Heat pump Alfea S

1 Description of the unit

1.1 Package

• 1 package : Outside unit.

• 1 package : hydraulic module and outdoor sensor.

1.2 Denitions

Split: The heat pump consists of two elements (an
outside unit for outside and a hydraulic module for
inside the dwelling).

Air/water: The surrounding air is the energy source. This
energy is transmitted to the water in the heating circuit
by the heat pump.

Inverter: the fan and compressor speeds are modulated
according to the heating requirements.

This technology enables you to save on energy and
operate on a single-phase power supply, whatever the
heat pump’s output, by avoiding heavy intensities on
start-up.

COP (coefcient of performance): this is the relationship
between the energy transmitted to the heating circuit
and electrical energy consumed.

Scope of application

This heat pump provides :
Heating in winter,

- Control of two heating circuits*,

- Production of domestic hot water*
(provided that combined with a DHW tank).

- Cooling* in summer (for oor heating-cooling system
or fan-convectors).

- Installation with boiler connection* as a supplementary
heating for the coldest days.

- Heating the swimming pool*.

* :

These options require the use of additional kits

(see § "Optional equipment").

Heat pump Alfea S

1.6 Operating principle

The heat pump transmits the energy contained in the
surrounding air into the dwelling to be heated.

The heat pump consists of four main elements, in which
a refrigerant uid (R410A) circulates.

- In the evaporator (rep. 13, gure 7, page 11) :
The energy is taken from the surrounding air and is
transmitted to the refrigerant. Because it has a low
boiling point, it changes from the liquid state to the
vapour state, even in cold weather (down to -15 °C
outside temperature).

- In the compressor (rep. 10, gure 7 , page 11) :
The vaporised refrigerant brought to high pressure
and takes on more calories.

- In the condenser (rep. 15, gure 8, page 12) :
The energy in the refrigerant is transmitted to the
heating circuit. The refrigerant returns to liquid state.

- In the expansion valve (rep. 9, gure 7, page 11) :
The liqueed refrigerant is brought back to low pressure
and returns to its initial temperature and pressure.

The heat pump is equipped with a controller, which
controls the internal temperature based on the outside
temperature measurement and governed by the
temperature control.

The room thermostat (optional) provides a corrective
action for the temperature control.

The hydraulic module is equipped with an electric back­ups system, which is triggered to provide additional heat
during the coldest periods.

Domestic hot water (DHW) operating principle

Two domestic hot water (DHW) temperatures can be
parametered: comfort temperature (line 1610 to 50 °C)
and reduced temperature (line 1612 to 25 °C).

Setting for reduced temperature can be useful to prevent
the DHW from switching on too often and for too long
during the day.

The production of domestic hot water (DHW) is triggered
when the temperature in the tank falls 7°C (setting from
line 5024) below the set temperature.

The heat pump produces the domestic hot water, which
is then supplemented, if required, by electrical backup
heating from the tank.

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

Depending on how the parameter (1620) is set, comfort
temperature can be reached 24h/day or only at night or
depending on the heat pump programme.

If the contract concluded with the energy provider
includes a subscription to day/night tariff, the electrical
backup is subordinate to the supplier’s power tariff and
the comfort temperature may only be reached at night.

If no particular contract is concluded, the comfort
temperature can be reached at any time, including
during the day.

The production of DHW takes priority over heating;
nevertheless the production of DHW is controlled by
cycles that control the times assigned to the heating
and the production of DHW in the event of simultaneous
demand.

A function to switch from "reduced" to "comfort" is
provided on the front of the user interface (see ref. 1,

gure 39, page 31 ).

This DHW boost enables the DHW to be heated to the
comfort temperature at any time during the day. The
boost function is cancelled automatically when the
demand for hot water has been met.

If the heating installation is equipped with a DHW
circulation pump, the pump’s operation during DHW
cycles can be parametered.

Anti-legionella cycles can be programmed.

• Fan convectors with integrated control system

Do not use a room sensor in the area.

Accessories provided with the outside unit (gure 10).
Accessories provided with the hydraulic module

(gure 11).

2.3 Installation position

The choice of the position for installation is particularly
important insofar as any later movement is a delicate
operation requiring the intervention of a qualied
person.

Choose the site of the outside unit and the hydraulic
module after discussion with the customer.

Observe the maximum and minimum distances between
the hydraulic module and the outside unit (gure 13);
the guarantee of the performances and the system’s
service life depend on this.

2.4 Installation of the outside unit

2.4.1 Installation precautions

" The outside unit must only be installed outside

(outdoors). If a shelter is required, it must have
broad openings on the 4 walls and observe the
installation clearances (gure 12).

• Choose a site that is preferably sunny and sheltered
from strong cold predominant winds (mistral,
tramontana, etc…).

• The unit must be easily accessible for future installation
and maintenance work (gure 12).

• Ensure that it is possible to make the connections to
the hydraulic module easily.

• The outside unit is able to withstand bad weather but
avoid installing in a position where it is likely to be
exposed to signicant dirt or owing water (under a
defective gutter for example).

• Water may drain away from the outside unit when it
is operating. Do not install the appliance on a paved
terrace; choose a well-drained place (e.g. gravel
or sand). If the installation is in an area where the
temperature can be lower than 0°C for a long period,
check that the presence of ice does not present any
danger. A drainage pipe can also be connected to
outside unit (see para 2.4.3, page 16).

• Nothing should obstruct the air circulation through the
evaporator and from the fan (gure 12).

• Keep the outside unit away from heat sources and
inammable products.

• Make sure the appliance not disturb the surrounding
area or users (noise level, draught generated, low
temperature of the air being blown out, with the risk of
freezing plants in its path).

• The surface supporting the outside unit should :

- be permeable (soil, gravel, etc),

- support its weight easily,

- provide a solid xing and

- not transmit any vibration to the dwelling.

Anti-vibratory blocks are available, please consult your
retailer.

• The wall brackets is strongly discouraged due to
vibration.

2.4.2 Outside unit positioning

The outside unit must be raised at least 50 mm above
ground level. In areas prone to snow, this height should
be increased but should not exceed 1,5 m (gure 14).

- Fasten the outside unit by means of screws and
rubber tightening or toothed lock washers to avoid
their coming loose.

2.4.3 Condensate drain hose

(see gure 14).
If the use of a discharge pipe is imperative :

- Use the elbow provided (C) to connect a 16mm
diameter hose for draining away the condensate.

- Use the stopper or stoppers provided (B) to block the
opening of the condensate tank.

Allow for the condensate to ow away under the force of
gravity (waste water, rain water, gravel bed).

" If the installation is made in an area where

the temperature can be lower than 0°C for
a long period, provide the drain pipe with a
trace resistance to avoid it icing up. The trace
resistance must heat not only the pipe but
also the bottom of the appliance’s condensate
collection tank.

2.5 Installing the hydraulic module

2.5.1 Installation precautions

• The room in which the appliance operates must comply
with the prevailing regulations.

• To facilitate maintenance and to allow access to the
various components, we recommend that you provide
sufcient space all around the hydraulic module
(gure 15).

• Be careful not to bring inammable gas near to the
heat pump during its installation, in particular when it
requires brazing.

The appliances are not reproof and should not therefore
be installed in a potentially explosive atmosphere.

2.5.2 Positioning the hydraulic module

- 1, 2, 3 : Remove the front panel
(2 screws A, gure 16).

- 4, 5 : Remove the sides

(4 screws B, gure 17).

- Fix the support solidly (3 screws and plugs) to a at,
hard-wearing wall (not a light partition) ensuring that it
is correctly levelled.

- Hook the appliance onto its support.

- Ret the sides.

- Ret the front facing.

2.6 Refrigeration connections

" This appliance uses refrigerant R410A.

Comply with the legislation for handling refrigeration
uids.

2.6.1 Rules and precautions

• After every intervention on the refrigeration circuit and
before nal connection, take care to replace the plugs
in order to avoid any pollution from the refrigeration
circuit.

• Tools

- Set of manometers with hoses exclusively reserved
for HFCs (Hydrouorocarbons).

- Vacuum pump specially for HFCs.

- Provision on using tools that have been in contact with
HCFCs (R22 for example) or CFCs.

- Use of a traditional vacuum pump is authorized if, and
only if, it is tted with a non-return valve on the suction
side.

The manufacturer declines any liability with regard to the
guarantee if the above instructions are not observed.

• Flared connections

" Lubrication with mineral oil (for R12, R22) is

forbidden.

- Only lubricate with polyolester refrigeration oil (POE).
If POE is not available, t without lubrication.

• Brazing on the refrigeration circuit (if necessary)

- Silver brazing (40% minimum recommended).

- Brazing only under dry nitrogen internal ux.

• To eliminate any lings in the pipes, use dry nitrogen
to avoid introducing any humidity that may adversely
affect the appliances operation. In general, take every
precaution to avoid humidity penetrating into the
appliance.

• Use pipe insulators resistant to temperatures over
120°C. In addition if the humidity level in areas where
the refrigeration pipes are installed is expected to
exceed 70%, protect the pipes with pipe insulators.
Use an insulating material thicker than 15mm if the
humidity level is 70~80%, and an insulating material
thicker than 20mm if the humidity exceeds 80%. If the
recommended thicknesses are not observed under the
conditions described above, condensation will form on
the surface of the insulation material. Lastly, take care
to use pipe insulators whose thermal conductivity is

0.045 W/mK or less when the temperature is 20°C. The
insulation must be impermeable to resist the passage
of steam during the defrosting cycles (breglass wool
is prohibited).

2.6.2 Refrigeration connections

The outside unit must be connected to the hydraulic
module with copper pipes and connections (refrigeration
quality), insulated separately.

Comply with the pipe diameters and the permitted pipe
lengths (gure 13).

The minimum length of the refrigeration connections
is 5m for correct operation (except model S5 and S6,

see gure 13).
The appliance will be excluded from guarantee if it is

used with refrigeration connections less than 5m long
(models S8, S10, S13, S16).

Manipulate the pipes and take them through walls with
protective plugs in place.

If the distance between the outside unit and the hydraulic
module exceeds the length of the maximum conduits
indicated in the table, an additional charge of R410A
must be loaded.

The quantity of R410A added must be adapted to the
length of the refrigeration circuit in order to the heat
pump’s performance without damaging the compressor
(gure 23).

2.6.3 Creating the arings

- Cut the pipe to an appropriate length with a pipe-cutter
without deforming it.

- Carefully deburr it, holding the pipe towards the bottom
to avoid introducing lings into the pipe.

- Remove the ared connection nut situated on the valve
to be connected and slip the pipe into the nut.

- Proceed to are, letting the pipe overow the aring
tool.

- After aring, check the condition of the working radius
(L). This must not show any scratch or trace of any
fracturing. Also check the dimension (B).

2.6.4 Shaping the refrigeration pipes

The refrigeration pipes must be shaped only on a
bending machine or with a bending spring in order to
avoid any risk of crushing or breaking them.

" Warning

• Remove the insulation material locally to bend the
pipes.

• Do not bend the copper to any angle over 90°.

• Never bend pipes more than 3 times in the same
position otherwise traces of fracturing may appear
(from strain-hardening the metal).

2.6.5 Connecting the ared connections

" The small pipe must always be connected before

the large one.

" Take particular care positioning the tube opposite

its connector so as not to risk damaging the
threads. A carefully aligned connector can be
tted easily by hand without much force being
required.

" The refrigeration circuit is very sensitive to dust

and humidity: check that the area around the
connection is clean and dry before removing the
plugs protecting the refrigeration connectors.

2.7 Filling the installation with gas

" This operation is reserved for installers familiar

with the legislation for handling refrigeration
uids.

" Creating a vacuum with a vacuum pump is

essential.

" Never use equipment used beforehand with any

refrigerant other than a HFC.

2.7.1 Creating a vacuum and lling
the refrigeration connections with gas

(see gure 22).

- Remove the protective plugs (B) from the charging
hole (Schrader) in the gas valve (large diameter).

- Connect the blue hose (on the side with a valve
pusher in good condition) from the set of manometers
(manifold).

- Connect the yellow hose to a vacuum pump and open
the blue valve on the set of manometers.

- Create a vacuum until the residual pressure in the
circuit falls below 0.01 bar.

- Let the pump continue to operate for another 15
minutes after reaching the vacuum.

- Close the blue valve on the set of manometers and
then stop the vacuum pump without disconnecting
any of the hoses in place.

- Wait 10 minutes. If the pressure rises during this
10-minute period, there is a leak in the circuit. Trace it
and repair it: then start again.

When the pressure has remained stable for 10
minutes after the vacuum pump stops, the circuit
is considered to be gas-tight.

- Remove the access plugs (A) from the valve controls.

" If an additional charge is requires, add the

additional charge before lling the hydraulic
module with gas. Please refer to the section
(“Additional charge”, page 22).

- First of all fully open the small valve and then the
large one using a hex key (counterclockwise direction)
without forcing excessively against the stop.

- Remove the blue hose rapidly.

- Ret the 2 plugs and tighten them to the recommended
tightening torque (see gure 21).

The outside unit does not contain any additional
refrigerant, enabling the installation to be purged.

Flushing is strictly forbidden.

2.7.2 Sealing test

Once the refrigeration circuit has been gassed as
described above, check that all the refrigeration
connectors are gas-tight:

6 connectors for models S5 and S6, 5 connectors for
model S8 and 4 connectors for models S10, S13 and
S16.

The sealing test must be performed with an approved
gas detector.

If the arings have been made correctly, there should
be no leaks.

" If there is a leak, make the connection again.

2.7.3 Additional charge

The charge in the outside units corresponds to the
maximum distances between the outside unit and the
hydraulic module dened in gure 13. If the distances
are greater, an additional charge of R410A is required.
The additional charge depends on the distance between
the outside unit and the hydraulic module for each type
of appliance (gure 23). The additional charge of R410A
must necessarily be made by an approved refrigeration
engineer.

• Example for a heat pump model S16

An outside unit 32m away from the hydraulic module
will require an additional charge of :

Additional charge = (32 - 20) x 40 = 480 g.

The charge must be introduced after creating the
vacuum and before the hydraulic module is lled with
gas, as follows :

- Disconnect the vacuum pump (yellow hose) and
connect a bottle of R410A instead in the uid
extraction position.

- Open the bottle’s valve.

- Bleed the yellow hose by loosening it slightly on the
manifold side.

- Place the bottle on scales with a minimum accuracy of
10g. Note the weight.

- Carefully open the blue valve slightly and check the
value shown on the scales.

- As soon as the value displayed has dropped by the
value for the calculated additional charge, close the
bottle and disconnect it.

- Then rapidly disconnect the hose connected to the
appliance.

- Proceed to ll the hydraulic module with gas.

" Warning

• Only use R410A !

• Only use tools suitable for R410A
(set of manometers).

• Always charge in the uid phase.

• Never exceed the length or the maximum difference
in level.

2.8 Connecting
the heating circuit hydraulically

2.8.1 General

The connection must comply with good trade practice
according to local building regulations.

The heating circulating pump is built into the hydraulic
module.

Connect the central heating pipes to the hydraulic
module, complying with the direction of circulation.

The diameter of the pipes between the hydraulic
module and the heating collector must be at least 1 inch
(26x34mm).

Calculate the diameter of the pipes according to the ow
rates and the lengths of the hydraulic systems.

Tightening torque : 15 to 35 N.m.
Use union connectors to facilitate removing the hydraulic

module.
Preferentially use connection hoses to avoid transmitting

noise and vibrations to the building.
Connect the drains from the drain valve and the safety

valve to the main sewer system.
Reminder: Seal everything when tting in accordance

with prevailing trade practice for plumbing work :

- Use suitable seals (bre seals, o-rings).

- Use Teon tape or hemp.

- Use sealing paste (synthetic depending on the case).

The use of glycol is not necessary. If you are using a
glycol/water mix, provide for an annual check on the
quantity of glycol.

In certain installations, the presence of different metals
can cause corrosion problems; the formation of metal
particles and sludge in the hydraulic circuit is then
seen.

In this case, it is advisable to use a corrosion inhibitor in
the proportions indicated by its manufacturer.

It is also necessary to ensure that the treated water
does not become aggressive.

2.8.2 Rinsing out the installation

Before connecting the hydraulic module to the
installation, rinse out the heating system correctly to
eliminate any particles that may affect the appliance’s
correct operation.

Do not use solvents or aromatic hydrocarbons (petrol,
parafn, etc.).

In the case of an old installation, provide a sufciently
large decanting pot with a drain on the return from the
boiler and at the lowest point in the system in order to
collect and remove the impurities.

Add an alkaline product to the water and a dispersant.
Rinse the installation several times before lling it

denitively.

2.8.3 Filling and purging the installation

Check the pipe xings, the tightness of the connectors
and the stability of the hydraulic module.

Check the direction in which the water is circulating and
that all the valves open.

Proceed to ll the installation.
Do not operate the circulating pump while lling. Open

all the drain valves in the installation and the bleed valve
for the hydraulic module to remove the air contained in
the conduits.

Close the drain and bleed valves and add water until the
pressure in the hydraulic circuit reaches 1.5 bar.

Check that the hydraulic circuit has been purged
correctly.

Check that there are no leaks and that the circulating
pumps are not seized (if need be, release them).

After the “Start-up” stage (see page 30), once the
machine has started, purge the hydraulic module again
(2 liters of water).

Ensure that the general electrical power supply has
been cut off before starting any repair work.

2.9.1 Characteristic of the electrical supply

The electrical installation must be conducted in
accordance with the prevailing regulations.

The electrical connections must only be made when all
the other tting operations have been completed (xing,
assembly, etc.).

" Warning

The contract concluded with the energy provider must
be sufcient not only to cover the heat pump’s power
but also the combined sum of all the appliances likely to
be operating at the same time.

When the power is too low, check with your energy
provider the value subscribed to in your contract.

Never use a socket for the power supply.
The heat pump must be supplied with power by special

protected leads from the electric panel via 2-pole circuit
breakers specially dedicated to the heat pump :

Curve D for the outside unit, curve C for the electric
heating and domestic water back-ups (see tables on

page 25).

The electrical installation must necessarily be equipped
with a 30mA differential protection.

This appliance is intended to operate under a nominal
voltage of 230V +/- 10%, 50 Hz.

2.9.2 General remarks on electrical connections

It is essential to maintain the live-neutral polarity when
making the electrical connections.

Tighten the screws on the terminal blocks perfectly.
Unsufcient tightening can cause overheating, leading
to breakdown or even a re.

Use cable clamps to prevent the conductors from being
disconnected accidentally.

Connection to Earth and Earth bonding continuity are
essential.

• Connecting to screw terminals
Rigid wires (A, gure 28).

Rigid wires are always preferable for xed installations,
particularly in a building.

- Always select a wire that complies with the prevailing
standards.

- Strip away around 25 mm from the end of the wire.

- With round end pliers, form a loop with a diameter
corresponding to the tightening screws on the
terminal.

- Tighten the terminal screw rmly onto the loop
created.

Flexible wires (B, gure 28)
H07RNF type (or superoir quality) exible wire can be

used with certain precautions :

- Strip away around 10mm from the end of the wire.

- With tightening pliers, t a round tag with a diameter
corresponding to the terminal screw’s diameter on the
end of the wire.

- Tighten the tag rmly onto the terminal with a
screwdriver.

- We strongly advise against using exible wires without
round tags.

- Always protect the cables when passing them through
cable clamps with PVC protective conduit 0.5 to 1mm
thick.

• Connecting to regulation cards

- Remove the corresponding connector and make the
connection.

• Connecting to spring terminals (gure 30)

• External faults the heat pump

Any component of carryforward of information
(thermostat, pressure switch, etc.) may signal an
external problem and stop the heat pump.

- Connect the external component to input EX6.

• 230 V on input EX6 = stoppage of heat pump (the
system displays Error 369).

- In the case of a heated oor, Connect the oor heating
safety device into the connector of the oor heating
pump (QX3 - circuit 1, QX23 - circuits 2).

2.10 Outdoor sensor

The outdoor sensor is required for the heat pump to
operate correctly.

Consult the tting instructions on the sensor’s packaging.
Place the sensor on the coldest part, generally the

northern or north-eastern side.
In any case, it must not be exposed to the morning sun.
It must be installed so as to be easily accessible but at

least 2.5m from the oor.
It is essential that it avoid any sources of heat such as

ues, the upper parts of doors and windows, proximity

to extraction vents, the underneath of balconies and
under-eave areas which would isolate the sensor from
variations in the outside air temperature.

- Connect the outdoor sensor to the M and B9 terminals
on the heat pump control board (gure 38, page 29).

2.11 Room thermostat
and/or room control unit

The room thermostat (room control unit) is optional.
Consult the tting instructions on the sensor’s

packaging.
The sensor must be installed in the living room area on

a very uncluttered wall, 1.5m above the oor.
Avoid direct sources of heat (chimney/ue, television,

cooking hobs), draughty areas (ventilation, door, etc.).
Air leaks in the seals in the constructions are often

translated into cold air blowing through the electrical
conduits. Lag the electrical conduits if there is a cold
draught on the back of the IR sensor.

2.12 Start-up

- Close the installation’s main circuit breaker.

On rst commissioning (or in winter), in order to allow
the compressor to pre-heat, engage the installation’s
main circuit breaker (power supply to the outside unit)
some hours before starting up the tests.

- Engage the heat pump’s ON/OFF button.

To ensure that inputs EX4, EX5 and EX6 operate
correctly : Check that the live-neutral polarity of
the electrical supply is correct.

When the power is switched on and every time that the
ON/OFF button is switched off and then switched on
again, the outside unit will take approximately 4 minutes
to start up, even if the setting is requesting heating.

The display can show error 370 when the
appliance (re)starts. Do not be concerned,
the communication between the outdoor and
hydraulic units will re-establish itself in a few
moments.

- Make all the specic adjustments to the setting
(conguring the installation).

- Press the key

OK

- Hold down the key for 3s and select the level of

access used with the aid of the knob .

- Conrm with the key

OK

.

- Parameter the heat pump’s setting.

- Consult the settings’ list (page 34).

On commissioning (or the case of error 10), the electrical
backup heaters are liable to start up even if the outside
temperature at the time is above the heaters’ trigger
temperature.

The regulating system uses an average initial outside
temperature of 0°C and requires some time to update
this temperature.

To mitigate this situation, the sensor must be connected
correctly. Re-initialise parameter 8703 (implementation
level, consumer diagnostic menu).

2.13 Conguring the room thermostat

3.3 Temperature control

The heat pump’s operation is subject to the temperature
control.

The set temperature for the water in the heating circuit
is adjusted according to the outside temperature.

The temperature control may be chosen automatically
by the machine (self-adaptation) or set manually by the
installer (Parameters 720, 721 and 726).

If there are thermostatic valves on the installation, these
must be fully open or adjusted for higher than the normal
set temperature.

3.3.1 Manual adjustment

During installation, the temperature control must be
parametered according to the heat emitters and the
dwelling’s insulation.

The temperature control’ curves (gure 41) refer to an
ambient setting of 20°C.

The slope of the temperature control (parameter

720) determines the impact of the variations in the
outside temperature on the initial heating temperature
variations.

The higher the slope, the more a slight reduction in the
outside temperature causes a signicant increase in the
initial water temperature in the heating circuit.

The off-set in the temperature control (parameter 721)
alters the initial temperature of all the curves, without
altering the slope (gure 42).

The corrective actions in the case of any inconvenience
are detailed in the table (gure 43).

3.3.2 Self-adaptation

When this function is active (parameter 726), the
temperature control are automatically adjusted; it is
therefore futile to alter the slope or the off-set in the
temperature control (parameters 720 and 721).

When this function is rst activated, the end user
may experience some inconvenience for a few days.
This period of no more than a week is required by
the regulator to determine the slope and off-set in the
temperature control.

We advise against changing the temperature settings
during this period.

The following instructions must be observed for the self­adaptation system to operate correctly :

- A room thermostat must be connected.

- The inuence of the ambient temperature" (parameter

750) must be set between 1 and 100%.

- Depending on the installation, the room thermostat may
have a greater or lesser inuence on the temperature
control.

- The room in which the room thermostat is installed
must not contain any thermostatic valves. If this is the
case, the valves must be open fully.
