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.

1.2.3 Refrigerant

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

1 General safety precautions

If Then

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.

1.2.4 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.

2 About the documentation

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.

▪ Setting up the energy metering

▪ Setting up the power consumption

▪ Setting up an external temperature sensor

5.2 Setting up the space heating system

The Daikin 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 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 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.5.1.2] to 1.

5.2.1 Single room

functionality can decrease or increase the desired leaving water temperature based on the actual room temperature (modulation). This results in:

▪ Stable room temperature matching the desired temperature

(higher comfort)

▪ Less ON/OFF cycles (more quiet, higher comfort and higher

efficiency)

▪ Lowest possible leaving water temperature (higher efficiency)

▪ Easy. You can easily set the desired room temperature via the

user interface:

▪ For your daily needs, you can use preset values and schedules.

▪ To deviate from your daily needs, you can temporarily overrule

the preset values and schedules, use the holiday mode…

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 or an external room thermostat), while the other rooms are controlled by so-called thermostatic valves, which open or close depending on the room temperature.

Setup

A Main leaving water temperature zone B One single room

a Remote controller of the heatpump convectors

▪ The underfloor heating or radiators are directly connected to the

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

the heatpump convectors.

▪ The space heating demand signal is sent to one digital input on

the indoor unit (X2M/1 and X2M/4).

INFORMATION

When using multiple heat pump convectors, make sure each one receives the infrared signal from the remote controller of the heatpump convectors.

▪ Integrate the auxiliary boiler as follows:

Benefits

▪ Comfort.

▪ The smart room thermostat functionality can decrease or

increase the desired leaving water temperature based on the actual room temperature (modulation).

▪ The combination of the two heat emitter systems provides the

excellent heating comfort of the under floor heating, and the rapid air heat up of the heat pump convectors (e.g., living room=under floor heating and the bedroom=convector (no continuous heating)).

▪ Efficiency.

▪ Depending on the demand, the indoor unit supplies different

leaving water temperature matching the design temperature of the different heat emitters.

▪ Underfloor heating has the best performance with Altherma LT.

5.4.2 Selecting the desired temperature for the DHW tank

People experience water as hot when its temperature is 40°C. Therefore, the DHW consumption is always expressed as equivalent hot water volume at 40°C. However, you can set the DHW tank temperature at a higher temperature (example: 53°C), which is then mixed with cold water (example: 15°C).

Selecting the volume and desired temperature for the DHW tank consists of:

1 Determining the DHW consumption (equivalent hot water

volume at 40°C).

2 Determining the volume and desired temperature for the DHW

tank.

Possible DHW tank volumes

Type Possible volumes

Integrated DHW tank ▪ 180l

Energy saving tips

▪ If the DHW consumption differs from day to day, you can program

a weekly schedule with different desired DHW tank temperatures for each day.

▪ The lower the desired DHW tank temperature, the more cost

effective.

▪ The heatpump itself can produce domestic hot water of maximum

55°C. The electrical resistance integrated in the heat pump can higher this temperature. However, this consumes more energy. Daikin recommends to set the desired DHW tank temperature below 55°C to avoid using the electrical resistance.

▪ When the heatpump produces domestic hot water, it cannot heat

up a space. When you need domestic hot water and space heating at the same, Daikin recommends to produce the domestic hot water during the night when there is lower space heating demand.

Determining the DHW consumption

Answer the following questions and calculate the DHW consumption (equivalent hot water volume at 40°C) using the typical water volumes:

Question Typical water volume

How many showers are needed

1shower=10min×10l/min=100l

per day?

How many baths are needed per

1bath=150l

day?

How much water is needed at the

1sink=2min×5l/min=10l

kitchen sink per day?

Are there any other domestic hot

—

water needs?

Example: If the DHW consumption of a family (4 persons) per day is as follows:

▪ 3 showers

▪ 1 bath

▪ 3 sink volumes

Then the DHW consumption = (3×100l)+(1×150l)+(3×10l)=480l

Determining the volume and desired temperature for the DHW tank

Formula Example

V1=V2+V2×(T2−40)/(40−T1) If:

▪ V2=180l

▪ T2=54°C

▪ T1=15°C

Then V1=280l

V2=V1×(40−T1)/(T2−T1) If:

▪ V1=480l

▪ T2=54°C

▪ T1=15°C

Then V2=307l

V1DHW consumption (equivalent hot water volume at 40°C) V2Required DHW tank volume if only heated once T2DHW tank temperature T1Cold water temperature

5.4.3 Setup and configuration – DHW tank

▪ For large DHW consumptions, you can heat up the DHW tank

several times during the day.

▪ To heat up the DHW tank to the desired DHW tank temperature,

you can use the following energy sources:

▪ Thermodynamic cycle of the heatpump

▪ Electrical backup heater

▪ Produced heat

▪ Consumed energy

▪ You can read out the energy data:

▪ For space heating

▪ For domestic hot water production

▪ You can read out the energy data:

▪ Per month

▪ Per year

INFORMATION

The calculated produced heat and consumed energy are an estimation, the accuracy cannot be guaranteed.

5.5.1 Produced heat

INFORMATION

The sensors used to calculate the produced heat are calibrated automatically.

▪ The produced heat is calculated internally based on:

▪ The leaving and entering water temperature

▪ The flow rate

▪ Setup and configuration: No additional equipment needed.

5.5.2 Consumed energy

Measuring the consumed energy

▪ Requires external power meters.

▪ Setup and configuration:

▪ For the specifications of each type of meter, see "14Technical

data"on page66.

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

kWh for each power meter via the user interface. Consumed energy data will only be available if this setting is configured.

INFORMATION

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

5.5.3 Normal kWh rate power supply

General rule

One power meter that covers the entire system is sufficient.

Setup

Connect the power meter to X5M/7 and X5M/8.

Power meter type

Use a three-phase power meter.

Example

A Indoor unit

a Electrical cabinet (L1/L2/L3/N) b Power meter (L1/L2/L3/N) c Fuse (L1/L2/L3/N) d Backup heater (L1/L2/L3/N) e Indoor unit (L1/L2/L3/N)

Exception

▪ You can use a second power meter if:

▪ The power range of one meter is insufficient.

▪ The electrical meter cannot easily be installed in the electrical

cabinet.

▪ Connection and setup:

▪ Connect the second power meter to X5M/9 and X5M/10.

▪ In the software the power consumption data of both meters is

added so you do NOT have to set which meter covers which power consumption. You only need to set the number of pulses of each power meter.

▪ See "5.5.4 Preferential kWh rate power supply" on page16 for

an example with two power meters.

5.5.4 Preferential kWh rate power supply

Setup

▪ Connect power meter1 to X5M/7 and X5M/8.

▪ Connect power meter2 to X5M/9 and X5M/10.

Refer to "6.4.3 Overview of electrical connections except external

actuators"on page22.

5.6 Setting up the power consumption control

▪ The power consumption control:

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

(sum of indoor unit and backup heater).

▪ 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

▪ During emergency operation, the power consumption

control will NOT be used. This is because the backup heater has a higher capacity then during normal operation (9 kW instead of 6 kW) and therefore the power calculated by the unit will be lower then the actual power.

▪ If power limitation is enabled, water temperature set

points above 60°C in space heating are NOT guaranteed.

5.6.1 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 and DHW production.

5.6.2 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. 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…).

the description of all settings, see "8Configuration"on page34):

▪ 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.

5.6.3 Power limitation process

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

1 Limits electrical heater.

2 Turn OFF the electrical heater.

3 Limits the compressor.

4 Turns OFF the compressor.

5.7 Setting up an external temperature sensor

Indoor ambient temperature

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

▪ 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: For installation instructions, see the installation manual of

the remote indoor sensor.

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

Outdoor ambient temperature

The remote outdoor sensor (delivered as accessory) measures the outdoor ambient temperature.

▪ Setup:

▪ To install the remote outdoor sensor outside, see the

installation manual of the sensor (delivered as accessory).

▪ To connect the remote outdoor sensor to the indoor unit, see

"7.6.7To connect the remote outdoor sensor"on page31.

▪ Configuration: None.

6.2 Preparing installation site

Do NOT install the unit in places often used as work place. In case of construction works (e.g. grinding works) where a lot of dust is created, the unit must be covered.

Choose the installation location with sufficient place for carrying the unit in and out of the site.

6.2.1 Installation site requirements of the indoor unit

INFORMATION

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

▪ Mind the following spacing installation guidelines:

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 from 5~30°C.

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 for brine circuit and space heating circuit. Using the system in an open water system will lead to excessive corrosion.

WARNING

When connecting to an open groundwater system, an intermediate heat exchanger is required to prevent damage (dirt, freeze ups) to the unit.

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

glycol to the space heating 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 piping diameter in relation to the

required flow and the available external static pressure of the pump. See "14Technical data"on page66 for the external static pressure curves of the indoor unit.

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

indoor unit operation in the following table. When the flow is lower, flow error 7H will be displayed and the indoor unit will be stopped.

Model Minimum flow during backup heater

operation

10 ▪ Space heating circuit: 12l/min

▪ Brine circuit: 25l/min

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

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

▪ Field supply components – Fluid pressure and temperature.

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

▪ Fluid pressure – Space heating and brine circuit. The

maximum fluid pressure of the space heating and brine circuit is 4bar. Provide adequate safeguards in the water circuit to ensure that the maximum pressure is NOT exceeded.

▪ Fluid pressure – Domestic hot water tank. The maximum fluid

pressure of the domestic hot water tank is 10 bar. Provide adequate safeguards in the water circuit to ensure that the maximum pressure is NOT exceeded.

▪ Fluid temperature. All installed piping and piping accessories

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

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

system in order to allow complete drainage of the circuit.

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

pressure relief valve to avoid fluid dripping out of the unit. See

"7.5.5 To connect the pressure relief valve to the drain" on page27.

WARNING

▪ All pipe work connected to the brine pressure relief

valve MUST have a continuous fall.

▪ The discharge pipe from the brine pressure relief valve

MUST terminate in a safe, visible position without forming any risk to persons in the vicinity.

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

must also be easily accessible for servicing. At the space heating side, 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 fluid circuit.

Because the unit's internal circuit uses copper piping, excessive corrosion may occur. Zn coated parts used in the brine circuit may lead to the precipitation of certain components in the anti-freeze fluids corrosion inhibitor.

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.

INFORMATION

Be aware of the hygroscopic property of anti-freeze fluids: it absorbs moisture from its environment. Leaving the cap off the anti-freeze fluid container causes the concentration of water to increase. The anti-freeze fluid concentration is then lower than assumed. And in consequence, freezing can happen after all.

Preventive actions MUST be taken to ensure minimal exposure of the anti-freeze fluid to air.

▪ 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 in the

space heating circuit, the maximum change-over time of the valve MUST be 60seconds.

▪ 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 "8.3.2Domestic hot

water control: advanced"on page46.

▪ 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.

▪ Recirculation pump. In accordance with the applicable

legislation, it may be required to connect a recirculation pump in between the hot water end point and the recirculation connection of the domestic hot water tank.

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)

6.3.3 To check the water volume and flow rate of the space heating circuit and brine circuit

The indoor unit has 2 expansion vessels of 10 litre, one for the space heating circuit and one for the brine circuit.

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.

▪ You must check the total space heating water volume unit.

▪ You must check the total brine water volume in the unit.

Minimum water volume

Check that the total water volume per circuit in the installation is minimum 20litre, the internal water volume of the indoor unit NOT included.

INFORMATION

If a minimum heating load of 1kW can be guaranteed and setting [9‑04] is changed by the installer from 1 to 4°C, the minimum water volume can be lowered to 10litre.

INFORMATION

In critical processes, or in rooms with a high heat load, extra water might be required.

NOTICE

When circulation in each space heating loop is controlled by remotely controlled valves, it is important that the minimum water volume is guaranteed, even if all of the valves are closed.

Maximum water volume

Use the following graphs to determine the maximum water volume for the calculated pre-pressure. For brine, this is dependent on the variation of brine temperature in the system. Example: throughout the year, the temperature of the brine can fluctuate between –7°C and 10°C, as in graph1, or between 0°C and 10°C as in graph2.

Graph1: Brine temperature fluctuation is 17°C

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).

Minimum required flow rate during backup heater operation

12l/min

See the recommended procedure as described in "9.4 Checklist

during commissioning"on page55.

6.3.4 Changing the pre-pressure of the expansion vessel

NOTICE

Only a licensed installer may 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 schräder valve of the expansion vessel.

6.3.5 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.

Example 2

The indoor unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 300l.

Actions:

▪ Because the total water volume (300 l) is more than the default

water volume (280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 350 l.

(See the graph in the chapter above).

▪ Because 300 l is lower than 350 l, the expansion vessel is

appropriate for the installation.

7.5 Connecting the water piping

7.5.1 About connecting the water piping

Before connecting the water piping

Make sure the indoor unit is mounted.

Typical workflow

Connecting the water piping typically consists of the following stages:

1 Connecting the water piping of the indoor unit.

2 Connecting the pressure relief valve to the drain.

3 Filling the space heating circuit.

4 Filling the domestic hot water tank.

5 Insulating the water piping.

6 Connecting the recirculation piping.

7 Connecting the drain hose.

7.5.2 Precautions when connecting the water piping

INFORMATION

Also read the precautions and requirements in the following chapters:

▪ General safety precautions

▪ Preparation

7.5.3 To connect the water piping

NOTICE

Do NOT use excessive force when connecting the piping. Deformation of the piping can cause malfunctioning of the unit.

1 Connect the domestic hot water in and out pipes to the indoor

unit.

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.

7.5.4 To connect the recirculation piping

Prerequisite: Only required if you need recirculation in your system.

1 Loosen and remove the screws at the bottom of the unit.

2 Slide the front panel of the unit downwards and remove it.

3 Loosen and remove the 4 screws that fix the top panel.

4 Remove the top panel from the unit.

b Space heating water in

d Domestic cold water in (cold water supply)

NOTICE

It is recommended to install shut-off valves to cold water in and hot water out connections. Shut-off valves are field supplied.

NOTICE

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

2 Connect the space heating in and out pipes to the indoor unit.

The blow out should be connected to an appropriate drain according to the applicable legislation. It is recommended to use a tundish.

WARNING

The discharge pipes from the pressure relief valves MUST terminate in a safe and visible position without forming any risk to persons in the vicinity.

7.5.6 To connect the drain hose

Condensate can form on the brine components inside the compressor department of the unit. The unit contains a drain pan. Depending on room ambient temperature, room humidity and operation condition, the drain pan can overflow. A drain hose is supplied with the unit.

The drain hose is routed to the backside on the left, close to the bottom of the unit. A field supplied drain pump might be needed to pump the water away to the field drain.

7.5.7 To fill the space heating circuit

1 Connect the water supply hose to the fill valve (field supply).

NOTICE

▪ Air in the water circuit can cause malfunctioning of the

backup heater. During filling, it may not be possible to remove all the air from the circuit. Remaining air will be removed through the automatic air purge valves during the initial operating hours of the system. Additional filling with water afterwards may be required.

▪ To purge the system, use the special function as

described in the chapter "9 Commissioning" on

page 55. This function should be used to purge the

heat exchanger coil of the domestic hot water tank.

6 Close the fill valve.

7 Disconnect the water supply hose from the fill valve.

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.

7.5.8 To fill the domestic hot water tank

1 Open every hot water tap in turn to purge air from the system

pipe work.

2 Open the cold water supply valve.

3 Close all water taps after all air is purged.

4 Check for water leaks.

5 Manually operate the field-installed pressure relief valve to

ensure a free water flow through the discharge pipe.

7.5.9 To insulate the water piping

The piping in the complete water circuit MUST be insulated to prevent reduction of the heating capacity.

2 Open the fill valve.

3 Make sure that the automatic air purge valve is open (at least 2

turns).

INFORMATION

For location of the air purge valve, see "Dimensions and service space: Indoor unit" in chapter "14 Technical

data"on page66.

General rule: the units freeze up prevention limit temperature MUST be 10°C lower than the minimum possible brine inlet temperature for the unit.

Example: When the minimum possible brine inlet temperature in a certain application is 0°C, then the unit freeze up prevention limit temperature MUST be set to –10°C or lower. Result will be that the brine mixture may NOT freeze above that temperature. To prevent freezing of the unit, check the type and concentration of the brine carefully.

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, heat pump convector, under floor loops) or situation, it can be possible to change the difference between entering and leaving water temperature.

Leaving water temperature: Modulation

Only applicable in case of room thermostat control. When using the room thermostat functionality, the customer needs to set the desired room temperature. The unit will supply hot water to the heat emitters and the room will be heated. Additionally, also the desired leaving water temperature must be configured: when turning on the 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)

[A.3.1.1.5] [8-05] Modulated LWT:

▪ 0 (No) (default): disabled.

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

▪ 1 (Yes): 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

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, this compensation can be selected (see illustration below). Use this setting to compensate for possible heat losses of the building when the outdoor temperature is around 0°C (e.g. in cold region countries).

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).

Installer reference guide

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.

temperature home page is OFF, and the outdoor ambient temperature drops below 4°C, then the unit will supply leaving water to the heat emitters to heat up the room again, and the leaving water temperature setpoint will be lowered by 5°C.

▪ When the leaving water

temperature home page is ON, the outdoor ambient temperature drops below 4°C, then the unit will supply leaving water to the heat emitters to heat up the room again, and the leaving water temperature setpoint will be lowered by 5°C.

Under leaving water temperature control, room frost protection is NOT guaranteed. However, if [2‑06] is set to "1", limited frost protection by the unit is possible:

▪ When the leaving water temperature home page is OFF and the

outdoor ambient temperature drops below 4°C, then the unit will supply leaving water to the heat emitters to heat up the room again, and the leaving water temperature setpoint will be lowered by 5°C.

▪ When the leaving water temperature home page is ON, then the

unit will supply leaving water to the heat emitters to heat up the room according to normal logic.

NOTICE

For the (limited) frost protection to be possible, auto emergency MUST be set to Automatic ([A.5.1.2]=1).

Shut-off valve

INFORMATION

If the storage temperature set point is higher than 55°C, Daikin recommends NOT to disable the backup heater second step because it will have a big impact on the required time for the unit to heat up the domestic hot water tank.

Auto emergency

When the heat pump fails to operate the backup heater can serve as an emergency heater and either automatically or non-automatically 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 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 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 that setting [A.5.1.2] Emergency shall be set to Automatic.

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 an air purge on the brine circuit.

4 Performing a test run for the system.

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

6 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:

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

The indoor unit is properly mounted.

The following field wiring has been carried out according to this document and the applicable legislation:

▪ Between the local supply panel and the indoor unit

▪ Between the indoor unit and the valves (if applicable)

▪ Between the indoor unit and the room thermostat (if

applicable)

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 indoor unit.

There are NO refrigerant leaks.

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

There is NO water and/or brine leak inside the indoor unit.

There are no odour traces noticeable of the used brine.

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

The pressure relief valves purge to a safe location when opened.

The minimum water volume is guaranteed in all conditions. See "To check the water volume and flow rate of the space heating circuit and brine circuit" in

"6.3Preparing piping"on page18.

9.4 Checklist during commissioning

The minimum flow rate during backup heater/defrost operation is guaranteed in all conditions. See "To check the water volume and flow rate of the space heating circuit and brine circuit" in "6.3Preparing piping"on page18.

To perform an air purge.

To perform an air purge on the brine circuit.

To perform a test run.

To perform an actuator test run.

Underfloor screed dryout function

The underfloor screed dryout function is started (if necessary).

9.4.1 To check the minimum flow rate

1 Confirm according to the hydraulic configuration which space

heating loops can be closed due to mechanical, electronic, or other valves.

2 Close all space heating loops that can be closed (see previous

step).

3 Start the pump test run operation (see "9.4.5 To perform an

actuator test run"on page58).

4 Go to [6.1.8]: > Information > Sensor information > Flow rate

to check the flow rate. During pump test run operation, the unit can operate below this minimum required flow rate that is needed during defrost/backup heater operation.

Bypass valve foreseen?

Yes No

Modify the bypass valve setting to reach the minimum required flow rate + 2l/min

Minimum required flow rate during backup heater operation

12l/min

9.4.2 Air purge function on the space heating circuit

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 remove of air in the water circuit will start.

In case the actual flow rate is below the minimum flow rate (required during defrost/backup heater operation), modifications at hydraulic configuration are required. Increase the space heating loops that can NOT be closed or install a pressure controlled bypass valve.

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 to purge 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 space heating or domestic hot water heating mode. The operation speed of the pump (slow or quick) can also be set.

▪ Automatic: the unit change automatically the pump speed and the

position of the 3-way valve between space heating or domestic hot water heating mode.

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.

automatic air purge function (see "To perform an automatic

air purge"on page56).

▪ 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.

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.

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 of the space heating circuit and brine circuit"on page20).

12.3.2 Symptom: The compressor does NOT start (space heating or domestic water heating)

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 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 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22 and "7.6.6To connect the main power supply"on page30.

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56) or use the automatic air

purge function (see "To perform

an automatic air purge"on page56).

The pressure at the pump inlet is too low

Check and make sure that:

▪ The 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21).

12.3.4 Symptom: The pressure relief valve opens

Installer reference guide

Possible causes Corrective action

The expansion vessel is broken Replace the expansion vessel.

The water or brine volume in the installation is too high

Make sure that the water or brine volume in the installation is below the maximum allowed value (see

"6.3.3To check the water volume and flow rate of the space heating circuit and brine circuit"on page20 and "6.3.4Changing the pre-pressure of the expansion vessel"on page21).

4P351748-1C – 2015.10

Page 63

12 Troubleshooting

Possible causes Corrective action

The water circuit head is too high The water circuit head is the

difference in height between the unit and the highest point of the water circuit. If the unit is located at the highest point of the installation, the installation height is considered 0m. The maximum water circuit head is 10m.

Check the installation requirements.

12.3.5 Symptom: The pressure relief valve leaks

Possible causes Corrective action

Dirt is blocking the water pressure relief valve outlet

Check whether the pressure relief valve works correctly by turning the red knob on the valve counterclockwise:

▪ If you do NOT hear a clacking

sound, contact your dealer.

▪ If the water or brine keeps

running out of the unit, close both inlet and outlet shut-off valves first and then contact your dealer.

12.3.6 Symptom: The space is NOT sufficiently heated at low outdoor temperatures

Possible causes Corrective action

The backup heater operation is not activated

The backup heater equilibrium temperature has not been configured correctly

Check and make sure that:

▪ The backup heater operation

mode is enabled. Go to:

▪ [A.5.1.1] > Installer settings

> Heat sources > Backup heater > Operation mode OR

▪ [A.8] > Installer settings >

Overview settings [4‑00]

▪ The thermal protector of the

backup heater has not been activated. If it has, check:

▪ The space heating and brine

circuit pressure

▪ Whether there is air in the

system

▪ The air purge operation

Press the reset button in the switch box. See

"14.3Components"on page69

for the location of the reset button.

Increase the "equilibrium temperature" to activate the backup heater operation at a higher outdoor temperature. Go to:

▪ [A.5.1.4] > Installer settings >

Heat sources > Backup heater > Equilibrium temp. OR

▪ [A.8] > Installer settings >

Overview settings [5‑01]

12.3.7 Symptom: The pressure at the tapping point is temporarily unusual high

Possible causes Corrective action

Failing or blocked pressure relief valve.

▪ Flush and clean the complete

tank including the piping between pressure relief valve and the cold water inlet.

▪ Replace the pressure relief

valve.

12.3.8 Symptom: Decoration panels are pushed away due to a swollen tank

Possible causes Corrective action

Failing or blocked pressure relief valve.

Contact your local dealer.

12.3.9 Symptom: Tank disinfection function is NOT completed correctly (AH-error)

Possible causes Corrective action

The disinfection function was interrupted by domestic hot water tapping

Large domestic hot water tapping happened recently before the programmed start-up of the disinfection function

The disinfection operation was stopped manually: with the user interface displaying the DHW home page and its user permission level set to Installer, the button was pressed during disinfection operation.

Program the start-up of the disinfection function when the coming 4hours NO domestic hot water tapping is expected.

When the Domestic hot water > Type > Reheat or Reheat + sched. is selected, it is recommended to program the start-up 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.

Do NOT press the button while the disinfection function is active.

12.4 Solving problems based on error codes

When a problem happens, an error code appears on the user interface. It is important to understand the problem and to take countermeasure before resetting the error code. This should be done by a licensed installer or by your local dealer.

This chapter gives you an overview of all error codes and the content of the error code as it appears on the user interface.

For a more detailed troubleshooting guideline for each error, please see the service manual.

(c)

A Entering brine temperature B Leaving condenser water temperature

Remark: By default settings, the unit will allow operation with

entering brine temperatures to –5°C. As a result, the brine freezing temperature may not be higher than –15°C. For water – ethanol mixtures this corresponds to 29% ethanol (by mass), for water – propylene glycol mixtures this corresponds to 40% propylene glycol (by volume).

If the freezing temperature of the medium is higher than –15°C, then protection level of unit MUST be increased by field setting.

Refer to the installation manual and/or installer reference guide for instructions how to set a different freeze temperature of the medium (Tf) in the controller.

The unit will NOT operate at an entering brine temperature lower than Tf+10K.

Installer reference guide

Only backup heater operation if the set point is <24°C. Heat pump operation (assisted by backup heater if capacity shortage) Heat pump + backup heater operation Protect against freezing by adding anti-freeze to brine side. See also remark.
