Description
4.1
Operating principle
4. Description
4.1.1.
Gas/air setting
Air is sucked in by the fan and the gas injected into the venturi
attached to the fan inlet. The fan rotation speed modulates and adapts
to thermal energy requirements thanks to the temperatures measured
by the various sensors. The gas and air are mixed in the venturi, which
enables operation at a constant ratio. The noise of the venturi is
absorbed by a silencer attached to its inlet. The gas/air mixture is
carried to the burner in the top of the exchanger, guided by the premix channel.
4.1.2.
Combustion
The burner heats the heating water circulating in the heat
exchanger. At a return temperature lower than around 55°C, the flue
gases cool down to a temperature lower than the dew point, thus
causing the condensation of the water vapour contained in the flue
gases in the lower section of the heat exchanger. The heat released
during this condensation process (the latent heat or condensing heat)
is also transferred to the heating water. The cooled combustion gases
are evacuated via the combustion gas outlet flue. The condensation
water is evacuated via a condensate trap.

CAUTION
Do not switch off the mains supply to the appliance. If the
central heating system is not used for a long period, we
recommend activating the HOLIDAYS mode (to ensure
the anti-grip of the heating pump).

Antifreeze protection
When the heating water temperature in the boiler is too low, the
integrated boiler protection system starts up. This protection functions
as follows:
4 If the water temperature is lower than 7°C, the heating pump starts
up.
4 If the water temperature is lower than 4°C, the boiler starts up.
4 If the water temperature is higher than 10°C, the boiler shuts down
and the circulation pump continues to run for a short time.
4 If the water temperature in the storage tank is less than 4°C, it is
reheated to its set point.

The antifreeze protection does not function if the
appliance is switched off.
The integrated protection system only protects the
boiler, not the installation. To protect the installation,
set the appliance to HOLIDAYS mode.
The HOLIDAYS mode protects:
4 The installation if the outside temperature is lower than 3°C
(factory setting).
4 The room temperature if a remote control is connected and the
room temperature is lower than 6 °C (factory setting).
4 The domestic hot water tank if the tank temperature is lower
than 4 °C (the water is reheated to 10 °C).

General instructions
The boiler does not require a lot of maintenance. Nevertheless, we
recommend having the boiler inspected and serviced at regular
intervals.
4 Maintenance and cleaning of the boiler must be carried out at least
once a year by a qualified technician.
4 Have the flues swept at least once a year or more, depending on
the regulations in force in your country.
CAUTION
4
Maintenance operations must be done by a qualified
engineer.
We recommend taking out a maintenance contract.
4
Only original spare parts must be used.
4
Make certain that the flues and chimneys are
connected, in good condition and not blocked.
Do not modify nor block the condensate outlet(s).

Anti-hunting
When the boiler is in Anti-short-cycle operating mode, the symbol ?
flashes.
1. Press the "?" key.
The message Operation assured when the restart temperature
will be reachede de redémarrage sera atteinte} is displayed.
This message is not an error message but an item of
information.
7.2
Messages (Code type Bxx or Mxx)
In the case of failure, the control panel displays a message and a
corresponding code.
1. Make a note of the code displayed.
The code is important for the correct and rapid diagnosis of the
type of failure and for any technical assistance that may be
needed.
2. Switch the boiler off and switch back on.
The boiler starts up again automatically when the reason for the
blocking has been removed.
3. If the code is displayed again, correct the problem by following the

Energy savings
8.1
Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated.
4 Do not block ventilation outlets.
4 Do not cover the radiators. Do not hang curtains in front of the
radiators.
4 Install reflective panels behind the radiators to prevent heat
losses.
4 Insulate the pipes in rooms that are not heated (cellars and lofts).
4 Close the radiators in rooms not in use.
4 Do not run hot (or cold) water pointlessly.
4 Install a water-saving shower head to save up to 40 % energy.
4 Take showers rather than baths. A bath consumes twice as much
water and energy.
8.2
Recommendations
The remote control is available in the following versions:
4 Wire
4 Radio
The setting of the control panel and/or of the remote control has a
considerable influence on energy consumption.
A few tips:
4 In the room in which the room thermostat is installed, it’s advised
not to use thermostatic valve radiators. If a thermostatic valve is
used the valve must be fully opened.
4 Completely closing and opening thermostatic valve radiators
causes undesirable temperature fluctuations. Open and close
thermostatic valves in small steps.
4 Lower the temperature to around 20°C. This reduces heating costs
and energy consumption.
4 Lower the temperature when you air the rooms.
4 When setting a time schedule , bear days when you are absent
and holidays in mind.
