1. GENERAL RECOMMENDATIONS

Please read the following safety precautions very carefully before installing the unit.

1.1. SAFETY DIRECTIONS

Follow the safety rules in forces when you are working on your appliance.

The installation, commissioning and maintenance of these units should be performed by qualied personnel

having a good knowledge of standards and local regulations, as well as experience of this type of equipment. This appliance has not been designed for use by persons (including children) with reduced physical, sensorial

or mental faculties or by persons without any experience or knowledge of heating systems, unless they act under the safety and supervision of a responsible person or have received prior training concerning the use of the appliance.

Children should be supervised to ensure that they do not play with the appliance. The unit should be handled using lifting and handling equipment appropriate to the unit's size and weight. Any wiring produced on site must comply with the corresponding national electrical regulations. Make sure that the power supply and its frequency are adapted to the required electric current of operation,

taking into account specic conditions of the location and the current required for any other appliance

connected to the same circuit. The unit must be EARTHED to avoid any risks caused by insulation defects. It is forbidden to start any work on the electrical components if water or high humidity is present on the

installation site.

1.2. WARNING

Cutoff power supply before starting to work on the appliance. When making the hydraulic connections, ensure that no impurities are introduced into the pipe work.

The manufacturer declines any responsibility and the warrantly becomes void if these instructions are not respected.

If you meet a problem, please call the Technical Department of your area.

If possible, assemble the compulsory or optional accessories before placing the appliance on its nal location.

(see instructions provided with each accessory).

In order to become fully familiar with the appliance, we suggest to read also our Technical Instructions.

The information contained in these Instructions are subject to modication without advance notice.

1.3. EQUIPEMENT SAFETY DATA

Safety Data R407C

Toxicity Low

In contact with skin

Liquid splashes or sprays may cause freeze burns. Unlikely to be hazardous by skin absorption. However, R407C may be slightly irritant and, if liquid, it has a strong degreasing effect. Flush contaminated skin areas with running water. If it comes into contact with fabrics, the liquid refrigerant will cause them to freeze and adhere to the skin. Carefully remove the contaminated clothing since it might adhere to the skin and cause freeze burns. Contact a doctor if the affected skin areas are reddened or irritated.

In contact with eyes

Vapours have no effect. Liquid splashes or sprays may cause freeze burns. In these cases rinse your eyes with running water or with a solution for eye lavages for at least 10 minutes. Immediately contact a doctor.

Ingestion

Very unlikely to occur. If this should be the case, it may cause freeze burns. Never induce vomiting. Keep the patient awake. Make him rinse his mouth with running water and make him drink about 1/4 of a litre. Immediately contact a doctor.

Inhalation

R407C: High concentration levels of its vapours in the air can produce an anaesthetic effect, including the loss of consciousness. Particularly severe exposures may cause heart arrhythmia and sometimes prove to be also fatal.

At high concentrations there is a danger of asphyxia due to a reduced oxygen content in the atmosphere. In these cases take the patient to the open air, in a cool place and keep him at rest. Administer oxygen, if required. Apply artificial respiration if breathing has ceased or if it has become irregular. In case of heart failure immediately apply cardiac massage. Immediately contact a doctor.

Further Medical Advice

A symptomatic and supportive therapy is generally suitable. A heart sensitisation has been observed in some cases, as a result of exposures to particularly high concentrations. In the presence of catecholamines (such as for example adrenaline) in the blood flow, it has increased the irregularity of the cardiac rhythm and then caused the heart failure.

Long-term exposure

R407C: A lifetime study which has been conducted on the effects inhalation may have on rats at 50,000 ppm has shown the onset of benign tumours of the testicle. These remarks suggest that there is no danger for human beings if they are exposed to concentrations below the occupational limits or equal to them.

Occupational exposure limits

R407C: Recommended limits: 1,000 ppm v/v 8 hours TWA.

Stability R407C: Not specified.

Conditions to avoid Use in the presence of exposed flames, red heat surfaces and high humidity levels.

Hazardous reactions

Possibility of violent reactions with sodium, potassium, barium and other alkaline substances. Incompatible materials: magnesium and all the alloys containing over 2% of magnesium.

Hazardous decomposition products

R407 C: Halogen acids deriving from thermal decomposition and hydrolysis.

General precautions

Avoid the inhalation of high concentrations of vapours. The concentration in the atmosphere shall be kept at the minimum value and anyway below the occupational limits. Since vapours are heavier than air and they tend to stagnate and to build up in closed areas, any opening for ventilation shall be made at the lowest level.

Breathing protection

In case of doubt about the actual concentration, wear breathing apparatus. It should be self-contained and approved by the bodies for safety protection.

Storage Preservation

Refrigerant containers shall be stored in a cool place, away from fire risk, direct sunlight and all heat sources, such as radiators. The maximum temperature shall never exceed 45°C in the storage place.

Protection clothes Wear boots, safety gloves and glasses or masks for facial protection.

Behaviour in case of leaks or escapes

Never forget to wear protection clothes and breathing apparatus. Isolate the source of the leakage, provided that this operation may be performed in safety conditions. Any small quantity of refrigerant which may have escaped in its liquid state may evaporate provided that the room is well ventilated.In case of a large leakage, ventilate the room immediately. Stop the leakage with sand, earth or any suitable absorbing material. Prevent the liquid refrigerant from flowing into drains, sewers, foundations or absorbing wells since its vapours may create an asphyxiating atmosphere.

Disposal

The best procedure involves recovery and recycle. If this is not possible, the refrigerant shall be given to a plant which is well equipped to destroy and neutralise any acid and toxic by-product which may derive from its disposal.

Combustibility features R407C: Non flammable in the atmosphere.

Containers

If they are exposed to the fire, they shall be constantly cooled down by water sprays. Containers may explode if they are overheated.

Behaviour in case of fire

In case of fire wear protection clothes and self-contained breathing apparatus.

2. INSPECTION AND STORAGE

THE WARRANTY SHALL BE NULL AND VOID IN THE EVENT

OF NON-COMPLIANCE WITH ANY OF THE ABOVE CONDITIONS.

This range of air/water Aqu@ Scop HT (High Temperature) appliances offers the special feature of producing hot water at 65° C at outdoor temperatures between 0° C and -20° C, while guaranteeing a high COP.

Between 0°C and +42°C, the temperature of the hot water produced varies between 65°C and 55°C for the Heating mode and is maintained at 60°C for the Domestic Hot Water (DHW) mode.

Consequently, this Aqu@ Scop HT system is ideally suited to replace a traditional hot water boiler in producing DHW without alterations to the rest of the system.

This technology uses two-stage compressors connected to a patented refrigeration circuit.

This technology ensures remarkably accurate "capacity supplied/heating needs" matching due to its ability to run each compressor independently. Depending on the demand for heating capacity and the operating temperature of heat emitters (i.e. radiators, etc.) the Aqu@ Scop HT regulator selects either the small or large compressor to operate on its own or in a two-stage mode.

10. REFRIGERATION AND HYDRAULIC DIAGRAM

SEE APPENDIX

11. INSTALLATION

The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a collapse with dangerous consequences for personnel and property. In such an event, the warranty shall be null and void.

Unit operation depends on air temperature. Any recycling of air extracted by the fan lowers the

air intake temperature across the exchanger ns and alters the standard operating conditions.

The outdoor unit must be installed outdoors with sufcient surrounding clearance to enable unobstructed

air circulation through the appliance and access for maintenance work.

In the case of the unit being sited in areas exposed to high winds, you must avoid the wind hitting the fan blowing surface areas directly to avoid any risk of recycling cooled air. Exchanger fan operation can be disrupted by strong winds, which can cause de-icing problems and fan malfunctions.

The arrows show the direction of air circulation through the appliance. (Refer to the § ATTACHEMENT TO THE GROUND, page 11).

Depending on temperature and outdoor air humidity conditions, water vapour contained in the air can

condense on the nned heat exchanger and even form ice under low outdoor temperature conditions (around

< 5°C). This condensate water and defrosted water runs off via outlets provided under the exchanger. To aid water run-off and avoid frozen water remaining in the appliance in winter, we recommend that it is mounted at a height of around 10cm off the ground by installing the ant-vibration mounting kit. In this way, condensate and defrosted water can run off freely and be absorbed into the ground or channelled to a basin built under the appliance in order to protect the environment.

In areas where outdoor temperatures fall below 1°C, the system can be equipped with a condensate antifreeze protection system (e.g. a heated pipe sheath, Not supplied).

In order to contain noise levels, we equip our appliances with quiet fans and encase the technical compartment in sound-proofed panels. However, noise levels can be reduced even further by following a few installation precautions:

² Do not install the appliance near a bedroom window. Avoid locating the appliance in a corner

(increased reverberated noise).

² Install the rubber pads supplied or anti-vibration pads (available as an option) under the appliance. ² Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure-

borne noise transmission).

11.2. CLEARANCE

When choosing the location for the appliance, take care to leave sufcient free clearance on all sides to

ensure easy access for maintenance work. The minimum free clearance dimensions indicated must be observed to ensure both proper system operation and allow access for maintenance and cleaning.

11.3. ATTACHEMENT TO THE GROUND

Unit mounting measurements are shown on the drawing opposite. A slope of 1 cm/m should be created to assist rainwater drainage.

Vibration dampers must be tted during

installation to overcome any risks of vibration being transmitted due to direct contact with a rigid support surface.

12. HYDRAULIC LINKS

When choosing and installing water pipes, you must consult and observe all current local standards, regulations and instructions.

12.1. GENERAL RECOMMENDATIONS

You must design the pipe network with the minimum number of bends and keep the number of changes in height to the strict minimum. This will reduce installation costs and ensure optimum system performance. The pipe network must include:

² A vibration elimination system (e.g.: link hoses available as an accessory) on all pipes connected to

the appliance in order to reduce vibrations and noise transmitted to the building fabric.

² Stop cocks to isolate the hydraulic circuit during maintenance. ² Manual or automatic bleed valves at the highest point on the water circuit. ² A suitable system for maintaining water pressure in the circuit (expansion tank). ² The installation of thermometers and pressure gauges on the heat exchanger inlet and outlet to

facilitate day-to-day controls and system maintenance.

12.1.1. ANTI-CLOGGING PROTECTION

When installing Aqu@ Scop HT appliances in existing water circuits,

a sludge trap and a removable mesh lter should be installed

upstream of the appliance.

To avoid any risk of foreign bodies entering the appliance and to guarantee operating performance, WE STRONGLY RECOMMEND THAT YOU INSTALL THE WATER FILTER ACCESSORY on the Aqu@ Scop HT inlet pipe.

To ensure that the system operates correctly you must use suitably sized and properly routed pipes for the hydraulic links between the Heat pump and the mains network.

The volume of water contained in the installation must be sufcient to avoid any possibility of the compressor

"short cycling", and to guarantee adequate compressor running times in order to provide optimum service life and to ensure that de-icing cycles are performed properly.To ensure the Aqu@ Scop HT functions

efciently, available installation water volume must be:

12.1.2. MINIMUM HEATED WATER VOLUME REQUIREMENTS – BUFFER TANK.

200l < available water volume < 250l

When water circulation through heat emitters can be interrupted (thermostatic radiator valves closed) or the heating supply halted, you must ensure that:

² The heat pump maintains its nominal water ow, ² The heat pump operates in a loop with a minimum available volume of 200 litres.

The use of a 3-speed circulation pump enables water ow through the appliance to be adapted to pressure

losses in the system. (Pump supplied set on Max position).

Layout 2: Application with room by room regulation

This layout is recommended for heating installations with wide operating water ow variations (radiator

thermostatic valves present in the system). We strongly recommend including the buffer tank (2) as it guarantees that the heating loop capacity is higher than the minimum volume when the maximum number of thermostatic valves are closed.

The ow regulating valve (11) is used to balance the ow in heating mode and domestic hot water production

mode to always ensure optimum Aqu@ Scop HT operation.

12.2.2. AQU@ SCOP HT AS A BOILER SUBSTITUTE

We recommend the tting of a zone valve to avoid heat losses via the boiler when the Aqu@ Scop HT is working on its own.

All system devices should be of a suitable size to limit pressure losses.

Water ow within the heating circuit is normally driven by the circulation pump already present in the

installation (recommended solution) or by the Aqu@ Scop HT's circulation pump. In this case, you must

ensure that the circulation pump generates sufcient water pressure.

There is no need to replace the existing buffer tank on the circuit to take account of the small volume of water added by the presence of the Aqu@ Scop HT.

IMPORTANT: the hydraulic kit available as an option enables you to prepare the circuit for connection to the Aqu@ Scop HT in accordance with our recommendations. The hydraulic kit is available with or without zone valves.

12.2.3. AQU@ SCOP HT – DUAL ZONE INSTALLATION (UNDER-FLOOR HEATING + RADIATORS)

The Aqu@ Scop HT manages a radiator zone (high temperature, zone 2) and an under-oor heating zone (low temperature, zone 1) by way of an under-oor temperature outlet probe, a modulating 3-way valve

(230V 3 phase motor) and a water circulation pump for each zone.

Each zone can be controlled by a dedicated ambience terminal, which then enables the Aqu@ Scop HT to manage 2 independent water laws. When the radiators zone is not in operation, the Aqu@ Scop HT switches

over automatically to the under-oor heating water law, and thereby optimises the seasonal COP for the

entire installation.

Page 21

English

Aqu@Scop HT V2

The Aqu@ Scop HTmust not run on a network with open loops, likely to cause incidents related to oxygenation, or with non treated table water.

If the water circuit is to be drained for a time exceeding one month, the circuit must be fully charged with nitrogen to prevent any risk of corrosion by differential venting.

The manufacturer is not liable for recommendations in terms of water treatment (call a specialized company).

However, this matter has a critical nature, and particular care must be given to ensure that the type of treatment applied is effective.

The liability of the manufacturer or its representative will not be sought when non treated water or non compliant quality water is used.

12.3. WATER QUALITY

The water must be analyzed; the hydraulic network system installed must include all elements necessary

for water treatment: lters, additives, intermediate exchangers, drain valves, vents, check valves, etc.,

according to the results of the analysis.

Using improperly treated or non treated water in the Aqu@ Scop HT may cause scaling, erosion, corrosion or algae or sludge deposits in the exchangers. Refer to a specialist skilled in water treatment to determine any treatment to apply. The manufacturer will not be held liable for damages caused when non treated or improperly treated water, demineralized water, salty water or sea water are used.

Apply the following guidelines :

² No NH4+ ammonium ions in the water, highly detrimental to copper. <10mg/l ² Cl- chloride ions are detrimental to copper with a risk of puncture by picking corrosion. <10mg/l. ² SO42- sulphate ions may cause perforating corrosion. < 30mg/l.

² No uoride ions (<0.1 mg/l) ² No Fe2+ and Fe3+ ions, particularly in case of dissolved oxygen. Fe< 5mg/l with dissolved oxygen

< 5mg/l. The presence of these ions with dissolved oxygen indicates corrosion of steel parts, likely to generate corrosion of copper parts under Fe deposits, particularly in the case of multitubular exchangers.

² Dissolved silica: silica is an acid element of water and may also cause corrosion. Content < 1mg/l. ² Water hardness: TH > 2.8K. Values between 10 and 25 may be recommended. This facilitates scaling

deposits likely to limit copper corrosion. Excess TH values may lead to clogging the pipes.

² TAC<100 ² Dissolved oxygen: Prevent any sudden change in the water's oxygenation conditions. Also, avoid

deoxygenating water by sparging inert gas as well as overoxygenating it by pure oxygen sparging. Disturbing oxygenation conditions destabilizes copper hydroxides and particle salting-out.

² Electrical Resistivity - Conductivity: The higher the resistivity, the slower the corrosion. Values above

3000 ohm/cm are preferred. A neutral environment favours maximum resistivity. For electrical conductivity, values around 200-600 S/cm can be recommended.

² pH: neutral pH at 20°C (7 < pH < 8)

Aqu@Scop HT V2

You must check water tightness and the cleanliness of the installation before connecting the Aqu@ Scop HT . For the Aqu@ Scop HT 's WATER INLET and OUTLET connections, you must install manual stop cocks with

the same diameter as the main pipe work. This will enable maintenance work to be carried out on the

Aqu@ Scop HT without having to bleed the entire system. A link valve with pressure tap kit is available.

The Aqu@ Scop HT must be protected by a water lter. When connecting this device to the Aqu@ Scop HT , take care to keep the water lter sieve pointing downwards. A sludge trap should be tted in the event of

high sludge build-ups.

WARNING!

Take care not to damage the hydraulic pipe links by applying too much tightening pressure. Use a second wrench to compensate for the tightening torque.

You should always use a counter-wrench for tightening valves.

To guarantee proper energy efciency and compliance with current standards, water pipes passing through

uninhabited zones should be properly lagged to retain heat. To achieve correct insulation with conductivity of 0.04 W/mK, lag the pipes with insulating material with a

radial thickness between 25mm and 30 mm.

THE MANUFACTURER'S WARRANTY IS VOID IF THE FILTER SUPPLIED WITH THE AQU@ SCOP HT IS

NOT INSTALLED TO PROTECT THE APPLIANCE

AN EXPANSION TANK ADAPTED TO THE VOLUME OF WATER IN THE INSTALLATION MUST BE INSTALLED.

It is important to ensure that the mains water supply pressure is sufficient to fill the installation.

Aqu@Scop HT V2

12.6. FILLING THE SYSTEM WITH WATER

Once the installation is complete and after having clean and rinsed out the circuit network, you must ll

the water circuit in accordance with current professional standards until you obtain the service pressure which will be:

0.5 bar < P. service < 2.5 bars.

The Aqu@ Scop HT is equipped with an electronic water pressure sensor. This can be viewed on the main P1 screen on the display, as well as on the Maintenance screens.

The water supply should come either from the mains network or from the Heat Pump or from any other point on the installation.

Check that the automatic bleed valve operates correctly.

You must completely bleed the circuit of all air to ensure efcient operation.

Close the inlet water valve once the hydraulic circuit is lled correctly.

The condenser water circuit is equipped with a vortex effect electronic ow meter. This device provides real-time readings of the installation's water ow and reassurance that this ow is adequate before starting the unit.

The appliance is also equipped with a group of safety devices including a valve set at 3 bars, and a manual relief valve.

Water ow can be viewed on screen P2 as well as on the Maintenance screens.

Use the water circulation pump speed selector to adjust the ow in the installation at the recommended

nominal value (Refer to the § PHYSICAL CHARACTERISTICS, page 7). Pressure drop of the installation must be situated in the circulator operating range.

The Aqu@ Scop HT controller manages domestic hot water production in accordance with the following operating modes:

² PERMANENT COMFORT MODE

Domestic hot water production has priority over heating except when the ambiance temperature / set temperature difference is greater than 2° C (Maximum one hour). Example: Set temperature = 20°C, Ambience < 18°C

² ECONOMY MODE

Domestic hot water is produced during off-peak hours (dry contact) or in accordance with times programmed in the controller. Option: Possibility to restart domestic hot water production outside off-peak hours if the water temperature has reached a programmable minimum temperature.

² IMMEDIATE DOMESTIC HOT WATER PRODUCTION

The Aqu@ Scop HT 's regulator enables domestic hot water production to be forced as required. At the end of the cycle, the system returns to its usual operating mode.

15.2. DOMESTIC HOT WATER PRODUCTION MODES

15.3. DOMESTIC HOT WATER HEATING FUNCTION ACTIVATION

The Legionnaires' Disease protection treatment managed by the Aqu@ Scop HT 's controller is fully programmable (frequency, temperature threshold, treatment length).

The PERMANENT COMFORT and ECONOMY modes place priority on thermodynamic heating. In the event of excessive demand for Domestic Hot Water Temperature that does not permit the compressor(s) to operate, the backup electric heating function is activated. In order to achieve energy savings, it is important to use the lowest possible set temperature points.

We recommend:

SEE APPENDIX

Operating parameters for these modes can be set via the display on the Aqu@ Scop HT .

16.2.1. BOOST MODE

The backup electric heating offers additional capacity when the demand for heating is higher than the capacity of the Aqu@ Scop HT. The aim is to maintain occupant comfort, while favouring thermodynamic operation for optimised performance.

The resistances are only activated below a certain outdoor temperature (values can be set for Stage 1, AEH1 and Stage 1+2, AEH1+AEH2) and only if the Aqu@ Scop HT regulation system detects a lack of capacity in compressor only mode (check on water temperature and ambient temperature).

Activation of the EMH Back-up switch on the heater switches the Aqu@ Scop HT into Back-up mode.

16.2.2. BACK-UP MODE

As opposed to Booster mode, this mode operates only when the user activates the EMH Back-up switch (this supposes an alarm on the Aqu@ Scop HT ). Outdoor temperature conditions are overridden and priority is no longer given to the thermodynamic mode but to the heating resistances that are nevertheless still controlled by the Aqu@ Scop HT .

17. BOILER RELIEF

17.1. ELECTRICAL CONNECTIONS

The boiler relief function uses the digital outputs of the in-line electric heater function to control the hot water boiler ON/OFF switch (Boiler dry contact switch) as well as a 3-way valve output (230V BRV). A switch should be wired to the ICS input to ensure operation in Back-up mode.

We strongly recommend the installation of the ambience terminal for effective operation of the Boiler Relief function. In the absence of an ambience terminal the Aqu@ Scop HT will be unable to optimise hot water boiler operation and this will lead to unnecessary energy consumption.

17.2. OPERATING MODES

Operating parameters for these modes can be set via the display on the Aqu@ Scop HT.

17.2.1. BOOST MODE

Hot water boiler operation is only authorised below a certain set outdoor temperature value and the appliance can also be placed in forced shutdown mode below a different outdoor temperature value. Just as the electric heater, the Aqu@ Scop HT continuously checks the water temperature and the ambient temperature to optimise compressor operation and to only start the hot water boiler when absolutely necessary.

The Aqu@ Scop HT can also be set to manage a heat curve on the hot water boiler higher than the temperature set for the appliance (65° C maximum).

17.2.2. BACK-UP MODE

Activation of the EMH switch (to be wired by the installer) or the Back-up parameter, via the "Boiler Relief" tab on the main menu of the Aqu@ Scop HT display, switches the system into Back-up mode and both outdoor temperature and ambient temperature conditions are overridden.

20.2. SIMPLIFIED START-UP PROCEDURE

20.2.1. MAIN SCREENS

20.2.2. INSTALLATION CONFIGURATION

First of all, certain installation parameters must be congured via the "Cong

installation" menu.

CI1 Conguration of the type of heating emitter: radiators or under-oor heating. Changing this parameter

automatically leads to changes in the water law parameters. It is very important to congure this

parameter before making any alterations whatsoever to the water law parameters and before starting the Aqu@ Scop HT for the rst time.

Page 40

English

Aqu@Scop HT V2

CI5 Refer to the § TIME AND DATE VERIFICATION, page 40.

CI6 Display buzzer authorisation in the event of an alarm (Default setting:

authorised).

CI3 Ambience terminal Activation/deactivation (Default setting: activated).

The temperature differential parameters in relation to the set ambient temperature control the starting and stopping of the Aqu@ Scop HT in terms of ambient temperature (even though the water law is also managed by ambient temperature conditions). As a default setting, the PAC will stop at the set ambient temperature + 1°C and restart at the set ambient temperature + 0.5°C (this enables the installation to anticipate any drop in ambient temperature and avoid excessive

temperature uctuations).

CI2 Outdoor temperature probe. This probe should not be installed

remotely.

CI4 Configuration of the remote all or nothing ON/OFF input. Refer to the Indoor unit wiring diagram.

In SUMMER/WINTER conguration, this input stops the Heating

function while maintaining the DHW function active (equivalent to the ambience terminal switching to OFF). NO (Normally Open) or NC

(Normally Closed) conguration is also possible.

In ON/OFF conguration, this input enables the Aqu@ Scop HT to be

stopped completely. When the boiler substitution function is activated, switching to OFF automatically activates the boiler. It is possible to

congure this input as Normally Open or Closed (Default setting: NO).

20.2.4. VERIFICATION OF COMMUNICATION WITH THE COMMUNICATING AMBIENCE TERMINAL

By default, the ambience terminal is declared in the regulator. This means that an alarm will be visible on the screen of the Aqu@ Scop HT a few seconds after the power supply is switched on, if the terminal is not connected. Proper terminal operation can be checked on screens TH1 to TH3.

All the terminal parameters are accessible via the "Ambience Terminal" menu in the main menu (key

Screens: TH0 to TH3.

20.2.5. COMPRESSOR SUMP HEATER FUNCTION ACTIVATION

After the rst power ON (compressors OFF), and for any outdoor air temperature, manually switch ON the compressor sump heaters.

Before starting the compressors, the sump heaters must be powered On for at least 2 hours in order to evaporate any liquid refrigerant that could be in the

compressors to ensure their lubrication at the rst start-up.

The screen TH0 appears when the terminal is deactivated (installation menu) or disconnected. This screen provides access to a set temperature to facilitate the inputting of water law offset values.

20.2.6. TIME AND DATE VERIFICATION

The time and the date are used to manage the:

² Alarm log. ² The DHW Legionnaires Disease protection function.

When a communicating ambience terminal is connected to the Aqu@ Scop HT, the time is automatically updated in the regulator. The date is managed solely by the regulator. At commissioning, check:

² The date, screen P4. Update as required in the "Cong installation" CI5

menu.

² The time (screen P4) if no ambient terminal is connected. Update as

required in the "Cong installation" CI5 menu.

General comments:

² If you have a doubt about a Aqu@ Scop HT component, use the Manual activation function for the outputs (all the all or nothing outputs excluding

the compressors) via the "INSTALLATION" menu on the appliances display. Use a voltmeter to check that the regulator output is activated (230V)

and that the component is question in also activated.

² The Aqu@ Scop HT retains a very comprehensive log of alarms, i.e. the 150 last alarms, as well as temperature probe values (water inlet and outlet,

outdoor and outdoor battery) when the alarm appears. You can access this log from the main menu (sub-menu "Alarm log").

Press the ENTER (

) key to switch back and forth between the log screen and the probes screen.

Generally, an alarm means that there is an anomaly with the appliance. We strongly advise against repeatedly resetting an alarm at the risk

of causing irreparable damage to one or several components.

Simple diagnosis advice. In the event of a breakdown, you should contact your local after sales department

for conrmation and assistance.

Compressor does not start

Problem symptoms Probable cause Recommended action

Power is present at the compressor terminal but the motor does not rotate

Motor burnt out Replace the compressor

Motor contactor inoperable Coil burnt out or contacts broken Repair or replace the contactor

No current upstream of the motor contactor

Circuit breaker tripped

Check the fuses / thermo-magnetic circuit breakers and electrical connections

Current upstream of the fuse, but not on the contactor side

Fuse blown or thermo-magnetic circuit breaker tripped

Replace the fuse. Reset the thermo-magnetic circuit breaker Check current values

Low voltage measured on voltmeter

Voltage too low Contact your electricity supplier
