 Safety instructions
Please comply with the following instructions in order to avoid any risk of injury or
inappropriate use of the appliance.
Commissioning
Do not switch the appliance ON until every lling operation has been performed
Do not attempt to install this appliance yourself. This heat pump must be installed by
qualied personnel holding a certicate of competence.
The installation must always be properly earthed and tted with a safety circuit breaker.
Do not change the power supply.
The appliances are not reproof and should not therefore be installed in an explosive
environment.
How to Use
This appliance can be used by children 8 years and above. Also persons with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, provided
they have been given supervision or instruction concerning use of the appliance in a safe
way and with the appliance. Cleaning and user maintenance shall not be made by children
without supervision.
Do not let children insert foreign bodies inside the propeller protection grate or climb onto
the roof of the outdoor unit. The ns of the air heat exchanger are extremely thin and can
cause cuts.
Nothing should obstruct the air circulation through the evaporator and out from the fan.
The outdoor unit must only be installed outside. If a shelter is required,it must have broad
openings on all 4 sides and installation clearances must be observed (see your installation
engineer).
Do not climb on top of the outdoor unit.
The room in which the unit is operating must be correctly ventilated in order to avoid any
shortage of oxygen in the event of a refrigerant gas leak.
If your installation location already meets safety standards, do not carry out any
modications (ventilation, exhaust evacuation, openings, etc.) without the advice of your
installation engineer.
Do not place any heat source under the remote control.
Maintenance
Do not try to repair the appliance yourself.
This appliance does not contain any components which can be repaired by the user.
Removing either of the covers can expose you to dangerous electrical voltages.
In any case, switching o󰀨 the current is not su󰀩cient to protect you from any external
electrical shocks (condensers).
Do not open the outdoor unit or the hydraulic unit while they are in operation.
If you hear unusual noises, smell smoke or other odours coming from the appliance, turn
o󰀨 the power and contact your installation engineer.
Before starting any cleaning, turn o󰀨 the power to the appliance.
Do not use aggressive cleaning liquids or solvents to clean the body work.
Do not use a pressure hose to clean the outdoor unit. You may damage the air exchanger
and get water inside the electrical circuits.

Precautions and warnings about
your installation
▼
Outdoor unit
The outdoor unit contains the equipment that enables
the capture of energy from the surrounding air.
This unit was installed by your installer in a location
where it is able to operate with best performance.
Nothing should obstruct the air circulation through the
evaporator and out from the fan.
The water contained in the air may condense and ow
out of the outdoor unit. The outdoor unit can generate a
large volume of water called condensate.
In cold weather, this water freezes on contact with the
exchanger and must be regularly removed using the
defrosting cycles. The defrosting cycle is managed
automatically by the control system and can produce
steam emissions which are completely normal.
▼
Hydraulic unit
The hydraulic unit contains the appliance's control
system which manages the room temperature and the
production of domestic hot water.
The hydraulic unit is tted with an electrical backup*
or boiler connection* which intervenes to provide
additional heat during the coldest periods.
▼
Settings
Your installer has carefully adjusted your installation.
Do not change the settings without their consent.
If in doubt, do not hesitate to contact them.
Your heating system is controlled by adjustment in
relation to the outside temperature (temperature
control).
The installation of a room thermostat (option) makes it
possible to improve the operation of the control system
(inuence of the ambient temperature is taken into
account).
▼
Radiators
In order to ensure operation of the control system,
the room containing the thermostat must not also
contain a thermostatic valve. If this is the case, it must
be opened as far as possible.
▼
Underoor heating system
A new underoor heating system must initially be
heated slowly to avoid any problems involving cracking.
Check with your installer that this initial heating
procedure has indeed been performed before freely
using your heating system.
An underoor heating system's signicant inertia
prevents sudden room temperature di󰀨erences.
However, this inertia implies a reaction time of around
several hours (approx 6 hours).
Any changes to the setting must be made slowly
and leave the installation su󰀩cient time to react. Any
exaggerated or abrupt adjustments to the settings
always result in signicant temperature uctuations
during the day.
Similarly if your dwelling has an underoor heating
system, do not reduce it or switch it o󰀨 if you will be
absent for only short periods. The reheating period is
always quite long (approx 6 hours).
▼
Fan coils / dynamic radiators with an
integrated control system
Do not use a room sensor in the area in question.
▼
Domestic Hot Water (DHW)*
When hot water is required, the heat pump adapts its
priority to meet the request.
No heating is produced during the preparation of
domestic hot water.
The heat pump produces the domestic hot water
(DHW), which is then additionally heated, if required,
by the electrical backup.
To ensure a DHW setpoint over 45°C, the electrical
backup heating or boiler (boiler connection kit)* must
be left on.
The electrical backup allows the correct operation of the
anti-legionella cycles.

Appliance end-of-life
The appliances must be dismantled and recycled by a
specialised service. The appliances must not, under any
circumstances, be thrown out with household waste,
bulky waste or at a tip.
At the end of its service life, please contact your installer
or local representative to proceed with its dismantling
and recycling.

Overview of the installation
Your heat pump has been congured by your installation
engineer. It is made up of the following main parts:
- The outdoor unit, as its name suggests, is placed
outside your dwelling, and extracts energy from the
outside air.
- The hydraulic unit is located in your boiler room, cellar,
garage or even in your kitchen, and transfers energy to
the heating and domestic hot water circuits*.
- The outside sensor monitors the outside temperature.
Optional:
- Room sensor(s).
Heat pumps are systems which can be connected to
any type of low temperature distribution system and
the heat captured by the heat pump can be used in
di󰀨erent ways:
- Underoor heating system.
- Radiators.
- Domestic Hot Water (DHW)*.

Details
If the electrical power supply has been cut o󰀨 while
the heat pump is operating (electrical power failure or
unprogrammed pressing of the on/o󰀨 switch on the
hydraulic unit) the display will show error 370 when
the appliance restarts. Do not be concerned, the
communication between the outdoor and hydraulic unit
will re-establish itself in a few moments.
►
Operation of the DHW system*
The key enables you to switch the DHW (domestic hot
water) mode on and o󰀨. 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 back-
up 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).
►
Selecting cooling mode*
If the installation is tted with the cooling kit.
The key activates and deactivates cooling mode.
►
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 di󰀨erence 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.

Telephone modem* (if Regulation
extension kit AVS 55)
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.

 Maintenance
In order to ensure that your appliance operates correctly
for many years, the maintenance operations described
below are required at the start of each heating season.
They are generally carried out as part of a maintenance
contract.
►
Regular checks
- Check the water pressure in the heating circuit
regularly (refer to the installer's recommended
pressure - between 1 and 2 bar)
- If a lling operation and a pressure increase are
required, check what type of uid was used initially
(when in doubt, contact your installer).
- If frequent rells are required it is absolutely essential
that you check for any leaks.
The frequent addition of water risks scaling the
exchanger and a󰀨ects its performance and lifespan.
►
Checking the outdoor unit
Remove any dust from the exchanger, if necessary,
while making sure not to damage the blades.
Check that there is nothing blocking the air ow.
• Checking the refrigeration circuit
If the amount of refrigerant in the system exceeds 2kg
(models > 10 kW), the refrigeration circuit must be
checked annually by an approved engineer (they must
have a certicate of competence for the handling of
refrigerants).
Consult your heating technician.
►
Hot water tank*
Maintenance on the tank must be carried out annually
(frequency may vary according to water hardness).
Consult your heating technician.
