1 General safety precautions

DANGER: RISK OF EXPLOSION

Pump down – Refrigerant leakage. If you want to pump

down the system, and there is a leakage in the refrigerant circuit:

▪ Do NOT use the unit's automatic pump down function,

with which you can collect all refrigerant from the system into the outdoor unit. Possible consequence: Self-combustion and explosion of the compressor because of air going into the operating compressor.

▪ Use a separate recovery system so that the unit's

compressor does NOT have to operate.

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")

A siphon tube is NOT present Charge with the cylinder upside

Charge with the cylinder upright.

down.

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.

1.2.4 Brine

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

WARNING

The selection of the brine MUST be in accordance with the applicable legislation.

WARNING

Take sufficient precautions in case of brine leakage. If brine leaks, ventilate the area immediately and contact your local dealer.

WARNING

The ambient temperature inside the unit can get much higher than that of the room, e.g. 70°C. In case of a brine leak, hot parts inside the unit can create a hazardous situation.

WARNING

The use and installation of the application MUST comply with the safety and environmental precautions specified in the applicable legislation.

1.2.5 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.

1.2.6 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.

▪ Open refrigerant cylinders slowly.

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

prevent normal operation.

2 About the documentation

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.

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.

This chapter contains application guidelines for:

▪ Setting up the space heating/cooling system

▪ Setting up an auxiliary heat source for space heating

▪ Setting up the energy metering

▪ Setting up the power consumption

▪ Setting up an external temperature sensor

5.2 Setting up the space heating/ cooling system

The heatpump system supplies leaving water to heat emitters in one or more rooms.

Because the system offers a wide flexibility to control the temperature in each room, you need to answer the following questions first:

▪ How many rooms are heated or cooled by the Daikin heatpump

system?

▪ Which heat emitter types are used in each room and what is their

design leaving water temperature?

Once the space heating/cooling requirements are clear, Daikin recommends to follow the setup guidelines below.

NOTICE

If an external room thermostat is used, the external room thermostat will control the room frost protection. However, the room frost protection is only possible if the leaving water temperature control on the unit's user interface is turned ON.

INFORMATION

In case an external room thermostat is used and room frost protection needs to be guaranteed in all conditions, then you have to set auto emergency [A.6.C] to 1.

5.2.2 Multiple rooms – OneLWT zone

If only one leaving water temperature zone is needed because the design leaving water temperature of all heat emitters is the same, you do NOT need a mixing valve station (cost effective).

Example: If the heat pump system is used to heat up one floor where all the rooms have the same heat emitters.

Underfloor heating or radiators – Thermostatic valves

If you are heating up rooms with under floor heating or radiators, a very common way is to control the temperature of the main room by using a thermostat (this can either be the user interface connected to control box EKCB07CAV3, or an external room thermostat), while the other rooms are controlled by so-called thermostatic valves (field supply), which open or close depending on the room temperature.

Setup

▪ The fancoil units are directly connected to the outdoor unit – or to

the backup heater, if there is one.

▪ A shut-off valve (field supply) is installed before the under floor

heating to prevent condensation on the floor during cooling operation.

▪ The desired room temperature is set via the remote controller of

the fancoil units.

▪ A space heating/cooling demand signal is sent to one digital input

on control box EKCB07CAV3 (X2M/1 and X2M/2) (if this signal is available on the fan coil unit and compatible with the control box).

5.3 Setting up an auxiliary heat source for space heating

▪ Space heating can be done by:

▪ The outdoor unit

▪ An auxiliary boiler (field supply) connected to the system

Installer reference guide

▪ When the room thermostat requests heating, the outdoor unit or

the auxiliary boiler starts operating depending on the outdoor temperature (status of the changeover to external heat source). When the permission is given to the auxiliary boiler, the space heating by the outdoor unit is turned OFF.

▪ Bivalent operation is only possible for space heating.

INFORMATION

For bivalent operation to be possible, the system requires option box EK2CB07CAV3.

INFORMATION

▪ During heating operation of the heat pump, the

heat pump operates to achieve the desired temperature set via the user interface. When weatherdependent operation is active, the water temperature is determined automatically depending on the outdoor temperature.

▪ During heating operation of the auxiliary boiler, the

auxiliary boiler operates to achieve the desired water temperature set via the auxiliary boiler controller.

Calculating the consumed energy

▪ The consumed energy is calculated internally based on:

▪ The actual power input of the outdoor unit

▪ The set capacity of the optional backup heater

▪ The voltage

▪ Setup and configuration: To get accurate energy data, measure

the capacity (resistance measurement) and set the capacity via the user interface for the optional backup heater (step 1 and step2).

Measuring the consumed energy

▪ Preferred method because of higher accuracy.

▪ Setup and configuration:

▪ Requires option box EK2CB07CAV3.

▪ Requires external power meters.

▪ When using electrical power meters, set the number of pulses/

kWh for each power meter via the user interface.

INFORMATION

When measuring the electrical power consumption, make sure ALL power input of the system is covered by the electrical power meters.

5.4.3 Normal kWh rate power supply

General rule

One power meter that covers the entire system is sufficient.

Setup

▪ Install control box EKCB07CAV3 and option box EK2CB07CAV3.

▪ Connect the power meter to X2M/7 and X2M/8 of option box

EK2CB07CAV3.

5.5 Setting up the power consumption control

▪ The power consumption control:

▪ Allows you to limit the power consumption of the entire system

(sum of the outdoor unit, control box EKCB07CAV3, option box EK2CB07CAV3, and the backup heater kit).

▪ Configuration: Set the power limitation level and how it has to

be achieved via the user interface.

▪ The power limitation level can be expressed as:

▪ Maximum running current (inA)

▪ Maximum power input (inkW)

▪ The power limitation level can be activated:

▪ Permanently

▪ By digital inputs

5 Application guidelines

Setup and configuration

▪ No additional equipment needed.

▪ Set the power consumption control settings in [A.6.3.1] via the

user interface (for the description of all settings, see

"8Configuration"on page46):

▪ Select full time limitation mode

▪ Select the type of limitation (power in kW or current in A)

▪ Set the desired power limitation level

NOTICE

Mind the following guidelines when selecting the desired power limitation level:

▪ Set a minimum power consumption of ±3.6 kW to

guarantee defrost operation. Otherwise, if defrosting is interrupted several times, the heat exchanger will freeze up.

▪ Set a minimum power consumption of ±3 kW to

guarantee space heating by allowing backup heater step1.

5.5.2 Power limitation activated by digital inputs

Power limitation is also useful in combination with an energy management system.

The power or current of the entire Daikin system is limited dynamically by digital inputs (maximum four steps). Each power limitation level is set via the user interface by limiting one of the following:

▪ Current (in A)

▪ Power input (in kW)

The energy management system (field supply) decides the activation of a certain power limitation level. Example: To limit the maximum power of the entire house (lighting, domestic appliances, space heating…).

5.5.1 Permanent power limitation

Permanent power limitation is useful to assure a maximum power or current input of the system. In some countries, legislation limits the maximum power consumption for space heating.

Setup

▪ Install control box EKCB07CAV3 and option box EK2CB07CAV3.

▪ Maximum four digital inputs are used to activate the

corresponding power limitation level:

▪ DI1 = weakest limitation (highest energy consumption)

▪ DI4 = strongest limitation (lowest energy consumption)

▪ For the specifications of the digital inputs, and for where to

connect them, refer to the wiring diagram.

Configuration

Set the power consumption control settings in [A.6.3.1] via the user interface (for the description of all settings, see "8Configuration"on

page46):

▪ Select activation by digital inputs.

▪ Select the type of limitation (power in kW or current in A).

▪ Set the desired power limitation level corresponding to each digital

input.

INFORMATION

In case more than 1 digital input is closed (at the same time), the digital input priority is fixed: DI4 priority>…>DI1.

5.5.3 Power limitation process

The outdoor unit has better efficiency than the backup heater. Therefore, the backup heater is limited and turned OFF first. The system limits power consumption in the following order:

1 Limits the backup heater.

2 Turns OFF the backup heater.

3 Limits the outdoor unit.

4 Turns OFF the outdoor unit.

Example

If the configuration is as follows: Power limitation level does NOT allow for backup heater operation (step1 and step2).

Then power consumption is limited as follows:

5.6 Setting up an external temperature sensor

You can connect one external temperature sensor. It can measure the indoor or outdoor ambient temperature. Daikin recommends to use an external temperature sensor in the following cases:

Indoor ambient temperature

▪ In room thermostat control, the user interface is used as room

thermostat and it measures the indoor ambient temperature. Therefore, the user interface must be installed on a location:

▪ Where the average temperature in the room can be detected

▪ That is NOT exposed to direct sunlight

▪ That is NOT near a heat source

▪ That is NOT affected by outside air or air draught because of,

for example, door opening/closing

▪ If this is NOT possible, Daikin recommends to connect a remote

indoor sensor (option KRCS01-1).

▪ Setup:

▪ Requires control box EKCB07CAV3 and option box

EK2CB07CAV3.

▪ For installation instructions, see the installation manual of the

remote indoor sensor and the addendum book for optional equipment.

Configuration: Select room sensor [A.2.2.F.5].

Outdoor ambient temperature

▪ In the outdoor unit, the outdoor ambient temperature is measured.

Therefore, the outdoor unit must be installed on a location:

▪ At the north side of the house or at the side of the house where

the most heat emitters are located

▪ That is NOT exposed to direct sunlight

▪ If this is NOT possible, Daikin recommends to connect a remote

outdoor sensor (option EKRSCA1).

▪ Setup: For installation instructions, see the installation manual of

the remote outdoor sensor and the addendum book for optional equipment.

▪ Configuration: Select outdoor sensor [A.2.2.B].

▪ When the power saving functionality of the outdoor unit is active

(see "8 Configuration" on page 46), the outdoor unit is turned down to reduce standby energy losses. As a result, the outdoor ambient temperature is NOT read out.

▪ If the desired leaving water temperature is weather dependent, the

full time outdoor temperature measurement is important. This is another reason to install the optional outdoor ambient temperature sensor.

INFORMATION

The external outdoor ambient sensor data (either averaged or instantaneous) is used in the weather-dependent control curves and in the automatic heating/cooling changeover logic. To protect the outdoor unit, the internal sensor of the outdoor unit is always used.

▪ 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.

NOTICE

If glycol is present in the system, make sure the thread sealant used is resistant to glycol.

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

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

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

the required water flow and the available external static pressure of the pump. See "14 Technical data"on page77 for the external static pressure curves of the outdoor unit.

▪ Water flow. It is required to guarantee a minimum flow of 12l/min.

When the flow is lower, the system will stop operation and display error 7H.

INFORMATION

If the backup heater is installed in a reversible system (heating+cooling) and valve kit EKMBHBP1 is part of the system, it may be required to provide more space under the backup heater than indicated above. For more information, refer to "7.7.5 About the valve kit" on

page34.

▪ The backup heater is designed to be wall-mounted in indoor

locations only. Make sure the installation surface is a flat and vertical non-combustible wall.

▪ The backup heater is designed to operate in ambient

temperatures ranging from 5~30°C.

Do NOT install the backup heater in the following places:

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

operation noise will cause no trouble.

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

bathroom.

▪ In places where frost is possible.

▪ Field supply components – Freeze protection. If negative

ambient temperatures are expected, make sure the outdoor field piping is sufficiently protected against freezing. Depending on the outdoor unit model, add glycol to the water circuit, or add sufficient insulation and/or heater tape to the outdoor field piping. For details, see "7.7.6To protect the water circuit against freezing"on

page35.

▪ Field supply components – Water and glycol. Only use

materials that are compatible with the water (and, if applicable, glycol) used in the system, and with the materials used in the outdoor 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. All installed piping and piping accessories

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

INFORMATION

The following illustration is an example and might NOT match your system layout.

NOTICE

In case of plastic pipes, make sure they are fully oxygen diffusion tight according to DIN 4726. The diffusion of oxygen into the piping can lead to excessive corrosion.

▪ 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. The outdoor unit has a manual air purge valve. The backup heater (option) has an automatic air purge valve. Check that automatic air purge valves are NOT tightened too much, so that the automatic release of air from 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 – 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.

▪ Thermostatic mixing valves. In accordance with the applicable

legislation, it may be necessary to install thermostatic mixing valves.

▪ Hygienic measures. The installation must be in compliance with

the applicable legislation and may require additional hygienic installation measures.

6.3.2 Formula to calculate the expansion vessel pre-pressure

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

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

Installer reference guide

6.3.3 To check the water volume and flow rate

The outdoor unit has an expansion vessel of 3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.

When changing the default pre-pressure of the expansion vessel (1bar) is required, take following guidelines into account:

▪ Only use dry nitrogen to set the expansion vessel pre-pressure.

▪ 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 Schrader valve of the expansion vessel.

a Schrader valve

6.3.5 To check the water volume: Examples

Example 1

The outdoor unit is installed 0.8 m below the highest point in the water circuit. The total water volume in the water circuit is 50l.

No actions or adjustments are required.

Example 2

The outdoor unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 140l. The concentration of propylene glycol is 35%.

Actions:

▪ Because the total water volume (140 l) is more than the default

water volume (43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 66l. (See

the graph in the chapter above).

▪ Because 140l is more than 66l, the expansion vessel is NOT

appropriate for the installation. Therefore the system requires an external expansion vessel.

6.4 Preparing electrical wiring

6.4.1 About preparing electrical wiring

INFORMATION

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

WARNING

The backup heater MUST have a dedicated power supply and MUST be protected by the safety devices required by the applicable legislation.

WARNING

ALWAYS use multicore cable for power supply cables.

6.4.2 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, if any.

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.

Installer reference guide

▪ If the power supply has a missing or wrong N-phase,

equipment might break down.

▪ Establish proper earthing. Do NOT earth the unit to a

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

▪ Install the required fuses or circuit breakers.

▪ Secure the electrical wiring with cable ties so that the

cables do NOT come in contact with sharp edges or piping, particularly on the high-pressure side.

▪ Do NOT use taped wires, stranded conductor wires,

extension cords, or connections from a star system. They can cause overheating, electrical shock or fire.

▪ Do NOT install a phase advancing capacitor, because

this unit is equipped with an inverter. A phase advancing capacitor will reduce performance and may cause accidents.

▪ All wiring must be performed by an authorized

electrician and must comply with the applicable legislation.

▪ Make electrical connections to the fixed wiring.

▪ All components procured on the site and all electrical

construction must comply with the applicable legislation.

Control box EKCB07CAV3 is designed to receive an input signal by which it switches the outdoor unit into forced-off mode. At that moment, the compressor will not operate.

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

7.7.6 To protect the water circuit against freezing

Frost can damage the system. For this reason, if negative ambient temperatures are expected, make sure the water circuit is sufficiently protected against freezing. Freeze protection is model-dependent. Either add glycol to the water circuit, or provide the outdoor field piping with heater tape, according to the table below.

If … … then

Standard model (no -H- in the model name)

Heater tape model (-H- in the model name)

Heater tape (field supply)

1 Install heater tape to the outdoor field piping.

2 Provide external power supply for the heater tape.

NOTICE

▪ For the internal heater tape to operate, the power to the

unit MUST be ON. For this reason, during cold periods, never disconnect the power, nor turn off the main switch.

▪ In case of a power failure, power to the heater tape

(both internal and external) will be aborted and the water circuit will NOT be protected. To guarantee a full protection, it is always possible to add glycol to the water circuit, even when installing heater tape to the outdoor field piping.

Glycol

The required concentration of glycol depends on the lowest expected outdoor temperature, and on whether you want to protect the system from bursting or from freezing. To prevent the system from freezing, more glycol is required. Add glycol according to the table below.

Add glycol to the water circuit, according to the instructions below. In this way, you protect the internal water piping, as well as the outdoor field piping.

The internal water piping is factory‑equipped with heater tape and additional insulation, this to prevent it from freezing. To prevent the outdoor field piping from freezing, provide it with sufficient insulation or heater tape (field supply), according to the instructions below.

7 To provide stress relief, fix the power supply cable to the 3‑way

valve body with a cable tie (field supply). Fix it so that possible condensate cannot enter the 3‑way valve motor via the cable.

be able to start. Mind that if you only prevent the system from bursting, the liquid inside might still freeze.

▪ In case of a power supply failure or pump failure, and

NO glycol was added to the system, drain the system.

▪ When water is at standstill inside the system, the

system is very likely to freeze and get damaged.

The following types of glycol are allowed:

▪ Ethylene glycol;

▪ Propylene glycol, including the necessary inhibitors, classified as

CategoryIII according to EN1717.

WARNING

Due to presence of glycol, corrosion of the system is possible. Uninhibited glycol will turn acidic under the influence of oxygen. This process is accelerated by the presence of copper and high temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system. Therefore it is important that:

▪ the water treatment is correctly executed by a qualified

water specialist,

▪ a glycol with corrosion inhibitors is selected to

counteract acids formed by the oxidation of glycols,

▪ no automotive glycol is used because their corrosion

inhibitors have a limited lifetime and contain silicates which can foul or plug the system,

▪ galvanized pipes are NOT used in glycol systems since

the presence may lead to the precipitation of certain components in the glycol's corrosion inhibitor.

Adding glycol to the water circuit reduces the maximum allowed water volume of the system. For more information, refer to the chapter "To check the water volume and flow rate" in the installer reference guide.

7.7.7 To fill the water circuit

1 Connect the water supply hose to the drain and fill valve.

WARNING

Ethylene glycol is toxic.

NOTICE

Glycol absorbs water from its environment. Therefore do NOT add glycol that has been exposed to air. Leaving the cap off the glycol container causes the concentration of water to increase. The glycol concentration is then lower than assumed. As a result, the hydraulic components might freeze up after all. Take preventive actions to ensure a minimal exposure of the glycol to air.

NOTICE

▪ If overpressure occurs, the system will release some of

the liquid through the pressure relief valve. If glycol was added to the system, take adequate measures so as to safely recover it.

▪ In any case, make sure that the flexible hose of the

pressure relief valve is ALWAYS free to release pressure. Prevent water from staying and/or freezing up inside the hose.

2 Open the drain and fill valve.

3 If an automatic air purge valve was installed, make sure it is

open.

4 Fill the circuit with water until the manometer (field supply)

indicates a pressure of ±2.0bar.

5 Purge as much air as possible from the water circuit. For

instructions, see "9Commissioning"on page66.

6 Refill the circuit until the pressure is ±2.0bar.

7 Repeat steps 5 and 6 until no more air is purged and there are

no more pressure drops.

8 Close the drain and fill valve.

9 Disconnect the water supply hose from the drain and fill valve.

Installer reference guide

NOTICE

The water pressure indicated on the manometer will vary depending on the water temperature (higher pressure at higher water temperature).

However, at all times water pressure shall remain above 1bar to avoid air entering the circuit.

7.7.8 To insulate the water piping

The piping in the complete water circuit MUST be insulated to prevent condensation during cooling operation and reduction of the heating and cooling capacity.

To prevent the freezing of the outdoor water piping during winter time, the thickness of the sealing material MUST be at least 13mm (with λ=0.039W/mK).

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.

During winter, protect the water piping and shut‑off valves against freezing by adding heat tape (field supply). If the outdoor temperature can drop below –20°C and no heat tape is used, it is recommended to install the shut‑off valves indoors.

8.2.5 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 5°C.

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

Leaving water temperature: Delta T source

Temperature difference for entering and leaving water. The unit is designed to support under floor loops operation. The recommended leaving water temperature (set by the user interface) for under floor loops is 35°C. In such case, the unit will be controlled to realize a temperature difference of 5°C which means that the entering water to the unit is around 30°C. Depending on the installed application (radiators, under floor loops) or situation, it can be possible to change the difference between entering and leaving water temperature. Note that the pump will regulate its flow to keep the Δt.

modulation, the desired leaving water temperature will be calculated automatically by the unit (based on the preset temperatures, if weather-dependent is selected, modulation will be done based on the desired weather-dependent temperatures); when turning off the modulation, you can set the desired leaving water temperature on the user interface. Moreover, with the modulation turned on, the desired leaving water temperature is lowered or raised in function of the desired room temperature and the difference between the actual and the desired room temperature. This results in:

▪ stable room temperatures exactly matching the desired

temperature (higher comfort level)

▪ less On/OFF cycles (lower noise level, higher comfort and higher

efficiency)

▪ water temperatures as low as possible to match the desired

temperature (higher efficiency)

# Code Description

▪ 0 (No): disabled.

Note: The desired leaving water temperature needs to be set on the user interface.

▪ 1 (Yes)(default): enabled. The

leaving water temperature is calculated according to the difference between the desired and the actual room temperature. This creates a better match between the capacity of the heat pump and the actual required capacity, and results in less start/stop cycles and a more economic operation. Note: The desired leaving water temperature can only be read out on the user interface

modulation:

0°C~10°C (default: 3°C)

Requires modulation to be enabled.

This is the value by which the desired leaving water temperature is increased or lowered.

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. Refer to the illustration below.

Leaving water temperature: Emitter type

Only applicable in case of room thermostat control. Depending on the system water volume and the heat emitters type, the heat up or cool down of a space can take longer. This setting can compensate for a slow or a quick heating/cooling system during the heat up/cool down cycle.

Note: The setting of the emitter type will influence the maximum modulation of the desired leaving water temperature and the possibility for usage of the automatic cooling/heating changeover based on the indoor ambient temperature.

Therefore it is important to set this correctly.

Preset leaving water temperature

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

Select preset leaving water temperatures in accordance with the design and selected heat emitters to ensure the balance between desired room and leaving water temperatures.

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.

N/A [9-04] 1°C~4°C (default: 1°C)

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).

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).

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

ONLY applicable for EWYQ004+005BAVP.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46).

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 rises 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.

Auto emergency

When the heat pump fails to operate, the backup heater can serve as an emergency heater and either automatically or nonautomatically take over the heat load.

▪ When auto emergency is set to Automatic and a heat pump failure

occurs, the backup heater will automatically take over the heat load.

▪ When auto emergency is set to Manual and a heat pump failure

occurs, space heating operation will stop and needs to be recovered manually. The user interface will then ask you to confirm whether the backup heater can take over the 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 to set [A.6.C] Emergency to Automatic.

N/A [F‑00] Pump operation:

▪ 0: Disabled if outdoor temperature is

higher than [4‑02] or lower than [F‑01] depending on heating/cooling operation mode.

▪ 1: Possible at all outdoor

temperatures.

Pump operation during flow abnormality [F‑09] defines whether the pump stops at flow abnormality or allow to continue operation when flow abnormality occurs. This functionality is only valid in specific conditions where it is preferable to keep the pump active when Ta<4°C (pump will be activated for 10 minutes and deactivated after 10 minutes). Daikin shall NOT be held liable for any damage resulting this functionality.

# Code Description

N/A [F‑09] Pump continue operation when flow

abnormality:

▪ 0: Pump will be deactivated.

▪ 1: Pump will be activated when

Ta<4°C (10 minutes ON – 10 minutes OFF)

INFORMATION

If glycol is present in the system ([E‑0D] set to "1") and a flow abnormality occurs, then [F‑09] will have NO effect, and the pump will continue operation (intervals of 20 minutes ON – 4 minutes OFF).

Pump speed limitation

Pump speed limitation [9‑0D] defines the maximum pump speed. In normal conditions, the default setting should NOT be modified. The pump speed limitation will be overruled when the flow rate is in the range of the minimum flow (error 7H).

# Code Description

N/A [9‑0D] Pump speed limitation

▪ 0: No limitation.

▪ 1~4: General limitation. There is

limitation in all conditions. The required delta T control and comfort are NOT guaranteed.

▪ 5~8 (default: 6): Limitation when no

actuators. When there is no heating/ cooling output, the pump speed limitation is applicable. When there is heating/cooling output, the pump speed is only determined by delta T in relation to the required capacity. With this limitation range, delta T is possible and the comfort is guaranteed.

The maximum values depend on the unit type:

Pump operation

When the pump operation function is disabled the pump will stop if the outdoor temperature is higher than the value set by [4‑02] or if the outdoor temperature drops below the value set by [F‑01]. When the pump operation is enabled, the pump operation is possible at all outdoor temperatures.

9 Commissioning

9.1 Overview: Commissioning

This chapter describes what you have to do and know to commission the system after it is configured.

Typical workflow

Commissioning typically consists of the following stages:

1 Checking the "Checklist before commissioning".

2 Performing an air purge.

3 Performing a test run for the system.

4 If necessary, performing a test run for one or more actuators.

5 If necessary, performing an underfloor heating screed dryout.

9.2 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

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

9.3 Checklist before commissioning

Do NOT operate the system before the following checks are OK. Depending on the system layout, not all components may be available.

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

The outdoor unit is properly mounted.

The control box is properly mounted.

The option box is properly mounted.

Only if you use the optional backup heater:

The backup heater is properly mounted.

The following field wiring has been carried out according to the available documentation and the applicable legislation:

▪ Between the local supply panel and the outdoor unit

▪ Between the outdoor unit and the control box

▪ Between the control box and the option box

▪ Between the control box and the backup heater

▪ Between the local supply panel and the control box

▪ Between the local supply panel and the option box

▪ Between the outdoor unit and the valves

▪ Between the control box and the room thermostat

The system is properly earthed and the earth terminals are tightened.

The fuses or locally installed protection devices are installed according to this document, and have not been bypassed.

The power supply voltage matches the voltage on the identification label of the unit.

There are NO loose connections or damaged electrical components in the switchbox.

There are NO damaged components or squeezed pipes on the inside of the outdoor unit.

Only if you use the optional backup heater:

Depending on the backup heater type, backup heater circuit breaker F1B (on the switch box of the backup heater) is turned ON.

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

There are no water leaks inside the outdoor unit.

The shut-off valves are properly installed and fully open.

The pressure relief valve purges water when opened.

The minimum water volume is guaranteed in all conditions. See "To check the water volume" in

"6.3Preparing water piping"on page23.

The water circuit is properly protected against freezing, according to the instructions set out in "7.7.6To

protect the water circuit against freezing"on page35.

If glycol was added to the system, confirm the correct glycol concentration, and check if glycol setting [E‑0D]=1.

NOTICE

▪ Make sure glycol setting [E-0D] matches the liquid

inside the water circuit (0=water only, 1=water+glycol). If the glycol setting is NOT set correctly, the liquid inside the piping can freeze.

▪ When glycol is added to the system, but the glycol

concentration is lower than prescribed, the liquid inside the piping can still freeze.

INFORMATION

The software is equipped with an "installer-on-site" mode ([4‑0E]), that disables automatic operation by the unit. At first installation, setting [4‑0E] is by default set to "1", meaning automatic operation is disabled. All protective functions are then disabled. If the user interface home pages are off, the unit will NOT operate automatically. To enable automatic operation and the protective functions, set [4‑0E] to "0".

36 hours after the first power-on, the unit will automatically set [4‑0E] to "0", ending "installer-on-site" mode and enabling the protective functions. If – after first installation – the installer returns to the site, the installer has to set [4‑0E] to "1" manually.

04+05 models 12l/min

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.

9.4.2 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 and in a

fixed or custom position of the 3-way valve. The custom position of the 3-way valve is a helpful feature to remove all air from the water circuit in the space heating mode. The operation speed of the pump (slow or quick) can also be set.

▪ Automatic: the unit automatically changes the pump speed.

Typical workflow

Purging the air from the system should consist of:

1 Performing a manual air purge

2 Performing an automatic air purge

NOTICE

The outdoor unit is equipped with a manual air purge valve. The air purge procedure requires manual action.

NOTICE

When purging air with the manual air purge valve of the unit, collect any fluid that might leak out of the valve. If this fluid is NOT collected, it might drip on internal components and damage the unit.

EWAQ+EWYQ004+005BAVP Packaged air-cooled water chillers and packaged air to water heat pumps 4P492900-1 – 2017.06

INFORMATION

▪ To purge air, use all air purge valves present in the

system. This includes the manual air purge valve of the outdoor unit, as well as any field-supplied valves.

▪ If the system contains a backup heater, also use the air

purge valve of the backup heater.

▪ If the system contains valve kit EKMBHBP1, it is

required to – during the air purge – manually switch the position of the valve kit's 3‑way valve by turning its knob, this to prevent air from remaining in the bypass. For more information, refer to the instruction sheet of the valve kit.

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.

Make sure that the leaving water temperature home page and room temperature home page are turned OFF.

The air purge function automatically stops after 30minutes.

INFORMATION

When starting up the system in a cold climate, and NO backup heater kit was installed, it may be required to start up with a small water volume. To do this, gradually open the heat emitters. As a result, the water temperature will gradually rise. Monitor the inlet water temperature ([6.1.6] in the menu structure) and make sure it does NOT drop below 15°C.

INFORMATION

If 2 user interfaces are present, you can start a test run from both user interfaces.

▪ The user interface used to start the test run displays a

status screen.

▪ The other user interface displays a "busy" screen. You

cannot use the user interface as long as the "busy" screen is shown.

If the installation of the unit has been done correctly, the unit will start up during test operation in the selected operation mode. During the test mode, the correct operation of the unit can be checked by monitoring the leaving water temperature (heating/cooling mode).

To monitor the temperature, go to [A.6] and select the information you want to check.

9.4.4 To perform an actuator test run

Purpose of the actuator test run is to confirm the operation of the different actuators (e.g., when you select pump operation, a test run of the pump will start).

Prerequisite: Make sure that the leaving water temperature home page and room temperature home page are turned OFF.

1 Set the user permission level to Installer. See "To set the user

9.4.5 Underfloor heating screed dryout

This function is used for drying out the screed of an underfloor heating system very slowly during the construction of a house. It allows the installer to program and execute this program.

Make sure that the leaving water temperature home page and room temperature home page are turned OFF.

If a backup heater kit is part of the system, this function can be executed without finishing the outdoor installation. In this case, the backup heater will perform the screed dryout and supply the leaving water without heat pump operation.

INFORMATION

▪ If Emergency is set to Manual ([A.6.C]=0), and the unit

is triggered to start emergency operation, the user interface will ask confirmation before starting. The underfloor heating screed dryout function is active even if the user does NOT confirm emergency operation.

▪ During underfloor heating screed dryout, pump speed

limitation [9‑0D] is NOT applicable.

NOTICE

The installer is responsible for:

▪ contacting the screed manufacturer for the initial

heating instructions to avoid cracking the screed,

▪ programming the underfloor heating screed dryout

schedule according to the above instruction of the screed manufacturer,

▪ checking the proper functioning of the setup on a

11 Maintenance and service

NOTICE

Maintenance must be done by an authorised installer or service agent.

We recommend to do maintenance at least once a year. However, applicable legislation might require shorter maintenance intervals.

NOTICE

In Europe, the greenhouse gas emissions of the total refrigerant charge in the system (expressed as tonnes CO2-equivalent) is used to determine the maintenance intervals. Follow the applicable legislation.

Formula to calculate the greenhouse gas emissions:

GWP value of the refrigerant × Total refrigerant charge [in kg] / 1000

11.1 Overview: Maintenance and service

This chapter contains information about:

▪ The yearly maintenance of the outdoor unit

▪ The inspection of the backup heater switch box.

▪ The inspection of the control box switch box.

12 Troubleshooting

1 3

▪ Switch box

▪ Glycol concentration

Heat exchanger

The heat exchanger of the outdoor unit can get blocked up due to dust, dirt, leaves, etc. It is recommended to clean the heat exchanger yearly. A blocked heat exchanger can lead to too low pressure or too high pressure leading to worse performance.

Water pressure

Check whether the water pressure is above 1bar. If it is lower, add water.

Water filter

Clean the water filter.

NOTICE

Handle the water filter with care. Do NOT use excessive force when you reinsert the water filter so as NOT to damage the water filter mesh.

Water pressure relief valve

Open the valve and check if it operates correctly. The water may be very hot!

Checkpoints are:

▪ The water flow coming from the relief valve is high enough, no

blockage of the valve or in between piping is suspected.

▪ Dirty water coming out of the relief valve:

▪ open the valve until the discharged water does NOT contain dirt

anymore

▪ flush the system and install an additional water filter (a

magnetic cyclone filter is preferable).

It is recommended to do this maintenance more frequently.

Switch box

▪ Carry out a thorough visual inspection of the switchbox and look

for obvious defects such as loose connections or defective wiring. If applicable, also inspect the switchbox of the control box, option box, and backup heater.

▪ Using an ohmmeter, check if contactors K1M, K2M, and K5M in

the switchbox of the backup heater, and K3M in the switchbox of the control box (depending on your installation) operate correctly. All contacts of these contactors must be in open position when the power is turned OFF.

WARNING

If the internal wiring is damaged, it has to be replaced by the manufacturer, its service agent or similarly qualified persons.

Glycol concentration

If glycol was added to the system and a system refill is required, make sure the final concentration of glycol is according to the requirements set out in " To protect the water circuit against

freezing"on page35. Make sure the water quality complies with EU

directive 98/83 EC.

12 Troubleshooting

12.1 Overview: Troubleshooting

This chapter describes what you have to do in case of problems.

It contains information about:

▪ Solving problems based on symptoms

▪ Solving problems based on error codes

Before troubleshooting

Carry out a thorough visual inspection of the unit and look for obvious defects such as loose connections or defective wiring.

12.2 Precautions when troubleshooting

WARNING

▪ When carrying out an inspection on the switch box of

the unit, always make sure that the unit is disconnected from the mains. Turn off the respective circuit breaker.

▪ When a safety device was activated, stop the unit and

find out why the safety device was activated before resetting it. NEVER bridge safety devices or change their values to a value other than the factory default setting. If you are unable to find the cause of the problem, call your dealer.

DANGER: RISK OF ELECTROCUTION

WARNING

Prevent hazard due to the inadvertent resetting of the thermal cut-out: this appliance must NOT be supplied through an external switching device, such as a timer, or connected to a circuit that is regularly turned ON and OFF by the utility.

DANGER: RISK OF BURNING

12.3 Solving problems based on symptoms

12.3.1 Symptom: The unit is NOT heating or cooling as expected

Possible causes Corrective action

The temperature setting is NOT correct

Check the temperature setting on the remote controller. Refer to the operation manual.

Installer reference guide

Page 72

12 Troubleshooting

Possible causes Corrective action

The water flow is too low Check and make sure that:

▪ All shut-off valves of the water

circuit are completely open.

▪ The water filter is clean. Clean

if necessary.

▪ There is no air in the system.

Purge air if necessary. You can purge air manually (see

"To perform a manual air purge"on page67) or use the

automatic air purge function (see "To perform an automatic

air purge"on page67).

▪ The water pressure is >1 bar.

▪ The expansion vessel is NOT

broken.

▪ The resistance in the water

circuit is NOT too high for the pump (see the ESP curve in the "Technical data" chapter).

▪ The pump is NOT blocked. To

check this, perform a pump test (see "9.4.4 To perform an

actuator test run"on page68).

If it is blocked, the pump will perform a deblocking routine during this test. During the deblocking routine, the LED on the pump will blink red. From the moment the pump is deblocked, the LED will stay green. If the pump cannot be deblocked in 30 minutes, error 7H-05 will appear on the user interface. If this is the case, the pump needs to be checked and possibly replaced.

If the problem persists after you have conducted all of the above checks, contact your dealer. In some cases, it is normal that the unit decides to use a low water flow.

The water volume in the installation is too low

INFORMATION

If an error occurs during the deblocking routine, the deblocking routine will stop and error 7H‑05 will appear on the user interface (NOT the error that caused the deblocking routine to stop). To make this error appear, first accept the 7H‑05 error.

Make sure that the water volume in the installation is above the minimum required value (see

"6.3.3To check the water volume and flow rate"on page24).

12.3.2 Symptom: The compressor does NOT start

Possible causes Corrective action

The unit must start up out of its operation range (the water temperature is too low)

The preferential kWh rate power supply settings and electrical connections do NOT match

The preferential kWh rate signal was sent by the electricity company

If the system contains a backup heater:

If the water temperature is too low, the unit uses the backup heater to reach the minimum water temperature first (15°C).

Check and make sure that:

▪ The power supply to the

backup heater is correctly wired.

▪ The backup heater thermal

protector is NOT activated.

▪ The backup heater contactors

are NOT broken.

If the system does NOT contain a backup heater:

It may be required to start up with a small water volume. To do this, gradually open the heat emitters. As a result, the water temperature will gradually rise. Monitor the inlet water temperature ([6.1.6] in the menu structure) and make sure it does NOT drop below 15°C.

If the problem persists after you have conducted all of the above checks, contact your dealer.

This should match with the connections as explained in

"6.4Preparing electrical wiring"on page26 and "7.8.5To connect the main power supply"on page38.

Wait for the power to return (2 hours max.).

12.3.3 Symptom: The pump is making noise (cavitation)

Possible causes Corrective action

There is air in the system Purge air manually (see "To

perform a manual air purge"on page67) or use the automatic air

purge function (see "To perform

an automatic air purge"on page67).

The water pressure at the pump inlet is too low

Check and make sure that:

▪ The water pressure is >1bar.

▪ The manometer is not broken.

▪ The expansion vessel is NOT

broken.

▪ The pre-pressure setting of the

expansion vessel is correct (see "6.3.4 Changing the pre-

pressure of the expansion vessel"on page25).

▪ If the flow sensor detects flow when the pump is not

running, the unit will stop operation and the user interface will display error C0‑00. For the unit to resume operation, this error needs to be reset manually.

▪ If the flow switch detects flow when the pump is not

running, the unit will temporarily stop operation and the user interface will display error C0‑01. After some time, the error will reset automatically and the unit will resume operation. If the problem persists, the unit will stop operation and the user interface will display error C0‑02. For the unit to resume operation, this error needs to be reset manually.

13 Disposal

NOTICE

Do not try to dismantle the system yourself: the dismantling of the system, treatment of the refrigerant, oil and other parts must comply with applicable legislation. Units must be treated at a specialised treatment facility for reuse, recycling and recovery.

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

13.1 Overview: Disposal

Typical workflow

Disposing of the system typically consists of the following stages:

1 Pumping down the system.

2 Bringing the system to a specialized treatment facility.

INFORMATION

For more details, see the service manual.

13.2 To pump down

Example: To protect the environment, pump down when disposing

of the unit.

It is NOT required to pump down when relocating the unit.

DANGER: RISK OF EXPLOSION

Pump down – Refrigerant leakage. If you want to pump

down the system, and there is a leakage in the refrigerant circuit:

▪ Do NOT use the unit's automatic pump down function,

▪ Use a separate recovery system so that the unit's

compressor does NOT have to operate.

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 breakdown or damage to the system can result due to abnormal pressure in the refrigerant cycle.

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

A External static pressure B Water flow rate C Operation range

Notes:

▪ About the dashed lines: The operation area is extended to lower

flow rates only in case the unit operates with heat pump only, and the temperature of the flow medium is sufficiently high. (This does not apply to start-up operation, defrost operation, and backup heater operation in case a backup heater is installed.)

▪ The upper operation range is only valid if the flow medium is

water. If glycol is added to the system, the operation range limit is lower.

▪ Selecting a flow outside the operating area can damage the unit or

cause the unit to malfunction.
