6C 210 ECO 03/02/06 - 300001746-001-E
General description
The C 210 boiler is a gas fired condensing boiler.
It is CE approved under the following number: 0063BL3264.
The cast aluminium-silicium heat exchanger is designed for the
recuperation of the sensible and latent heat in combusted gases.
Furthermore, an integrated, unique air/gas mixing system (IMS) and
a pre-mix bruner offer a considerable reduction in NOx and CO,
which justifies the expression "Clean combustion boiler".
This watertight combustion circuit boiler can be used in a forced flue
version.
The burner and the combustive air inlet fan are very quiet.
Gas and combustive air is supplied via the upper part of the boiler.
Underneath the boiler is a condensates collector in cast aluminium
andasiphonforcondensatesdischarge.Thesiphonislocatedonthe
side, under the combusted gases discharge.
Output may modulate between 10% and 100% depending on the
heating requirement. Furthermore, the boilers are factory-fitted with
an electronic DIEMATIC 3 control panel, which is preset for priority
domestic hot water production and setting according to outside
temperatures.
The standard DIEMATIC 3 control panel enables the independent
regulation of a boiler circuit without a mixer valve and/or with one or
two circuits with a mixer valve (optional).
The DIEMATIC 3 control panel can also be used to programme a
domestic hot water circuit with or without priority, and to programme
an auxiliary circuit.
The regulator also provides antifreeze protection for the installation
and the environment, if the home is empty, for a period that may be
programmed one year in advance and lasting for up to 99 days.
For Switzerland:
SVGW No. 05-036-4
The installation of the boiler must be done in compliance with the
following directives:
- SSIGE regulations - G1 : Gas installation
- VKF requirements (Cantonal Grouping of Insurance Brokers)
- Local and cantonal regulations
The boiler is supplied preset for an operation with H/E-type
natural gas.

2 Operating principle
TheuniqueIMS system(integrated air/gasmixing system) enablesa
perfect air/gas mixture at the fan inlet. When heating is required, the
IMS opens and the fan pre-ventilates. The fan sucks in the
combustionairthroughtheairinletopening,thantheairisthenmixed
in the IMS with the gas from the combined gas valve unit. The
homogenous air/gas mixture is then carried to the burner by the fan.
The output of the boiler is automatically regulated according to the
settings and the temperatures measured by the sensors.
The air/gas mixture is ignited by the ignition/ionisation electrode,
combustion begins, the hot flue gases pass through the cast
aluminium-silicium heat exchanger and reheat the water in the
heating circuit. At a return temperature lower than around 55°C, the
combusted gases cool down to a temperature lower than the dew
point, thus causing the condensation of the water vapour contained
inthefluegases in thelower section oftheheat exchanger. Theheat
given off by this condensation process (latent heat or condensation
heat)istransferredtotheheatingwater.TheC210thusreachesvery
high efficiency values (operating efficiency > 110% at 40°C and
useful efficiency > 109% at 30/40°C). The condensed water is
dischargedvia thesiphon in the lower sectionof theheat exchanger.
The flue gas circuit is reversed in the condensates recuperation tank
and discharged via the flue gas discharge pipe. The combustion air
circulates around the heat exchanger and thus recuperates the
dissipated heat. Losses through the sides of the boiler are therefore
extremely low (<0.3%).
The very efficient microprocessor in the C 210 guarantees totally
reliable operation. This enables the boiler to react to the slightest
problem in the peripheral installation (for example, water circulation,
air supply or other problems). The boiler will therefore remain
operational (no lockout) despite such problems. In the first instance,
it will attempt to modulate as long as possible by adapting to outside
conditions connected to the installation.
The DIEMATIC 3 control panel controls the room temperature in
accordance to the outside temperature by action on the burner.
Heating regulation is controlled by the influence of the regulator on
the burner, the pumps and, if installed, the mixing valve(s).
Connecting a remote control with room sensor or an interactive
remote control CDI 2 also enables self adaptivity of the gradient and
the parallel offset of the heating curve.
The "installation anti-freeze" function is active regardless of the
operating mode. It is triggered as soon as the outdoor temperature
reaches the limiting value preset to +3°C (see paragraph
" Further information on various parameters").
The domestic hot water is regulated by the regulator acting on the
load pump through the DHW sensor. The DHW loop can be made
through the AUXIL auxiliary contact that includes its own
programming.
The DIEMATIC 3 control panel includes the possibility of "anti-
legionnella" protection (see #MISCELLANEOUS, ANTIFREEZ).

Applications
1Introduction
The C 210 boiler can be used on a very broad field of applications.
Whetherintermsoffluegas orgasconnectionsorfrom thehydraulic
pointofview,awidevariationoftemperaturesettingsisavailable.We
offer a broad range of options without requiring particularly complex
technical installation criteria for all that. Its specifications, along with
its reduced dimensions and low acoustic level, offer the advantage
that the boiler can be installed more or less where you like.
Forthegeneralinstructionsoninstallation,consult chapter"Statutory
terms and conditions of installation and maintenance".
2 Application possibilities from the point of view of air and gas circulation
The standard construction of the C 210 is designed in such a way as
to make it possible, when installing the unit, to opt for an "open"
configuration(separatepipeswithorwithoutthe connection oftheair
inlet) or for a "forced flue" configuration (concentric pipes).
Direct connection to pipes built into masonry is not permitted due to
possible condensation problems. For the instructions and the flue
gas discharge tables, consult chapter "Combusted gas discharge
and air supply".
3 Hydraulic application possibilities
Given the fact that the C 210 has no constraints in terms of the
conditions of irrigation (minimum flow, return temperature, ...), it can
be connected to any kind of hydraulic system.
For more detailed information, see chapter "Technical data for
hydraulic installation".
4 Gas type
The boiler is preset in the factory to operate on natural gas H - 20
mbar. For operation on natural gas L - 20/25 mbar, it is necessary to
reset the CO2.
For more detailed information see chapter "Commissionning". The
nominal output and the CO2value must be reset.

advantage of the heating pump anti-sticking function. It is
preferable to use the "summer" modefor the period during which
the heating is to be cut off.
Furthermore,ifaninteractiveremotecontrol(CDI2)isconnected
and the 1switch is in the off 7position, there will be no display

The DIEMATIC 3 control unit is factory set to include 4 heating
programmes P1, P2, P3 and P4.
The unit is factory set to programme P1.
Programmes P2, P3 and P4 can be customised.
The choice of four programmes is particularly useful for adapting the
heating to the lifestyle of the occupants.
To select a programme from P1, P2, P3 or P4 for circuits A, B or C:
- Select the circuit using key A.B.C: The name of the circuit will be
displayed.
- Select programme P1, P2, P3 or P4 using key PROG.
The selection is validated automatically.
- The selected programme will run automatically if no override is
selected using keys %, $, .or after pressing key AUTO.
To customise programs P2, P3 and/or P4 (See page 21).
Description of the programmes
Using keys A.B.C, 2% or 2$, the heating program for the
current day can be displayed in the graph bar for each circuit
connected.
