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 (R410A) circulates.

-In the evaporator (ref.

13, figure 7, page 10 ) :

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 -20 °C outdoor temperature).

-In the compressor (ref. 10, fig 7 , page 10 ) :

The vaporised refrigerant brought to high pressure and takes on more calories.

-In the condenser (ref. 15, figure 8, page 10 ) :

The energy in the refrigerant is transmitted to the heating circuit. The refrigerant returns to liquid state.

-In the expansion valve (ref. 9, figure 7, page 10 ) :

The liquefied 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 room temperature based on the outdoor temperature measurement and governed by the temperature control.

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

The hydraulic unit is equipped with an electric back-ups system, which is triggered to provide additional heat during the coldest periods.

• Regulation functions

-The heating circuit’s initial temperature is controlled by the temperature control.

-The power of the outdoor unit is modulated according to initial heating temperature via the “inverter” compressor.

-Possibility to set the setpoint of maximun heating initial temperature.

-Control of the electric back-up heating.

-The daily timer program enables you to define the periods for comfortable or reduced ambient temperature.

-Summer/winter mode switchover is automatic.

-Control of the supplementary boiler* (the electric backups are deactivated).

-The room thermostat* (option) provides a corrective action for the temperature control

-Control of a second heating circuit*.

-Domestic hot water : Heating time programme, control of the operation of the DHW circulation pump*.

-Control of swimming pool heating*.

-Managing the cooling*.

• 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).

The default heat pump program (line 560, 561 and 562) is set for comfort temperature from 0.00 to 5.00h and for reduced temperature for the rest of the day.

This optimises electrical consumption while ensuring comfortable availability of hot water.

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, figure 39, page 29 ).

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.

• Protection functions

-Anti-legionella cycle for domestic hot water.

If the heat pump is equipped with optional equipment and the associated kits.

Split system (3-phase)

2 Installation

2 1 Regulation installation and maintenance conditions

The appliance must be installed and the maintained by an approved professional in accordance with the prevailing regulations and code of practice, in particular:

The legislation on the handling of refrigerants.

2 2 Unpacking and reservations

2 2 1 Receipt

Carefully check, in the carrier’s presence, the general appearance of the appliances and check that the outdoor 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 hours and send a copy of this letter to the After-Sales service.

2 2 2 Handling

The outdoor unit should not be laid on its side or back during transport.

Laying the unit down during transport is likely to damage the internal tubes and the compressor suspensions.

Any damage caused by transportation of the unit lying down is not covered by the warranty.

If necessary the outdoor unit may be tilted only during manual handling (to go through a door or use a staircase).

This operation must be conducted very carefully and the appliance must be immediately restored to upright position.

2 2 3 Containment of refrigerant circuits

All refrigerant circuits fear contamination from dust and moisture. If such pollutants introduced into refrigeration circuit, they can contribute to degrade the reliability of the heat pump.

It’s necessary to ensure correct containment connections and refrigerant circuits (hydraulic unit, outdoor unit).

In case of subsequent failure and expertise, the finding of the presence of moisture or foreign objects into the compressor oil would lead to systematic exclusion of warranty.

-Check upon receipt that the fittings and the refrigeration circuit caps mounted on hydraulic unit and outdoor unit are properly seated and locked (impossible to loosen bare hands). If this’s not the case, tighten them using an against wrench.

-Check also that the refrigerant connections are sealed

(plastic caps or tubes crushed at the ends and soldered).

If the caps must be removed during installation (tubes cut by example), put back them as soon as possible.

2 2 4 Accessories provided

-Accessories provided with the outdoor unit ( figure 10 ).

-Accessories provided with the hydraulic unit

( figure 9 )

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 qualified person.

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

Observe the maximum and minimum distances between the hydraulic unit and the outdoor unit

( figure 17, page 16 ) ; the guarantee of the performances and the system’s service life depend on this.

2 4 Installation of the outdoor unit

2 4 1 Installation precautions

The outdoor 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 ( figure 11 ).

• 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.

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

• The outdoor unit is able to withstand bad weather but avoid installing in a position where it is likely to be exposed to significant dirt or flowing water (under a defective gutter for example).

• Water may drain away from the outdoor 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 the outdoor unit (see figure 12, page 14 ).

• Nothing should obstruct the air circulation through the evaporator and from the fan.

• Keep the outdoor unit away from heat sources and inflammable products.

• Make sure the appliance not disturb the surrounding area or users (noise level, draught generated, low

Split system (3-phase) temperature of the air being blown out, with the risk of freezing plants in its path).

• The surface supporting the outdoor unit should:

- be permeable (soil, gravel, etc),

-support its weight easily,

-provide a solid fixing and

-not transmit any vibration to the dwelling.

(Anti-vibratory blocks are available as an option).

• The wall bracket can not be used in conditions likely to transmit vibrations, ground position is preferred.

2 4 2 Outdoor unit positioning

The outdoor 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 ( figure 12 ).

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

2 4 3 Condensate drain hose

(see figure 12 ).

If the use of a discharge pipe is imperative:

-Use the elbow provided (

C) to connect a 16 mm 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 flow 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

H* ≥ 50mm

* In regions subject to frequent snow,

(H) must be greater than the average snow layer.

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 sufficient space all around the hydraulic unit

( figure 13 ).

• Be careful not to bring inflammable gas near to the heat pump during its installation, in particular when it requires brazing. The appliances are not fireproof and should not therefore be installed in a potentially explosive atmosphere.

-To avoid condensation inside the condenser, remove the refrigerant circuit caps

only when building the

refrigerant connections

-If the refrigerant connection only occurs at the end of the installation, be sure that the refrigerant circuit caps* remain in place and tight throughout the installation duration.

* (hydraulic unit side and outdoor unit side)

-After every intervention on the refrigeration circuit and before final connection, take care to replace the plugs in order to avoid any pollution from the refrigeration circuit (The sealing with tape is prohibited).

2 5 2 Positioning the hydraulic unit

-Remove the front panel (2 screws A, figure 14 )

-Remove the sides (4 screws

B, figure 15 ).

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

-Hook the appliance onto its support.

-Refit the sides. Refit the front panel.

2 6 Refrigeration connections

This appliance uses refrigerant R410A

Comply with the legislation for handling refrigerants.

2 6 1 Rules and precautions

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

• Minimum necessary tools

-Set of manometers (Manifold) with hoses exclusively reserved for HFCs (Hydrofluorocarbons).

-Vacuum gauge whith isolation valves.

-Vacuum pump specially for HFCs (use of a traditional vacuum pump is authorized if, and only if, it is fitted with a non-return valve on the suction side).

-Flaring tool, Pipe-cutter.

-Deburring tool.

-Wrenches.

-Refrigerant gas leak detector certified (sensitivity 5g/year).

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

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, fit without lubrication.

• Brazing on the refrigeration circuit (if necessary)

-Silver brazing (40% minimum recommended).

-Brazing only under dry nitrogen internal flux.

Coat the flared surface with

POE refrigeration oil

Do not use mineral oil

Figure 16 - Prevention of gas leaks

• To eliminate any filings 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.

• Proceed to insulate the gas and liquid pipes to avoid any condensation. Use insulating sleeves resistant to temperatures over 90 °C. In addition if the humidity level in the areas where the refrigeration pipes pass risks exceeding 70%, protect the pipes with insulating sleeves. Use a sleeve thicker than 15mm if the humidity reaches 70~80%, and a sleeve thicker than 20 mm 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 insulating sleeves 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 (fibreglass wool is prohibited).

2 6 2 Refrigeration connections

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

Comply with the pipe diameters and the permitted pipe lengths ( figure 17 ).

The minimum length of the refrigeration connections

is 5 m for correct operation

The appliance will be excluded from guarantee if it is used with refrigeration connections less than 5 m long.

If the refrigeration connections are exposed to weathering or UV- and the insulation is not strong, it is necessary to provide protection.

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

If the distance between the outdoor unit and the hydraulic unit 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

(See para. "Additionnal charge" , page 20 ).

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 flared connections

Connections must be made the day of the filling the installation with gas (see § 2 7, page 19 ).

Take particular care positioning the tube opposite its connector so as not to risk damaging the threads A carefully aligned connector can be fitted 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

-Remove the plugs from the pipes and the refrigeration connections.

-Present the pipe to the flared connector and screw the nut by hand while holding the connector with a wrench until contact.

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 unit.

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

The diameter of the pipes between the hydraulic unit and the heating collector must be at least 1 inch

(26x34mm).

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

Tightening torque : 15 to 35 N.m

Use union connectors to facilitate removing the hydraulic unit.

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 fitting in accordance with prevailing trade practice for plumbing work :

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

-Use Teflon 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 unit 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, paraffin, etc.).

In the case of an old installation, provide a sufficiently 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 filling it definitively.

2 8 3 Filling and purging the installation

Check the pipe fixings, the tightness of the connectors and the stability of the hydraulic unit.

Check the direction in which the water is circulating and 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 the bleeder valve for the hydraulic unit to remove the air contained in the conduits.

Close the drain and bleeder 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 28 ), once the machine has started, purge the hydraulic unit again

(2 liters of water).

2 9 Electrical connections

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 fitting operations have been completed (fixing, assembly, etc.).

Warning

The contract concluded with the energy provider must be sufficient 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 outdoor unit, curve C for the electric heating and domestic water back-ups (see tables on page 23 ).

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

This appliance is designed to operate under a nominal voltage of 400 V, +/- 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.

Unsufficient tightening can cause overheating, leading to breakdown or even a fire.

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, figure 27 ).

Rigid wires are always preferable for fixed 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 firmly onto the loop created.

Flexible wires (B, figure 27 )

H07RNF type (or superior quality) flexible wire can be used with certain precautions :

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

-With tightening pliers, fit a round tag with a diameter corresponding to the terminal screw’s diameter on the end of the wire.

-Tighten the tag firmly onto the terminal with a screwdriver.

-We strongly advise against using flexible wires without round tags.

-Always protect the cables when passing them through cable clamps with PVC protective conduit 0,5 to 1 mm thick.

The heat pump’s operation can be controlled to suit special contracts (e.g. off-peak, day/night).

In particular, domestic hot water (DHW) at Nominal temperature will be produced during the off-peak hours when electricity is cheaper.

-Connect the "Power Provider” contact to input EX5.

-Set the parameter (1620) to "Off-peak hours".

• 230V on input EX5 = "Peak hours" information activated

(Basic setting / Modification possible line 5989, menu Configuration).

• Power limitation or EJP (peak day removal) :

Power limitation is intended to reduce electrical consumption when this is too high compared to the contract with the power provider.

-Connect the power limiting device to input EX4, the back-ups for the heat pump and the DHW stop in the event of over-consumption by the dwelling.

• 230 V on input EX4 = power limitation in progress.

(Basic setting / Modification possible line 5987, menu Configuration). (Operating line 2920)

• 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 floor, Connect the floor heating safety device into the connector of the floor 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 fitting 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 2,5 m from the floor.

It is essential that it avoid any sources of heat such as flues, 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 outdoor air temperature.

-Connect the outdoor sensor to the M and B9 terminals on the heat pump control board.

2 11 Room thermostat and/or room control unit

The room thermostat (room control unit) is optional.

Consult the fitting instructions on the sensor’s packaging.

The sensor must be installed in the living room area on a very uncluttered wall. It must be installed so as to be easily accessible.

Avoid direct sources of heat (chimney/flue, 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.

• Installation equipped with two room thermostats.

-Connect each of the sensors to one of the CL+ or CL- terminals on the heat pump control board using the connector supplied.

• Installation equipped with a room thermostat and a room control unit.

-Connect the sensor to one of the CL+ or CL- terminals on the heat pump control board.

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

Installation and operating manual "1364 - EN" - 29 -

Split system (3-phase)

2 12 Start-up

-Make sure that ALL DIP SW are OFF before starting up. DIP SW shuold be set OFF for normal operation.

Power supply to the hydraulic unit must be turned off while toching DIP SW.

-Close the installation’s main circuit breaker.

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

-Engage the start/stop switch.

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 outdoor 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 unit will re-establish itself in a few moments.

During the regulator initialisation phase, the display shows all the symbols and then "Data, update" and then

"State heat pump".

-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 32 ).

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

The regulating system uses an average initial outdoor 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 Configuring the room thermostat

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

-Hold down the presence key for more than 3 seconds.

The room thermostat displays RU and a number flashes.

-Turn the wheel to choose the zone (1, 2).

If the installation is fitted with 2 room thermostats,

- First connect one room thermostat and configure it in zone 2

- Then connect the other room thermostat and configure it as default in zone 1.

-Hold down the presence key ; the room thermostat displays P1 and a flashing number.

1 : Automatic recording : a correction of the setting with the button is adopted without any particular confirmation (timeout) or by pressing the regime key.

2 : Recording with confirmation : a correction of the setting with the button is not adopted until the regime key is pressed.

-Press the presence key again ; the room thermostat displays P2 and a flashing number.

0 : OFF : all the operating elements are engaged.

1 : ON : the following operating elements are locked :

Switching over the heating circuit’s operating mode.

Adjusting the comfort setting.

Changing the operating level.

The room thermostat displays OFF for 3 seconds when a locked button is pressed.

2 14 Configuring room control unit

During commissioning, after an initialisation period of approx. 3 minutes, the user’s language must be set :

-Press the key

-Choose menu "User interface".

-Choose language.

-Select the language ( english, français, nederlands, español, etc).

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 outdoor 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 ( figure 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 outdoor temperature on the initial heating temperature variations.

The higher the slope, the more a slight reduction in the outdoor temperature causes a significant 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 ( figure 42 ).

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

- 32 -

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 first 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 influence 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 influence 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.
