GAS

G.P.L.

Management of 2 zones with 2
thermostats

KONe is also synonimous of flexibility
of installation. Ideal for all the
installations, thanks to the electronics
that allows to manage 2 zones at
different heating temperature (high for
radiators and fan-coils, low for floor
heating) checking them with on-off or
modulating thermostats

Over-run circulation of 15 seconds

to avoid overheating: it checks in every
condition the thermal equilibrium
between flow and return, also after
intense D.H.W. drawings, while, in
heating mode, with a duration of 5
minutes, allows to dissipate the whole
residual thermal inertia

Operation in sliding temperature

for the maximum economy of
management

Multigas Operation
(Natural Gas or LPG)

with automatic commutation

P

LUS

Antifreeze protection that

intervenes at 5°C and is activated both
in DHW production and heating mode,
increasing the boiler temperature at
15°C. This avoids the risk that KON
can freeze if low temperatures persist
where it is installed. If there is a lack of
gas a lockout signalling will be shown
on the display.

Pump anti-jamming function

also after long inactivity periods. The
electronics of KON put the pump
in operation for 5 seconds every 24
hours of standstill, so avoiding that the
oxidation could stop it

Chimney sweeper function

facilitates the operations of combustion
adjustment. By depressing the reset
button for more than 5 seconds, the
operation of the boiler at minimum or
at maximum capacity for 15 minutes
can be obtained so that the combustion
can be analyzed.

The Details of KON e.

Modulating premix burner

Mixer and fan are part of the “U-MIXPRO
System”. The particular streamline of the Mixer
assures an optimal air-gas mixing, by reducing the
suction noise and integrating itself with the high
efficiency modulating fan.
In synthesis the elements of the system are:

the electronic control (that manages the air-gas

combustion ratio)
the gas control (that doses the combustible gas)
the innovative feed-back of combustion

(what monitors constantly the combustion quality)

makes the system immune from:

• possible oxidation of the electrode

• partial loss of isolation capacity of the electrode

due to the normal aging

• great precision in the combustion control

thanks to the elevated dynamism of the flame

ionization signal
“Quick Release” of the complete plate.

The release allows the complete removal of the

combustion system.

The “Flat” type burner assures:

long duration thanks to the low thermal and

mechanical stresses and to the physical inalterability of
the fibre in FeCr alloy .

ideal propagation of the radiation heat thanks to

its chemical-physical structure able to develop a
particularly soft and bright flame

low NOx emissions (class 5 according to EN 297 and

EN 483)

Condensates Collecting Tray with “Quick Release”

Exclusive Heat Exchanger in Al/Si/Mg Alloy

It is realized in a special Aluminium/Silicon/Magnesium
alloy that assures efficiency and resistance. Thanks to the
configuration of the internal heat exchanger, in regime of
condensation high efficiencies are obtained, higher than
107%, that means, for the consumer, great economic saving
and very low environmental impact.

Modulating pump with automatic air vent

It represents the state of the art in the standard of the high
efficiency. In line with the ErP directive 2015, with less than
1W of consumption in stand-by and only 45 W in operation
at maximum speed, thanks to the wide modulation capacity,
according to the room thermostat and to the temperatures detected
by the temperature sensors placed in flow / return connections,
automatically doses the power of the boiler to the demands of the
heating system. Particularly silent and compact, it integrates with
the safety valve, the bypass and the discharge valve.

Electronic gas valve

Being a last generation valve, it further improves the
perfomances of the product in comparison to the
traditional pneumatic valve.

Advantages:

compactness and noiseless operation
wide modulation range: 1:8
low consumption = less than 4 W
massima sicurezza doppio operatore (classe A e B)
nessuna taratura manuale
gestione totalmente elettronica mediante scheda

intelligente

low thermal and mechanical stresses, therefore long

duration, thanks to its inalterability.

For the version

KON

24 C (combi, with instantaneous DHW production)

e

HWS “Hot Water Speed”

The change-over from the heating
to the DHW production mode
normally takes around 6 and
more seconds, depending on the
commutation speed of the priority
device that stops pump and burner.

It happens, in fact, that the
consumer has to wait, under
the shower, with discomfort, the
reactivation of the system.

The new electronics, adopted
in this boiler, performs, on the
contrary, the change “in run”,
with burner and pump always in
operation, decidedly improving the
comfort of the consumer.

Secondary heat exchanger

With 12 plates in stainless steel AISI
316L. The one fitted on the KON
is different from the others for the
low pressure losses, so optimizing
the warm water circulation in the
boiler. His “thermal length”, a
particular physical expression that
characterizes it, makes it particularly
proper for the condensing boilers.

Its “ecological” design is
characterized by a new shape of
the plates that allows to transfer a
greater quantity of heat, exploiting
better the characteristics of the
stainless steel.

Opening of the panel board Removal of condensates siphon

The big job developed by the Unical
planners to aggregate the propulsion
system (modulating fan, gas valve,
smoke evacuation system, developed
with CAD and CNC technology) has
considered priority the suggestions
reached by the market and by the
international service, bringing to
an essential synthesis complex,
where every element can be quickly
assembled and disassembled,
reducing the installation time, but,
mainly, the one for the ordinary and
extraordinary maintenance.

Thanks to the excellent performances,
KONe represents the maximum
expression of the technology in the
domestic condensing boiler sector.

is set to the technological vertex not

KON
only for the performances, but, as we have
seen, also for the service operations, made
more and more simple and fast.

The Unical After Sale Service, besides, is
equipped with an handy computer, with
3” touch-screen, directly connectable to
the boiler, to develop the activity of KON
monitoring. The rich menu of functions
allows the Service:

to the acquire the KONe data for a

computer analysis

to monitor in real-time the operation
parameters of the boiler, also from remote
(from the office or from the handy computer)

to manage the “faults-history” and the
database of the firmware versions. All this
makes it a flexible and essential tool in the
daily Service activities. This is a choice of
Unical to facilitate both, the Service and the
consumer, speeding the intervention time for
the resolution of possible problems.
