4.6.9 Additional Directives
Please refer to the manufacturer's instructions for the
material in question when installing the flue gas discharge
and air supply materials.
If the flue gas discharge and air supply materials are not
installed according to the instructions (e.g. they are not
leakproof, not clamped in place etc.), this may cause
hazardous situations and/or result in bodily injury.
After assembly, check at least all flue gas and air–carrying
parts for tightness.

4.7 Electrical connections

4.7.1

General

As the electrical wiring has been carefuly checked in the
factory, the internal connections on the control panel must
not be changed in any way.
Only qualified professionnals may carry out electrical
connections, always with the power off.
Electrical connections must match the electrical diagrams delivered
with the equipment and comply with the instructions in the manual.
Installation and electrical connections are to be made in accordance
with existing regulations. The appliance must be powered by a circuit
containing an omnipolar switch with an opening distance 3 mm. The
earth connection shall comply with standard NFC 15100.
All connections are made with the terminal boxes designed for
that purpose on the back of the boiler's command board.

Electrical specifications

Power supply voltage
The C 230 ECO is designed to work on 230V-50Hz with a live/neutral/
earth system. Other voltages are only authorised if using a
separation transformer.
The earthwire must be longer than 8 mm that L and N wire.
Safety box
Mains voltage: 230 V / 50 Hz
Safety time: 3.5 seconds
Pre-sweep time: 20 seconds
Post-sweep time: 20 seconds
Anti-short cycle time: 1 to 10 minutes
Power consumption
Power consumption at stop/minimum output/full output:
C 230-85: 7 W / 34 W / 125 W
C 230-130: 7 W / 36 W / 193 W
C 230-170: 7 W / 56 W / 206 W
C 230-210: 7 W / 59 W / 317 W

The connection cables should be fed into the panels through the
opening provided.
These cables will be fixed on to the control panel with cable clips
(supplied in a separate bag).
Low voltage controls :
The maximum current which may be switched per output is 2A
with cos = 0.7 (= 450W establishing current below 16A). If
the load exceeds either of these values, the control must be
relayed using a contactor that must not be installed in the
control panel under any circumstances.
The sensor cables have to be separated from the 230V circuit
cables.
Outside the boiler : Use 2 pipes or cable guides at least 10 cm
apart
Circuit breaker values
The boiler is fitted with a 4 A circuit breaker.
Temperature control
The C 230 ECO is fitted with outlet temperature, return temperature,
heating body temperature and combusted gas temperature sensors.
These sensors are used to vary boiler output according to the
temperatures measured.
The C 230 ECO is fitted with a water flow control device in which the
operating principal consists in measuring the water temperature. If
T = 30K is reached (factory setting), the boiler reduces its output by
modulating to remain in operation as long as possible.From
=40K, the boiler switches itself off, no safety shutdown. A message
is then displayed on the DIEMATIC-m3.
Maximum temperature safety
The boiler goes into safety shutdown if the temperature is too high
(110°C or less). After the breakdown has been repaired, the boiler
can be unlocked by pressing the
C 230 ECO
key.
