1 package: Outside unit
1 package: hydraulic module and outdoor sensor
1.2 Definitions
Split: The heat pump consists of two elements (anoutside unit for outside and a hydraulic module forinside the dwelling).
Air/water: The surrounding air is the energy source.This energy is transmitted to the water in the heatingcircuit by the heat pump.
Inverter: the fan and compressor speeds aremodulated according to the heating requirements.
This technology enables you to save on energy andoperate on a single-phase power supply, whateverthe heat pumps output, by avoiding heavy intensitieson start-up.
COP (coefficient of performance): this is therelationship between the energy transmitted to theheating circuit and electrical energy consumed.

1.6 Operating principle
The heat pump transmits the energy contained in thesurrounding air into the dwelling to be heated.
The heat pump consists of four main elements, inwhich a refrigerant fluid (R410A) circulates.
- In the evaporator (rep. 13, fig 7, page 11): Theenergy is taken from the surrounding air and istransmitted to the refrigerant. Because it has a lowboiling point, it changes from the liquid state to thevapour state, even in cold weather (down to -15 Coutside temperature).
- In the compressor (rep. 10, fig 7, page 11): The
vaporised refrigerant brought to high pressure andtakes on more calories.
- In the condenser (rep. 15, fig 8, page 12): Theenergy in the refrigerant is transmitted to theheating circuit. The refrigerant returns to liquidstate.
- In the expansion valve (rep. 9, fig 7, page 11): Theliquefied refrigerant is brought back to low pressureand returns to its initial temperature and pressure.
The heat pump is equipped with a controller, whichcontrols the internal temperature based on theoutside temperature measurement and governed bythe temperature control.
The room thermostat (optional) provides a correctiveaction for the temperature control
The hydraulic module is equipped with an electricback-ups system, which is triggered to provideadditional heat during the coldest periods.
Regulation functions
- The heating circuits initial temperature is controlledby the temperature control.
- The power of the outside unit is modulatedaccording to initial heating temperature via theinverter compressor.
- Control of the electric back-up heating.
- The daily timer program enables you to define theperiods for comfortable or reduced ambienttemperature.
- Summer/winter mode switchover is automatic.
- Control of the supplementary boiler* (the electricback-ups are deactivated).
- The room thermostat* (optional) provides acorrective action for the temperature control
- Control of a second heating circuit*.
- Domestic hot water: Heating time programme,control of the operation of the DHW circulationpump.
- Control of swimming pool heating*.
Protection functions
- Anti-legionella cycle for domestic hot water.
* I f the heat pump is equipped with optionalequipment and the associated kits.

Domestic hot water (DHW) operating principle
Two domestic hot water (DHW) temperatures can beparametered: comfort temperature (line 1610 to60 C) and reduced temperature (line 1612 to 40 C).
Setting for reduced temperature can be useful toprevent the DHW from switching on too often and fortoo long during the day.
The production of domestic hot water (DHW) is
triggered when the temperature in the tank falls 7C(setting from line 5024) below the set temperature.
The heat pump produces the domestic hot water,which is then supplemented, if required, by electricalbackup heating from the tank.
Depending on how the parameter (1620) is set,comfort temperature can be reached 24h/day or onlyat night or depending on the heat pump programme.
If the contract concluded with the energy providerincludes a subscription to day/night tariff, theelectrical backup is subordinate to the supplierspower tariff and the comfort temperature may only be
reached at night.
If no particular contract is concluded, the comforttemperature can be reached at any time, includingduring the day
The production of DHW takes priority over heating;nevertheless the production of DHW is controlled bycycles that control the times assigned to the heatingand the product ion of DHW in the event o f simultaneous demand.
A DHW boost function is available on the front ofthe user interface (see ref. 1, fig. 39, p 31).
This DHW boost enables the DHW to be heated tothe comfort temperature at any time during the day.The boost function is cancelled automatically whenthe demand for hot water has been met.
If the heating installation is equipped with a DHWcirculation pump, the pumps operation during DHWcycles can be parametered.
Anti- legionella cycles can be programmed.

2 Installation
2.1 Regulation installation andmaintenance conditions
The appliance must be installed and the maintainedby an approved professional in accordance with the
prevailing regulations and code of practice, inparticular:The legislation on the handling of refrigerants.
2.2 Unpacking and reservations
2.2.1 Receipt
Carefully check, in the carriers presence, thegeneral appearance of the appliances and checkthat the outside unit is not laid on its side or back.
In the case of any dispute, state any appropriate
reservations to the carrier in writing within 48 hoursand send a copy of this letter to the After-Salesservice.
2.2.2 Handling
The outside unit should not be laid on its side or backduring transport.
Laying the unit down during transport is likely todamage the internal tubes and the compressorsuspensions.
Any damage caused by transportation of the unitlying down is not covered by the warranty.
If necessary the outside unit may be tilted only duringmanual handling (to go through a door or use astaircase).
This operation must be conducted very carefully andthe appliance must be immediately restored toupright position.
2.2.3 Accessories provided
Accessor ies provided wi th the outs ide uni t(figure 10).
Accessories provided with the hydraulic module
(figure 11)
2.3 Installation position
The choice of the posit ion for instal lat ion isparticularly important insofar as any later movementis a delicate operation requiring the intervention of aqualified person.
Choose the site of the outside unit and the hydraulicmodule after discussion with the customer.
Observe the maximum and minimum distancesbetween the hydraulic module and the outside unit
(Figure 13); the guarantee of the performances andthe systems service life depend on this.

2.6 Refrigeration connections
F This appliance uses refrigerant R410A.
Comply with the legislation for handling refrigerationfluids.
2.6.1 Rules and precautions
After every intervention on the refrigeration circuitand before final connection, take care to replace theplugs in order to avoid any pollution from therefrigeration circuit.
Tools
- Set of manometers with hoses exclusively reservedfor HFCs (Hydrofluorocarbons).
- Vacuum pump specially for HFCs.
- Provision on using tools that have been in contactwith HCFCs (R22 for example) or CFCs.
- Use of a traditional vacuum pump is authorized if,and only if, it is fitted with a non-return valve on the
suction side.The manufacturer declines any liability with regard tothe guarantee if the above instructions are notobserved.
Flared connections
F Lubrication with mineral oil (for R12, R22) isforbidden.
- Only lubricate with polyolester refrigeration oil(POE). I f POE is not ava i lab le , f i t wi thoutlubrication.
B r a z in g o n t h e r e f ri g e r at i o n c i r c u i t ( i f necessary)
- Silver brazing (40% minimum recommended).
- Brazing only under dry nitrogen internal flux.
To eliminate any filings in the pipes, use dry nitrogento avoid in troducing any humid i ty that mayadversely affect the appliances operation. Ingeneral, take every precaution to avoid humiditypenetrating into the appliance.
Proceed to insulate the gas and liquid pipes to avoidany condensation. Use insulating sleeves resistant
to temperatures over 120C. In addition if thehumidity level in the areas where the refrigerationpipes pass risks exceeding 70%, protect the pipeswith insulating sleeves. Use a sleeve thicker than15mm if the humidity reaches 80%, and a sleevethicker than 20mm if the humidity exceeds 80%. Ifthe recommended thicknesses are not observedu nd e r t h e c o nd i ti o ns d e sc r ib e d a b ov e ,condensation wil l form on the surface of theinsulation material . Lastly, take care to useinsulating sleeves whose thermal conductivity is0.045 W/mK or less when the temperature is 20C.The insulation must be impermeable to resist the
passage of steam during the defrosting cycles(fibreglass wool is prohibited).
2.6.2 Refrigeration connections
The outside unit must be connected to the hydraulicmodule wi th copper p ipes and connect ions(refrigeration quality), insulated separately.
Comply with the pipe diameters and the permittedpipe lengths (figure 13).
T h e m i n i m u m l e n g t h o f t h e r e f r i g e r a t i o n

The appliance will be excluded from guarantee if it isused with refrigeration connections less than 5mlong (models 080, 095, 128, 155).
Manipulate the pipes and take them through wallswith protective plugs in place.
If the distance between the outside unit and thehydraul ic module exceeds the length of themaximum conduits indicated in the table, anadditional charge of R410A must be loaded.
The quantity of R410Aadded must be adapted to the
length of the refrigeration circuit in order to the heatpumps per fo rmance wi thout damaging thecompressor (figure 23).
2.6.3 Creating the flarings
- Cut the pipe to an appropriate length with apipe-cutter without deforming it.
- Carefully deburr it, holding the pipe towards thebottom to avoid introducing filings into the pipe.
- Remove the flared connection nut situated on thevalve to be connected and slip the pipe into the nut.
- Proceed to flare, letting the pipe overflow the flaring
tool.- After flaring, check the condition of the workingradius (L). This must not show any scratch or traceof any fracturing. Also check the dimension (B).

2.7 Filling the installation with gas
F This operation is reserved for installersfamiliar with the legislation for handlingrefrigeration fluids.
F Creating a vacuum with a vacuum pump isessential.
F Never use equipment used beforehand withany refrigerant other than a HFC.
2.7.1 Creating a vacuum and filling the
refrigeration connections with gas
(see figure 22).
- Remove the protective plugs (B) from the charginghole (Schrader) in the gas valve (large diameter).
- Connect the blue hose (on the side with a valvepusher in good cond i t ion ) f rom the se t o f 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 15minutes after reaching the vacuum.
- Close the blue valve on the set of manometers andt he n s to p t he v ac uu m p um p w i t h o u tdisconnecting any of the hoses in place.
- Wait 10 minutes. If the pressure rises during this10-minute period, there is a leak in the circuit. Traceit 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 valvecontrols.
F If an additional charge is requires, add theadditional charge before filling the hydraulicmodule with gas. Please refer to the section(Additional charge, page 22).
- First of all fully open the small valve and then thelarge one using a hex key (counterclockwisedirection) without forcing excessively against thestop.
- Remove the blue hose rapidly.
- Ref i t the 2 p lugs and t igh ten them to therecommended tightening torque (see figure 21).
The outside unit does not contain any additionalrefrigerant, enabling the installation to be purged.
Flushing is strictly forbidden.
2.7.2 Sealing test
Once the refrigeration circuit has been gassed asdescribed above, check that all the refrigerationconnectors are gas-tight:
6 connectors for models 050 and 065, 5 connectorsfor model 080 and 4 connectors for models 095, 128and 155.
The seal ing test must be performed with anapproved gas detector.
If the flarings have been made correctly, there shouldbe no leaks.
F If there is a leak, make the connection again.

2.7.3 Additional charge
The charge in the outside units corresponds to themaximum distances between the outside unit andthe hydraulic module defined in Figure 13. If thedistances are greater, an additional charge of R410Ais required. The additional charge depends on thedistance between the outside unit and the hydraulicmodule for each type of appliance (Fig. 23). Theadditional charge of R410A must necessarily bemade by an approved refrigeration engineer.
Example for a heat pump model 155An outside unit 32m away from the hydraulic modulewill require an additional charge of:
Additional charge = (32 - 20) x 40 = 480 g
The charge must be introduced after creating thevacuum and before the hydraulic module is filled withgas, as follows:
- Disconnect the vacuum pump (yellow hose) andconnect a bottle of R410A instead in the fluidextraction position.
- Open the bottles valve.
- Bleed the yellow hose by loosening it slightly on themanifold side.
- Place the bottle on scales with a minimum accuracyof 10g. Note the weight.
- Carefully open the blue valve slightly and check thevalue shown on the scales.
- As soon as the value displayed has dropped by thevalue for the calculated additional charge, close thebottle and disconnect it.
- Then rapidly disconnect the hose connected to theappliance.
- Proceed to fill the hydraulic module with gas.
F Warning
Only use R410A!
Only use too ls su i tab le fo r R410A (se t o f
manometers).
Always charge in the fluid phase.
Never exceed the length or the maximum differencein level.

External faults the heat pump
Any component of carryforward of informat ion(thermostat, pressure switch, etc.) may signal anexternal problem and stop the heat pump.
- Connect the safety component to input EX6.
230 V on input EX6 = stoppage of heat pump (thesystem displays Error 369).
2.10 Outdoor sensor
The outdoor sensor is required for the heat pump tooperate correctly.
Consult the fitting instructions on the sensorspackaging.
Place the sensor on the coldest part, generally thenorthern or north-eastern side.
In any case, it must not be exposed to the morningsun.
It must be installed so as to be easily accessible butat least 2.5m from the f loor.
It is essential that it avoid any sources of heat suchas flues, the upper parts of doors and windows,proximity to extraction vents, the underneath of
balconies and under-eave areas which would isolatethe sensor from variat ions in the outside airtemperature.
- Connect the outdoor sensor to the M and B9terminals on the heat pump control board (fig. 38,p. 29).
2.11 Room thermostat and/or remotecontrol
The room thermostat (remote control) is optional.
Consult the fitting instructions on the sensorspackaging.
The sensor must be installed in the living room areaon a very uncluttered wall , 1.5m above the floor.
Avoid di rect sources of heat (chimney/f lue,te levi s ion, cook ing hobs) , d raugh ty a reas(ventilation, door, etc.).
Air leaks in the seals in the constructions are oftentranslated into cold air blowing through the electricalconduits. Lag the electrical conduits if there is a cold
draught on the back of the IR sensor.

2.12 Start-up
- Close the installations main circuit breaker.
On first commissioning (or in winter), in order to allowthe compressor to pre-heat, engage the installat ionsmain circuit breaker (power supply to the outsideunit) some hours before starting up the tests.
- Engage the heat pumps ON/OFF button.
When the power is switched on and every time that
the ON/OFF button is switched off and then switchedon again, the outside unit will take approximately 4minutes to start up, even if the setting is requestingheating.
- Make all the specific adjustments to the setting(configuring the installation).
- Press the key
- Hold downthe key for 3s and select the level of
access used with the aid of the knob .
- Confirm with the key
- Parameter the heat pumps setting
- Consult the settings list (page 34).
On commissioning (or the case of error 10), theelectrical backup heaters are liable to start up even ifthe outside temperature at the time is above theheaters trigger temperature.
The regulating system uses an average initialoutside temperature of 0C and requires some time
to update this temperature.To mitigate this situation, the sensor must beconnected correctly. Re-initialise parameter 8703(implementation level, consumer diagnostic menu).
2.13 Configuring the room thermostat

3.2 Room thermostat (Option)
3.3 Temperature control
The heat pumps operation is subject to thetemperature control.
The set temperature for the water in the heatingci rcu i t is ad justed accord ing to the outs idetemperature
T he t e mp era tu re c o nt rol m a y b e c h os e nautomatically by the machine (self-adaptation) or setmanually by the installer (Parameters 720, 721 and726).
If there are thermostatic valves on the installation,these must be fully open or adjusted for higher thanthe normal set temperature.
3.4 Manual adjustment
During installation, the temperature control must beparametered according to the heat emitters and thedwellings insulation.
The temperature control curves (Fig. 41) refer to anambient setting of 20C.
The slope of the temperature control (parameter720) determines the impact of the variations in theou ts ide tempera tu re on the in i t ia l hea t ingtemperature variations.
The higher the slope, the more a slight reduction inthe outside temperature causes a significantincrease in the initial water temperature in theheating circuit.
The off-set in the temperature control (parameter721) alters the initial temperature of all the curves,
without altering the slope (Fig. 42).
The co r rec t i ve ac t i ons i n the case o f anyinconvenience are detailed in the table (Figure 43).
3.5 Self-adaptation
When this function is active (parameter 726), thetemperature control are automatically adjusted; it istherefore futile to alter the slope or the off-set in thetemperature control (parameters 720 and 721).
When this function is first activated, the end usermay experience some inconvenience for a few days.
This period of no more than a week is required by theregulator to determine the slope and off-set in thetemperature control.
We advise against changing the temperaturesettings during this period.
The following instructions must be observed for theself-adaptation system to operate correctly:
- A room thermostat must be connected.
- The inf luence of the ambient temperature"(parameter 750) must be set between 1 and 100%.
- Depending on the installation, the room thermostatmay have a greater or lesser influence on the
temperature control.- The room in which the room thermostat is installedmust not contain any thermostatic valves. If this isthe case, the valves must be open fully.
