1 Description of the unit

1.1 Package

• 1 package: Outside unit

• 1 package: hydraul ic module and exter iortemperature sensor

1.2 Definitions

Split: The heat pump consists of two elements (anexternal 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 pump's 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 low boiling point, it changes fromthe liquid state to the vapour state, even in coldweather (down to -15 °C external temperature).

- In the compressor (rep. 10, fig 7, page 11): Thevaporised 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 theexternal 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 circuit's initial temperature is controlledby the temperature control.

- The power of the Outside unit is modulatedaccording to initial heating temperature via the"inverter" 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.

* If 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 to 60°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) istriggered 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 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 supplier'spower tariff and the comfort temperature may only bereached 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 ofsimultaneous 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 pump's operation during DHWcycles can be parametered.

Anti-legionella cycles can be programmed.

2.6 Refrigeration connections

� 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 thesuction side.

The manufacturer declines any liability with regard tothe guarantee if the above instructions are notobserved.

• Flared connections

� Lubrication with mineral oil (for R12, R22) isforbidden.

- Only lubricate with polyolester refrigeration oil(POE). I f POE is not avai lable, f i t wi thoutlubrication.

• Braz ing on the refr igerat ion circui t ( i fnecessary)

- Silver brazing (40% minimum recommended).

- Brazing only under dry nitrogen internal flux.

• To eliminate any filings in the pipes, use dry nitrogento avoid introducing any humidity 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 temperaturesover 120°C. In addition if the humidity level in theareas where the refrigeration pipes pass risksexceeding 70%, protect the pipes with insulatingsleeves. Use a sleeve thicker than 15mm if thehumidity reaches 80%, and a sleeve thicker than20mm if the humid i ty exceeds 80%. I f therecommended thicknesses are not observed underthe conditions described above, condensation willform on the surface of the insulation material. Lastly,take care to use insulating sleeves whose thermalconductivity is 0.045 W/mK or less when thetemperature is 20°C. The insulation must beimpermeable to resist the passage of steam duringthe defrosting cycles (fibreglass wool is prohibited).

2.6.2 Refrigeration connections

The external unit must be connected to the hydraulicmodule wi th copper pipes and connect ions(refrigeration quality), insulated separately.

Comply with the pipe diameters and the permittedpipe lengths (figure 13).

The minimum length of the refr igerat ionconnections is 5m for correct operation.

The appliance will be excluded from guarantee if it isused with refrigeration connections less than 5mlong.

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

If the distance between the external 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 R410A added must be adapted to thelength of the refrigeration circuit in order to the heatpump's per formance 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 flaringtool.

- 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

� This operation is reserved for installersfamiliar with the legislation for handlingrefrigeration fluids.

� Creating a vacuum with a vacuum pump isessential.

� 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 condi t ion) f rom the set ofmanometers (manifold).

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

- Create a vacuum until the residual pressure in thecircuit 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 andthen s top the vacuum pump w ithoutdisconnecting 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.

� 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 plugs and t ighten them to therecommended tightening torque (see figure 21).

The external 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 sealing test must be performed with anapproved gas detector.

If the flarings have been made correctly, there shouldbe no leaks.

If there is a leak, make the connection again.

2.7.3 Additional charge

The charge in the external units corresponds to themaximum distances between the external unit andthe hydraulic module defined in Figure 13.

If the distances are greater, an additional charge ofR410A is required.

The additional charge depends on the distancebetween the external unit and the hydraulic modulefor each type of appliance (Fig. 23)

The additional charge of R410A must necessarily bemade by an approved refrigeration engineer.

• Example for a heat pump model 155

An external 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 bottle's 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.

� Warning

• Only use R410A!

• Only use too ls su i tab le for R410A (set ofmanometers).

• Always charge in the fluid phase.

• Never exceed the length or the maximum differencein level.

2.8 Connecting the heating circuithydraulically

2.8.1 General

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

The heating circulating pump is built into thehydraulic module.

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

The diameter of the pipes between the hydraulicmodule and the heating collector must be at least 1inch (24x36mm).

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

Use union connectors to facilitate removing thehydraulic module.

Preferentially use connection hoses to avoidtransmitting noise and vibrations to the building.

Connect the drains from the drain valve and thesafety valve to the main sewer system.

Reminder : Sea l every th ing when f i t t ing inaccordance with prevailing trade practice forplumbing work:

- Use suitable seals (fibre seals, o-rings).

- Use Teflon tape or hemp.

- Use sealing paste (synthetic depending on thecase).

The use of glycol is not necessary.

If you are using a glycol/water mix, provide for anannual check on the quantity of glycol.

In certain installations, the presence of differentmetals can cause corrosion problems; the formationof metal particles and sludge in the hydraulic circuitis then seen.

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

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

2.8.2 Rinsing out the installation

Before connecting the hydraulic module to theinstallation, rinse out the heating system correctly toel iminate any part ic les that may affect theappliance's correct operation.

Do not use solvents or aromatic hydrocarbons(petrol, paraffin, etc.).

In the case of an old installation, provide a sufficientlylarge decanting pot with a drain on the return fromthe boiler and at the lowest point in the system inorder to collect and remove the impurities.

Add an alkaline product to the water and adispersant.

Rinse the installation several times before filling itdefinitively.

2.8.3 Filling and purging the installation

Check the pipe fixings, the tightness of theconnectors and the stability of the hydraulic module.

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

Proceed to fill the installation.

Do not operate the circulating pump while filling.Open all the drain valves in the installation and thebleed valve for the hydraulic module to remove theair contained in the conduits.

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

If the pressure is lower than 0,5 bar, the Heat Pumpstops and posts error 369.

Check that the hydraulic circuit has been purgedcorrectly.

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

After the "Start-up" stage (see p. 30), once themachine has started, purge the hydraulic moduleagain (2 litres of water).

• Faults outside the heat pump

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

E.g.: A safety thermostat on the heating floor will stopthe heat pump if the temperature in the floor is toohigh

- Connect the safety component to input EX6.

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

2.10 External sensor

The external sensor is required for the heat pump tooperate correctly.

Consult the fitting instructions on the sensor'spackaging.

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 floor.

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 ofbalconies and under-eave areas which would isolatethe sensor from variations in the external airtemperature.

- Connect the external 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 sensor'spackaging.

The sensor must be installed in the living room areaon a very uncluttered wall, 1.5m above the floor.

Avoid direct sources of heat (chimney/f lue,te lev is ion , cook ing hobs) , d raughty areas(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 colddraught on the back of the IR sensor.

Figure 38 - Connections to the heat pump regulator (accessories and options)

• Installation equipped with two room thermostats

- Connect each of the sensors to one of the CL+ orCL- terminals on the heat pump control board(fig. 38, p. 29) using the connector supplied.

• Installation equipped with a room thermostat and aremote control

- Connect the sensor to one of the CL+ or CL-terminals on the heat pump control board (fig. 38,p. 29).

- Connect the remote control to the other CL+, CL-terminals and to G+.

2.12 Start-up

- Close the installation's main circuit breaker.

On first commissioning (or in winter), in order to allowthe compressor to pre-heat, engage the installation'smain circuit breaker (power supply to the externalunit) some hours before starting up the tests.

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

When the power is switched on and every time thatthe ON/OFF button is switched off and then switchedon again, the external 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 down the key for 3s and select the level of

access used with the aid of the knob .

- Confirm with the key

- Parameter the heat pump's 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 external temperature at the time is above theheaters’ trigger temperature.

The regulating system uses an average initialexternal temperature of 0°C and requires some timeto 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

Room thermostat T55

To configure the room thermostat and connect it tothe appropriate heating zone:

- Hold down the presence key for more than 3seconds. The room thermostat displays RU and anumber flashes.

3.3 Temperature control

The heat pump's operation is subject to thetemperature control.

The set temperature for the water in the heatingcircuit is adjusted according to the externaltemperature

The tempera ture cont ro l may be chosenautomatically 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 thedwelling's insulation.

The temperature control' curves (Fig. 41) refer to anambient setting of 20°C.

The slope of the temperature control (parameter720) determines the impact of the variations in theexternal temperature on the in i t ia l heat ingtemperature variations.

The higher the slope, the more a slight reduction inthe external 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 cor rec t ive ac t ions in the case of 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 thetemperature 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.
