3. INSTALLATION
3.1 General Instructions
BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSON-
NEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL
MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NA-
TIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.
3.2 Place of installation
The boiler must be installed in a special room with ventilation openings towards the out-
side in conformity with current regulations. If there are several burners or extraction units
that can work together in the same room, the ventilation openings must be sized for si-
multaneous operation of all the units. The place of installation must be free of flammable
objects or materials, corrosive gases, volatile substances or dusts which, sucked by the
burner fan, can obstruct the pipes inside the burner or the combustion head. The room
must be dry and not exposed to rain, snow or frost.
AIf the unit is enclosed in a cabinet or mounted alongside, a space must be pro-
vided for removing the casing and for normal maintenance operations. In par-
ticular, after boiler installation with burner on the front door, make sure the front
door can open freely without the burner striking walls or other obstacles.
3.3 Plumbing connections
The heating capacity of the unit must be previously established by calculating the build-
ing's heat requirement according to the current regulations. The system must be provid-
ed with all the components for correct and regular operation. It is advisable to install
shutoff valves between the boiler and heating system allowing the boiler to be isolated
from the system if necessary.
BThe safety valve outlet must be connected to a funnel or collection pipe to pre-
vent water spurting onto the floor in case of overpressure in the heating circuit.
Otherwise, if the discharge valve cuts in and floods the room, the boiler manu-
facturer cannot be held liable.
Do not use the water system pipes to earth electrical appliances.
Before installation, carefully wash all the pipes of the system to remove any residuals or
impurities that could affect proper operation of the unit.
Carry out the relevant connections according to the diagram in and thecap. 5 symbols
given on the unit.
Water system characteristics
In the presence of water harder than 25° Fr (1°F = 10ppm CaCO3), use suitably treated
water in order to avoid possible scaling in the boiler. Treatment must not reduce the hard-
ness to values below 15°F (Decree 236/88 for uses of water intended for human con-
sumption). Treatment of the water used is indispensable in case of very large systems
or with frequent introduction of replenishing water in the system.
BIf water softeners are installed at the boiler cold water inlet, make sure not to
reduce the water hardness too much, as this could cause early deterioration of
the magnesium anode in the hot water tank.
Antifreeze system, antifreeze fluids, additives and inhibitors
The boiler is equipped with an antifreeze system that turns on the boiler in heating mode
when the system delivery water temperature falls under 6°C. The device will not come
on if the electricity and/or gas supply to the unit are cut off. If it becomes necessary, it is
permissible to use antifreeze fluid, additives and inhibitors only if the manufacturer of
these fluids or additives guarantees they are suitable for this use and cause no damage
to the heat exchanger or other components and/or materials of the boiler unit and sys-
tem. It is prohibited to use generic antifreeze fluid, additives or inhibitors that are not ex-
pressly suited for use in heating systems and compatible with the materials of the boiler
unit and system.
Connection to a storage tank for domestic hot water production
Heating temperature setting Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
DHW temperature adjustment Adjustment can be made from the Remote Timer Control menu and the boiler
control panel.
Summer/Winter Switchover Summer mode has priority over a possible Remote Timer Control heating
demand.
Eco/Comfort selection
On disabling DHW from the Remote Timer Control menu, the boiler selects the
Economy mode. In this condition, the
button 7 - fig. 1 on the boiler panel is dis-
abled.
On enabling DHW from the Remote Timer Control menu, the boiler selects the
Comfort mode. In this condition it is possible select one of the two modes with
the
button 7 - fig. 1 on the boiler panel.

The oil burner, with blown air for pressurized furnaces, can be used if its operation char-
acteristics are suitable for the size of the boiler furnace and its overpressure. The choice
of burner must be made beforehand, following the manufacturer's instructions, according
to the work range, fuel consumption and pressures, as well as the length of the combus-
tion chamber. Install the burner according to the Manufacturer's instructions.
AThe electrical power absorbed by the burner must not exceed the value
given in the technical data table.
3.5 Electrical connections
Connection to the electrical grid
BThe unit's electrical safety is only guaranteed when correctly connected to an
efficient earthing system executed according to current safety standards. Have
the efficiency and suitability of the earthing system checked by professionally
qualified personnel. The manufacturer is not responsible for any damage
caused by failure to earth the system. Also make sure that the electrical system
is adequate for the maximum power absorbed by the unit, as specified on the
boiler dataplate.
The boiler is prewired and provided with a Y-cable and plug for connection to the elec-
tricity line. The connections to the grid must be made with a permanent connection and
equipped with a bipolar switch whose contacts have a minimum opening of at least 3
mm, interposing fuses of max. 3A between the boiler and the line. It is important to re-
spect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green
wire) in making connections to the electrical line. During installation or when changing
the power cable, the earth wire must be left 2 cm longer than the others.
BThe user must never change the unit's power cable. If the cable gets damaged,
switch off the unit and have it changed solely by professionally qualified person-
nel. If changing the electric power cable, use solely “HAR H05 VV-F” 3x0.75
mm2 cable with a maximum outside diameter of 8 mm.
Room thermostat (optional)
BIMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE
CONTACTS. CONNECTING 230 V TO THE ROOM THERMOSTAT TERMI-
NALS WILL PERMANENTLY DAMAGE THE ELECTRONIC BOARD.

Allumage de la chaudière
• Ouvrir les vannes d'arrêt du combustible.
• Mettre l'appareil sous tension.
fig. 5 - Allumage de la chaudière
• Pendant les 120 secondes qui suivent, l'afficheur visualise FH (cycle de purge de
l'air du circuit de chauffage).
• Pendant les 5 premières secondes, l'afficheur visualise également la version du lo-
giciel de la carte.
• Dès que l'indication FH disparaît, la chaudière est prête à fonctionner automatique-
ment chaque fois que l'on prélève de l'eau chaude sanitaire ou en présence d'une
demande de la part du thermostat d'ambiance.
Extinction de la chaudière
Appuyer sur la touche on/off (rep. 9 - fig. 1) pendant 1 seconde.
fig. 6 - Extinction de la chaudière
Quand la chaudière est éteinte, la carte électronique est encore alimentée en énergie
électrique.
Le fonctionnement de l'eau chaude sanitaire et du chauffage est désactivé. Le système
hors-gel reste actif.
Pour rallumer la chaudière, appuyer à nouveau sur la touche on/off (rep. 9 fig. 1) pen-
dant 1 seconde.
fig. 7
La chaudière est prête à fonctionner immédiatement chaque fois que l'on prélève de
l'eau chaude sanitaire ou en présence d'une demande de la part du thermostat d'am-
biance.
2.4 Réglages
Commutation Été/Hiver
Appuyer sur la touche été/hiver (rep. 6 - fig. 1) pendant 1 seconde.
fig. 8
L'afficheur montre le symbole Été (rep. 27 - fig. 1) : la chaudière ne fournira que de l'eau
chaude sanitaire. Le système hors-gel reste actif.
Pour désactiver le mode Été, appuyer à nouveau sur la touche été/hiver (rep. 6 - fig. 1)
pendant 1 seconde.
Réglage de la température de chauffage
Pour régler la température entre 30° C (minimum) et 80° C (maximum), agir sur les tou-
ches du chauffage (rep. 3 et 4 - fig. 1).
Toutefois, il est conseillé de ne pas faire fonctionner la chaudière en dessous de
45 °C.
fig. 9
Réglage de la température de l'eau chaude sanitaire
Pour régler la température entre 10 °C (minimum) et 65 °C (maximum), agir sur les tou-
ches eau chaude sanitaire (rep. 1 et 2 - fig. 1).
fig. 10
Régulation de la température ambiante (par thermostat d'ambiance en option)
Programmer à l'aide du thermostat d'ambiance la température souhaitée à l'intérieur des
pièces. Si le thermostat d'ambiance n'est pas monté, la chaudière maintiendra la tem-
pérature dans l'installation à la consigne départ.
Régulation de la température ambiante (par chronocommande à distance en op-
tion)
Programmer à l'aide de la chronocommande à distance la température souhaitée à l'in-
térieur des pièces. La chaudière réglera la température dans le circuit d'eau de l'instal-
lation en fonction de la température ambiante demandée. Pour le fonctionnement par
chronocommande à distance, se reporter au manuel d'utilisation spécifique.
Température évolutive
Lorsqu'une sonde extérieure (option) est installée, l'afficheur du tableau des comman-
des (rep. 5 - fig. 1) montre la température extérieure actuelle mesurée par la sonde. Le
système de régulation de la chaudière travaille en mode "température évolutive". Dans
ce mode, la température d e l'installation chauffage est régulée en fonction des condi-
tions climatiques extérieures de manière à garantir un confort élevé et une économie
d'énergie pendant toute l'année. En particulier, lorsque la température extérieure aug-
mente, la température de départ installation diminue selon une courbe donnée "de com-
pensation.
Avec le réglage évolutif, la température programmée à l'aide des touches chauffage
(rep. 3 et 4 - fig. 1) devient la température maximum de départ installa-
tion. Il est conseillé de régler la valeur maximale pour permettre au système de réguler
la température sur toute la plage utile de fonctionnement.
La chaudière doit être réglée au cours de l'installation par un professionnel qualifié. No-
ter que l'utilisateur pourra faire des adaptations ou ajustements éventuels pour amélio-
rer le confort.
Courbe de compensation et déplacement des courbes
Appuyer une fois sur la touche mode (rep. 10 - fig. 1) pour afficher la courbe de com-
pensation actuelle (fig. 11). Il est possible de la modifier à l'aide des touches eau chau-
de sanitaire (rep. 1 et 2 - fig. 1).
Régler la courbe désirée de 1 à 10, selon la caractéristique (fig. 13).
Si la courbe est réglée sur 0, le réglage de la température évolutive est désactivé.
fig. 11 - Courbe de compensation
Appuyer sur les touches chauffage (rep. 3 et 4 - fig. 1) pour passer au déplacement
parallèle des courbes (fig. 14), qui peut être modifié à l'aide des touches eau chaude
sanitaire (rep. 1 et 2 - fig. 1).
fig. 12 - Déplacement parallèle des courbes
Réappuyer sur la touche mode (rep. 10 - fig. 1) pour quitter le mode de réglage des
courbes parallèles.
Si la température ambiante est inférieure à la valeur désirée, il est conseillé de définir
une courbe supérieure et vice versa. Augmenter ou diminuer d'une unité et vérifier le ré-
sultat dans la pièce ou le local.
