DESCRIPTION OF THE SPECIFICATIONS
The
HeatMaster
®
TC
is an hot water producer combined in
a condensing boiler in accordance to the Belgium "
HR-Top
"
standard. The boiler is certified compliant with "
CE
" 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
HeatMaster
®
TC
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
HeatMaster
®
TC
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
HeatMaster
®
TC
: 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
HeatMaster
®
TC
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
In addition to its exceptional hot water performances, the
ACV
Tank-in-Tank concept provides the follwoing advantages :
- 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 boiler 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.
