance

with the following reference standards:

- UNI 7129-7131

- CEI 64-8. Always comply with local standards of the Fire Department, the Gas Company and with possible municipal dispositions.

POSITION EXCLUSIVE is a wall-hung boiler for heating and for the production of hot

water. There are two categories, depending on the type of installation:

- B23P-B53P boiler type - forced open installation, with ue gas discharge

pipe and pick-up of combustion air from the installation area. If the boiler is not installed outdoors, the air intake in the installation area is compulsory;

- C13,C13x; C33,C33x; C43,C43x; C53,C53x; C63,C63x; C83,C83x,

C93,C93x type boiler: appliance with airtight chamber, with ue gas

discharge pipe and pick-up of combustion air from outside. It does not require an air intake point in the installation area. This type MUST be installed using concentric pipes, or other types of

discharge designed for condensing boilers with an airtight chamber.

MINIMUM DISTANCES (g. 6-6a)

To ensure access to the boiler for normal maintenance operations, respect the minimum installation clearances envisaged. For correct appliance positioning, bear in mind that:

- it must not be placed above a cooker or other cooking device

- it is forbidden to leave inammable products in the room where the boiler is installed

- heat-sensitive walls (e.g. wooden walls) must be protected with proper insulation.

In case of installation it is ESSENTIAL to provide the necessary space for the introduction of the instrument for the combustion

analysis check. In g. 6a is shown a sample drawing where the

distances between boiler and cabinet/niche were obtained using a

300mm length tool.

Longer lengths of tools require more space.

3.3 Elimination of air from the heating circuit and from the boiler - g. 7

During the initial installation phase, or in the event of extraordinary maintenance, you are advised to perform the following sequence of operations:

1. Open by two or three turns the automatic relief valve cap (A) and leave

it open.

2. Open the system lling tap located on the water unit.

3. Switch on the electricity supply to the boiler, leaving the gas tap turned

off.

4. Activate a heat request via the room thermostat or the remote control

panel, so that the 3-way valve goes into heating mode.

5. Activate a request for DHW as follows: open a tap for 30” per minute so

that the three-way valve cycles from heating to DHW and vice versa for about ten times (in this situation, the boiler will go into alarm due to lack of gas, therefore reset it whenever this is proposed).

6. Continue the sequence until no more air is felt coming from the air vent

valve.

7. Check the system pressure level is correct (the ideal level is 1 bar).

8. Turn off the system lling tap.

9. Turn on the gas tap and ignite the boiler.

3.4 Positioning the wall-mounted boiler and hydraulic connections - g. 8-9

The boiler comes as standard with a boiler support plate. The position and dimension of hydraulic ttings are shown in the detail drawing. For the assembly, proceed as follows:

- fasten the boiler support plate (F) to the wall and use a spirit level to

make sure it is perfectly horizontal

- mark the 4 holes (ø 6 mm) envisaged for securing the boiler support

plate (F)

- make sure that all measurements are exact, then drill the wall using drill tips with the diameters indicated above

- x the plate with the built-in template to the wall

- carry out the hydraulic connections.

3.5 Electrical wiring - g. 10-11

Low voltage connections

Carry out the low voltage connections as follows:

- use the external cable box supplied as standard

- unscrew the xing screws of the cover (V)

- carry out the connections as shown in g. 11

It is recommended to use wires with section not exceeding

0,5mm2.

In case of TA or TBT connection, remove the respective shunts (g. 12).

- close the box with the screws that were previously removed

- press the two tabs on the sides of the box to place it correctly in its housing in the boiler sliding upward within the guide rails

- tighten the safety screw (V1).

If the low voltage electrical connection box is not connected the boiler does not ignite.

High voltage connections

The connection to the mains supply must be made via a separation device

with an omnipolar opening of at least 3.5 mm (EN 60335/1 - category 3). The appliance works with alternating current at 230 Volt/50 Hz, and is in compliance with Standard EN 60335-1.

It is obligatory to make the connection with a safe ground/earth, in compliance with current directives.

It is the responsibility of the installer to provide suitable grounding for the appliance; the manufacturer will not be liable for any damage resulting from an incorrect or absent earth connection.

It is also recommended to uphold the phase-neutral connection (L-N).

The earth conductor must be a couple of cm longer than the others.

The boiler can operate with a phase-neutral or phase-phase supply. For power supplies that are not earthed, it is necessary to use an isolating transformer with earth-anchored secondary. It is forbidden to use gas and/or water pipes to earth electrical appliances.

Use the power cable supplied to connect the boiler to the mains power

supply.

If the power cable has to be replaced, use a HAR H05V2V2-F cable, 3 x

0.75mm2, Ø max external 7 mm.

3.6 Gas connection

The connection of the gas supply must be carried out in compliance with current installation standards. Before carrying out the connection, check that the type of gas is that for which the appliance is set up.

3.7 Removing the casing

To access the components inside, remove the casing as indicated below:

- locate and unscrew the 2 screws (A - g. 13) that x the casing to the boiler

- by leveraging the xing clips (C - g. 13), unhook the lower part of the casing

- lift the casing upwards to release it from the top tabs (B - g. 13), then remove it.

WARNING

The possible damage of the frontal panel involves the replacement of the same.

The noise absorbing panels inside the front and side walls ensure the airtight seal for the air supply duct in the installation environment.

It is therefore ESSENTIAL after the dismantling operations to correctly reposition the components so as not to compromise the boiler’s operation.

3.8 Flue gas exhaust and combustion air suction

To evacuate the combustion products, refer to UNI 7129-7131. Always

comply with local standards of the Fire Department, the Gas Company and with possible municipal dispositions. The release of combustion products is assured by a centrifugal fan and the control board constantly checks that it is operating correctly. It is essential for evacuating fumes and adduction boiler combustion air that only original pipes are used and that the connection is made correctly as shown in the

instructions provided with the ue gas accessories. A single ue can be connected to several appliances provided that every

appliance is the condensing type.

Page 5

ENGLISH

The boiler is a C-type appliance (with airtight chamber), and must therefore

have a safe connection to the ue gas discharge pipe and to the combustion

air suction pipe; these both carry their contents outside, and are essential for the operation of the appliance. Both concentric and twin terminals are available.

“Straight length” means with terminals and joints but without bends.

The boi

ler is supplied without the ue gas outlet/air suction kit, since

it is possible to use the accessories for condensing appliances that better adapt to the installation characteristics (see catalogue).

The maximum lengths of the pipes refer to the ue accessories

available in the catalogue.

It is compulsory to use specic pipes.

The non insulated ue gas outlet pipes are potential sources of

danger.

The use of a longer pipe causes a loss of output of the boiler

Make sure the ue gas discharge pipe is tilted 3° towards the boiler.

As envisaged by current legislation, the boiler is designed to take

in and dispose of ue gas condensate and/or meteoric water condensate deriving from the ue gas discharge system using its

own siphon.

If a condensate relaunch pump is installed, check the technical data (provided by the manufacturer) regarding output, to ensure it operates correctl.

“Forced open” Installation (type B23P/B53P)

In this conguration the boiler is connected to the ø 80 mm ue gases

discharge pipe by means of an adaptor.

- Position the adaptor so that the Ø 60 pipe goes fully into the ue gases

turret of the boiler.

- Once positioned, make sure that the 4 notches (A) on the ange connect

to the groove (B) on the Ø100 of the adaptor.

- Fully tighten the two locking terminals of the ange (C) so the adaptor

itself is restrained.

Concentric pipes (ø 60-100 mm)

- Position the bend so that the Ø 60 pipe goes fully into the ue gases

turret of the boiler.

- Once positioned, make sure that the 4 notches (A) on the ange connect

to the groove (B) on the Ø100 of the bend.

- Fully tighten the two locking terminals of the ange (C) so the bend itself

is restrained.

Twin pipes (ø 80 mm) - see graphs g. 18

The combustion air suction pipe should be selected from the two inputs,

remove the closing plug xed with the screws and x the specic air deector.

- Position the adaptor on the ue gases pipe so that the Ø 60 pipe goes

fully into the ue gases turret of the boiler

- Once positioned, make sure that the 4 notches (A) on the ange connect

to the groove (B) on the Ø100 of the adaptor.

- Fully tighten the two locking terminals of the ange (C) so the adaptor

itself is restrained.

Concentric pipes (ø 80-125 mm)

- Position the adaptor so that the Ø60 pipe goes fully into the ue turret

of the boiler.

- Once positioned, make sure that the 4 notches (A) on the ange connect

to the groove (B) on the Ø100 of the adaptor.

- Fully tighten the two locking terminals of the ange (C) so the adaptor

itself is restrained.

- Then t the Ø 80-125 adaptor kit on the vertical tting.

Twin pipes ø 80 with ducting Ø50 - Ø60 - Ø80 (g. 15a)

Thanks to the boiler characteristics, a ue gas discharge pipe ø 80 can be connected to the ducting ranges Ø50 - Ø60 - Ø80.

For the ducting, you are advised to make a project calculation in order to respect the relevant standards in force.

The table shows the standard congurations allowed.

3.9 Filling the heating system (g. 16)

Note: even if the boiler is tted with a semi-automatic lling device, the

rst lling operation must be carried out by turning the ller tap (B) with the boiler off.

Once the hydraulic connections have been carried out, ll the heating

system. This operation must be carried out when the system is cold,carrying out the following operations:

- open the cap of the lower (A) automatic air vent valve by two or three

turns; to allow a continuous venting of the air, leave the plug of the valve A open

- make sure the cold water inlet tap is open

- open the lling tap (B) until the pressure indicated by the water pressure

gauge is between 1 and 1.5 bar

- re-close the lling tap.

The venting of the boiler takes place automatically via the two automatic vent valve A positioned on the circulator.

3.10 Draining the heating system (g. 16)

Before starting emptying, switch off the electricity supply by turning off the main switch of the system.

- Close the heating system’s valves.

- Connect a hose to the system drain valve (C).

- Manually loosen the system drain valve (C).

3.11 Emptying the domestic hot water system

Whenever there is risk of frost, the domestic hot water system must be emptied in the following way:

- turn off the main water supply tap

- turn on all the hot and cold water taps

- drain the lowest points.

3.12 Circulator settings

Circulator residual discharge head

The boilers is equipped with an already hydraulically and electrically connected circulator, whose useful available performance is indicated in the graphs at page 43. The circulator comes set from the factory with a 6 metre discharge head curve. The boiler is equipped with an anti-blocking system which starts up an

operation cycle after every 24 hours in standby with the mode selector in

any position.

The “antiblocking” function is active only if the boiler is electrically powered.

Operating the circulator without water is strictly forbidden.

If you need to use a different curve you can select the desired level on the circulator.

Below the main characteristics and the ways to set up their desired operation are listed.

3.12.1 User interface

The user interface is made up of a button (A), a two-coloured red / green LED (B) and four yellow LEDs (C) arranged in a row.

The user interface allows the operating performance to be viewed (operating status and alarm status) and it also allows the circulator operating modes to be set. The performance, indicated by the LEDs (B) and (C) is always visible during normal operation of the circulator whereas the settings can be carried out by pressing the button (A).

3.12.2 Operating status indication

When the circulator is in operation the LED (B) is green. The four yellow LEDs (C) indicate the electrical energy consumption (P1) as shown in the following table.

With the circulator powered, press briey on the button (A) to view the active conguration of the circulator. The LEDs indicate the active settings. In this phase no variations can be made to the circulator conguration. Two

seconds after the button (A) has been pressed the user interface returns to the normal operating status display.

3.12.5 Key lock function

The purpose of the key lock function is to prevent accidental modications

to the settings or the improper use of the circulator. When the key lock function is activated, long-pressing the button (A) is prevented. This prevents the user from entering the circulator’s operating modes setting section. Enabling/disabling the key lock function is achieved by pressing the button (A) for more than 10 seconds. During this step all of the LEDs (C) will ash for 1 second.

This icon indicates that the OFF operating status mode has been set. Each ignition request is ignored except for the anti-freeze function. The pump anti-lock, 3-way valve and anti-freeze function remain active.

This icon indicates that WINTER mode has been selected (HEATING function enabled). If a heating request from the main zone is in progress, the icon will be flashing.

This icon indicates that the circuit for domestic hot water production is enabled. When a domestic hot water request is in progress, the icon flashes.

The P at the top of the domestic hot water icon indicates that the boiler preheating function is enabled; the P when flashing indicates that a preheating

request is in progress.

When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in AUTOMATIC mode (the

management of the heating requests follows what has been set with the timer). If the heating function is not enabled during the current time frame, the icon will be crossed out.

When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in MANUAL mode (the

management of the heating requests does not follow what has been set with the programming timing, but it is always active).

OFF This icon indicates that the system (main zone) has been set to off (not active).

The REC10 remote control has the function of machine interface,

displaying the system and providing access to the parameters. The middle of the main screen displays the temperature of the domestic hot water probe, unless there is a heat request is in progress, in this case the delivery temperature of the boiler at that particular time is displayed.

The value expressed in bar refers to the system’s water pressure.

The top of the screen shows the information regarding the current date and time, as well as the outdoor temperature, if available.

On the left and right sides are displayed the icons indicating the status of the system; their meaning is as follows.

Pressing the keys

“up” and “down”

it is possible to choose from among

the following options:

• PLANT: a scrolling message on the display can indicate the temperature

of the domestic hot water probe rather than the flow sensor of the boiler

• STATE (when the SYSTEM SCREEN is selected): to set the status

of the boiler (OFF, SUMMER or WINTER) and, when managed by the

room thermostat, the operating mode of the main area in heating mode

(ON or OFF if the time schedule is disabled, AUTO according to hourly programming, MANUAL or OFF if programming timing is enabled)

• SET: to establish the heating or hot water setpoint value or for activating

preheating

• INFO: to display the value of the system variables

• MENU: to access the system’s configuration menus

The configuration MENU is organised with a multi-level tree structure. With

the “ok” key you can access the selected submenu, with the

5 COMMISSIONING

5.1 Preliminary checks

First ignition is carried out by competent personnel from an authorised Technical Assistance Service Beretta. Before starting up the boiler, check:

- that the data of the supply networks (electricity, water, gas) correspond to the label data

- that the extraction pipes of the ue gases and the air suction pipes are working correctly

- that conditions for regular maintenance are guaranteed if the boiler is placed inside or between items of furniture

- the seal of the fuel adduction system

- that the fuel ow rate corresponds to values required by the boiler

- that the fuel supply system is sized to provide the correct ow rate to the boiler, and that it has all the safety and control devices required by current regulations

- that the circulator rotates freely because, especially after long periods of inactivity, deposits and/or debris can prevent free rotation.

Eventual releasing of the circulator shaft

- Insert a screwdriver in the hole (1) of the circulator.

- Press (a) and turn the n° 2 Phillips screwdriver (b) until the release of the crankshaft.

Perform this operation with extreme caution to avoid damaging the

components.

5.2 Programming the boiler

- Position the system’s master switch to the “on” position.

- If necessary set the TIME and DATE setting the HOURS, MINUTES,

DAY, MONTH and YEAR with the keys “up” and “down”, confirming the selection.

5.2.4 Setting the thermoregulation

Thermoregulation only works with the outdoor temperature sensor connected and active only for the HEATING function; therefore, once installed, connect the outdoor temperature sensor to the specific connections on the boiler terminal board.

This enables the THERMOREGULATION function.

The temperature measured by the outdoor temperature sensor is displayed on the initial page in the top right, alternating with the display of the time. When thermoregulation is enabled (outdoor temperature sensor present), the algorithm for automatically calculating the outlet setpoint depends on the type of heat request. In any case, the thermoregulation algorithm will not directly use the outdoor temperature, but rather a calculated outdoor temperature that takes into account the building’s insulation: in buildings that are well insulated, the outdoor temperature variations will have less impact than those that are

poorly insulated by comparison. Enabling THERMOREGULATION occurs

in the following way:

- access the technical parameters as explained in the section

“4.1 Access

to the technical parameters”

- select THERMOREGULATION with the “up” and “down” keys, confirming the selection.

PARAMETERS

Using the REC10 it is possible to set the value of the following parameters:

BUILDING TYPE

It is indicative of the frequency with which the value of the calculated outdoor temperature for thermoregulation is updated, a low value for this value will be used for buildings that have little insulation.

Setting range: [5min - 20min] Factory setting: [5min]

REACTIVITY EXT SENSOR

It is an indication of the speed with which variations of the measured outdoor temperature affect the calculated outdoor temperature value for thermoregulation, low values indicate high speeds.

Setting range: [0 - 255] Factory setting: [20]

At this point, to change the value of the previous parameters, proceed as described below:

- access the technical parameters as explained in the section

“4.1 Access

to the technical parameters”

- in sequence select THERMOREGULATION and TYPE OF BUILDING

rather than REACTIVITY EXT SENSOR with the “up” and “down” keys, confirming the selection

- set the desired value with the “up” and “down” keys, confirming the

selection.

Note: The value of the calculated outdoor temperature used by the

thermoregulation algorithm is displayed in the INFO menu under T EXT

FOR THERMOREG.

HEAT REQUEST FROM THERMOSTAT or POR (Programmable Timer)

In this case the outlet setpoint depends on the outdoor temperature for

obtaining a reference ambient temperature of 20°C. There are 2 parameters

that compete to calculate the output setpoint:

- slope of the compensation curve (KT)

- offset on the reference ambient temperature.

SELECTING THE COMPENSATION CURVE- fig. 17

The compensation curve for heating maintains a theoretical temperature of

20°C indoors, when the outdoor temperature is between +20°C and -20°C.

The choice of the curve depends on the minimum outdoor 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:

KT = T. outlet envisaged - Tshift

20- min. design external T

Tshift = 30°C standard system 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.

The settable KT values are as follows: standard system: 1.0-3.0 floor system 0.2-0.8.

Using the REC10 it is possible to set the selected thermoregulation curve:

- access the technical parameters as explained in the section

“4.1 Access

to the technical parameters”

- in sequence select THERMOREGULATION and CLIMATIC CURVES

with the “up” and “down” keys, confirming the selection

- select the desired heating zone with the “up” and “down” keys,

confirming the selection

- set the desired climatic curve with the “up” and “down” keys, confirming

the selection.

OFFSET ON THE REFERENCE AMBIENT TEMPERATURE - fig. 17

In any event, the user can indirectly modify the value of the HEATING setpoint inserting an offset on the reference temperature that can vary within the range -5-+5 (offset 0 = 20°C).

NIGHT COMPENSATION - fig. 17

Whenever a programmable timer is connected to the ROOM THERMOSTAT

input, from the TECHNICAL\THERMOREGULATION\CLIMATIC CURVES\ MAIN the NIGHT COMPENSATION function can be enabled.

In this case, when the CONTACT is CLOSED, the heat request is made by the flow sensor, on the basis of the outdoor temperature, to obtain a

nominal ambient temperature on DAY level (20°C).

The opening of the contact does not produce a switch-off, but a reduction (parallel translation) of the climatic curve on NIGHT level (16°C). Also in this case, the user can indirectly modify the value of the HEATING setpoint inserting once again an offset on the reference DAY temperature (20°C) rather than NIGHT (16°C) that can vary within the range [-5 - +5].

5.3 First commissioning

- Position the system’s master switch to the “on” position.

- Open the gas tap to allow fuel to flow.

Page 17

ENGLISH

- Adjust the room thermostat to the desired temperature (~20°C) or, if the system is equipped with a chronothermostat or programmable timer or

REC10 set as an ambient regulator, ensure that the thermostat or timer is “active” and set correctly (~20°C)

- Then set the boiler for WINTER selecting the STATE menu on the REC10 and then BOILER, based on the season and the type of operation selected.

Wait for the burner to ignite. The boiler will operate at maximum heating output and it will be possible to

regulate the combustion.

- Insert the analyser probes in the specific positions on the air distribution

box, after removing screw (A) and cap of the flue gases analysis socket (B).

- Perform the combustion check verifying that the CO2 values correspond to those indicated in the multigas table.

- Once checking completed, remove the analyser probe and close the combustion analysis sockets with appropriate caps and screw.

If the value displayed is different DO NOT OPERATE ANY ADJUSTMENT ON THE GAS VALVE, please contact the Technical

Assistance Centre.

The gas valve DOES NOT requires adjustments and the possible tampering causes a malfunction or failure of the boiler.

When the sweeper function is in progress all the heat requests are inhibited and a scrolling message appears at the foot of the main page of the REC10; green and red LEDs are off.

When the checks are completed:

- set the boiler to “SUMMER” or “WINTER” mode depending on the season

- regulate the heat request temperature values according to the customer’s needs.

IMPORTANT

The sweeper function is active for a time limit of 15 minutes; the burner shuts down if an outlet temperature of 95° C is reached. It will ignite again when the temperature falls below 75° C.

In case of a low temperature system we recommend carrying out

the efciency test by taking hot water setting the boiler STATE to SUMMER, opening the hot water tap to full capacity and setting the

temperature of the domestic hot water to the maximum.

All controls must be carried out exclusively by the Technical Assistance Centre.

While the electrical supply and the fuel supply remain active, the boiler is protected by the systems:

- heating anti-freeze: this function is activated if the temperature

measured by the flow sensor drops below 5°C. A heat request is generated in this phase with the ignition of the burner at minimum output, which is maintained until the outlet water temperature reaches 35° C;

- domestic hot water anti-freeze: the function starts if the temperature

measured by the DHW NTC probe falls below 5°C. A heat request is generated in this phase with the ignition of the burner at minimum output, which is maintained until the outlet water temperature reaches 55° C.

The activation of the ANTI-FREEZE function is indicated by a

scrolling message on the foot of the REC10 display.

- circulator anti-locking: the circulator activates every 24 hours of

stoppage for 30 seconds.

5.18 Switching off for lengthy periods

If the EXCLUSIVE boiler is not used for a long time, the following operations must be carried out:

- set the status of the boiler to OFF

- set the system’s main switch to “off”

- close the fuel and water taps of the heating and domestic hot water system.

5.24 Maintenance

Periodic maintenance is an “obligation” required by law and is essential to the safety, efciency and lifetime of the boiler.

It allows for the reduction of consumption, polluting emissions and keeping the product reliable over time.

Before starting maintenance operations:

- carry out the analysis of the combustion products to check the operating status of the boiler, then cut off the electrical supply setting the system’s main switch to “off”

- turn off the fuel and water taps of the heating and domestic hot water system.

To ensure product characteristics and efciency remain intact and to

comply with prescriptions of current regulations, it is necessary to render the appliance to systematic checks at regular intervals. When carrying out maintenance work, observe the instructions given in chapter

“1 WARNINGS

AND SAFETY”

This normally means the following tasks:

- removing any oxidation from the burner

- removing any scale from the heat exchangers;

- removing/changing electrodes. When replacing the electrodes it is necessary to replace also the relative sealing gasket.

- checking and cleaning the drainage pipes;

- checking the external appearance of the boiler

- checking the ignition, switch-off and operation of the appliance, in both domestic water mode and heating mode

- checking the seal on the gas and water couplings and pipes

- checking the gas consumption at maximum and minimum output;

- checking the position of the ignition-flame detection glowplug

- checking the gas failure safety device.

After carrying out the maintenance operations the analysis of the combustion products needs to be carried out to make sure it is operating correctly.

In case where, after the replacement of the electronic board or the maintenance of the detection electrode or the burner, the combustion analysis would restore out of tolerance values, it may be necessary to

take action on the parameter COMBUSTION OFFSET as described

in the section

“5.23 Parameters combustion check”

Do not clean the appliance or its parts with inammable substances

(e.g. petrol, alcohol, etc.).

Do not clean panels, painted parts and plastic parts with paint thinner. Panel cleaning must be carried out only with soapy water.

USER GUIDE

Depending on the type of application, some of the functions described in this manual might not be available.

6 CONTROL PANEL REC10

The REC10 remote control unit has the function of a machine

interface, as it displays the system’s settings and allows the parameters to be accessed. It is also capable of providing multi-zone control and weekly room thermostat functionality.

While the system may be equipped with multiple REC10 units,

ONLY ONE serves as the machine’s interface (MASTER). The other

REC10 units serve as a chronothermostat for regulating the ambient

temperatures of the zones with which they are associated; in this

latter case, the main screen of the REC10 shows the environmental

data of the zone to which it is related. The REC10 unit features a backlit liquid crystal display.

This icon indicates that WINTER mode has been selected (HEATING function enabled). If a heating request from the main zone is in progress, the icon will be flashing.

This icon indicates that the circuit for domestic hot water production is enabled. When a domestic hot water request is in progress, the icon

flashes. The P at the top of the domestic hot water icon indicates that the boiler preheating function is enabled; the P when flashing indicates

that a preheating request is in progress.

When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in AUTOMATIC mode (the

management of the heating requests follows what has been set with the timer). If the heating function is not enabled during the current time frame, the icon will be crossed out.

When the “central heating programming timing” is enabled this icon indicates that the system heating (main zone) is in MANUAL mode (the

management of the heating requests does not follow what has been set with the programming timing, but it is always active).

OFF

This icon indicates that the system (main zone) has been set to off (not active).

This icon indicates that the system is detecting the presence of a flame.

This icon indicates the presence of an anomaly, and is always flashing.

Note:

The temperature of the hot water probe is shown at the centre of the main screen. The value’s meaning is indicated at the bottom of the display.

Whenever a heating request is in progress, the value displayed at the centre of the screen refers to the system’s ow sensor, with the relative indication.

The value expressed in bar refers to the system’s water pressure.

The top of the screen shows the current date and time, as well as the outdoor temperature, if available.

On the left and right sides are displayed the icons indicating the status of the system, their meaning is the following:

For fault E041

If the pressure drops below the safety threshold of 0.3 bar the boiler displays the fault code “E041 - WATER TRANSDUCER PRESS OK TO FILL THE SYSTEM” for a transitional time of 10 min during which it is possible to start the semi-automatic loading procedure, pressing the “ok” key to ll the system (the procedure can only be started in SUMMER or WINTER).

E041

WATER TRANSDUCER

PRESS OK TO LOAD THE PLANT

During the loading phase the scrolling message “SEMI-AUTOMATIC FILLING IN PROGRESS” is displayed at the foot of the screen, while the

pressure highlighted on the display should start to rise.

When the loading is nished the scrolling message “SEMI-AUTOMATIC

FILLING FINISHED” is displayed at the foot of the page.

When the transitional time has nished, if the fault persists the fault code E040 is displayed.

When the boiler has fault E040 manual loading should be carried out using the ller tap (A) until the pressure is between 1 and 1.5 bar.

If the pressure drops frequently, contact the Technical Assistance Centre.

For fault E091

The boiler has an auto-diagnostic system which, based on the total number of hours in certain operating conditions, can signal the need to clean the primary heat exchanger. The intervention of the Technical Assistance Centre is necessary.

LIMIT THERMOSTAT

PRESS OK RESET

At this point, if the correct operating conditions have been restored, the boiler will restart automatically. If the attempts to reset the fault do not restore the boiler’s functionality, please contact your local Customer Support Service.

Up to a maximum of 5 reset attempts can be made using the REC10, after

which the machine must be disconnected from the power supply to reset the number of attempts available.

Request the intervention of the Technical Assistance Centre.
