4P569820-1A – 2019.09

1 General safety precautions

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 recharge is required, see 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.

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.

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

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.

CAUTION

When connecting the power supply, the earth connection must be made before the current-carrying connections are established. When disconnecting the power supply, the current-carrying connections must be separated before the earth connection is. The length of the conductors between the power supply stress relief and the terminal block itself must be as such that the current-carrying wires are tautened before the earth wire is in case the power supply is pulled loose from the stress relief.

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 above.

▪ 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.

▪ Setting up the brine low pressure switch

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 heatpump system?

Installer reference guide

EGSAH/X06+10DA9W(G)

Daikin Altherma 3 GEO

4P569820-1A – 2019.09

5 Application guidelines

▪ 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, we recommend 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 [C.2] Space heating/cooling 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.

NOTICE

An overpressure bypass valve can be integrated in the system. Keep in mind that this valve might not be shown on the illustrations.

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.

Underfloor heating or radiators – Thermostatic valves

If you are heating up rooms with underfloor 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 dedicated Human Comfort Interface (BRC1HHDA) 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.

INFORMATION

Mind situations where the main room can be heated by another heating source. Example: Fireplaces.

5.2.3 Multiple rooms – TwoLWT zones

If the heat emitters selected for each room are designed for different leaving water temperatures, you can use different leaving water temperature zones (maximum 2).

In this document:

▪ Main zone = Zone with the lowest design temperature in heating,

and the highest design temperature in cooling

▪ Additional zone = Zone with the highest design temperature in

heating, and the lowest design temperature in cooling.

CAUTION

If there is more than one leaving water zone, ALWAYS install a mixing valve station in the main zone to decrease (in heating) the leaving water temperature when the additional zone has demand.

Typical example:

5.3 Setting up an auxiliary heat source for space heating

▪ Space heating can be done by:

▪ The indoor unit

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

▪ When the room thermostat requests heating, the indoor 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 indoor unit is turned OFF.

▪ Bivalent operation is only possible for space heating, NOT for

domestic hot water production. Domestic hot water is always produced by the DHW tank connected to the indoor unit.

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.

Setup

▪ Integrate the auxiliary boiler as follows:

b Hot water OUT

c Remote outdoor sensor

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

1 Determining the DHW consumption (equivalent hot water

volume at 40°C).

2 Determining the desired temperature for the DHW tank.

Determining the DHW consumption

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

Question Typical water volume

How many showers are needed per day?

How many baths are needed per day?

How much water is needed at the kitchen sink per day?

Are there any other domestic hot water needs?

1shower = 10min×10l/min = 100l

1bath = 150l

1sink = 2min×5l/min = 10l

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

INFORMATION

DHW tank volume. You cannot select the volume of the

DHW tank because only one size is available.

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 (backup heater) integrated in the heat pump can increase this temperature. However, this consumes more energy. We recommend 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. In case you need domestic hot water and space heating at the same, we recommend to produce the domestic hot water during the night when there is lower space heating demand.

#2: Dual cable power supply (=split power supply)

X5M/5+6

INFORMATION

You cannot combine calculating the consumed energy (example: for the backup heater) and measuring the consumed energy (example: for the rest of the unit). If you do so, the energy data will be invalid.

Calculating the consumed energy

▪ The consumed energy is calculated internally based on:

▪ The actual power input of the indoor unit

▪ The set capacity of the backup heater

▪ The voltage

▪ Setup and configuration: None.

Measuring the consumed energy

▪ Preferred method because of higher accuracy.

▪ Requires external power meters.

▪ Setup and configuration: 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.

▪ Select continuous limitation mode

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

▪ Set the desired power limitation level

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 (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…).

Configuration

▪ Set the power consumption control settings in [9.9] via the user

interface (for the description of all settings, see

"10Configuration"[455]):

▪ Select limitation 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 the backup heater.

2 Turns OFF the backup heater.

3 Limits the compressor.

4 Turns OFF the compressor.

Example

If the power limitation level does NOT allow operation of full backup heater capacity, then power consumption is limited as follows:

A Indoor unit B Energy management system

a Power limitation activation (4 digital inputs)

b Backup heater

PiPower input

t Time

DI Digital inputs (power limitation levels)

a Power limitation active

b Actual power input

Setup

▪ Demand PCB (option EKRP1AHTA) needed.

▪ 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.

NOTICE

Disconnected sensor. If you use current limitation by

current sensors and one of the sensors is disconnected, the corresponding phase is not limited anymore.

Current sensors can be used to limit the consumption of the heat pump on every phase taking into account the set household fuse and the actual consumption of other appliances.

Current sensors must be installed before the main fuses on each phase to make use of this feature. This function can be useful in countries where the government gives incentives to limit the fuse sizes.

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. We recommend to use an external temperature sensor in the following cases:

▪ In room thermostat control, the dedicated Human Comfort

Interface (BRC1HHDA) is used as room thermostat and it measures the indoor ambient temperature. Therefore, the dedicated Human Comfort 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, we recommend to connect a remote indoor

sensor (option KRCS01-1).

▪ Setup and configuration:

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.

▪ Circuit types. Except for the refrigerant circuit, inside the unit 2

other circuits are included. For future references: the circuit connected to the bore hole is referred to as the brine circuit, the other circuit connected to the heating emitters is referred to as the space heating circuit.

▪ 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 from 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.

▪ Expansion vessel – Water side. To avoid cavitation, install an

expansion vessel (field supply) on the entering pipe before the water pump within 10m of 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 "16 Technical data" [4 98] for the external static pressure curves of the indoor unit.

▪ Fluid flow. Depending on the type of operation, the minimum

required flow can be different. See "7.1.3 To check the water

volume and flow rate of the space heating circuit and brine circuit"[429] for more information.

▪ 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 3bar.

▪ 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:

INFORMATION

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

▪ 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. Connect the drain hose

properly to the drain to avoid water dripping out of the unit. See

"6.3.4To connect the drain hose to the drain"[427].

▪ 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.

▪ 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.

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

vessel.

▪ You must check the total space heating water volume in the 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 [4.B] Space heating/cooling > Overshoot (overview field setting [9‑04]) is 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/cooling 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.

INFORMATION

Some types of preferential kWh rate power supply require a separate normal kWh rate power supply to the indoor unit. This is required in the following cases:

▪ if the preferential kWh rate power supply is interrupted

when active, OR

▪ if no power consumption of the indoor unit is allowed at

the preferential kWh rate power supply when active.

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.

The indoor unit is designed to receive an input signal by which the unit switches into forced off mode. At that moment, the unit compressor will not operate.

The wiring to the unit is different depending on whether the power supply is interrupted or not.

INFORMATION

▪ For an overview of the possible system layouts, see

"9.1.1System layout"[444]. For more information about

the electrical wiring, see "9.2.1 Overview of electrical

connections"[445].

INFORMATION

Before installation, confirm that the solar inverter/energy management system is equipped with the digital outputs required to connect it to the LAN adapter. For more information, see "9.5Smart Grid application"[451].

Connector X1A is for the connection of the LAN adapter to the digital outputs of a solar inverter/energy management system, and allows for the integration of the Daikin Altherma system in a Smart Grid application.

X1A/N+L supply a 230VAC detection voltage to the input contact of X1A. The 230V AC detection voltage enables the detection of the state (open or close) of the digital inputs and does NOT supply power to the rest of the LAN adapter PCB.

Make sure X1A/N+L are protected by a fast acting circuit breaker (rated current 100mA~6A, type B).

The rest of the wiring to X1A differs depending on the digital outputs available on the solar inverter/energy management system and/or on the Smart Grid operation modes that you want the system to run in. For more information, see "9.5Smart Grid application"[451].

To connect the solar inverter/energy management system

NOTICE

INFORMATION

Mind the polarity of the cable. The positive wire MUST be connected to X2A/1; the negative wire to X2A/2.

WARNING

Make sure to connect the electricity meter in the correct direction, so that it measures the total energy injected INTO the grid.

INFORMATION

How the solar inverter/energy management system is connected to X1A depends on the Smart Grid application. The connection described in the instructions below is for the system to run in the "Recommended ON" operation mode. For more information, see "9.5 Smart Grid

application"[451].

WARNING

Make sure X1A/N+L are protected by a fast acting circuit breaker (rated current 100mA~6A, type B).

WARNING

When connecting the wiring to LAN adapter terminal X1A, make sure each wire is securely fastened to the appropriate terminal. Use a screwdriver to open the wire clamps. Make sure the bare copper wire is fully inserted into the terminal (bare copper wire CANNOT be visible).

Normally, the LAN adapter applies network settings automatically, and no changes to these are required. If required, however, it is possible to configure network settings as follows:

▪ Via the configuration web interface (various settings);

▪ Via the DIP switch (custom static IP address only).

Note on the LAN adapter IP address

Assign an IP address to the LAN adapter in one of the following ways:

IP address Description + method

DHCP protocol (default) The system automatically

assigns the LAN adapter an IP address by way of the DHCP protocol. This is the default situation, and set on the configuration web interface. See

"Via the configuration web interface"[451].

Static IP address Bypass the DHCP protocol and

manually assign a static IP address to the LAN adapter. Do this via the configuration web interface. See "Via the

configuration web interface"[451].

Custom static IP address Bypass any IP settings made on

the configuration web interface and assign a custom static IP address to the LAN adapter. Do this via the DIP switch. See "Via

the DIP switch"[451].

INFORMATION

Normally, network/IP settings are automatically applied and require no changes. Only make changes to the network/IP settings when absolutely required (e.g. when the system does not detect the LAN adapter automatically).

To configure network settings

Via the configuration web interface

1 Go to "Network settings" on the configuration web interface.

2 Configure network settings.

INFORMATION

By default "DHCP active" is set to "Automatic" and IP settings are configured automatically and dynamically by way of the DHCP protocol. When setting "DHCP active" to "Manually", you bypass the DHCP protocol. Instead, define a static IP address for the LAN adapter in the fields next to "Static IP address".

When you set a static IP address for the LAN adapter, you make access to the configuration web interface via the URL (http://altherma.local) impossible. Therefore, when setting a static IP address, note it down somewhere, this for easy future access to the configuration web interface.

Via the DIP switch

The DIP switch allows you to assign a custom static IP address to the LAN adapter. This IP address is "169.254.10.10". When you choose to do this, you bypass any IP settings made on the configuration web interface.

To assign the custom static IP address to the LAN adapter:

1 Turn OFF the power to the LAN adapter.

2 Set DIP switch 2 to "ON".

3 Turn ON the power.

NOTICE

Use appropriate tooling to set the DIP switches to another position. Beware of electrostatic discharge.

9.5 Smart Grid application

INFORMATION

To use the LAN adapter for the Smart Grid application, it is required that DIP switch 1 is set to "OFF" (default the case). Alternatively, to disable the possibility of using the LAN adapter for the Smart Grid application, it is possible to set DIP switch 1 to "ON".

NOTICE

Use appropriate tooling to set the DIP switches to another position. Beware of electrostatic discharge.

The LAN adapter allows for the connection of the Daikin Altherma system to a solar inverter/energy management system, and enables it to run in various Smart Grid operation modes. In this way, all system components work together to limit the injection of (selfgenerated) power into the grid, instead converting this power into thermal energy by making use of the thermal storage capacity of the heat pump. This is called "energy buffering".

The system can buffer energy in the following ways:

▪ Heat up the domestic hot water tank

▪ Heat up the room

▪ Cool down the room

The Smart Grid application is controlled by the solar inverter/energy management system, that monitors the grid, and sends commands to the LAN adapter. The adapter is connected to the solar inverter/ energy management system (digital outputs) by way of connector X1A (digital inputs).

Solar inverter/energy management system

(digital outputs)

Digital output 1 SG0

Digital output 2 SG1

The solar inverter/energy management system controls the state of the digital inputs of the LAN adapter. Depending on the state of the inputs (open or closed), the Daikin Altherma system can run in the following Smart Grid operation modes:

Smart Grid operation mode SG0

(X1A/1+2)

Normal operation/Free running

Open Open

NO Smart Grid application

Recommended ON

Closed Open

Energy buffering in the domestic hot water tank and/or the room, WITH power limitation.

Forced OFF

Open Closed

Deactivation of unit and electrical heater operation in case of high energy tariffs.

Forced ON

Closed Closed

Energy buffering in the domestic hot water tank and/or the room, WITHOUT power limitation.

INFORMATION

For the system to run in all 4 possible Smart Grid operation modes, the solar inverter/energy management system needs to have 2 digital outputs available. If only 1 output is available, then you can only connect to SG0, and the system can only run in the "Normal operation/Free running" and "Recommended ON" operation modes. For the system to run in "Forced OFF" and "Forced ON", a connection to SG1 is required (for those operation modes, SG1 needs to get "closed").

INFORMATION

In case the system layout includes a controllable wall socket, and the solar inverter/energy management system activates this socket, SG0 gets "closed" and the system runs in the "Recommended ON" operation mode. If the solar inverter/energy management system deactivates the socket, SG0 (and SG1) get "opened" and the system runs in the "Normal operation/Free running" operation mode (due to the 230VC detection voltage to X1A/L+N getting cut off).

Energy buffering

Depending on Smart Grid settings (configuration web interface), energy buffering either happens in the domestic hot water tank only, or in the domestic hot water tank and in the room. You can choose whether or not to have the electrical heaters assist with the buffering of energy in the domestic hot water tank.

INFORMATION

▪ The system will ONLY buffer energy when the indoor

unit is in standby mode. Normal operation (scheduled actions, etc.) has priority over energy buffering.

▪ On the configuration web interface, the buffering is

default set to "domestic hot water tank only".

▪ The maximum temperature during domestic hot water

tank buffering is the maximum tank temperature for the applicable tank type.

▪ The space heating/cooling setpoint during room

buffering is the comfort setpoint for the room.

Power limitation

In the "Recommended ON" operation mode, the power consumption of the Daikin Altherma system is limited either statically or dynamically. In both cases, it is possible to include the power consumption of the electrical heaters in the calculation (default NOT the case).

IF THEN

Static power limitation

(Static power limitation)

Dynamic power limitation

(Pulse meter setting)

INFORMATION

When using an electricity meter for dynamic power limitation, it is recommended to set it to 100 pulse/kWh or 1000 pulse/kWh (i.e. Pulse meter setting on the configuration web interface).

INFORMATION

▪ In the "Forced ON" operation mode, energy buffering

happens WITHOUT power limitation.

▪ To get the most out of the energy buffering it is

recommended to make use of dynamic power limitation by way of an electricity meter.

▪ The electrical heaters will ONLY operate when the

power limitation is higher than the power rating of the heaters.

WARNING

Make sure to connect the electricity meter in the correct direction, so that it measures the total energy injected INTO the grid.

The power consumption of the indoor unit is limited statically based on a fixed value (default

1.5kW) that is set in the configuration web interface. During energy buffering, the power consumption of the indoor unit will NOT exceed this limit.

The value for this setting is only used if the system does not include an electricity meter (on the configuration web interface: Pulse meter setting: "No meter"). Otherwise, make use of dynamic power limitation.

The power limitation is autoadaptive, and dynamically performed based on the power injection into the grid, measured by the electricity meter. To minimise the power injection into the grid, the indoor unit operates as much as possible.

INFORMATION

▪ For dynamic power limitation to be possible, a single

connection point to the grid is required (one connection point for the photovoltaic system AND the domestic appliances). To function properly, the Smart Grid algorithm requires the net sum of generated AND consumed energy. The algorithm will NOT work when there are separate meters for generated energy and consumed energy.

▪ Since dynamic power limitation is performed based on

electricity meter input, you do NOT have to set the power limitation value in the configuration web interface.

9.5.2 Operation modes

"Normal operation/Free running" mode

In the "Normal operation"/"Free running" operation mode, the indoor unit operates as normal, according to its owner's settings and schedules. No Smart Grid functionalities are enabled.

"Recommended ON" mode

In the "Recommended ON" operation mode, the Daikin Altherma system makes use of solar/grid power (when it is available, as measured by the solar inverter/energy management system) to produce domestic hot water and/or heat up or cool down the space. The amount of solar/grid power that is used for buffering depends on the domestic hot water tank and/or the room temperature. To align solar/grid capacity and the power consumption by the Daikin Altherma system, the power consumption of the indoor unit is limited either statically (by a fixed value set in the configuration web interface) or dynamically (auto-adaptively, as measured by the electricity meter – if part of the system layout).

"Forced OFF" mode

In the "Forced OFF" operation mode, the solar inverter/energy management system triggers the system to deactivate the operation of the unit’s compressor and the electrical heaters. This is especially useful in case of energy management systems that react to high energy tariffs, or in case of grid overload (signaled by the energy distributor to the energy management system). Once active, "Forced OFF" mode will cause the system to stop space heating/cooling, as well as domestic hot water production.

INFORMATION

Once running in one of the Smart Grid operation modes, the system will keep running in that mode until the input state of the LAN adapter is changed. Beware that if the system runs in "Forced OFF" mode for a long time, comfort issues can occur.

"Forced ON" mode

In the "Forced ON" operation mode, the Daikin Altherma system makes use of solar/grid power (when it is available, as measured by the solar inverter/energy management system) to produce domestic hot water and/or heat up or cool down the space. The amount of solar/grid power that is used for buffering depends on the domestic hot water tank and/or the room temperature. In contrast to the "Recommended ON" operation mode, there is NO power limitation: the system selects the comfort setpoint for space heating/cooling, and will heat up the domestic hot water tank to the maximum temperature. The unit’s compressor and the electrical heaters are not limited in their power consumption.

The "Forced ON" operation mode is particularly useful in case of energy management systems that react to low energy tariffs, in case of grid overload (signaled by the energy distributor to the energy management system), or when multiple houses are connected to the grid that are controlled simultaneously, this to stabilise the grid.

10.4 Weather-dependent curve

10.4.1 What is a weather-dependent curve?

Weather-dependent operation

The unit operates 'weather dependent' if the desired leaving water or tank temperature is determined automatically by the outdoor temperature. It therefore is connected to a temperature sensor on the North wall of the building. If the outdoor temperature drops or rises, the unit compensates instantly. Thus, the unit does not have to wait for feedback by the thermostat to increase or decrease the temperature of the leaving water or tank. Because it reacts more quickly, it prevents high rises and drops of the indoor temperature and water temperature at tap points.

Advantage

Weather-dependent operation reduces energy consumption.

Weather-dependent curve

To be able to compensate for differences in temperature, the unit relies on its weather-dependent curve. This curve defines how much the temperature of the tank or leaving water must be at different outdoor temperatures. Because the slope of the curve depends on local circumstances such as climate and the insulation of the house, the curve can be adjusted by an installer or user.

Types of weather-dependent curve

There are two types of weather-dependent curves:

▪ 2-points curve

▪ Slope-offset curve

Which type of curve you use to make adjustments, depends on your personal preference. See "10.4.4 Using weather-dependent

curves"[462].

Availability

The weather-dependent curve is available for:

▪ Main zone - Heating

▪ Main zone - Cooling

▪ Additional zone - Heating

▪ Additional zone - Cooling

▪ Tank

INFORMATION

To operate weather dependent, correctly configure the setpoint of the main zone, additional zone or tank. See

"10.4.4Using weather-dependent curves"[462].

10.4.2 2-points curve

Define the weather-dependent curve with these two setpoints:

▪ Setpoint (X1, Y2)

▪ Setpoint (X2, Y1)

Example

10.4.3 Slope-offset curve

Slope and offset

Define the weather-dependent curve by its slope and offset:

▪ Change the slope to differently increase or decrease the

temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is in general fine but at low ambient temperatures too cold, raise the slope so that leaving water temperature is heated increasingly more at decreasingly lower ambient temperatures.

▪ Change the offset to equally increase or decrease the

temperature of the leaving water for different ambient temperatures. For example, if leaving water temperature is always a bit too cold at different ambient temperatures, shift the offset up to equally increase the leaving water temperature for all ambient temperatures.

Examples

Weather-dependent curve when slope is selected:

Emitter type

Depending on the system water volume and the heater emitter type of the main zone, heating up or cooling down the main zone can take longer. The setting Emitter type can compensate for a slow or a quick heating/cooling system during the heat up/cool down cycle. The target delta T for the main zone depends on this setting.

In room thermostat control, Emitter type influences 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.

It is important to set Emitter type correctly and in accordance with your system layout.

The setting of the emitter type has an influence on the space heating setpoint range and the target delta T in heating as follows:

Emitter type Main

zone

0: Underfloor heating

1: Fancoil unit Maximum 65°C Variable (see [2.B])

2: Radiator Maximum 65°C Variable (see [2.B])

NOTICE

The maximum setpoint in space heating depends on the emitter type as can be seen in above table. If there are 2 water temperature zones, then the maximum setpoint is the maximum of the 2 zones.

CAUTION

If there are 2 zones, it is important that the zone with the lowest water temperature is configured as the main zone, and the zone with the highest water temperature is configured as the additional zone. Not configuring the system in this way could cause damage to the heat emitters.

CAUTION

If there are 2 zones and the emitter types are wrongly configured, water of high temperature can be sent towards a low temperature emitter (underfloor heating). To avoid this:

▪ Install an aquastat/thermostatic valve to avoid too high

temperatures towards a low temperature emitter.

▪ Make sure you set the emitter types for the main zone

[2.7] and for the additional zone [3.7] correctly in accordance with the connected emitter.

INFORMATION

Depending on the target delta T, the average emitter temperature will vary. To counteract the effect on the average emitter temperature due to a higher delta T target, the leaving water setpoint (fixed or weather dependent) can be adjusted.

Setpoint range

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

NOTICE

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

▪ maximum leaving water temperature at heating

operation according to the specifications of the floor heating installation.

▪ the minimum leaving water temperature at cooling

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

Space heating setpoint range

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).

▪ 2: 2 contacts: The used external

room thermostat can send a separate heating/cooling thermo ON/OFF condition. The room thermostat is connected to 2 digital inputs (X2M/35 and X2M/34). Select this value in case of a connection to the wired (EKRTWA) or wireless (EKRTR1) room thermostat

Leaving water temperature: Delta T

The target delta T in heating for the main zone depends on the emitter type for the main zone selected above. In heating, this setting indicates the temperature difference between the leaving water setpoint and entering water. In cooling, this setting indicates the temperature difference between entering and leaving water temperature.

The unit is designed to support underfloor loops operation. The recommended leaving water temperature for underfloor loops is 35°C. In such case, the unit will be controlled to realize a temperature difference of 5°C which means that the unit entering water temperature is around 30°C. Depending on the installed application (radiators, heat pump convector, underfloor 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 delta T. In some special cases, the measured deltaT can be different from the set value.

INFORMATION

In heating, the target delta T will only be achieved after some operation time, when the setpoint is being reached, because of the big difference between leaving water temperature setpoint and inlet temperature at startup.

INFORMATION

If the main zone or the additional zone has a heating demand, and this zone is equipped with radiators, then the target delta T that the unit will use in heating operation will be equal to the temperature set in [2.B].

If the zones are not equipped with radiators, then in heating the unit will give priority to the target deltaT for the additional zone, if there is a heating demand in the additional zone.

In cooling the unit will give priority to the target deltaT for the additional zone, if there is a cooling demand in the additional zone.

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)

# Code Description

[2.C.1] [8‑05] Modulation:

▪ 0 No: Disabled, 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.

[2.C.2] [8‑06] Max modulation:

▪ 0°C~10°C

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

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. See the illustration below.

10 Configuration

Exception: If the system is configured in room thermostat control with one leaving water temperature zone and quick heat emitters, the operation mode will change based on:

▪ The 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 mode is 22°C and in cooling mode it is 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 (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.

Emergency

When the heat pump fails to operate, the backup heater can serve as an emergency heater. It then takes over the heat load either automatically or by manual interaction.

▪ When Emergency is set to Automatic and a heat pump failure

occurs, the backup heater automatically takes over the domestic hot water production and space heating.

▪ When Emergency is set to Manual and a heat pump failure

occurs, the domestic hot water heating and space heating stops. To manually recover it via the user interface, go to the Malfunctioning main menu screen and confirm whether the backup heater can take over the heat load or not.

▪ Alternatively, when Emergency is set to:

▪ auto SH reduced/DHW on, space heating is reduced but

domestic hot water is still available.

▪ auto SH reduced/DHW off, space heating is reduced and

domestic hot water is NOT available.

▪ auto SH normal/DHW off, space heating operates as

normally but domestic hot water is NOT available. Similarly as in Manual mode, the unit can take the full load with the backup heater if the user activates this via the Malfunctioning main menu screen.

To keep energy consumption low, we recommend to set Emergency to auto SH reduced/DHW off if the house is unattended for longer periods.

Bivalent

Only applicable in case of auxiliary boiler.

About bivalent

The purpose of this function is to determine which heating source can/will provide the space heating, either the heat pump system or the auxiliary boiler.

# Code Description

[9.C.1] [C-02] Bivalent: Indicates if the space heating

is also performed by means of another heat source than the system.

▪ 0 No: Not installed

▪ 1 Yes: Installed. The auxiliary boiler

(gas boiler, oil burner) will operate when the outdoor ambient temperature is low. During bivalent operation, the heat pump is turned off. Set this value in case an auxiliary boiler is used.

▪ If Bivalent is enabled: When the outdoor temperature drops

below the bivalent ON temperature (fixed or variable based on energy prices), the space heating by the indoor unit stops automatically and the permission signal for the auxiliary boiler is active.

▪ If Bivalent is disabled: Space heating is only done by the indoor

unit within the operation range. The permission signal for the auxiliary boiler is always inactive.

The switch-over between the heat pump system and the auxiliary boiler is based on the following settings:

▪ [C‑03] and [C‑04]

▪ Electricity prices ([7.5.1], [7.5.2] and [7.5.3])

[C‑03], [C‑04], and T

Based on the settings above, the heat pump system calculates a value T

, which is variable between [C‑03] and [C‑03]+[C‑04].

INFORMATION

▪ The bivalent operation function has no impact on the

domestic water heating mode. The domestic hot water is still and only heated by the indoor unit.

▪ The permission signal for the auxiliary boiler is located

on the EKRP1HB (digital I/O PCB). When it is activated, the contact X1, X2 is closed and open when it is deactivated. See illustration below for the schematic location of this contact.

# Code Description

9.C.3 [C-03] Range: –25°C~25°C (step: 1°C)

9.C.4 [C-04] Range: 2°C~10°C (step: 1°C)

The higher the value of [C‑04], the higher the accuracy of the switch-over between the heat pump system and the auxiliary boiler.

To determine the value of [C‑03], proceed as follows:

1 Determine the COP (= coefficient of performance) using the

formula:

Formula Example

COP = (Electricity price / gas

(a)

price)

× boiler efficiency

If:

▪ Electricity price: 20c€/kWh

▪ Gas price: 6c€/kWh

▪ Boiler efficiency: 0.9

Then: COP = (20/6)×0.9 = 3

(a) Make sure to use the same units of measurement for the

electricity price and gas price (example: both c€/kWh).

2 Determine the value of [C‑03] using the graph:

Example:

a [C‑03]=2.5 in case of COP=3 and LWT=35°C

b [C‑03]=10.5 in case of COP=3 and LWT=55°C

NOTICE

Make sure to set the value of [5‑01] at least 1°C higher than the value of [C‑03].

Electricity prices

INFORMATION

Electricity price can only be set when bivalent is ON ([9.C.1] or [C-02]). These values can only be set in menu structure [7.5.1], [7.5.2] and [7.5.3]. Do NOT use overview settings.

Auto restart

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

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

Disable protections

INFORMATION

The software is equipped with an "installer-on-site" mode ([9.G]: Disable protections), that disables automatic operation by the unit. At first installation, setting Disable protections is by default set to Yes, meaning automatic operation is disabled. All protective functions are then disabled. To enable automatic operation and the protective functions, set Disable protections to No.

36 hours after the first power-on, the unit will automatically set Disable protections to No, 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 manually Disable protections to Yes.

Brine freezing temperature

Depending on the type and concentration of the anti-freeze in the brine system, the freezing temperature will differ. The following parameters set the units freeze up prevention limit temperature. To allow for temperature measurement tolerances, the brine concentration MUST resist to a lower temperature than the defined setting.

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 –2°C, then the unit freeze up prevention limit temperature MUST be set to –12°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.

NOTICE

The Brine freezing temperature setting can be modified and read out in [9.M].

After changing the setting in [9.M] or in the field settings overview [9.I], wait 10 seconds before restarting the unit via the user interface to ensure that the setting is saved in the memory correctly.

This setting can ONLY be modified if the communication between hydro module and compressor module is present. The communication between hydro module and compressor module is NOT guaranteed and/or applicable if:

▪ error "U4" appears on the user interface,

▪ the heat pump module is connected to preferential kWh

rate power supply where power supply is interrupted and preferential kWh rate power supply is activated.

11 Commissioning

NOTICE

Make sure that both the domestic hot water tank and the space heating circuit are filled before turning on the power of the unit.

If not filled before turning on power, and in case Emergency is active, the backup heater thermal fuse may blow. To avoid breakdown of the backup heater, fill the unit before turning on power.

INFORMATION

11.3 Checklist before commissioning

After the installation of the unit, first check the items listed below. Once all checks are fulfilled, the unit must be closed. Power-up the unit after it is closed.

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.

Backup heater circuit breaker F1B (field supply) is

turned ON.

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.

11.1 Overview: Commissioning

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

Typical workflow

Commissioning typically consists of the following stages:

1 Checking the “Checklist before commissioning”.

2 Performing an air purge on the water circuit.

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.

11.2 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

ALWAYS operate the unit with thermistors and/or pressure sensors/switches. If NOT, burning of the compressor might be the result.

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

The pressure relief valve purges water when opened. Clean water must come out.

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

The domestic hot water tank is filled completely.

The brine circuit and water circuit are filled correctly.

NOTICE

When the brine circuit is not ready to be used, the system can be set to HP forced off mode. To do this, set [9.5.2]=1 (HP forced off = enabled).

Space heating and domestic hot water are then provided by the backup heater. Cooling is NOT possible when this mode is active. All commissioning related to or making use of the brine circuit should NOT be performed until the brine circuit is filled and HP forced off is deactivated.

11.4 Checklist during commissioning

To perform an air purge on the water circuit.

To perform an air purge on the brine circuit via brine pump test run or 10-day brine operation function.

To perform a test run.

11 Commissioning

To perform an actuator test run.

Underfloor screed dryout function

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

To start 10-day brine pump operation.

11.4.1 Air purge function on the water 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.

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

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

The air purge function stops automatically after 30minutes.

To perform a manual air purge

Conditions: Make sure all operation is disabled. Go to [C]:

Operation and turn off Room, Space heating/cooling and Tank operation.

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

change the user permission level"[455].

2 Go to [A.3]: Commissioning > Air purge.

3 In the menu, set Type = Manual.

4 Select Start air purge.

5 Select OK to confirm.

Result: The air purge starts. It stops automatically

when ready.

—

6 During manual operation:

▪ You can change the pump speed.

▪ You must change the circuit.

To change these settings during the air purge, open the menu and go to [A.3.1.5]: Settings.

11.4.2 Air purge function on the brine circuit

When installing and commissioning the unit, it is very important to remove all air from the brine circuit.

NOTICE

It is required that the brine circuit is filled BEFORE the brine pump test run is activated.

There are 2 ways to perform an air purge:

▪ with a brine filling station (field supply),

▪ with a brine filling station (field supply) in combination with the

unit's own brine pump.

In both cases, follow the instructions included with the brine filling station. The second method should only be used when the air purge on the brine circuit was NOT successful using only a brine filling station.

In case a brine buffer vessel is present in the brine circuit, or if the brine circuit consists of a horizontal loop instead of a vertical borehole, further air purging may be required. You can make use of the 10 day brine pump operation. See "11.4.6To start or stop

10-day brine pump operation"[491] for more information.

To perform an air purge with a brine filling station

Follow the instructions included with the brine filling station (field supply).

14.3.1 Symptom: The unit is NOT heating 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

14 Troubleshooting

Possible causes Corrective action

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

▪ All shut-off valves of the water

or brine circuit are completely open.

▪ The water and brine filters are

clean. Clean if necessary (see

" Yearly maintenance: instructions"[492]).

▪ There is no air in the system.

Purge air if necessary (see

"11.4.1 Air purge function on the water circuit" [4 88] and "11.4.2 Air purge function on the brine circuit"[488]).

▪ The water pressure is >1 bar.

▪ The expansion vessel is NOT

broken.
