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.
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 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 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. To simplify the
installation of such a combination, ACV has designed a specific hot water
connection kit, easy to be incorporated inside the casing.
• Prestige excellence :
combines all the advantages of ACV’s
Tank-in-Tank systems with the comfort and space saving of a wall-mounted
boiler: in a 63 cm wide casing, it includes a 62-litre stainless steel Tank-in-
Tank. The Prestige 32 Excellence supplies 258 litres of water at a temperature
of 40°C in 10 minutes: In addition to their exceptional hot water supply
capability, the Prestige Excellence tank-in-tanks feature:
- A solution for scale deposits :
thanks to the specially designed corrugations, the hot water tank expands
and contracts during the heating cycle, preventing the formation of scale.
- A guarantee against the risk of legionnellae Disease and bacteria :
the hot water tank is fully immersed in the primary circuit and the hot
water is constantly kept at a temperature above 60°C.
- exceptional resistance against corrosion and aggression :
provided by the stainless steel.
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.
