Installation shutdown
If the central heating system is not used for a long period, we recommend switching the boiler off.
4
Switch the On/Off switch to Off.
4
Switch off the boiler electrical power supply.
4
Close the oil inlet.
4
Ensure that the boiler and system are protected against frost damage.
4
The boiler and the chimney must be swept carefully.
4
Close the door of the boiler to prevent the internal circulation of air.

Antifreeze protection
15/07/2015 - 300026440-05
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.

5. Operating the appliance AFC 18 - AFC 24 - AFC 30
CAUTION
4
The antifreeze protection does not function if the appliance is switched off.
4
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).

8.1
Energy-saving advice
AFC 18 - AFC 24 - AFC 30
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.

You have just purchased one of our appliances and we thank you for the trust you have placed in our products.
Please note that your appliance will provide good service for a longer period of time if it is regularly checked and maintained.
Your installer and our customer support network are at your disposal at all times.
The following provisions are not exclusive of the buyer being able benefit from the legal provisions applicable regarding hidden defects in the buyer’s country.
Starting from the purchase date shown on the original installer’s invoice, your appliance has a contractual guarantee against any manufacturing defect.
The length of the guarantee is mentioned in the price catalogue.
The manufacturer is not liable for any improper use of the appliance or failure to maintain or install the unit correctly (the user shall take care to ensure that the system is installed by a qualified engineer).
In particular, the manufacturer shall not be held responsible for any damage, loss or injury caused by installations which do not comply with the following:
4 applicable local laws and regulations,
4 specific requirements relating to the installation, such as national and/or local regulations,
4 the manufacturer’s instructions, in particular those relating to the regular maintenance of the unit,
4 the rules of the profession.
The warranty is limited to the exchange or repair of such parts as have been recognised to be faulty by our technical department and does not cover labour, travel and carriage costs.
The warranty shall not apply to the replacement or repair of parts damaged by normal wear and tear, negligence, repairs by unqualified parties, faulty or insufficient monitoring and maintenance, faulty power supply or the use of unsuitable fuel.
Sub-assemblies such as motors, pumps, electric valves etc. are guaranteed only if they have never been dismantled.
The legislation laid down by european directive 99/44/EEC, transposed by legislative decree No. 24 of 2 February 2002 published in O.J. No. 57 of 8 March 2002, continues to apply.
