▪ Make sure the area is well ventilated. Do NOT block any

ventilation openings.

▪ Make sure the unit is level.

▪ Make sure walls sensitive to heat (e.g. wood) are protected by

suitable insulation.

▪ ONLY operate the gas boiler if a sufficient supply of combustion

air is ensured. In case of a concentric air/flue gas system dimensioned according to the specifications of this manual, this is fulfilled automatically and there are no other conditions for the equipment installation room. This method of operation applies exclusively.

▪ This gas boiler is NOT designed for room air dependent operation.

Do NOT install the unit in the following places:

▪ In potentially explosive atmospheres.

▪ In places where there is machinery that emits electromagnetic

waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.

▪ In places where there is a risk of fire due to the leakage of

flammable gases (example: thinner or gasoline), carbon fibre, ignitable dust.

▪ In places where corrosive gas (example: sulphurous acid gas) is

produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.

▪ In bathrooms.

▪ In places where frost is possible. The ambient temperature around

the indoor unit should be >5°C.

Total weight: 66kg

1.2.3 Refrigerant

If applicable. See the installation manual or installer reference guide of your application for more information.

WARNING

Take sufficient precautions in case of refrigerant leakage. If refrigerant gas leaks, ventilate the area immediately. Possible risks:

▪ Excessive refrigerant concentrations in a closed room

can lead to oxygen deficiency.

▪ Toxic gas may be produced if refrigerant gas comes

into contact with fire.

WARNING

Always recover the refrigerant. Do NOT release them directly into the environment. Use a vacuum pump to evacuate the installation.

NOTICE

After all the piping has been connected, make sure there is no gas leak. Use nitrogen to perform a gas leak detection.

NOTICE

▪ To avoid compressor breakdown, do NOT charge more

than the specified amount of refrigerant.

▪ When the refrigerant system is to be opened,

refrigerant must be treated according to the applicable legislation.

WARNING

Make sure there is no oxygen in the system. Refrigerant may only be charged after performing the leak test and the vacuum drying.

▪ In case re-charge is required, refer to the nameplate of the unit. It

states the type of refrigerant and necessary amount.

▪ The unit is factory charged with refrigerant and depending on pipe

sizes and pipe lengths some systems require additional charging of refrigerant.

▪ Only use tools exclusively for the refrigerant type used in the

system, this to ensure pressure resistance and prevent foreign materials from entering into the system.

▪ Charge the liquid refrigerant as follows:

If Then

A siphon tube is present

(i.e., the cylinder is marked with "Liquid filling siphon attached")

Charge with the cylinder upright.

NOTICE

Make sure refrigerant piping installation complies with applicable legislation. In Europe, EN378 is the applicable standard.

NOTICE

Make sure the field piping and connections are not subjected to stress.

WARNING

During tests, NEVER pressurize the product with a pressure higher than the maximum allowable pressure (as indicated on the nameplate of the unit).

A siphon tube is NOT present Charge with the cylinder upside

down.

▪ Open refrigerant cylinders slowly.

▪ Charge the refrigerant in liquid form. Adding it in gas form may

prevent normal operation.

CAUTION

When the refrigerant charging procedure is done or when pausing, close the valve of the refrigerant tank immediately. If the valve is not closed immediately, remaining pressure might charge additional refrigerant. Possible consequence: Incorrect refrigerant amount.

1 General safety precautions

1.2.4 Water

If applicable. See the installation manual or installer reference guide of your application for more information.

NOTICE

Make sure water quality complies with EU directive 98/83EC.

Avoid damages caused by deposits and corrosion. To prevent corrosion products and deposits, observe the applicable regulations of technology.

Measures for desalination, softening or hardness stabilization are necessary if the filling and top-up water have a high total hardness (>3 mmol/l–sum of the calcium and magnesium concentrations, calculated as calcium carbonate).

Using filling water and top-up water which does NOT meet the stated quality requirements can cause a considerably reduced service life of the equipment. The responsibility for this is entirely that of the user.

1.2.5 Electrical

DANGER: RISK OF ELECTROCUTION

▪ Turn OFF all power supply before removing the

switch box cover, connecting electrical wiring or touching electrical parts.

▪ Disconnect the power supply for more than 1minute,

and measure the voltage at the terminals of main circuit capacitors or electrical components before servicing. The voltage MUST be less than 50 V DC before you can touch electrical components. For the location of the terminals, see the wiring diagram.

▪ Do NOT touch electrical components with wet hands.

▪ Do NOT leave the unit unattended when the service

cover is removed.

WARNING

If NOT factory installed, a main switch or other means for disconnection, having a contact separation in all poles providing full disconnection under overvoltage category III condition, shall be installed in the fixed wiring.

WARNING

▪ ONLY use copper wires.

▪ Make sure the field wiring complies with the applicable

legislation.

▪ All field wiring must be performed in accordance with

the wiring diagram supplied with the product.

▪ NEVER squeeze bundled cables and make sure they

do not come in contact with the piping and sharp edges. Make sure no external pressure is applied to the terminal connections.

▪ Make sure to install earth wiring. Do NOT earth the unit

to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.

▪ Make sure to use a dedicated power circuit. NEVER

use a power supply shared by another appliance.

▪ Make sure to install the required fuses or circuit

breakers.

▪ Make sure to install an earth leakage protector. Failure

to do so may cause electric shock or fire.

▪ When installing the earth leakage protector, make sure

it is compatible with the inverter (resistant to high frequency electric noise) to avoid unnecessary opening of the earth leakage protector.

NOTICE

Precautions when laying power wiring:

▪ Do not connect wiring of different thicknesses to the

power terminal block (slack in the power wiring may cause abnormal heat).

▪ When connecting wiring which is the same thickness,

do as shown in the figure below.

▪ For wiring, use the designated power wire and connect

firmly, then secure to prevent outside pressure being exerted on the terminal board.

▪ Use an appropriate screwdriver for tightening the

terminal screws. A screwdriver with a small head will damage the head and make proper tightening impossible.

▪ Over-tightening the terminal screws may break them.

Install power cables at least 1 metre away from televisions or radios to prevent interference. Depending on the radio waves, a distance of 1metre may not be sufficient.

WARNING

▪ After finishing the electrical work, confirm that each

electrical component and terminal inside the electrical components box is connected securely.

▪ Make sure all covers are closed before starting up the

unit.

NOTICE

Only applicable if the power supply is three‑phase, and the compressor has an ON/OFF starting method.

If there exists the possibility of reversed phase after a momentary black out and the power goes on and off while the product is operating, attach a reversed phase protection circuit locally. Running the product in reversed phase can break the compressor and other parts.

1.2.6 Gas

The gas boiler is factory‑set to:

▪ the type of gas quoted on the type identification plate or on the

setting type identification plate,

▪ the gas pressure quoted on the type identification plate.

Operate the unit ONLY with the gas type and gas pressure indicated on these type identification plates.

Installation and adaptation of the gas system MUST be conducted by:

▪ personnel qualified for this work,

▪ in compliance with valid gas installation related guidelines,

▪ in accordance with applicable regulations of the gas supply

company,

▪ In accordance with local and national regulations.

Do NOT install the unit in places such as:

▪ In places where a mineral oil mist, spray or vapour may be

present in the atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.

▪ Sound sensitive areas (e.g. near a bedroom and the like), so that

the operation noise will cause no trouble.

▪ The foundation must be strong enough to bear the weight of the

unit. Take the weight of the unit with a domestic hot water tank full of water into account. Make sure, in the event of a water leak, water cannot cause any damage to the installation space and surroundings.

▪ In places with high humidity (max. RH=85%), for example a

bathroom.

▪ In places where frost is possible. Ambient temperature around the

indoor unit should be >5°C.

▪ The indoor unit is designed for indoor installation only and for

ambient temperatures ranging 5~35°C in cooling mode and 5~30°C in heating mode.

6.3 Preparing refrigerant piping

6.3.1 Refrigerant piping requirements

INFORMATION

Also read the precautions and requirements in the "General safety precautions" chapter.

▪ Piping material: Phosphoric acid deoxidised seamless copper.

▪ Piping diameter:

Liquid piping Ø6.4mm (1/4")

If the temperature is higher than 30°C and the humidity is higher than RH 80%, the thickness of the insulation materials should be at least 20 mm to prevent condensation on the surface of the insulation.

6.4 Preparing water piping

6.4.1 Water circuit requirements

INFORMATION

Also read the precautions and requirements in the "General safety precautions" chapter.

▪ Connecting piping – Legislation. Make all piping connections in

accordance with the applicable legislation and the instructions in the "Installation" chapter, respecting the water inlet and outlet.

▪ Connecting piping – Force. Do NOT use excessive force when

connecting the piping. Deformation of the piping can cause malfunctioning of the unit.

▪ Connecting piping – Tools. Only use appropriate tooling to

handle brass, which is a soft material. If NOT, pipes will get damaged.

▪ Connecting piping – Air, moisture, dust. If air, moisture or dust

gets into the circuit, problems may occur. To prevent this:

▪ Only use clean pipes

▪ Hold the pipe end downwards when removing burrs.

▪ Cover the pipe end when inserting it through a wall, to prevent

dust and/or particles entering the pipe.

▪ Use a decent thread sealant to seal connections.

▪ Closed circuit. Use the indoor unit ONLY in a closed water

system. Using the system in an open water system will lead to excessive corrosion.

▪ Glycol. For safety reasons, it is NOT allowed to add any kind of

glycol to the water circuit.

▪ Piping length. It is recommended to avoid long runs of piping

between the domestic hot water tank and the hot water end point (shower, bath,…) and to avoid dead ends.

▪ Piping diameter. Select the water piping diameter in relation to

the required water flow and the available external static pressure of the pump. See "15 Technical data"on page96 for the external static pressure curves of the indoor unit.

▪ Water flow. You can find the minimum required water flow for

indoor unit operation in the following table. In all cases, this flow needs to be guaranteed. When the flow is lower, the indoor unit will stop operation and display error 7H.

Minimum required flow rate

05 models 7l/min

08 models 8l/min

▪ Field supply components – Water. Only use materials that are

compatible with water used in the system and with the materials used in the indoor unit.

▪ Field supply components – Water pressure and temperature.

Check that all components in the field piping can withstand the water pressure and water temperature.

▪ Water pressure. The maximum water pressure is 3bar. Provide

adequate safeguards in the water circuit to ensure that the maximum pressure is NOT exceeded.

▪ Water temperature – Heat pump convectors. In case heat

pump convectors are connected, the temperature of the water in the convectors should NOT exceed 65°C. If necessary, install a thermostatic controlled valve.

▪ Water temperature – Underfloor heating loops. In case

underfloor heating loops are connected, install a mixing station to prevent water that is too hot from entering the underfloor heating circuit.

▪ Water temperature. All installed piping and piping accessories

(valve, connections,…) MUST withstand the following temperatures:

RAD1…3 Radiator (field supply)

▪ Drainage – Low points. Provide drain taps at all low points of the

system in order to allow complete drainage of the water circuit.

▪ Drainage – Pressure relief valve. Provide a proper drain for the

pressure relief valve to avoid water coming into contact with electrical parts.

▪ Air vents. Provide air vents at all high points of the system, which

must also be easily accessible for servicing. An automatic air purge is provided in the indoor unit. Check that the air purge is NOT tightened too much, so that automatic release of air in the water circuit is possible.

▪ Zn-coated parts. Never use Zn-coated parts in the water circuit.

Because the unit's internal water circuit uses copper piping, excessive corrosion may occur.

▪ Non-brass metallic piping. When using non-brass metallic

piping, insulate the brass and non-brass properly so that they do NOT make contact with each other. This to prevent galvanic corrosion.

▪ Valve – Separating circuits. When using a 3-way valve in the

water circuit make sure that the domestic hot water circuit and the floor heating circuit is fully separated.

▪ Valve – Change‑over time. When using a 2-way valve or a 3-way

valve in the water circuit, the maximum change-over time of the valve must be 60seconds.

▪ Filter. It is strongly recommended to install an additional filter on

the heating water circuit. Especially to remove metallic particles from foul heating piping, it is recommended to use a magnetic or cyclone filter, which can remove small particles. Small particles may damage the unit and will NOT be removed by the standard filter of the heat pump system.

▪ Dirt separator – Old heating installations. In case of old heating

installations, it is recommended to use a dirt separator. Dirt or sediment from the heating installation can damage the unit and reduce its lifetime. The domestic hot water circuit can also be protected by a filter to prevent failure during domestic hot water operation.

▪ Domestic hot water tank – Capacity. To avoid stagnation of

water, it is important that the storage capacity of the domestic hot water tank meets the daily consumption of domestic hot water.

▪ Domestic hot water tank – After installation. Immediately after

installation, the domestic hot water tank must be flushed with fresh water. This procedure must be repeated at least once a day the first 5 consecutive days after installation.

▪ Domestic hot water tank – Standstills. In cases where during

longer periods of time there is no consumption of hot water, the equipment MUST be flushed with fresh water before usage.

▪ Domestic hot water tank – Disinfection. For the disinfection

function of the domestic hot water tank, see "Domestic hot water

control: advanced"on page66.

Maximum water volume

Use the following graph to determine the maximum water volume for the calculated pre-pressure.

6.4.2 Formula to calculate the expansion vessel

The pre-pressure (Pg) of the vessel depends on the installation height difference (H):

Pg=0.3+(H/10) (bar)

6.4.3 To check the water volume and flow rate

The indoor unit has an expansion vessel of 10litre with a factory set pre-pressure of 1bar.

To make sure that the unit operates properly:

▪ You must check the minimum and maximum water volume.

▪ You might need to adjust the pre-pressure of the expansion

vessel.

Minimum water volume

Check that the total water volume in the installation is minimum

13.5litre, the internal water volume of the indoor unit NOT included.

Minimum flow rate

Check that the minimum flow rate (required during defrost/backup heater operation) in the installation is guaranteed in all conditions.

NOTICE

When circulation in each or certain space heating loops is controlled by remotely controlled valves, it is important that the minimum flow rate is guaranteed, even if all valves are closed. In case the minimum flow rate cannot be reached, a flow error 7H will be generated (no heating/operation).

▪ Inappropriate setting of the expansion vessel pre-pressure will

lead to malfunction of the system.

Changing the pre-pressure of the expansion vessel should be done by releasing or increasing nitrogen pressure through the schräder valve of the expansion vessel.

a Schräder valve

6.4.5 To check the water volume: Examples

Example 1

The indoor unit is installed 5 m below the highest point in the water circuit. The total water volume in the water circuit is 100l.

No actions or adjustments are required for either underfloor heating loops or radiators.

Example 2

The indoor unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 350 l. Radiators are installed, so use the graph of 80°C.

Actions:

▪ Because the total water volume (350 l) is more than the default

water volume (140l), the pre-pressure must be decreased.

▪ The required pre-pressure is:

Pg = (0.3+(H/10))bar = (0.3+(0/10))bar=0.3bar.

▪ The corresponding maximum water volume at 0.3 bar is 205 l.

(See the graph in the chapter above).

▪ Because 350 l is more than 205l, the expansion vessel is too

small for the installation. Therefore install an extra vessel outside the installation.

6.5.2 About preferential kWh rate power supply

Electricity companies throughout the world work hard to provide reliable electric service at competitive prices and are often authorized to bill clients at benefit rates. E.g. time-of-use rates, seasonal rates, Wärmepumpentarif in Germany and Austria, ...

This equipment allows for connection to such preferential kWh rate power supply delivery systems.

Consult with the electricity company acting as provider at the site where this equipment is to be installed to know whether it is appropriate to connect the equipment in one of the preferential kWh rate power supply delivery systems available.

When the equipment is connected to such preferential kWh rate power supply, the electricity company is allowed to:

▪ interrupt power supply to the equipment for certain periods of time;

▪ demand that the equipment only consumes a limited amount of

electricity during certain periods of time.

The indoor unit is designed to receive an input signal by which the unit switches into forced off mode. At that moment, the gas boiler can still operate to provide heating, but the outdoor unit compressor will NOT operate.

Whether the power supply is interrupted or not, the wiring to the unit is different.

PCB in the event of power supply interruption of the preferential kWh rate power supply)

The following applies ONLY for the French market: "Bleu Ciel tarif"

In France there is a preferential kWh rate called "Bleu Ciel tarif". This rate divides the days of the year in:

▪ blue days (preferential electricity rate, ideal for heat pump

operation),

▪ white days (ideal for heat pump and hybrid operation),

▪ and red days (high electricity rate, boiler operation preferred).

It is recommended to use the preferential kWh rate power supply contact (4) to force boiler operation during red days. Note that sometimes it is required to set the meter on such that, it only closes the contact on red days. Please refer to the manual of the applicable meter.

The indoor unit and gas boiler are NOT compatible with other combinations of contacts (e.g., closed contacts on white/blue days). Connect the indoor unit and gas boiler as follows: see illustration in column "Power supply is NOT interrupted" in the table above.

7.6 Condensate pipe work

INFORMATION

The condensate discharge system MUST be made of plastic, no other materials may be used. The discharge duct MUST have a minimum gradient of 5~20 mm/m. Condensate discharge via the gutter is NOT allowed due to risk of frost and the possible damage to the materials.

7.6.1 Internal connections

If possible, the condensate drain pipe should be routed and terminated so that the condensate drains away from the boiler under gravity to a suitable internal foul water discharge point such as an internal soil and vent stack. A suitable permanent connection to the foul waste pipe should be used.

a Condensate discharge from boiler b Soil and vent stack c Minimum 450mm and up to 3 storeys

If the first option is NOT possible, an internal kitchen or bathroom waste pipe, washing machine pipe can be used. Make sure that the condensate drain pipe is connected downstream of the waste trap.

7.6.2 External connections

If an externally condensate drainage pipe is used, following measures should be made to prevent freezing:

▪ The pipe should be run internally as far as possible before going

to the outside. The pipe diameter should be increased to a minimum inner diameter of 30 mm (typically outer diameter of 32mm) before it goes through the wall.

▪ The external run should be kept as short as possible, taking the

most vertical route possible to the discharge point. Take into account that there are no horizontal section in which condensate might collect.

▪ The external pipe should be insulated. Use a suitable waterproof

and weather proof insulation ("ClassO" pipe insulation is suitable for this purpose).

▪ The use of fittings and elbows should be kept to a minimum. Any

internal burrs should be removed so that the internal pipe section is as smooth as possible.

7.7.6 To braze the pipe end

The indoor unit and outdoor unit have flare connections. Connect both ends without brazing. If brazing should be needed, take the following into account:

▪ When brazing, blow through with nitrogen to prevent creation of

large quantities of oxidised film on the inside of the piping. This film adversely affects valves and compressors in the refrigerating system and prevents proper operation.

▪ Set the nitrogen pressure to 20kPa (just enough so it can be felt

on the skin) with a pressure-reducing valve.

f Nitrogen

▪ Do NOT use anti-oxidants when brazing pipe joints.

Residue can clog pipes and break equipment.

▪ Do NOT use flux when brazing copper-to-copper refrigerant

piping. Use phosphor copper brazing filler alloy (BCuP), which does not require flux. Flux has an extremely harmful influence on refrigerant piping systems. For instance, if chlorine based flux is used, it will cause pipe corrosion or, in particular, if the flux contains fluorine, it will deteriorate the refrigerant oil.

7.7.7 Using the stop valve and service port

To handle the stop valve

Take the following guidelines into account:

▪ The stop valves are factory closed.

▪ The following illustration shows each part required in handling the

valve.

a Spanner b Torque wrench

▪ When it is expected that the operating pressure will be low (e.g.

when cooling will be performed while the outside air temperature is low), sufficiently seal the flare nut in the stop valve on the gas line with silicon sealant to prevent freezing.

Silicon sealant, make sure there is no gap.

To open/close the stop valve

1 Remove the valve cover.

2 Insert a hexagon wrench (liquid side: 4mm, gas side: 6mm)

into the valve stem and turn the valve stem:

Counterclockwise to open. Clockwise to close.

3 When the valve stem cannot be turned any further, stop turning.

The valve is now opened/closed.

To handle the stem cap

Take the following guidelines into account:

▪ The stem cap is sealed where indicated with the arrow. Do NOT

damage it.

▪ After handling the stop valve, make sure to tighten the stem cap

securely.

▪ For the tightening torque, refer to the following table.

▪ Check for refrigerant leaks after tightening the stem cap.

a Service port and service port cap b Valve stem c Field piping connection d Stem cap

▪ Keep both stop valves open during operation.

▪ Do NOT apply excessive force to the valve stem. Doing so may

break the valve body.

▪ Always make sure to secure the stop valve with a spanner, then

loosen or tighten the flare nut with a torque wrench. Do NOT place the spanner on the stem cap, as this could cause a refrigerant leak.

7.8 Checking the refrigerant piping

7.8.1 About checking the refrigerant piping

The outdoor unit's internal refrigerant piping has been factory tested for leaks. You only have to check the outdoor unit's external refrigerant piping.

Before checking the refrigerant piping

Make sure the refrigerant piping is connected between the outdoor unit and the indoor unit.

Typical workflow

Checking the refrigerant piping typically consists of the following stages:

1 Checking for leaks in the refrigerant piping.

2 Performing vacuum drying to remove all moisture, air or

nitrogen from the refrigerant piping.

If there is a possibility of moisture being present in the refrigerant piping (for example, water may have entered the piping), first carry out the vacuum drying procedure below until all moisture has been removed.

7.8.2 Precautions when checking the refrigerant piping

NOTICE

To avoid damage to the surroundings in case of water leakage, it is recommended to close the cold water inlet shut‑off valves during periods of absence.

3 In case of connection with the optional domestic hot water tank,

see the installation manual of the domestic hot water tank.

NOTICE

▪ A drain device and pressure relief device should be

installed on the cold water inlet connection of the domestic hot water cylinder.

▪ To avoid back siphonage, it is recommended to install a

non-return valve on the water inlet of the domestic hot water tank in accordance with the applicable legislation.

▪ It is recommended to install a pressure reducing valve

on the cold water inlet in accordance with the applicable legislation.

▪ An expansion vessel should be installed on the cold

water inlet in accordance with the applicable legislation.

▪ It is recommended to install the pressure relief valve on

a higher position than the top of the domestic hot water tank. Heating of the domestic hot water tank causes water to expand and without pressure relief valve the water pressure inside the tank can rise above the tank design pressure. Also the field installation (piping, tapping points, etc.) connected to the tank is subjected to this high pressure. To prevent this, a pressure relieve valve needs to be installed. The overpressure prevention depends on the correct operation of the field installed pressure relief valve. If this is NOT working correctly, overpressure will deform the tank and water leakage may occur. To confirm good operation, regular maintenance is required.

7.10.4 Connecting the water piping of the gas boiler

To connect the water piping for space heating

7.13.3 Calculate the total piping length

When the resistance of the flue pipe and air supply pipe increase, the appliance power will decrease. The maximum permitted reduction in power is 5%.

The resistance of the air supply pipe and combustion gas flue depends on:

▪ the length,

▪ the diameter,

▪ all components (bends, elbows,…).

The total permitted pipe length of the air supply and the combustion gas flue is indicated for each appliance category. For dual pipe connection, the indication of pipe length is based on Ø80mm.

Length (m)

Bend 90° 1.5

Bend 45° 0.45

For a dual pipe connection, all defined lengths assume a diameter of 80mm. In case of smaller or larger pipe diameters, the permissible pipe length is respectively smaller or larger. In case of smaller diameter, the following applies:

▪ Ø70: 0.59×the permissible pipe length for Ø80

▪ Ø60: 0.32×the permissible pipe length for Ø80

▪ Ø50: 0.15×the permissible pipe length for Ø80

7.13.10 Plume management kit

See the local and national regulations.

Especially for UK:

The plume management kit comprises of a 710 mm horizontal section elbow to connect the 500 mm vertical condensing tube, which has a horizontal or vertical terminal dependant on your requirements. The maximum length of the horizontal flue including the terminal but excluding the initial elbow from the boiler and 500mm vertical condensing tube is 7m.

NOTICE

For each additional 90° elbow used the maximum flue length MUST be reduced by 1.5m whilst the use of 2× 45° bends warrants a reduction of 2m.

The horizontal part of the flue MUST be installed under a 3° fall towards the boiler (5 mm per m) and MUST be supported with a minimum of 1 bracket at each 1 m length. Best recommended position of the bracket is just before the joint.

CAUTION

▪ Sealing rings should ONLY be moisturized with water

before use. Do NOT use soap or other detergents.

▪ When installing flues in voids, make sure that they are

connected and fixed correctly. If in an existing situation a visual inspection is NOT possible, the boiler must NOT be commissioned and remain disconnected from the gas supply until suitable access has been realised.

▪ Make sure to follow the manufacturer’s instructions

regarding maximum length of the flue system, the appropriate flue material, correct jointing methods and the maximum distance between flue support.

▪ Make sure that all joints and seams are gastight and

watertight.

▪ Make sure that the flue system has a uniform gradient

back to the boiler.

7 Installation

7.13.11 Flues in voids

Especially for UK:

The flue system must be connected in accordance with the manufacturers instructions before firing the boiler.

The term void includes ceiling voids, floor voids, purpose built enclosures, service risers, roof spaces or any other enclosure that will restrict access to inspect the flue.

To allow visual inspection, without reliance on devices such as endoscopes, cameras and mirrors, inspection hatches must be provided along the entire length of the flue.

Hatches must be a minimum of 300mm×300 mm and positioned with the edge of the inspection hatch to 1.5 m of any joint and at changes of direction. Bends should be viewable from both directions where the inspection hatch cannot be positioned at the bend.

Where suitable access is not provided the appliance must NOT be commissioned and must be disconnected from the gas supply.

Additionally the entire flue and all flue seals must be installed in accordance with the requirements of BS5440:

▪ Check if the condensate trap is filled with water and correctly

connected to the boiler.

▪ All flue joints are correctly made, unstressed and adequately

supported.

▪ All parts of the flue can be visually inspected. Ensure suitable

access where flue is positioned within voids.

Space heating/cooling control

The basic required settings in order to configure the space heating/ cooling of your system are described in this chapter. The weatherdependent installer settings define the parameters for the weatherdependent operation of the unit. When weather-dependent operation is active, the water temperature is determined automatically depending on the outdoor temperature. Low outdoor temperatures will result in warmer water and vice versa. During weatherdependent operation, the user has the possibility to shift up or down the target water temperature by a maximum of 10°C.

See the user reference guide and/or operation manual for more details about this function.

Leaving water temperature: Modulation

Modulation lowers or raises the desired leaving water temperature in function of the desired room temperature and the difference between this temperature and the actual room temperature. This results in:

▪ stable room temperatures exactly matching the desired

temperature (high comfort level),

▪ less On/OFF cycles (low noise level, high comfort and efficiency

levels)

▪ as low as possible leaving water temperatures (high efficiency).

This function is only applicable in case of room thermostat control and is used to calculate the leaving water temperature. After activation, the leaving water temperature can only be read on the user interface, but not changed. Turn OFF modulation to change it. The leaving water temperature can either be a fixed setpoint, or an offset in case of weather-dependent setpoint.

INFORMATION

When leaving water temperature modulation is enabled, the weather‑dependent curve needs to be set to a higher position than [8-06] plus the minimum leaving water temperature setpoint required to reach a stable condition on the comfort setpoint for the room. To increase efficiency, modulation can lower the leaving water setpoint. By setting the weather‑dependent curve to a higher position, it cannot drop below the minimum setpoint.

You can define preset leaving water temperatures:

▪ economic (denotes the desired leaving water temperature which

results in the lowest energy consumption)

▪ comfort (denotes the desired leaving water temperature which

results in the highest energy consumption).

Preset values make it easy to use the same value in the schedule or to adjust the desired leaving water temperature according to the room temperature (see modulation). If you later want to change the value, you ONLY have to do it in one place. Depending on whether the desired leaving water temperature is weather dependent or NOT, the desired shift values or the absolute desired leaving water temperature should be specified.

NOTICE

The preset leaving water temperatures are ONLY applicable for the main zone, as the schedule for the additional zone consists of On/OFF actions.

Temperature ranges (leaving water temperatures)

The purpose of this setting is to prevent selecting a wrong (i.e. too hot or too cold) leaving water temperature. Therefore the available desired heating temperature range and desired cooling temperature range can be configured.

NOTICE

In case of a floor heating application it is important to limit the:

▪ maximum leaving water temperature at heating

operation according to the specifications of the floor heating installation.

▪ the minimum leaving water temperature at cooling

operation to 18~20°C to prevent condensation on the floor.

NOTICE

▪ When adjusting the leaving water temperature ranges,

all desired leaving water temperatures are also adjusted to guarantee they are between the limits.

▪ Always balance between the desired leaving water

temperature with the desired room temperature and/or the capacity (according to the design and selection of the heat emitters). The desired leaving water temperature is the result of several settings (preset values, shift values, weather dependent curves, modulation). As a result, too high or too low leaving water temperatures could occur which lead to overtemperatures or capacity shortage. By limiting the leaving water temperature range to adequate values (depending on the heat emitter), such situations can be avoided.

Example: Set the minimum leaving water temperature to 28°C to avoid NOT to be able to heat up the room: leaving water temperatures MUST be sufficiently higher than the room temperatures (in heating).

Leaving water temperature compensation around 0°C

In heating operation, the desired leaving water temperature is locally increased around an outdoor temperature of 0°C. This compensation can be selected when using an absolute or a weather dependent desired temperature (see illustration below). Use this setting to compensate for possible heat losses of the building due to the evaporation of melted ice or snow (e.g. in cold region countries).

ONLY applicable in room thermostat control and when modulation is enabled. The maximum modulation (=variance) on the desired leaving water temperature decided on the difference between the actual and desired room temperature, e.g. 3°C modulation means the desired leaving water temperature can be increased or lowered by 3°C. Increasing the modulation results in better performance (less On/OFF, faster heat up), but note that depending on the heat emitter, there MUST ALWAYS be a balance (refer to the design and selection of the heat emitters) between the desired leaving water temperature and the desired room temperature.

# Code Description

[A.3.3.2] [F-01] 10°C~35°C (default: 20°C)

The same setting is also used in automatic heating/cooling changeover.

Automatic heating/cooling changeover

The end-user sets the desired operation mode on the user interface: Heating, Cooling or Automatic (see also operation manual/user reference guide). When Automatic is selected, the changing of the operation mode is based on:

▪ Monthly allowance for heating and/or cooling: the end-user

indicates on a monthly base which operation is allowed ([7.5]: both heating/cooling or heating ONLY or cooling ONLY). If the allowed operation mode changes to cooling ONLY, the operation mode changes to cooling. If the allowed operation mode changes to heating ONLY, the operation mode changes to heating.

▪ Averaged outdoor temperature: the operation mode will be

changed in order to ALWAYS be within range determined by the space heating OFF temperature for heating and the space cooling On temperature for cooling. If the outdoor temperature drops, the operation mode switches to heating and vice versa. Note that the outdoor temperature will be time-averaged (see

"8Configuration"on page50).

When the outdoor temperature is between the space cooling On and the space heating OFF temperature, the operation mode remains unchanged unless the system is configured in room thermostat control with one leaving water temperature zone and quick heat emitters. In that case, the operation mode will change based on:

▪ Measured indoor temperature: besides the heating and the

cooling desired room temperature, the installer sets a hysteresis value (e.g. when in heating, this value is related to the desired cooling temperature) and an offset value (e.g. when in heating, this value is related to the desired heating temperature). Example: the desired room temperature in heating is 22°C and in cooling 24°C, with a hysteresis value of 1°C and an offset of 4°C. Changeover from heating to cooling will occur when the room temperature raises above the maximum of the desired cooling temperature added by the hysteresis value (thus 25°C) and the desired heating temperature added by the offset value (thus 26°C). Oppositely, changeover from cooling to heating will occur when the room temperature drops below the minimum of the desired heating temperature subtracted by the hysteresis value (thus 21°C) and the desired cooling temperature subtracted by the offset value (thus 20°C).

▪ Guard timer to prevent too frequent changing from heating to

cooling and vice versa.

When programming the schedule, you can make use of the tank temperatures set as preset values. The tank will then heat up until these setpoint temperatures have been reached. Additionally, a storage stop can be programmed. This feature puts a stop to tank heating even if the setpoint has NOT been reached. Only program a storage stop when tank heating is absolutely undesirable.

The storage economic temperature denotes the lower desired tank temperature. It is the desired temperature when a storage economic action is scheduled (preferably during day).

Weather dependent

The weather dependent installer settings define the parameters for the weather dependent operation of the unit. When weather dependent operation is active the desired tank temperature is determined automatically depending on the averaged outdoor temperature: low outdoor temperatures will result in higher desired tank temperatures as the cold water tap is colder and vice versa. In case of scheduled or scheduled+reheat domestic hot water preparation, the storage comfort temperature is weather dependent (according to the weather dependent curve), the storage economic and reheat temperature are NOT weather dependent. In case of reheat only domestic hot water preparation, the desired tank temperature is weather dependent (according to the weather dependent curve). During weather dependent operation, the enduser cannot adjust the desired tank temperature on the user interface.

WARNING

Be aware that the domestic hot water temperature at the hot water tap will be equal to the value selected in field setting [2-03] after a disinfection operation.

When the high domestic hot water temperature can be a potential risk for human injuries, a mixing valve (field supply) shall be installed at the hot water outlet connection of the domestic hot water tank. This mixing valve shall secure that the hot water temperature at the hot water tap never rise above a set maximum value. This maximum allowable hot water temperature shall be selected according to the applicable legislation.

CAUTION

Be sure that the disinfection function start time [A.4.4.3] with defined duration [A.4.4.5] is NOT interrupted by possible domestic hot water demand.

INFORMATION

In case of error code AH and no interruption of the disinfection function occurred due to domestic hot water tapping, following actions are recommended:

▪ When the Domestic hot water > Type > Reheat or

Reheat + sched. is selected, it is recommended to program the start-up of the disinfection function at least 4 hours later than the last expected large hot water tapping. This start-up can be set by installer settings (disinfection function).

▪ When the Domestic hot water > Type > Scheduled only

is selected, it is recommended to program a Storage eco 3 hours before the scheduled start-up of the disinfection function to preheat the tank.

INFORMATION

Disinfection function is restarted in case the domestic hot water temperature drops 5°C below the disinfection target temperature within the duration time.

INFORMATION

An AH error occurs if you do the following during disinfection:

▪ Set the user permission level to Installer.

▪ Go to the DHWtank temperature home page (Tank).

▪ Press to interrupt the disinfection.

Heat source settings

Auto emergency

When the heat pump fails to operate, the gas boiler can serve as an emergency back-up heater and either automatically or nonautomatically take over the entire heat load. When auto emergency is set to : Automatic and a heat pump failure occurs, the boiler will automatically take over the heat load. When a heat pump failure occurs and auto emergency is set to Manual the domestic hot water and space heating operations will stop and need to be recovered manually. The user interface will then ask the user to confirm whether the boiler can take over the entire heat load or not. When the heat pump fails, will appear on the user interface. If the house is unattended for longer periods, we recommend that setting [A.5.1.2] Emergency shall be set to Automatic.

# Code Description

[A.5.2.1] N/A Defines whether in an emergency

situation the gas boiler is allowed to automatically take over the entire heat load or whether manual confirmation is required.

▪ 0: Manual (default)

▪ 1: Automatic

INFORMATION

The auto emergency setting can be set in the menu structure of the user interface only.

INFORMATION

If a heat pump failure occurs and [A.5.1.2] is set to Manual, the room frost protection function, the underfloor heating screed dryout function, and the water pipe antifreeze function will remain active even if the user does NOT confirm emergency operation.

Equilibrium temperature

Based on the ambient temperature, energy prices and the required leaving water temperature, the user interface is able to calculate which heat source can deliver the required heating capacity most efficiently. However, to maximise the energy output of the heat pump, it is possible to prevent the gas boiler from operating when the ambient temperature exceeds a certain point (e.g. 5°C). This can be useful to avoid too much gas boiler operation in case of incorrect settings. When an equilibrium temperature is set, domestic hot water operation is NEVER prohibited.

Auto-restart

When power returns after a power supply failure, the auto restart function reapplies the remote controller settings at the time of the power failure. Therefore, it is recommended to always enable the function.

If the preferential kWh rate power supply is of the type that power supply is interrupted, always enable the auto restart function. Continuous indoor unit control can be guaranteed independent of the preferential kWh rate power supply status, by connecting the indoor unit to a normal kWh rate power supply.

Power saving function

Defines whether the outdoor unit power supply can be interrupted (internally by indoor unit control) during stand-still conditions (no space heating/cooling by the heat pump). The final decision to allow power interruption of the outdoor unit during standstill depends on the ambient temperature, compressor conditions and minimum internal timers.

To enable the power saving function setting, [E‑08] needs to be enabled on the user interface in combination with the removal of the power saving connector at the outdoor unit.

9 Operation

9.1 Overview: Operation

The gas boiler is a modulating, high-efficiency boiler. This means that the power is adjusted in line with the desired heat requirement. The aluminium heat exchanger has 2 separate copper circuits. As a result of the separately constructed circuits for space heating and domestic hot water, the heating and the hot water supply can operate independently, but not simultaneously.

The gas boiler has an electronic boiler controller which does the following when heating or hot water supply is required:

▪ starting the fan,

▪ opening the gas valve,

▪ igniting the burner,

▪ constantly monitoring and controlling the flame.

It is possible to use the boiler's domestic hot water circuit without connecting and filling the central heating system.

9.2 Heating

Heating is controlled by the indoor unit. The boiler will start-up the heating process when there is a request from the indoor unit.

9.3 Domestic hot water

Domestic hot water is supplied by the boiler. Because supplying domestic hot water has priority over space heating, the boiler will switch to domestic hot water mode whenever there is a hot water demand. When a simultaneous space heating and domestic hot water demand occurs:

▪ during heat pump only operation (space heating mode), the heat

pump will provide heat while the boiler is bypassed and switches to domestic hot water mode to provide domestic hot water.

▪ during boiler only operation, and with the boiler in domestic hot

water mode, space heating will NOT be provided, but domestic hot water will.

▪ during simultaneous heat pump and boiler operation, the heat

pump will provide heat and the boiler will be bypassed and switch to domestic hot water mode to provide domestic hot water.

9.3.1 Flow resistance graph for appliance domestic hot water circuit

The minimum flow for domestic hot water operation is 1.5l/min. The minimum pressure is 0.1 bar. A low flow (<5 l/min) can reduce comfort. Make sure to set the setpoint high enough.

Installer reference guide

9.4 Operation modes

The following codes on the service display indicate the following operating modes.

Off

The gas boiler is out of operation but is supplied with electric power. There will be no response on space heating and/or domestic hot water demands. Frost protection is active. This means that the exchanger is heated up if the water temperature in the gas boiler is too low. If applicable, the keep hot function will also be active.

If frost protection or keep hot function is activated, will be displayed (heating the exchanger). In this mode, the pressure (bar) in the space heating installation can be read on the main display.

Waiting mode (blank service display)

The LED at the button is lit and possibly also one of the LEDs for the domestic hot water comfort function. The gas boiler is waiting for a space heating and/or domestic hot water demand.

Pump overrun of space heating

After each space heating operation, the pump continues to run. This function is controlled by the indoor unit.

Boiler shutdown when the required temperature is reached

The boiler controller can temporarily stop the requested space heating demand. The burner will stop. The shutdown occurs because the requested temperature is reached. When the temperature drops too fast and the anti-cycle time has passed, the shutdown will be cancelled.

Self-test

The sensors check the boiler controller. During the check-up, the boiler controller does NOT perform any other tasks.

Ventilation

When the appliance is started, the fan goes to starting speed. When the starting speed is reached, the burner is lit. The code will also be visible when post-ventilation is taking place after the burner has stopped.

Ignition

When the fan has reached its starting speed, the burner is ignited by means of electric sparks. During ignition the code will be visible on the service display. If the burner does NOT ignite, a new ignition attempt occurs after 15 seconds. If after 4 ignition attempts the burner is NOT yet burning, the boiler will go into fault mode.

Domestic hot water operation

The domestic hot water supply has priority over space heating performed by the gas boiler. If the flow sensor detects a domestic hot water demand of more than 2l/min, space heating by the gas boiler will be interrupted. After the fan has reached speed code and ignition is done, the boiler controller goes into domestic hot water mode.

During the domestic hot water operation, the fan speed and hence the appliance power are controlled by the gas boiler controller so that the domestic hot water temperature reaches the domestic hot water temperature setting.

The domestic hot water supply temperature must be set on the user interface of the hybrid module. See the user reference guide for more details.

10 Commissioning

space heating operation

When a space heating request is received from the indoor module, the fan is started, followed by the ignition, and the space heating operation mode. During the space heating operation, the fan speed and hence the appliance power are controlled by the gas boiler controller so that the space heating water temperature reaches the desired space heating supply temperature. During the space heating operation, the requested space heating supply temperature is indicated on the operating panel.

The space heating supply temperature must be set on the user interface of the hybrid module. See the user reference guide for more details.

10 Commissioning

Especially for UK:

At the time of commissioning, complete all relevant sections of the Benchmark Checklist on the backpages of this document.

10.1 Overview: Commissioning

There are NO damaged components or squeezed pipes on the inside of the indoor and outdoor units.

There are NO refrigerant leaks.

10.2 Precautions when commissioning

INFORMATION

During the first running period of the unit, the required power may be higher than stated on the nameplate of the unit. This phenomenon is caused by the compressor, that needs a continuous run time of 50 hours before reaching smooth operation and stable power consumption.

NOTICE

Before starting up the system, the unit MUST be energised for at least 2hours. The crankcase heater needs to heat up the compressor oil to avoid oil shortage and compressor breakdown during startup.

NOTICE

NEVER operate the unit without thermistors and/or pressure sensors/switches. Burning of the compressor might result.

NOTICE

Do NOT operate the unit until the refrigerant piping is complete (when operated this way, the compressor will break).

10.3 Checklist before commissioning

Do NOT operate the system before the following checks are OK:

You read the complete installation instructions, as described in the installer reference guide.

The refrigerant pipes (gas and liquid) are thermally insulated.

The correct pipe size is installed and the pipes are properly insulated.

There is NO water leak inside the indoor unit.

There is NO water leak inside the gas boiler.

There is NO water leak in the connection between the gas boiler and the indoor unit.

The shut-off valves are properly installed and fully open (field supply).

The stop valves (gas and liquid) on the outdoor unit are fully open.

The air purge valve is open (at least 2 turns).

The pressure relief valve purges water when opened.

10.4.2 Air purge function

When commissioning and installing the unit, it is very important to remove all air in the water circuit. When the air purge function is running, the pump operates without actual operation of the unit and the removal of air in the water circuit will start.

NOTICE

Before starting the air purge, open the safety valve and check if the circuit is sufficiently filled with water. Only if water escapes the valve after opening it, you can start the air purge procedure.

There are 2 modes for purging air:

▪ Manually: the unit will operate with a fixed pump speed (high or

low), which can be set. The position of the 3-way valve for the optional domestic hot water tank as well as that of the gas boiler's bypass valve can also be set. To ensure all air will be removed, however, it is recommended NOT to adjust their custom position.

Installer reference guide

In case the actual flow rate is below the minimum flow rate, modifications at the hydraulic configuration are required. Increase the space heating loops that can NOT be closed or install a pressure‑controlled bypass valve.

▪ Automatic: the pump alternates between high speed, low speed

and standstill position. The position of the 3-way valve automatically alternates between that for space heating and that for domestic hot water heating. The gas boiler is continuously bypassed. To remove air from the gas boiler, perform a manual air purge on the gas boiler.

Typical workflow

Purging the air from the system should consist of:

1 Performing a manual air purge

2 Performing an automatic air purge

INFORMATION

Start by performing a manual air purge. When almost all the air is removed, perform an automatic air purge. If necessary, repeat performing the automatic air purge until you are sure that all air is removed from the system. During air purge function, pump speed limitation [9‑0D] is NOT applicable.

Air purge prerequisites

3 Install air purges on each part of the installation where the pipe

work goes down. (For example on a tank with connections on top.)

4 Fill the circuit to ±2bar.

5 Purge all radiators and all other air purges installed on the

circuit.

6 Repeat steps 2 and 3 until purging the radiators and the other

points does NOT longer lead to a pressure drop.

7 Make sure that the leaving water temperature home page, room

temperature home page, and domestic hot water home page are turned OFF.

When an air bubble blocks the pump and there is no flow, a 7H error can occur. In this case, stop the air purge function and restart the operation. This will cause the bubble to leave the pump. Make sure the pressure in the circuit is ±2bar and refill if necessary.

To check if the air purge function is finished, monitor the flow rate. If it stays constant when the pump is running at high or low speed, the unit is properly purged. To monitor the flow rate, go to [6.1.8].

The air purge function automatically stops after 42minutes.

To perform a manual air purge

Prerequisite: Make sure that the leaving water temperature home

page, room temperature home page, and domestic hot water home page are turned OFF.

14.2 To pump down

Example: To protect the environment, pump down when relocating

the unit or when disposing of the unit.

NOTICE

During pump down operation, stop the compressor before removing the refrigerant piping. If the compressor is still running and the stop valve is open during pump down, air will be sucked into the system. Compressor breakage and other injury will be the result due to abnormal pressure in the refrigerant cycle.

Pump down operation will extract all refrigerant from the system into the outdoor unit.

1 Remove the valve lid from liquid stop valve and gas stop valve.

2 Carry out the forced cooling operation.

3 After 5 to 10 minutes (after only 1 or 2 minutes in case of very

low ambient temperatures (<−10°C)), close the liquid stop valve with a hexagonal wrench.

4 Check with the manifold if the vacuum is reached.

5 After 2-3 minutes, close the gas stop valve and stop forced

cooling operation.
