1 Safety instructions

Please comply with the following instructions in order to avoid any risk of injury or inappropriate use of the appliance.

• Start-up

" Do not switch the appliance on until every llings have been done. " Do not try to install this appliance yourself. " This heat pump requires an appropriately qualied person to install it. " The installation must always be connected to the Earth and tted with a protective circuit breaker. " Do not modify the electricity supply. " The appliances are not reproof and should therefore not be installed in a potentially explosive

atmosphere.

• Use

" Do not let children insert foreign bodies into the fan protection grill or climb on top of the outdoor

unit. The ns on the air exchanger are extremely ne and cause cuts.

" Nothing should obstruct the air circulation through the evaporator and from the fan. " The outdoor unit must only be installed outdoor (outdoors). If a shelter is required, it must have

broad openings on the 4 walls and observe the installation clearances (see with your installer).

" Do not climb on the top of the outdoor unit. " The room in which the appliance is operating must be correctly ventilated in order to prevent any

loss of oxygen if there is an escape of refrigerant gas. " Consult your Installer before making any changes or modications to the premises where the

appliance is installed. " Do not place any heat source under the room control unit.

• Maintenance

" Do not try to repair this appliance yourself. " This appliance does not contain any components capable of being repaired by the user himself.

Removing one or other of the covers can expose you to dangerous electrical voltages. " In any case, switching off the current is not sufcient to protect you from any external electrical

shocks (capacitors). " Do not open the outdoor unit or the hydraulic unit while they are operating. " Switch off the power supply if there are any abnormal noises, smells or smoke coming from the

appliance and contact your installer. " Switch off the power to the appliance before you clean it. " Do not use aggressive cleaning liquid or solvents to clean the body work. " Do not use a pressure washer to clean the outdoor unit. This could damage the air exchanger

and the water might penetrate into the electrical circuits.

2 Overall view of the installation

2 1 Precautions and warnings regarding your installation

2 1 1 The outdoor unit

The outdoor unit contains the equipment for capturing

energy from the ambient air.

Your installer has placed this unit in a location that

enables it to operate in an optimum manner. Nothing should obstruct the air circulation through the

evaporator and from the fan.

The water that the air contains condenses and ows

from the external unit. In cold periods, this water freezes in contact with the

exchanger and is drained away by regular defrosting

cycles. The control system automatically controls the defrosting cycle, whose operation can lead to the quite normal emission of steam.

2 1 2 The hydraulic unit

The hydraulic unit contains the heat pump complete control system, in charge of controlling the heating comfort level (and the production of domestic hot water -

if the installation is tted with a DHW tank with electrical back-up heating). The heat pump is equipped with an electrical back-up

system, which is designed to provide additional heat during the coldest periods.

2 1 4 The radiators

To ensure the function of the regulation with room

inuence, it's necessary that the room in which the room

thermostat is installed has no thermostatic valve or that

they must be completely open.

2 1 5 Floor-heating systems

New oor-heating systems require to be initially heated slowly to avoid any problems with cracking. Check

with your installer that this initial heating procedure

has indeed been performed before using your heating

system freely.

The great stability in a regulation system for oor-heating

systems avoids sharp differences in temperature.

However, this stability involves a reaction time of the

order of several hours, (approx 6 hours).

Any changes to the setting must be made slowly, leaving

the installation time to react. Adjusting the system to exaggerated setting or in an untimely manner always

results in signicant temperature uctuations during

course of the day.

Similarly if your dwelling has a oor-heating system, do not reduce the heating or switch it off if you will be absent for a short period. The reheating period is always

quite long (approx 6 hours).

2 1 3 Control system

Y our installer has carefully adjusted your installation. Do not modify setting parameters without his agreement. If

in doubt, do not hesitate to contact him.

The control system for your heating system is designed

in ow temperature for the water based on the outdoor

temperature (water control). The installation of a room thermostat (option) allows to

improve operation of the regulation (the inuence of the

room temperature is taken into account).

2 1 6 Fan convectors / Dynamic radiators with integrated control system

Do not use a room sensor in the area.

2 1 7 Domestic hot water (DHW)

When the DHW production is required, the heat pump adapts to this demand with higher priority.

No space heating is produced while the domestic hot

water is being prepared. Domestic hot water (DHW) is produced by the heat

pump and then topped up, if necessary, by electrical backup heating or the boiler.

To ensure a DHW setting over 45°C, the electrical backup heating or the boiler must be left on (Optional boiler

connection kit).

The electrical back-up heating enables anti-legionella cycles to be conducted efciently.

2 2 End of life of the device

Disassembly and recycling shall be handled by a qualied body. Wild disposal is strickly prohibited.

At the end-of-life of the equipment, please contact your installor or any local representant to proceed to

disassembly and recycling.

2 3 Overall view of the installation

Your heat pump has been congured by your installer. It

is composed of the following main elements:

-The outdoor unit is positioned, as its name indicates, outdoor your dwelling and extracts energy from the outdoor air.

-The hydraulic unit positioned in your boiler room, cellar, garage or even your kitchen, transfers the energy to the heating circuit (and the domestic hot water).

-The outdoor sensor detects the outdoor temperature.

Optional equipment:

-Room thermostat.

-Room control unit.

Heat pumps are systems that can be connected to any

form of low temperature heat distribution systems :

the heat captured by the heat pump can therefore be

used in different ways:

-Floor-heating systems.

-Radiators or fan coil heaters.

-Domestic hot water (DHW).

3 10 Operation of the DHW system

The key enables you to switch the DHW (domestic hot water) mode on and off. The selection is shown by a bar, which appears under the corresponding symbol.

Manual activation: Hold down the DHW key for 3 seconds (Switch from "reduced" to "nominal" until the next time the DHW timer switches over).

To ensure a DHW setting over 45°C, the electrical backup heating or the boiler must be left on.

In order to optimise operation of the DHW, it is possible to:

-Program the timer settings (parameters 560 to 576),

-Adjust the comfort temperature set point (parameter 1610),

-Adjust the reduced temperature set point (parameter 1612).

Press the info key to obtain the details on the DHW

(temperature setting operation).

3 12 Pilot wire

(if kit regulation extension AVS 55)

It's possible to order up to 15 electric heaters via output

"pilot wire". The "pilot wire" handles only the hourly operation

of electric heaters (comfort mode / reduced mode commutation and Frost protection mode).

The comfort temperature setting should be done

directly on the electric heater(s). The "pilot wire" does not handle the temperature of the electric heaters. Refer to the manual supplied with the electric heater(s).

Put the electric heaters on "PROG" mode or "AUTO"

mode for piloting by the regulation board. The difference between the comfort temperature and

the reduced temperature is from 3,5 ° C. Frost protection temperature is set directly on the

electric heaters. Refer to the manual supplied with the electric heater(s).

In the absence of signal, electric heaters operating in

comfort mode.

3 13 Telephone modem (if Regulation extension kit AVS 55)

gure 12 - Selecting cooling mode

gure 13 - Selecting the frost protection

It is possible to command the switching of the heating

mode to the "freeze" protection mode / reduced (and vise versa) on the heat pump using a modem contact.

The telephone command switches the current heat pump settings to "freeze" protection mode / reduced (and vise versa). In accordance with the setting, any temperature requests from the heating circuits and the DHW are ignored or activated.

The "freeze" protection mode / reduced must not be

selected on the heat pump and/or the remote control. See with your installer.

4 Maintenance

In order to insure your appliance operates correctly for

many years, the maintenance operations described below are required at the start of each heating season.

Generally, these are performed as part of a service contract.

4 1 Regular checks

-Periodically check the water pressure in the heating

circuit (Refer to the pressure recommended by the installer - between 1 to 2 bar).

-If lling and re-pressurization are required, check what

type of uid has been used initially (If in any doubt,

contact your installer).

-If frequent rells are required it is essential that you look for any leaks.

-The frequent water supply is at risk of scaling for

the Heat exchanger and degrades performance and longevity of it

4 2 Checking the outdoor unit

Dust off the heat exchanger if necessary, being careful not to damage the ns.

Check that there is nothing obstructing the passage of air.

• Checking the refrigeration circuit

When the refrigerant charge is in excess of 2kg (models > 8 kW) it is compulsory to have an approved after sales service check the refrigeration circuit every

year (with a certicate of capacity for the handling of

refrigerants). Consult your heating technician.

LED Off: The pump does not work, no electrical power.

Green LED on: The pump works normally.

Green LED blink: Venting operating mode (10 minutes).

Green/Red LED blink: Operating error with automatic reboot.

Red LED blink: Operating error.
