General features.
VICTRIX Zeus is a condensation-type wall-hung room sealed fan-assisted boiler featuring a “Gaudium Magnum” device for fully exploiting the characteristics of this 54 l boiler in
Aisi 316L stainless steel.
There are two versions in the range with working outputs of
23.5 kW (20210 kcal/h) and 31.4 kW (27000 kcal/h) and
both feature an innovative total premix combustion system
that ensures very low pollutant emissions and enables the boiler to run on natural gas and LPG.
The high energy output has been awarded the 4-star mark
(´´´´) in conformity with P.D. 660/96.
The appliance is regulated and controlled by means of a printed microprocessor control board which, through a monitor,
displays the state of boiler operation (temperature, safety devices, etc.) and enables it to be connected (optional) to the Amico Remote Control, to the area unit and to the Multisystem
Water Disconnector.
The hydraulic circuit features a coil water-gas exchanger in
STAINLESS steel, a 3-way electric valve and a 2 l d.h.w.
expansion vessel.
VICTRIX Zeus must be installed using the aspiration/drainage kit or the piping system (Ø 60 mm rigid and Ø 80 mm
flexible) made of plastic material and expressly conceived for
Immergas condensation boilers.

The hot water for heating and domestic use is produced by
a primary and a secondary (d.h.w.) circuit used according to
needs.

Operation.
The heat contained in the products produced by combustion
is absorbed by the pipes of the coil water-gas exchanger fitted
in the condensation module (14) which, in turn, transfers
this to the water circulating inside thanks to the boiler pump
(30).
When the boiler is working for water heating only, water enters the system directly. This depends on the position of the
3-way electric valve (35) which, depending on the type of
request, permits flow through the flow pipe (M) and return
pipe (R) of the system or else deviates flow through the storage tank coil (3).

means of a threaded connecting pieces.
The casing features a threaded union used to directly secure
the automatic release valve (1).
The trend of the curve that represents the flow-head ratio, depends on how the system by-pass is adjusted. Depending on the
position, it provides the system with a higher or smaller head.

(condensation module).
It consists of a casing containing 5 or 6 coil elements (depending on the model).
In turn, each element consists of 5 elliptic pipe spirals.
The whole module is made of stainless steel and the inner part
comprises a sealed combustion chamber and condensation
chamber (2).

The first five elements are involved directly in the action of the
cylindrical burner, fitted to the front, while the sixth is located
in the condensation chamber which is separated from the
combustion chamber by a metal plate (see fumes circuit).
To minimise load losses and increase the flow available for the
system, the delivery consists of the parallel connection of the
first three elements (VICTRIX Zeus 20) or first four elements
(VICTRIX Zeus 27), while the return consists of a parallel
connection of the last two elements.
The exchanger inlet is connected to the pump delivery and the
outlet, on which the NTC heating sensor (1) is positioned, is
connected to the primary circuit delivery.
Connection to the delivery and return pipes of the primary
circuit is of the coupling type with an O ring seal.
The draught diverter (3) is connected at the back by means of
a seal locked by a metal ring.
Condensation is drained from the bottom.

System adjustable by-pass (6).
This ensures water circulation in the primary circuit (between
delivery and return) even when this is prevented by the high

It is mounted on the delivery supply header and it can be
adjusted by means of a screw accessible from the bottom part
of the valve support plate.
System filling unit (5).
This cock is positioned between the boiler circuit and the domestic cold water inlet and makes it possible to pressurise the
heating system.
Downstream of the cock is an one way valve (“2” hydraulic
circuit) that prevents water accidentally passing from the primary circuit to the water mains (d.h.w. circuit).
Its housing is in the bottom part of the enbloc to which it is
screwed.

No-water pressure switch (2).
This reads the pressure difference at the ends of the circulator.
It is housed on the delivery manifold unit (1) and is coupled
to a microswitch (3) that prevents boiler operation when the
pump is blocked or there is no water in the boiler circuit.
This way overheating of the main exchanger is prevented.

It is fitted on the front to the outer side by means of a sockethead screw.
Operation of this valve causes water to exit from the delivery
pipe.

Expansion vessel (8).
Offsets volume changes resulting from water heating thereby
restricting pressure changes.
It has a capacity of 10 l and an 1.0 bar pre-load pressure.
It is located in front of the storage tank in the front section
of the appliance.

Secondary circuit (domestic hot water circuit).
The d.h.w. circuit is engaged every time the temperature of
the water in the storage tank (2) has to be brought to the
desired value. This is measured by means of the d.h.w. NTC
sensor (9).
This can occur both when d.h.w. drawing is run and to make
good losses caused by heat dispersion.
At this stage, the heating function is disengaged because the
production of d.h.w. has priority.
Operation.
Following a d.h.w. request, the modulation board starts the
boiler pump (7) and drives the motor of the 3-way electric
valve (8).
The consequent movement of the valve in d.h.w. position (see
3-way electric valve operation) causes the return pipe (R) to
close and, at the same time, the opening of access towards the
storage tank coil (4).
This way, circulation is prevented in the heating system, while
it is allowed in the coil (4) which, through its walls, permits
the cold water to absorb the heat from the water in the primary circuit.

circuit) to prevent the increase in pressure resulting from
d.h.w heating causing a return towards the water mains.
The storage tank is a coil unit made entirely of AISI 316 L
stainless steel totally insulated with self-extinguishing polystyrene with a working capacity of 54 l.
It consists of an outer jacket enclosed in the bottom part by a
flange secured by 12 screws.
Inside is a cylindrical pipe made of STAINLESS steel shaped
like a concentric spiral (coil) that develops along the entire
height of the storage tank and through the walls of which the
heat exchange occurs between the hot water of the primary
circuit and the water in the storage tank.
This ensures the water in the storage tank is always at a constant temperature and, in the case of a water request, results
in the instantaneous production of d.h.w. (20000 kcal/h or
27000 kcal/h).
If necessary, the coil can be removed from the storage tank
after taking off the lower inspection flange.
Proper operation and integrity are provided by the following
devices:
D.h.w. expansion vessel (11).
Offsets the changes in volume caused by the heating of the
water in the storage tank.
It is connected to the safety valve unit and has a capacity of 2

Gaudium Magnum.
This device is connected between the cold domestic water
inlet (inlet) and the safety valve unit (outlet).
Inside it features a solenoid valve which, in idle condition,
permits the water to flow through a flow limiting device
from 8 l/min (Victrix Zeus 20) or 10 l/min (Victrix Zeus
27) while, when it is operated, it opens a supplementary
passage which is devoid a flow limiting device from 6 l/min
that can higher the water passage of 50%.
Operation.
The valve is enabled electrically (230 VAC) moving the
“Gaudium Magnum” switch on the control panel to
position ( ) and is engaged when the maximum draw limit
thermostat (3), on the storage tank, reads a temperature
over 50 °C.
When the temperature drops below 41 °C, the maximum
draw limit thermostat (3) disables the valve automatically.
This permits drawing a considerable amount of water when
the temperature of the storage tank is high, while when it is
low, the flow of hot water is restricted thereby enabling the
temperature of the d.h.w. to quickly rise again.
By returning the Gaudium Magnum switch to “0” the
valve remains constantly disengaged.
NOTE: to ensure the “Gaudium Magnum” function engages,
the d.h.w. temperature adjustment knob must be in a position
between 6 and 9.

This is a 3-way electric valve operating on the return pipe

request (d.h.w. or central heating), running boiler water into
the central heating system or into the storage tank coil.
This depends on the position of the shutter (3) which impedes
transit towards the system and at the same time permits this
towards the storage tank (d.h.w. position) or vice versa (central
heating position).
Movement of the shutter (3) in both positions is achieved by
energising the motor (1).
by a special system of gears, involves rotation of a disc (6)
fastened eccentrically on the shaft of the motor.
Movement of this disc causes the movement of a special
coupling (5) which, at each 180° rotation, compresses (heating
position) or releases (d.h.w. position) the contrast spring of the
shutter (4).Hydraulic achievement of the required position
causes, alternately, the opening of a limit switch (2) and the
closing of the other.
This permits de-energising the motor and locking this in the
achieved position and enabling motor operation only when a
different request is made (d.h.w. or central heating signal).
Operation.

Air-gas circuit.
Gas valve.
The gas valve features two main coils controlled by the electric
circuit and a pneumatic control unit that modulates the exiting gas pressure at a 1:1 ratio at pressure (P1) detected at the
Venturi pipe inlet.
The ratio between air and gas pressures (off-set) are set on this
valve (see gas regulation).
Electrical coils (4).
Two ON-OFF type coils, powered (230 Vac) by the ignition
unit when the burner has to be ignited.
They are connected in series and energised by mains voltage rectified by means of a diode bridge inside the connector (3).
Pneumatic unit (2).
With this unit the outlet pressure can be varied at a 1:1 ratio
at pressure (P1) detected at the Venturi pipe inlet which is
restored to the valve through a silicone pipe (1).
Thanks to this system, the percentages in the air-gas mix remain
constant at optimum values on the entire modulation field thus
ensuring an almost constant combustion performance.
By loosening the cap, the off-set setscrew can be accessed (2)
by means of which the air-gas ratio can be set.
This is only necessary if, after having analysed the fumes,
incorrect combustion values are found (see air-gas ratio adjustment).
The circuit consists of a total pre-mix combustion system
comprising a fan (5), a pneumatic type gas valve (7), a Venturi
pipe (3) and a special cylindrical burner (8) that works inside
the condensation module.
Operation.
1
The fan (5) is controlled by the modulating control board that
varies speed according to the required output.
Thanks to the fan, combustion air is taken from outside the
sealed chamber and sent through a duct where a Venturi pipe
(3) is installed.
A positive pressure signal (P1) is located at the Venturi (3)
inlet which can be varied in a way directly proportional to the
quantity of air extracted by the fan (5) and which is detected
by means of a pressure point connected to the pneumatic gas
valve (7).
The electrical supply of the main valve coils causes both internal
shutters to open and the gas to flow through, whose outlet
pressure is regulated by the same pneumatic valve with a 1:1
ratio at pressure “P1”.
Through nozzle (4), the gas is injected at the inlet of the Venturi
pipe (3) where pre-mixing begins with the combustion air.
The resulting mix is ignited on the cylindrical burner surface
(8) by a spark from the ignition electrodes (9).

VICTRIX Zeus
Fan.
This operates upstream from the combustion chamber and is
physically positioned at the bottom of the sealed chamber.
It is controlled by the modulating control board with a positive square wave signal with a variable ON-OFF (duty-cycle)
ratio.
Its speed is controlled (from about 1100 to about 5000 rpm)
according to the required output and is controlled by means
of a Hall effect sensor which reads the number of rpm.
The fan extracts the combustion air from the top of the sealed
chamber through a plastic tube (1) that helps reduce noise and
optimises burner ignition.
Variations in the flow of air entering the mixing duct results
in a variation in the pressure (P1) signal at the inlet of the
Venturi pipe and enables the pneumatic valve to regulate
exiting gas pressure.
1
Venturi.
The Venturi pipe (1) is fitted in a sealed duct, inside which the
combustion air and gas are mixed.
The air is driven to the bottom of the duct by the fan, while
the exiting gas from the valve is injected by a nozzle (2) at the
Venturi pipe (1) inlet.
The transit of air in the pipe creates vacuum (“Venturi effect”)
which, through the 4 holes (3) in the base, “drags” the gas
inside and mixes it with the air.
The nozzle (2) differs in diameter according to whether natural
gas or LPG is used; working with both gases at a more or less
constant pressure, its section determines correct gas flow.
At the ends of the Venturi pipe are two pressure points through
which the input (P1) and output (P2) signals are read.
By means of two silicone tubes, these signals are carried,
respectively, to the pneumatic gas valve, which regulates gas
pressure, and to the negative pressure point (P2) located at the
top of the sealed chamber.

This is a cylindrical burner (5) consisting of three concentric

is very resistant to high temperatures and corrosion.
It is fitted inside the condensation module, in a sealed combustion chamber closed by a flange (4) to which the burner is
secured and which ensures direct connection with the air-gas
mix duct (6).
Pre-mixing, the absence of secondary air and the construction
characteristics of the burner ensure high combustion performance and very low pollutant emissions (see technical data and
according to the model).

In this case, in fact, we have a flame-stop condition because
there is no detection by the electrode.
To protect the combustion circuit, this same stoppage prevents
the module from filling with water whenever there are condensation drainage problems (syphon blockage, etc.).

Note: adjustment of the minimum output is done at the same
time as the nominal output setting.
In fact, the modulating control board automatically adjusts fan
speed so as to maintain the modulation range up to a minimum
output of 4000 kcal/h (VICTRIX Zeus 20) and 5298 kcal/h
(VICTRIX Zeus 27).
Air-gas adjustment.
Calibration of the total pre-mix combustion system envisages,
whenever there is the need, adjustment of the nominal heat
output and air-gas ratio (off-set).
With the exception of the nominal output adjustment, which
must nonetheless be done during initial inspection, the two
operations are normally only required after a gas conversion,
after extraordinary maintenance work (replacing a component
part of the air-gas circuit, replacing the modulating control board,
etc.) or when the appliance needs recalibrating.
Air-gas ratio adjustment (off-set).
Correct air-gas ratio adjustment (1:1) is done in the factory
and must be reset only when carbon dioxide (CO2) values
are found in the fumes that do not correspond to optimum
values.
For this purpose, during the initial inspection or after extraordinary maintenance jobs, a fumes analysis must be
performed at maximum output and at minimum output
that certifies combustion complies with the values indicated
in the following table:
Adjusting nominal and minimum heat output.
The availability of maximum output is related to the length
of the suction and exhaust pipes. If this is extended, we have
a slight reduction in the quantity (flow) of air at the inlet and
consequently, also of the pressure of the burnt gas.
The boiler is factory set for operation with a horizontal concentric kit, 60/100Ø, 1 m long, and consequently the use of
flue accessories with higher or lower load losses requires control
and, if necessary, adjustment of the nominal output.

The operation must be performed in the following way and
observing the values given in the output adjustment table:
- connect a differential pressure gauge to pressure points P1
(positive point) and P2 (negative point) located at the top of
the sealed chamber (in this way the pressure difference can be
read at the ends of the Venturi pipe (P1-P2) and a pressure signal
is measured that corresponds to the actual air-gas mix flow to
the burner).
- start the appliance in the chimneysweep mode and set the
heating output trimmer on the modulating control board
to maximum (see modulating control board operation).
- after at least 5 minutes’ operation, adjust the maximum fan
speed adjustment trimmer located on the modulating control board (see modulating control board operation) until you
have a pressure reading (P1-P2) corresponding to nominal
output.
Speed increases by turning clockwise and drops by turning
counter clockwise.

To check correctly and if necessary adjust the air-gas ratio,
proceed as follows:
- start the boiler in the chimneysweep mode and adjust the
heating output trimmer on the modulating control board
at minimum (see modulating control board operation).
- perform a combustion product sampling by inserting the
test probe as far as it will go.
- check to see if the carbon dioxide (CO2) value is within the
limits indicated in the table (previous page).
- if the values are incorrect, restore them to within the limits
by means of the gas valve’s off-set setscrew (3) which can be

the measured carbon dioxide (CO2) reading with that indicated in the table for nominal output (previous page).
The appliance can be adapted to a type of gas different to that
for which the boiler is factory set by using the special kits
(natural gas or LPG).
Transformation involves replacing the gas nozzle positioned at
the inlet of the Venturi pipe and regulating the maximum heat
output (see nominal and minimum heat output adjustment).
Finally, check the carbon dioxide (CO2) value at maximum

Operation.
Draught diverter (1).
Operation of the fan positioned at the inlet of the air-gas mix
duct ensures the forced extraction of the fumes produced by
the cylindrical burner (5).
They directly cover the 4 (VICTRIX Zeus 20) or 5 (VICTRIX
Zeus 27) elements of the primary exchanger fitted in the sealed
combustion chamber (6) on the bottom of which is a steel plate
(7) that separates it from the condensation chamber (2) and
deviates the flow of fumes outside the module.
In this way, the exhaust gases, before entering the condensation chamber (2), cover the 5th (VICTRIX Zeus 20) or 6th
(VICTRIX Zeus 27) element (3) of the exchanger inside which
the primary circuit return water flows.
This cools the products of combustion even more and facilitates condensation before exiting through the draught
diverter (1).
The condensation water that forms inside the exchanger, in
the draught diverter and possibly in the extraction ducts, flows
down to the bottom of the module from where, before being
drained off, it is conveyed to a syphon (4).
This is connected to the back of the condensation module and
conveys the combustion products to the exhaust pipe at the
top of the appliance.
It is involved in the transit of the fumes and the condensation
water that has formed inside or in the exhaust pipes.
It is made of plastic resistant to the corrosive effects of
condensation and is suitable for working at a temperature of
up to 130 ºC (max fumes temperature with 85°C delivery =
78 °C).
Upon the condensation module a fume thermostat (12) is
inserted as safeguard of the draught diverter (1) and intervenes
when the temperature sensed on the condensation module
exceeds 100° C.

Suction and exhaust systems.
(see suction and exhaust terminal instructions).
Fan-assisted sealed chamber configuration
(type C).
Boiler generators with condensation technology must be
installed using the new and specific series of suction and
exhaust pipes conceived for use only with the Immergas
condensation boilers.
The boiler can be installed with a fan-assisted sealed chamber
configuration (type C) or the fan-assisted open chamber configuration (type B23).
The fume fittings of the “GREEN SERIES” are made of plastic
material (PPS =self-extinguishing polypropylene) suitable for
resisting the corrosive action of acid condensation.
Exhaust.
Connection to the exhaust pipes is through a flange (1) or
flanged curve to connect to fitting (2) on the top of the sealed
chamber, placing a specifically shaped seal in between (3).
The flange differs according to whether the system is used split
or concentric.
In the first case, the passage for suction of combustion air (5)
is closed while in the second case it is used.
Fan-assisted open chamber configuration (type
B23) for indoor installation.
Suction.
Using a specific kit, the VICTRIX Zeus boilers can work in
the fan-assisted open chamber configuration (B23) whereby
combustion air is taken directly from the room.
Using the split system, connection to the suction pipes is
exactly the same way as for the exhaust pipes, connecting to
one of the two 80 mm diameter holes (4) at the top of the
sealed chamber.
If coaxial pipes are used, suction occurs by using the concentric
hole outside the exhaust pipe (5).
Suction.
Suction occurs using the hole at the top of the sealed chamber
on which, after having put the relative seal in place (1), the
suction terminal is fitted (2).
The terminal is then secured with the 4 screws (3).
Suction and exhaust kits.
The kits with relative accessories permit use of two concentric
systems, a split system and two specific systems for ducting
(60 Ø rigid or 80 Ø flexible).
As regards the load losses relating to each accessory and the
various possible combinations see the instructions concerning
the suction and exhaust end pieces.
The coupling of the various accessories (curves, extensions, end
pieces) are the slot type and sealing is ensured by EPDM peroxide lip seals resistant to the action of condensation.
Exhaust.
Connection to the 80 mm diameter exhaust pipes is by means
of the flange used for split systems.
By using the relative accessories we can have either a vertical
or horizontal exhaust.
Maximum permitted length (both vertically and horizontally)
is 30 m.

Operating with a room thermostat.
Operation with the Remote Control.
With the main switch (IG) on WINTER it powers the
modulating control board and enables operation in the heating mode.
When the room thermostat contact (TA) closes, the low voltage circuit starts the pump (MP) by means of the K2 relay
contact.
The flow of water intercepts the pump pressure switch (SP)
whose contact, on closing, energises the coil of relay K3.
At the same time, the adjustment circuit causes the relay K1
contact to divert until the 3-way diverter valve (VD) motor (M)
is powered. This motor keeps working until the limit switch
“N” opens when the central heating position is reached.
If the temperature measured by the NTC heating sensor (NR)
is below that set on the control panel with the heating potentiometer, the low voltage circuit starts the fan (MV) and then
closes the contact of the request relay (K3).
Hence the control unit (IGN. BOARD) starts the ignition
cycle, first energising the ignition electrodes (E1-E2) and
then with the possible tripping of the fume thermostat (TF)
both gas valve coils (V/G) after it has been enabled by the
overtemperature thermostat (TS).
Burner ignition is detected by this same control unit (IGN.
BOARD) by way of the ionisation electrode (E3).

With the main switch (IG) on SUMMER, the modulating

If the conditions detected by the Amico Remote Control (CR)
require ignition in the heating phase (CAR SUM/WIN selector
switch on WINTER, heating temperature setting above that detected by the heating sensor (NR), room temperature setting higher
than that read), the board turns the pump (MP) on by means
of relay K2 and ignition occurs as described above.
Note: In both cases, each time the control unit switches off due to
the set temperature having been reached, the modulating control
board turns the burner off in the heating phase for 180 seconds.

If the temperature detected by the NTC d.h.w. sensor (NB) is

During the ignition phase, the fan works at a speed equal to
half the top speed set with the fan speed adjustment trimmer
(FAN POT.).
Once the flame has been detected (signal from the control unit),
speed is changed (modulated) in a way directly proportionate
to the difference between the temperature set with the heating
potentiometer (HEAT) and that read with the heating NTC
sensor (NR) and, if necessary, reaches the maximum set value
in 50 seconds (maximum heating output).
Once the set value is exceeded, the contact of relay K3 opens
and the burner switches off. To restart the burner you have to
wait at least 180 seconds.
The boiler features a microprocessor-controlled electronic
board used both on models with the electric 3-way diverter
valve (VICTRIX Plus, VICTRIX Zeus) and on models with the
hydraulic 3-way diverter valve (VICTRIX).
To have the appropriate operating type, act on jumper R6
(jumper present = electric 3-way diverter valve, jumper
absent = hydraulic 3-way diverter valve).
The board is connected to a socket (DISPLAY BOARD) which,
by means of Leds and a display, shows the boiler operating
status.
Heating request with the Remote Control
Operation.
If the conditions found by the Remote Control (CR) require
operation in the heating phase (SUM/WIN selector switch on
WINTER, time programmer request, room temperature setting
above that found), the low voltage circuit starts the circulator
(MP) by means of relay K2 and powers the 3-way diverter valve
(VD) motor (M) by way of the K1 relay contact.
If the temperature read by the heating NTC sensor (NR) is
below that set with the Remote Control (CR) heating potentiometer, the fan (MV) starts.
Once a speed of 700 rpm is reached (minimum speed for ignition validation) the board closes the contact of the request
relay K3.
This results in the control unit (IGN. BOARD) being powered
and the ignition cycle starting which proceeds in the same way
as the heating request with a room thermostat.
Heating request with a room thermostat.
With the main switch (IG) on WINTER and the room
thermostat contact (TA) closed, the low voltage circuit starts
the circulator (MP) by means of relay K2 and powering the

K1 contact.
If the temperature read by the heating NTC sensor (NR) is
lower than that set with the heating potentiometer (HEAT),
the fan (MV) starts.
On reaching a speed of 700 rpm (minimum speed for ignition
validation) the board closes the contact of the request relay

This results in power reaching the control unit (IGN. BOARD)
and the start of the ignition cycle.

“Chimneysweep” request.
During the ignition phase, the fan works at a speed equivalent
to half the maximum speed set with the fan speed adjustment
trimmer (FAN POT.).
Once the flame is detected, the speed is changed (modulated)
in a way directly proportionate to the difference between the
boiler and room temperatures set and read and, if necessary,
reaches the maximum set value in 50 seconds (heating maximum output).
Once the set value is exceeded, the contact of relay K3 opens
and the burner switches off. To restart the burner, for the same
request, you have to wait at least 180 seconds.
By pressing the reset button (PU1) for at least 10 seconds and
then releasing it, the board enables ignition of the boiler and
keeps it working at maximum power in the heating phase for
15 minutes.
In this phase, only the limit thermostat function is enabled
thanks to the heating sensor (NR) (90ºC for the heating temperature range 25ºC–85ºC and 50ºC for the heating temperature
range 25ºC–45ºC).
The function is indicated by the simultaneous flashing of the
heating Led (DL1) and the d.h.w. Led (DL2) and by the code
“E07” on the CR display (if installed).
It is only engaged if no heating, d.h.w. or antifreeze requests
are in progress.
It can only be interrupted by cutting power to the circuit.
Domestic hot water request.
If the temperature measured by the NTC sensor on the storage
tank (NB) is below the temperature set with the d.h.w. potentiometer (D.H.W.), the low voltage circuit starts the pump
(MP) by means of relay K2 and powers the 3-way diverter valve
(VD) motor (M) by way of the relay K1 contact.
When the pump pressure switch micro (SP) closes, burner
ignition proceeds in the same way as for the heating phase.
Flame modulation takes place with reference to the delivery
temperature detected by the heating sensor (NR) which is
varied according to the difference between the temperature set
with the domestic hot water potentiometer (D.H.W.) and the
temperature measured by the d.h.w. sensor (NB).
When the temperature measured by the d.h.w. sensor (NB)
exceeds the value required, the contact of relay K3 opens,
closing again as soon as the temperature drops.
If, during operation, the heating sensor (NR) measures a
delivery temperature higher than 90ºC, the contact of relay
K3 opens, closing again as soon as the temperature drops to
75ºC.
Heating antifreeze request.
When the temperature measured by the heating NTC sensor (NR) drops below 4ºC, the board enables ignition in
the heating phase and keeps the generator working with the
burner at minimum output until a 35°C boiler temperature
is reached.
Domestic hot water antifreeze request.
If the temperature measured by the d.h.w NTC sensor (NB)
drops below 4ºC, the board enables ignition in the domestic
hot water phase and keeps the generator working with the
burner at minimum output until the d.h.w. sensor (NB)
measures a temperature of 8ºC.
During operation, the water in the primary circuit remains
below 35ºC because when this temperature is reached the
board switches the burner off.

(K2)
This is a unipolar relay that controls the circulator (MP), which is powered when operation is
required.
Request relay
(K3)
3-way diverter valve relay
(K1)
This is a unipolar relay excited when the burner has to be ignited.
By means of its contact, the ignition control unit is energised.
This is a relay for powering the electric 3-way diverter valve motor (VD).
It is excited with a central heating request: It remains idle with a domestic hot water request.
Reset
With this signal the ignition control unit can be released after the overheating safety device and
no-ignition safety device have triggered.
This is done by pressing the reset button PU1 on the boiler control panel or, if mounted, on the
remote control panel (see CR operation).
Fan
It is a positive square-wave signal with variable ON-OFF ratio (duty-cycle) that controls the fan.
It permits varying the flow of air to the Venturi pipe and consequently the pressure of the gas to
the burner.
Adjustements.
Heating potentio. (HEAT.)
Depending on the selected range, the water temperature can be set for central heating between 25ºC
and 85ºC or between 25ºC and 45ºC.
D.h.w. potentio. (D.h.w.)
The domestic hot water temperature can be set between 20°C and 60°C.
Pump selector switch

Heating temperature range
switch
(CM2)
Depending on its position, it enables the heating potentiometer to adjust
the temperature between 25ºC and 85ºC (range 1) or between 25ºC and
45ºC (range 2).
Engaged = Range 1
Not engaged = Range 2
Central heating power
trimmer.
(HEATING POT.)
This trimmer is used to regulating power during the heating phase, adapting it to system requirements (from max set on fan speed trimmer to related minimum).
Fan speed trimmer
(FAN SPEED POT.)
This regulates top fan speed and adapts it to flue accessory requirements in order to use nominal
heat power.
After each adjustment, the minimum speed is automatically adapted so as to maintain the modulation range unaltered (depending on boiler power).

Safety devices.
Circulator antilock
The circulator is started for 60 seconds after:
- 24 hours of inactivity with the SUM/WIN switch on SUMMER
- 3 hours of inactivity with the SUM/WIN switch on WINTER (radiator antifreeze).
Failed ignition lock
If, within 10 seconds from the start of the ignition cycle, the ionisation electrode (E3) fails to detect
the flame on the burner, the control unit (IGN BOARD) sends a signal to the modulating control
board (flame lock). This blocks boiler operation and the alarm is shown on the boiler panel display
with error code 01.
To restore boiler operation it must be reset manually by pressing push button PU1.
Water overtemperature lock
If the water overtemperature thermostat contact opens (primary circuit temperature higher than
100°C), boiler operation is blocked. When this safety device triggers it is shown on the boiler panel
display with error code 02.
Fume overtemperature lock
If the fume overtemperature thermostat contact opens (condensation module external temperature
higher than 100 °C) due to burning impurities settled on the exchanger (soots, oxidations and so on),
the functioning of the boiler will be blocked.
When this safety device triggers it is shown on the boiler panel display with error code 02.
Post-circulation pump
To prevent the water/gas exchanger from overheating, at the end of every heating (opening of the room
thermostat), antifreeze or chimneysweep request, the circulator is kept running for 60 seconds.
Sealed-chamber postventilation
After the burner has been switched off, at the end of any type of request, the combustion chamber
is washed and the fan works for 50 seconds at a speed equal to half the set maximum.
NTC sensor breakage
(NR and NB)
The breakage of the d.h.w. sensor (NB) prevents operation in the d.h.w. phase.
Triggering is indicated by error code 12 on the boiler panel display.
The breakage of the heating sensor (NR) prevents operation in both the heating and d.h.w. modes.
Fan speed safety device
If a fan speed outside safety limits is detected (700-5,700 rpm), the burner is switched off and
prevented from restarting for 7.5 minutes.
If the speed read drops to 500 rpm without the previous safety device triggering, the boiler switches
to “fan stop” and a manual reset is required with button PU1.
