descrIptIon of the technIcal
specIfIcatIons
The
Prestige
is a wall-hung condensing boiler meeting the
requirements of current
“HR-Top”
standards in Belgium. The boiler
is certified compliant with
“EC”
standards as a connected
appliance:
C13(x) - C33(x) - C33s - C43(x) - C53 - C83(x)
, but it
can also be connected as an open appliance in category
B23
or as an appliance of category
B23P
, which can operate with
a positive pressure.
housIng
The boiler is enclosed in a steel housing, which has been treated
with a degreasing and phosphatizing process, then spray painted
and baked at 220°C. The inside of this housing is lined with a
layer of thermal and sound insulation, which minimizes losses.
heat exchanger
The core of the
Prestige
features a new stainless steel heat
exchanger that is the fruit of exhaustive research and intensive
laboratory testing. This exchanger reflects ACV’s 80 years of
experience in using stainless steel for heating and hot water
generation systems. The special shape of the heat exchanger is
calculated to obtain a very high Reynolds number throughout all
its cycles. The
Prestige
thus achieves an exceptional output that
remains stable throughout the boiler’s life, given that it causes no
oxidation on the exchanger, which is manufactured entirely from
high-quality steel.
Burner
ACV uses its BG 2000-M burner for the
Prestige
: this is a
modulating air/gas premix burner providing safe and quiet
operation while limiting emissions (NOx and CO) to an incredibly low
level. Although the ACV BG 2000-M burner is very modern, it uses
proven technology and is manufactured using standard spare parts
that are easily available on the market.
temperature control
The basic version of the
Prestige
is fitted with a regulator
controlled by an MCBA microprocessor [Micro-Controlled Boiler
Automate), which handles the safety functions (ignition, flame
monitoring, temperature limitation, etc,) and the temperature
control of the boiler. This MCBA also features a regulator
governed by outdoor weather conditions. Simply connect the
outdoor temperature sensor, available as an option.
However, this regulator can also operate with a standard room
thermostat (on/off). Combining this regulator with a room
thermostat provides temperature control governed by outdoor
weather conditions, with indoor compensation.
The user may access four parameters to adjust all the necessary
settings. By entering a specific maintenance code into the unit,
qualified installers may access certain parameters, in order to
adapt the boiler to special requirements. In principle, these are
factory preset for all normal applications.
hot Water generatIon
• It is specially designed to operate only as a heater or in
combination with the whole range of ACV water tanks. The
Smart Line range is the number one choice for domestic or
commercial applications.
frost protectIon
The boiler features a built-in frost protection mechanism: as soon
as the flow temperature [NTC1 probe] drops below 7°C, the central
heating pump is activated. As soon as the flow temperature is at
3°C, the burner starts up until the flow temperature rises above
10°C. The pump continues to run for around 10 minutes.
If an outdoor temperature probe is connected, the pump is
activated when the outside temperature drops below the preset
threshold.
In order to enable the Prestige boiler to protect the whole system
against freezing, all the valves of the radiators and the convectors
should be completely open.
