DESCRIPTION OF THE SPECIFICATIONS
The
Prestige
is a wall-mounted condensing boiler meeting the
requirements of the
“HR-Top”
applicable standards applicable in
Belgium. The boiler is certified compliant with EC standards as a
connected appliance:
C13(x) - C33(x) - C43(x) - C53 - C83(x)
,
but it can also be connected as an open appliance in category
B23
.
LINING
The boiler is protected by a steel lining that first of all undergoes a
degreasing and phosphation process before being lacquered and
heated at 220°C. The inside of this lining is coated with a layer of
thermal and acoustic insulation, reducing losses to a minimum.
HEAT EXCHANGER
The core of the
Prestige
features a new stainless steel heat
exchanger. This piece of technology represents the fruit of
exhaustive research and intensive laboratory testing. It reflects
ACV’s eighty years of experience in using stainless steel for
heating and hot water functions. The particular geometry of the
exchanger pipes is calculated to obtain a very large Reynolds
number throughout its cycles.
The
Prestige
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 quality
stainless steel.
BURNER
ACV uses its BG 2000-M burner for the
Prestige
: this is an
air/gas premix burner providing safe and silent operation while
limiting emissions (NOx and CO) to an incredibly low level. Although
the ACV BG 2000-M boiler is very modern, it uses proven
technology and is manufactured from standard spare parts that
are easily available on the market..
TEMPERATURE REGULATION
The basic version of the Prestige is fitted with a microprocessor
controlled regulator (MCBA) which takes over both the safety
functions (ignition, monitoring the flame, limiting the temperature,
etc.) and control of the boiler temperature.
This MCBA also includes a weather-dependent regulator. All you
need to do is connect the outdoor temperature sensor available
as an option to the device. However, this regulator can also
operate with a standard on/off room thermostat In addition,
with the combination of a weather-dependent regulator and a
room thermostat, you can control the temperatures based on
the weather with compensation for the indoor temperature.
There are four user adjustable parameters. By entering a
special maintenance code, qualified installers can access
several other parameters to adapt the boiler to special
requirements. In principle, these parameters are factory set
for all normal applications.
PRODUCTION OF HOT WATER
• Prestige 50 / 75 Solo :
is custom-designed to operate for
heating only or in combination with the whole range of ACV
water tanks. The SmartLine range is the number one choice
for domestic applications.
FROST PROTECTION
The boiler is equipped with an integrated frost protection: as
soon as the NTC1 flow temperature drops below 7°C, the system
activates the central heating pump. As soon as the NTC1 flow
temperature drops below 3°C, the system automatically ignites
the burner until the temperature rises above 10°C. The pump
continues to run for about 10 minutes.
If an outdoor temperature sensor is connected to the system,
the pump is activated as soon as the outside temperature drops
below the specified threshold.
To provide efficient protection for the whole system against frost,
all the valves on the radiators and the convectors should be
completely open.
