Unit for air to water heat pump system

4PW57621-1A

Both versions are delivered with an integrated backup heater for additional heating capacity during cold outdoor temperatures. The backup heater also serves as a backup in case of malfunctioning of the unit and for freeze protection of the outside water piping during winter time. The backup heater factory set capacity is 6 kW, however, depending on the installation, the installer can limit the backup heater capacity to 3 kW/2 kW. The backup heater capacity decision is a mode based on the equilibrium temperature, see scheme below.

1 Heat pump capacity 2 Required heating capacity (site dependent) 3 Additional heating capacity provided by the backup heater 4 Equilibrium temperature (can be set through the user interface,

refer to "Field settings" on page 28)

(*) - E(D/B)L* units include special equipment (insulation, heater

sheet, ...) to ensure good operation in areas where low ambient temperatures can occur together with high humidity conditions. In such conditions the E(D/B)H* units may experience problems with severe ice build-up on the air-cooled coil. In case such conditions are expected, the E(D/B)L* units must be installed instead.

- Both E(D/B)L* and E(D/B)H* units have a freeze prevention function using the pump and backup heater to keep the water system safe from freezing in all conditions. In case accidental or intentional power shutdown is likely to happen, we recommend to use glycol.

SAFETY CONSIDERATIONS

The precautions listed here are divided into the following four types. They all cover very important topics, so be sure to follow them carefully.

Meanings of DANGER, WARNING, CAUTION and NOTE symbols.

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

WARNING

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

NOTE

Indicates situations that may result in equipment or property-damage accidents only.

Danger

■ Before touching electric terminal parts, turn off power switch.

■ When service panels are removed, live parts can be easily

touched by accident. Never leave the unit unattended during installation or servicing

when the service panel is removed.

■ Do not touch water pipes during and immediately after operation as the pipes may be hot. Your hand may suffer burns. To avoid injury, give the piping time to return to normal temperature or be sure to wear proper gloves.

■ Do not touch any switch with wet ﬁngers. Touching a switch with wet ﬁngers can cause electrical shock.

■ Before touching electrical parts, turn off all applicable power supply.

Warning

■ Tear apart and throw away plastic packaging bags so that children will not play with them.

Children playing with plastic bags face danger of death by suffocation.

■ Safely dispose of packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

■

Ask your dealer or qualiﬁed personnel to carry out installation work Do not install the machine by yourself.

Improper installation may result in water leakage, electric shocks or ﬁre.

■ Perform installation work in accordance with this installation manual.

Improper installation may lead to water leakage, electric shocks or ﬁre.

■ Be sure to use only the speciﬁed accessories and parts for installation work.

Failure to use the speciﬁed parts may result in water leakage, electric shocks, ﬁre, or the unit falling.

■ Install the unit on a foundation that can withstand its weight.

■ Insufﬁcient strength may result in the fall of equipment and

causing injury.

■ Carry out the speciﬁed installation work in consideration of strong winds, hurricanes, or earthquakes.

Improper installation work may result in accidents due to fall of equipment.

■ Make certain that all electrical work is carried out by qualiﬁed personnel according to the local laws and regulations and this installation manual, using a separate circuit.

Insufﬁcient capacity of the power supply circuit or improper electrical construction may lead to electric shocks or ﬁre.

■ Be sure to install a earth leak detector according to local laws and regulations.

Failure to install a earth leak detector may cause electric shocks and ﬁre.

■ Make sure that all wiring is secure, using the speciﬁed wires and ensuring that external forces do not act on the terminal connections or wires.

Incomplete connection or ﬁxing may cause a ﬁre.

■ When wiring the power supply, form the wires so that the frontside panel can be securely fastened.

If the frontside panel is not in place, overheat of the terminals, electric shocks or a ﬁre may be caused.

■ After completing the installation work, check to make sure that there is no leakage of refrigerant gas.

■ Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.

■ Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant ﬂowing through the refrigerant piping, compressor and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

■ Do not touch the internal parts (pump, backup heater, etc.) during and immediately after operation.

Your hands may suffer burns if you touch the internal parts. To avoid injury, give the internal parts time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

Caution

■ For use of units in applications with temperature alarm settings it is advised to foresee a delay of 10 minutes for signalling the alarm in case the alarm temperature is exceeded. The unit may stop for several minutes during normal operation for "defrosting of the unit" or when in "thermostat-stop" operation.

■ Earth the unit. Earth resistance should be according to local laws and

regulations Do not connect the earth wire to gas or water pipes,

lightning conductor or telephone earth wire. Incomplete earthing may cause electric shocks.

■ Gas pipe.

Ignition or explosion may occur if the gas leaks.

■ Water pipe.

Hard vinyl tubes are not effective earths.

■ Lightning conductor or telephone earth wire.

Electric potential may rise abnormally if struck by a lightning bolt.

■ Install the power wire at least 1 meter away from televisions or radios to prevent image interference or noise.

(Depending on the radio waves, a distance of 1 meter may not be sufﬁcient to eliminate the noise.)

■ Do not rinse the unit. This may cause electric shocks or ﬁre.

■ Do not install the unit in places such as the following:

■ Where there is mist of mineral oil, oil spray or vapour.

Application 2

Space heating only application without room thermostat connected to the unit. The temperature in each room is controlled by a valve on each water circuit. Domestic hot water is provided through the domestic hot water tank which is connected to the unit.

Domestic water heating

When domestic water heating mode is enabled (either manually by the user, or automatically through a schedule timer) the target domestic hot water temperature will be achieved by a combination of the heat exchanger coil and the electrical booster heater.

When the domestic hot water temperature is below the user conﬁgured set point, the 3-way valve will be activated to heat the domestic water by means of the heat pump. In case of large domestic hot water demand or a high domestic hot water temperature setting, the booster heater (8) can provide auxiliary heating.

Pump operation and space heating and cooling

According to the season, the customer will select cooling or heating on the room thermostat (T). This selection is not possible by operating the user interface.

When space heating/cooling is requested by the room thermostat (T), the pump will start operating and the unit (1) will switch to "heating mode"/"cooling mode". The unit (1) will start operating to achieve the target leaving cold/hot water temperature.

In case of cooling mode, the motorised 2-way valve (11) will close as to prevent cold water running through the ﬂoor heating loops (FHL).

Make sure to connect the thermostat wires to the correct terminals (see "Connection of the thermostat cable" on

page 22) and to conﬁgure the DIP switch toggle switches

correctly (see "Room thermostat installation conﬁguration"

on page 25).

Wiring of the 2-way valve (11) is different for a NC (normal closed) valve and a NO (normal open) valve! Make sure to connect to the correct terminal numbers as detailed on the wiring diagram.

The ON/OFF setting of the heating/cooling operation is done by the room thermostat and cannot be done by the user interface.

Space heating and cooling

According to the season, the customer will select cooling or heating through the user interface.

The unit (1) will operate in cooling mode or heating mode to achieve the target leaving water temperature.

With the unit in heating mode, the 2-way valve (11) is open. Hot water is provided to both the fan coil units and the ﬂoor heating loops.

With the unit in cooling mode, the motorised 2-way valve (11) is closed to prevent cold water running through the ﬂoor heating loops (FHL).

When closing several loops in the system by remotely controlled valves, it might be required to install a by-pass valve (7) to avoid the ﬂow switch safety device from being activated. See also "Application 2" on page 8.

Wiring of the 2-way valve (11) is different for a NC (normal closed) valve and a NO (normal open) valve! Make sure to connect to the correct terminal numbers as detailed on the wiring diagram.

The ON/OFF setting of the heating/cooling operation is done by the user interface.

Application 5

Space heating with an auxiliary boiler (alternating operation)

Space heating application by either the Daikin unit or by an auxiliary boiler connected in the system. The decision whether either the E(D/B)* unit or the boiler will operate can be achieved by an auxiliary contact or an E(D/B)* indoor controlled contact.

The auxiliary contact can e.g. be an outdoor temperature thermostat, an electricity tariff contact, a manually operated contact, etc. See

"Field wiring conﬁguration A" on page 10.

The E(D/B)* unit controlled contact (also called 'permission signal for the auxiliary boiler") is determined by the outdoor temperature (thermistor located at the outdoor unit). See "Field wiring

conﬁguration B" on page 10.

Bivalent operation is only possible for space heating operation, not for the domestic water heating operation. Domestic hot water in such an application is always provided by the domestic hot water tank which is connected to the Daikin unit.

The auxiliary boiler must be integrated in the piping work and in the ﬁeld wiring according to the illustrations below.

Installation manual

NOTE

■ Conﬁguration A

Make sure that auxiliary contact (A) has sufﬁcient differential or time delay so as to avoid frequent changeover between the E(D/B)* unit and the boiler. If the auxiliary contact (A) is an outdoor temperature thermostat, make sure to install the thermostat in the shade, so that it is not inﬂuenced or turned ON/OFF by the sun.

Conﬁguration B

Make sure that the bivalent hysteresis [C-04] has sufﬁcient differential to avoid frequent changeover between the E(D/B)* unit and the boiler. As the outdoor temperature is measured via the outdoor unit, air thermistor make sure to install the outdoor unit in the shade, so that it is not inﬂuenced by the sun.

Frequent switching may cause corrosion of the boiler in an early stage. Contact the manufacturer of the boiler.

■ During heating operation of the E(D/B)* unit, the unit will operate so as to achieve the target leaving water temperature as set on the user interface. When weather dependent operation is active, the water temperature is determined automatically depending on the outdoor temperature.

During heating operation of the boiler, the boiler will operate so as to achieve the target leaving water temperature as set on the boiler controller.

Never set the target leaving water temperature set point on the boiler controller above 55°C.

■ Make sure to only have 1 expansion vessel in the water circuit. An expansion vessel is already premounted in the Daikin unit.

Application 6

Space heating with room thermostat application through ﬂoor heating loops and fan coil units. The ﬂoor heating loops and fan coil units require different operating water temperatures.

The ﬂoor heating loops require a lower water temperature in heating mode compared to fan coil units. To achive these two set points, a mixing station is used to adapt the water temperature according to requirements of the ﬂoor heating loops. The fan coil units are directly connected to the unit water circuit and the ﬂoor heating loops after the mixing station. The control of this mixing station is not done by the unit.

The operation and conﬁguration of the ﬁeld water circuit is the responsibility of the installer.

Daikin only offers a dual set point control function. By this function two set points can be generated. Depending on the required water temperature (ﬂoor heating loops and/or fan coil units are required) ﬁrst set point or second set point can be activated.

For conﬁguration B: Make sure to conﬁgure the ﬁeld settings [C-02, C-03 and C-04] correctly. Refer to

"Bivalent operation" on page 35.

CAUTION

Make sure that return water to the E(D/B)* heat exchanger never exceeds 55°C.

For this reason, never put the target leaving water temperature set point on the boiler controller above 55°C and install an aquastat

the E(D/B)* unit. Make sure that the non-return valves (ﬁeld supply) are

correctly installed in the system. Make sure that the room thermostat (th) is not frequently

turned ON/OFF. Daikin shall not be held liable for any damage resulting

from failure to observe this rule.

(a) The aquastat valve must be set for 55°C and must operate to close the return

water ﬂow to the unit when the measured temperature exceeds 55°C. When the temperature drops to a lower level, the aquastat valve must operate to open the return water ﬂow to the E(D/B)* unit again.

Manual permission towards the E(D/B)* unit on the boiler. In case only the E(D/B)* unit should operate in space

heating mode, disable the bivalent operation via setting [C-02].

In case only the boiler should operate in space heating mode, increase the bivalent ON temperature [C-03] to 25°C.

The advantage of the dual set point control is that the heat pump will/can operate at the lowest required leaving water temperature when only ﬂoor heating is required. Higher leaving water temperatures are only required in case fan coil units are operating. This results in a better performance of the heat pump.

Pump operation and space heating

When the room thermostat for the ﬂoor heating loop (T1) and the fan coil units (T2) are connected to the indoor unit, the pump (4) will operate when there is a request for heating from T1 and/or T2. The outdoor unit will start operating to achieve the target leaving water temperature. The target leaving water temperature depends on which room thermostat is requesting heating.

Main components

NOTE

■ Make sure to connect the thermostat wires to the

correct terminals (see "Overview of the unit" on

page 12).

■ Make sure to conﬁgure the ﬁeld settings [7-02],

[7-03] and [7-04] correctly. Refer to "Dual set point

control" on page 33.

■ Make sure to conﬁgure the DIP switch SS2-3 on

the PCB of the E(D/B)* switch box correctly. Refer to "Room thermostat installation conﬁguration" on

page 25.

■ The request signals for space heating can be

implemented in two different ways (installer choice).

- Thermo ON/OFF signal from room thermostat

- Status signal (active/not active) from the mixing station

■ It is the installers responsibility to make sure no unwanted situations can occur (e.g. too high water temperatures towards ﬂoor heating loops, etc.)

■ Daikin does not offer any type of mixing station. Dual set point control only provides the possibility to use two set points.

■ When only zone A request heating, zone B will be fed with water at a temperature equal to the ﬁrst set point. This can lead to unwanted heating of zone B.

■ When only zone B request heating, the mixing station will be fed with water at a temperature equal to the second set point. Depending on the control of the mixing station, the ﬂoor heating loop can still receive water at a temperature equal to set point of the mixing station.

Be aware that the actual water temperature through the ﬂoor heating loops depends on the control and setting of the mixing station.

Checking the water circuit

The units are equipped with a water inlet and water outlet for connection to a water circuit. This circuit must be provided by a licensed technician and must comply with local laws and regulations.

The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping.

Before continuing the installation of the unit, check the following points:

■ The maximum water pressure = 3 bar + static pressure of pump.

■ The maximum water temperature is 65°C according to safety

device setting.

■ Always use materials which are compatible with the water used in the system and with the materials used in the unit.

■ Ta ke care that the components installed in the ﬁeld piping can withstand the water pressure and temperature.

■ Drain taps must be provided at all low points of the system to permit complete drainage of the circuit during maintenance.

A drain valve is provided in the unit to drain the water from the unit water system.

■ Air vents must be provided at all high points of the system. The vents should be located at points which are easily accessible for servicing. An automatic air purge is provided inside the unit. Check that this air purge valve is not tightened too much so that automatic release of air in the water circuit remains possible.

■ Select piping diameter in relation to required water ﬂow and available ESP of the pump.

■ The minimum required water ﬂow for the unit operation is 16 l/min. When the water ﬂow is lower than this minimum value, ﬂow error 7H will be displayed and the operation of the indoor unit will be stopped.

Checking the water volume and expansion vessel pre-pressure

The unit is equipped with an expansion vessel of 10 litre which has a default pre-pressure of 1 bar.

To assure proper operation of the unit, the pre-pressure of the expansion vessel might need to be adjusted and the minimum and maximum water volume must be checked.

1 Check that the total water volume in the installation, excluding

the internal water volume of the unit, is 20 l minimum. Refer to

"Technical speciﬁcations" on page 43 to know the internal water

volume of the unit.

E(D/B)(H/L)Q011~016BA6V3+W1

Unit for air to water heat pump system

4PW57621-1A

In most applications this minimum water volume will have a satisfying result.

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

Installation manual

NOTE

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

Checking the maximum allowed water volume

To determine the maximum allowed water volume in the entire circuit, proceed as follows:

1 Determine for the calculated pre-pressure (Pg) the

corresponding maximum water volume using the graph below.

2 Check that the total water volume in the entire water circuit is

lower than this value.

If this is not the case, the expansion vessel inside the unit is too small for the installation.

[l]

= pre-pressure = maximum water volume

Example 1

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

In this example, no action or adjustment is required.

Example 2

The unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 350 l.

Result:

■ Since 350 l is higher than 280 l, the pre-pressure must be decreased (see table above).

■ The required pre-pressure is:

= (H

(bar)

/10+0.3) bar = (0/10+0.3) bar = 0.3 bar

(m)

■ The corresponding maximum water volume can be read from the graph: approximately 410 l.

■ Since the total water volume (350 l) is below the maximum water volume (410 l), the expansion vessel sufﬁces for the installation.

Setting the pre-pressure of the expansion vessel

When it is required to change the default pre-pressure of the expansion vessel (1 bar), keep in mind the following guidelines:

■ Use only dry nitrogen to set the expansion vessel pre-pressure.

■ Inappropriate setting of the expansion vessel pre-pressure will

lead to malfunction of the system. Therefore, the pre-pressure should only be adjusted by a licensed installer.

Unit for air to water heat pump system

4PW57621-1A

Connecting the water circuit

Water connections must be made in accordance with local regulations and the outlook diagram delivered with the unit, respecting the water in- and outlet.

Be careful not to deform the unit piping by using excessive force when connecting the piping. Deformation of the piping can cause the unit to malfunction.

If air, moisture or dust gets in the water circuit, problems may occur. Therefore, always take into account the following when connecting the water circuit:

■ Use clean pipes only.

■ Hold the pipe end downwards when removing burrs.

■ Cover the pipe end when inserting it through a wall so that no

dust and dirt enter.

■ Use a good thread sealant for the sealing of the connections. The sealing must be able to withstand the pressures and temperatures of the system.

■ When using non-brass metallic piping, make sure to insulate both materials from each other to prevent galvanic corrosion.

■ Because brass is a soft material, use appropriate tooling for connecting the water circuit. Inappropriate tooling will cause damage to the pipes.

NOTE

■ The unit is only to be used in a closed water system. Application in an open water circuit can lead to excessive corrosion of the water piping.

■ Never use Zn-coated parts in the water circuit. Excessive corrosion of these parts may occur as copper piping is used in the unit's internal water circuit.

■ When using a 3-way valve in the water circuit. Preferably choose a ball type 3-way valve to

guarantee full separation between domestic hot water and ﬂoor heating water circuit.

■ When using a 3-way valve or a 2-way valve in the water circuit.

The recommended maximum changeover time of the valve should be less than 60 seconds.

Protecting the water circuit against freezing

Frost can cause damage to the hydraulic system. As this unit is installed outdoors and thus the hydraulic system is exposed to freezing temperatures, care must be taken to prevent freezing of the system.

All hydraulic parts are insulated to reduce heat loss. Insulation must be foreseen on the ﬁeld piping.

The unit is already equipped with several features to prevent freezing.

■ The software contains special functions using pump and back up heater to protect the complete system against freezing.

This function will only be active when the unit is off.

■ Only for EDL and EBL units: As extra safety, a heatertape is winded around the piping to protect vital parts of the hydraulic system inside the unit.

This heatertape will only be active in case of an abnormal situation concerning the pump and will only protect internal parts of the unit. It can not protect ﬁeld installed parts outside the unit.

Field heater tape must be foreseen by the installer.

However in case of power failure, above mentioned features can not protect the unit from freezing.

If power failure can happen at times the unit is unattended, Daikin recommends adding glycol to the water system. Refer to Caution:

"Use of glycol" on page 16.

Refer to "[4-04] Freeze protection function" on page 31. Depending on the expected lowest outdoor temperature, make sure

the water system is ﬁlled with a weight concentration of glycol as mentioned in the table below.

Minimum outdoor temperature Glycol

–5°C 10% –10°C 15% –15°C 20% –20°C 25% –25°C 30%

(a)(b)(c)

WARNING

(a)

ETHYLENE GLYCOL IS TOXIC

(b)

The concentrations mentioned in the table above will not prevent the medium from freezing, but prevent the hydraulics from bursting.

(c)

The maximum allowed water volume is then reduced according to the ﬁgure "Maximum allowed water

volume" on page 15.

Caution: "Use of glycol"

Caution: Use of glycol

■ For installations with a domestic hot water tank, the use of propylene glycol, including necessary inhibitors, is only allowed if classiﬁed as Category 3 according to EN1717 or equivalent based on national regulations.

■ In case of over-pressure when using glycol, be sure to connect the safety valve to a drain pan in order to recover the glycol.

For this purpose a knock out hole is foreseen in the backplate of the unit making it possible to connect a drain pipe to the safety valve.

Connecting a drain pipe is not required if no glycol is used. The discharged water is then drained via the bottom of the unit.

Corrosion of the system due to presence of glycol

Uninhibited glycol will turn acidic under the inﬂuence of oxygen. This process is accelerated by presence of copper and at higher temperatures. The acidic uninhibited glycol attacks metal surfaces and forms galvanic corrosion cells that cause severe damage to the system.

It is therefore of extreme importance:

■ that the water treatment is correctly executed by a qualiﬁed water specialist;

■ that a glycol with corrosion inhibitors is selected to counteract acids formed by the oxidation of glycols;

■ that in case of an installation with a domestic hot water tank, only the use of propylene glycol, including necessary inhibitors classiﬁed as Category 3 according to EN1717 or equivalent based on national regulations is allowed. In other installations the use of ethylene glycol is permitted as well;

■ that no automotive glycol is used because their corrosion inhibitors have a limited lifetime and contain silicates which can foul or plug the system;

■ that galvanized piping is not used in glycol systems since its presence may lead to the precipitation of certain components in the glycol’s corrosion inhibitor;

■ that it has to be made sure the glycol is compatible with the used materials in the system.

Unit for air to water heat pump system

4PW57621-1A

Installation manual

NOTE

Also refer to "Checks before initial start-up" on page 27.

Be aware of the hygroscopic property of glycol: it absorbs moisture from its environment.

Leaving the cap off the glycol container causes the concentration of water to increase. The glycol 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 glycol to air.

Charging water

1 Connect the water supply to a drain and ﬁll valve (see "Main

components" on page 12).

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

turns).

3 Fill with water until the manometer indicates a pressure of

approximately 2.0 bar. Remove air in the circuit as much as possible using the air purge valves. Air present in the water circuit might cause malfunctioning of the backup heater.

4 Check that the backup heater vessel is ﬁlled with water by

opening the pressure relief valve. Water must ﬂow out of the valve.

NOTE

■ During ﬁlling, it might not be possible to remove all air in the system. Remaining air will be removed through the automatic air purge valves during ﬁrst operating hours of the system. Additional ﬁlling with water afterwards might be required.

■ 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 should remain above 1 bar to avoid air entering the circuit.

■ The unit might dispose some excessive water through the pressure relief valve.

■ Water quality must be according to EN directive 98/83 EC.

If no glycol is in the system in case of a power supply failure or pump operating failure, drain the system (as suggested in the ﬁgure below).

When water is at standstill inside the system, freezing is very likely to happen and damaging the system in the process.

Piping insulation

The complete water circuit, inclusive all piping, must be insulated to prevent condensation during cooling operation and reduction of the heating and cooling capacity as well as prevention of freezing of the outside water piping during winter time. The thickness of the sealing materials must be at least 13 mm with 0.039 W/mK in order to prevent freezing on the outside water piping.

If the temperature is higher than 30°C and the humidity is higher than RH 80%, then the thickness of the sealing materials should be at least 20 mm in order to avoid condensation on the surface of the sealing.

Field wiring

WARNING

■ A main switch or other means for disconnection, having a contact separation in all poles, must be incorporated in the ﬁxed wiring in accordance with relevant local laws and regulations.

■ Switch off the power supply before making any connections.

■ Use only copper wires.

■ For W1

Make sure to connect power supply cables in normal phase. If connected in reverse phase, the remote controller of the indoor unit indicates " equipment cannot operate. Change any two of the three power supply cables (L1, L2, L3) to correct phase.

■ Never squeeze bundled cables and make sure that it does not come in contact with the piping and sharp edges.

Make sure no external pressure is applied to the terminal connections.

■ All ﬁeld wiring and components must be installed by a licensed electrician and must comply with relevant local laws and regulations.

■ The ﬁeld wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions given below.

■ Be sure to use a dedicated power supply. Never use a power supply shared by another appliance.

■ Be sure to establish an earth. Do not earth the unit to a utility pipe, surge absorber, or telephone earth. Incomplete earth may cause electrical shock.

■

■ Be sure to install the required fuses or circuit

DANGER

Be sure to install an earth leakage circuit breaker in accordance with relevant local and national regulations. Failure to do so may cause electrical shock.

Precautions on electrical wiring work

■ Fix cables so that cables do not make contact with the pipes (especially on high pressure side).

■ Secure the electrical wiring with cable ties as shown in ﬁgure 2 so that it does not come in contact with the piping, particularly on the high-pressure side.

■ Make sure no external pressure is applied to the terminal connectors.

■ When installing the earth leak detector make sure that it is compatible with the inverter (resistant to high frequency electrical noise) to avoid unnecessary opening of the earth leak detector.

NOTE

The earth leak detector must be a high-speed type breaker of 30 mA (<0.1 s).

■ As this unit is equipped with an inverter, installing a phase advancing capacitor not only will deteriorate power factor improvement effect, but also may cause capacitor abnormal heating accident due to high-frequency waves. Therefore, never install a phase advancing capacitor.

Connection to a beneﬁt 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 beneﬁt 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 beneﬁt kWh rate power supply delivery systems available, if any.

When the equipment is connected to such beneﬁt 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 unit is designed to receive an input signal by which the unit switches into forced off mode. At that moment, the outdoor unit compressor will not operate.

CAUTION for a beneﬁt kWh rate power supply like illustrated

below as type 1 (allowed for all models)

■ If the beneﬁt kWh rate power supply is of the type that power supply is not interrupted, then control of the heaters is still possible.

For the different possibilities of controlling heaters at moments that beneﬁt kWh rate is active, refer to

"[D] Beneﬁt kWh rate power supply/Local shift value weather dependent" on page 35.

If heaters must be controlled at moments that the beneﬁt kWh rate power supply is off, then these heaters shall be connected to a separate power supply.

■ During the period that the beneﬁt kWh rate is active and power supply is continuous, then stand-by power consumption is possible (PCB, controller, pump, ...).

for a beneﬁt kWh rate power supply like illustrated below as types 2 or 3 (only allowed for EDL and EBL models)

If during beneﬁt kWh rate power supply the power supply is shut off, then heaters can not be controlled.

■ This power supply interruption should not be longer than 2 hours, otherwise the real time clock of the controller will be reset.

■ During power supply interruption, the controller display will be blank.

If during beneﬁt kWh rate power supply the power supply is shut off, the freeze protection function (refer to "[4-04]

Freeze protection function" on page 31) can not operate.

For this reason it is important that the power supply of the expansion vessel heater, plate heat exchanger heater and switch box heater are changed to guarantee freeze protection.

Without room thermostat: DIP switch SS2-3=OFF

When no thermostat is connected to the unit, pump operation will be determined by the leaving water temperature.

To f orce continuous pump operation when no room thermostat is connected do the following:

- set toggle switch SS2-3 to ON,

- short-circuit the terminal numbers 1-2-4 on the terminal block in the switch box.

With room thermostat: DIP switch SS2-3=ON

When a thermostat is connected to the unit, the pump will operate continuously whenever there is heating or cooling demand requested by the thermostat.

Dual set point

When dual set point is enabled, the pump operation will be determined depending on the status of the DIP switch SS2-3 and set point selection contacts. Refer to the pump operation conﬁgurations when the thermostat is connected or not as described above.

When dual set point is enabled, the "forced continuous pump operation" is not possible. When SS2-3 is ON while SP1 and SP2 are both closed, the pump operation will be the same operation as "with room thermostat" and the second set point will be the applicable set point. Refer to

"Dual set point control" on page 33.

When SS2-3 was set to ON without all necessary and correct wiring connections between indoor unit and switch box of the domestic hot water tank, the error code AC will be displayed on the user interface.

Initial start-up at low outdoor ambient temperatures

During initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so may result in cracking of concrete ﬂoors due to rapid temperature change. Please contact the responsible cast concrete building contractor for further details.

To do so, the lowest leaving water set temperature can be decreased to a value between 15°C and 25°C by adjusting the ﬁeld setting [9-01] (heating set point lower limit). Refer to "Field settings" on

page 28.

NOTE

Heating between 15°C and 25°C is performed by the backup heater only.

Check the inside of the unit on refrigerant leakage. If there is a refrigerant leak, call your local dealer.

10 Power supply voltage

Check the power supply voltage on the local supply panel. The voltage must correspond to the voltage on the identiﬁcation label of the unit.

11 Air purge valve

Make sure the air purge valve is open (at least 2 turns).

12 Pressure relief valve

Check if the backup heater vessel is completely ﬁlled with water by operating the pressure relief valve. It should purge water instead of air.

NOTE

Operating the system with the backup heater not completely ﬁlled with water will damage the backup heater!

When power supply to the unit is turned on, "88" is displayed on the user interface during its initialisation, which might take up to 30 seconds. During this process the user interface cannot be operated.

Setting the pump speed

The pump speed can be selected on the pump (see "Main

components" on page 12).

The default setting is high speed (I). If the water ﬂow in the system is too high (e.g., noise of running water in the installation) the speed can be set to low speed (II).

NOTE

The speed dial on the pump indicates 3 speed settings. However, only 2 speed settings exist: low speed and high speed. The indicated medium speed setting on the speed dial is equal to low speed.

The available external static pressure (ESP, expressed in kPa) in function of the water ﬂow (l/min) is shown in the graph below.

Failure diagnosis at the moment of ﬁrst installation

■ In case nothing is displayed on the remote controller (the current set temperature does not display), check for any of the following abnormalities before you can diagnose possible malfunction codes.

■ Disconnection or wiring error (between power supply and unit

and between unit and remote controller).

■ The fuse on the PCB may have run out.

■ If the remote controller shows "E3", "E4" or "L8" as an error code,

there is a possibility that either the stop valves are closed, or that air inlet or air outlet are blocked.

■ If the error code "U2" is displayed on the remote controller, check for voltage imbalance.

■ If the error code possible that air inlet or air outlet are blocked.

"L4"

is displayed on the remote controller, it is

13 Shut-off valves

Make sure that the shut-off valves are fully open.

Operating the system with closed valves will damage the pump!

■ The reversed phase protection detector of this product only works during the initialisation stage after a power reset.

The reversed phase protection detector is designed to stop the product in case of an abnormality when the product is started up.

■ When the reversed phase protection circuit forced the unit to

stop, check if all phases are existing. If this is the case, shut off the power supply to the unit and replace two of three phases. Turn on power again and start the unit.

■ Reversed phase detection is not performed while the product

is operating.

■ In case of possible reversal of phases after a momentary

black out of power and the power goes on and off while the product is operating, install a reversed phase protection circuit on site. Such situation is not unimaginable when using generators. Running the product in reversed phase can break the compressor and other parts.

■ For a missing phase in case of W1 units, "

" or "U2" will be

displayed on the remote controller of the unit.

Operation will be impossible with either one of these phenomena. If this happens, turn off the power, re-check the wiring and switch the position of two of the three electrical wires.

Field settings

The unit shall be conﬁgured by the installer to match the installation environment (outdoor climate, installed options, etc.) and user demand. Thereto, a number of so called ﬁeld settings are available. These ﬁeld settings are accessible and programmable through the user interface.

Each ﬁeld setting is assigned a 3-digit number or code, for example [5-03], which is indicated on the user interface display. The ﬁrst digit [5] indicates the 'ﬁrst code' or ﬁeld setting group. The second and third digit [03] together indicate the 'second code'.

A list of all ﬁeld settings and default values is given under "Field

settings table" on page 37. In this same list, we provided for 2

columns to register the date and value of altered ﬁeld settings at variance with the default value.

A detailed description of each ﬁeld setting is given under "Detailed

description" on page 28.

Procedure

To change one or more ﬁeld settings, proceed as follows.

3 Press the bgj button to select the appropriate ﬁeld

setting second code.

4 Press the pfi button and pfj button to change

the set value of the select ﬁeld setting.

5 Save the new value by pressing the pr button. 6 Repeat step 2 through 4 to change other ﬁeld settings as

required.

7 When ﬁnished, press the z button to exit FIELD SET MODE

NOTE

Changes made to a speciﬁc ﬁeld setting are only

stored when the pr button is pressed. Navigating to a new ﬁeld setting code or pressing the z button will discard the change made.

NOTE

■ Before shipping, the set values have been set as shown under "Field settings table" on page 37.

■ When exiting FIELD SET MODE, "88" may be displayed on the user interface LCD while the unit initialises itself.

[1] Weather dependent set point (heating operation only)

The weather dependent set point ﬁeld settings deﬁne the parameters for the weather dependent operation of the unit. When weather dependent operation is active the water temperature is determined automatically depending on the outdoor temperature: colder outdoor temperatures will result in warmer water and vice versa. During weather dependent operation, the user has the possibility to shift up or down the target water temperature by a maximum of 5°C. See the operation manual for more details on weather dependent operation.

■ [1-00] Low ambient temperature (Lo_A): low outdoor temperature.

■ [1-01] High ambient temperature (Hi_A): high outdoor temperature.

■ [1-02] Set point at low ambient temperature (Lo_Ti): the target outgoing water temperature when the outdoor temperature equals or drops below the low ambient temperature (Lo_A). Note that the Lo_Ti value should be higher than Hi_Ti, as for colder outdoor temperatures (i.e. Lo_A) warmer water is required.

■ [1-03] Set point at high ambient temperature (Hi_Ti): the target outgoing water temperature when the outdoor temperature equals or rises above the high ambient temperature (Hi_A). Note that the Hi_Ti value should be lower than Lo_Ti, as for warmer outdoor temperatures (i.e. Hi_A) less warm water sufﬁces.

[2] Disinfection function

Applies only to installations with a domestic hot water tank. The disinfection function disinfects the domestic hot water tank by

periodically heating the domestic water to a speciﬁc temperature.

CAUTION

The disinfection function ﬁeld settings must be conﬁgured by the installer according to local laws and regulations.

■ [2-00] Operation interval: day(s) of the week at which the domestic water should be heated.

■ [2-01] Status: deﬁnes whether the disinfection function is turned on (1) or off (0).

■ [2-02] Start time: time of the day at which the domestic water should be heated.

■ [2-03] Set point: high water temperature to be reached.

■ [2-04] Interval: time period deﬁning how long the set point

temperature should be maintained.

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

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

[3] Auto restart

When power returns after a power supply failure, the auto restart function reapplies the user interface settings at the time of the power supply failure.

[4] Backup heater operation and space heating off temperature

Backup heater operation

The operation of the backup heater can be enabled or disabled, or it can be disabled depending on operation of the booster heater.

■ [4-00] Status: deﬁnes whether backup heater operation is enabled (1) or disabled (0).

NOTE

Even in case the backup heater operation status ﬁeld setting [4-00] is disabled (0), the backup heater can operate during start-up and defrost operation.

■ [4-01] Priority: deﬁnes whether backup heater and booster heater can operate simultaneously (0), or if the booster heater operation has priority over the backup heater operation (1), or if the backup heater operation has priority over the booster heater operation (2).

NOTE

When the priority ﬁeld setting is set to ON (1), space heating performance of the system might be decreased at low outdoor temperatures, since in case of domestic water heating demand the backup heater will not be available for space heating (space heating will still be provided by the heat pump).

When the priority ﬁeld setting is set to ON (2), domestic water heating performance of the system might be decreased at low outdoor temperatures, since in case of space heating demand the booster heater will not be available for domestic water heating. However domestic water heating by heat pump will still be available.

When the priority ﬁeld setting is set to OFF (0), make sure that electrical power consumption does not exceed supply limits.

Space heating off temperature

■ [4-02] Space heating off temperature: outdoor temperature above which space heating is turned off, to avoid overheating.

Booster heater operation

Applies only to installations with a domestic hot water tank. The operation of the booster heater can be enabled or limited

depending on outdoor temperature (TA), domestic hot water temperature (T

) or operation mode of the heat pump.

DHW

■ [4-03] Booster heater operation: deﬁnes whether the optional booster heater operation is enabled (1) or has certain limitations (0/2/3).

Explanation of settings of [4-03]

Booster heater will/can only operate if domestic hot water mode is activated (w).

■ [4-03]=0, then booster heater operation is only allowed during "[2] Disinfection function" and "Powerful domestic water heating" (see operation manual). This setting is only recommended in case the capacity of the heat pump can cover the heating requirements of the house and domestic hot water over the complete heating season. The result of this setting is that the domestic hot water will never be heated by the booster heater except for "[2] Disinfection function" and "Powerful domestic water heating" (see operation manual).

If the booster heater operation is limited ([4-03]=0) and the ambient outdoor temperature TA is lower than the ﬁeld setting to which parameter [5-03] is set and [5-02]=1, then the domestic hot water will not be heated.

The consequence of this setting is that the domestic hot water temperature (T heat pump OFF temperature (T

) can be maximum the

DHW

HP OFF

). Refer to

setting of [6-00] and [6-01] in "[6]" on page 32.

■ [4-03]=1, then booster heater heater operation is only determined by booster heater OFF temperature (T booster heater ON temperature (T

) and/or schedule

BH ON

BH OFF

timer. Refer to setting "[7-00]" on page 32 and "[7-01]" on

page 33.

■ [4-03]=2, then booster heater operation is only allowed if heat pump is out of "operation range" of heat pump domestic water heating mode (TA<[5-03] or TA>35°C) or domestic hot water temperature is 2°C lower than the heat pump OFF temperature (T (T

DHW>THP OFF–

) for domestic hot water mode

HP OFF

2°C). (Refer to setting [5-03] on page 31, [6-00] on page 32 and [6-01] on page 32). Results in the most optimum coverage of domestic hot water heated by the pump.

■ [4-03]=3, then booster heater operation is the same as setting 1, except that booster heater is OFF when the heat pump is active in domestic hot water mode. The consequence of this functionality is that setting [8-03] is not relevant. Results in optimum coverage of domestic hot water heated by heat pump in relation with [8-04].

Unit for air to water heat pump system

4PW57621-1A

■ When setting [4-03]=1/2/3, the booster heater operation can still be restricted by the schedule timer as well. I.e., when booster heater operation is preferred during certain period of the day. (See operation manual)

■ When setting [4-03]=2, the booster heater will be allowed to operate when TA<[5-03] independent of the status of [5-02]. If bivalent operation is enabled and permission signal for auxiliary boiler is ON, the booster heater will be restricted even when T

<[5-03]. (See "[C-02]" on page 35).

■ Booster heater is always allowed during powerful and disinfection function, except for the period that the backup heater operation is required for safety reasons and [4-02]=1.

Installation manual

■ [4-04] Freeze protection function: avoids freezing of the water piping between home and unit. In case of low ambient temperatures it will activate the pump and in case of low water temperatures it will additionally activate the backup heater. Default freeze protection function takes into account freezing of water piping which is insufﬁciently insulated. Basically it means that the pump is activated whenever ambient temperatures become close to freezing, independently of the working temperature.

[5] Equilibrium temperature and space heating priority temperature

Equilibrium temperature — The 'equilibrium temperature' ﬁeld

settings apply to operation of the backup heater. When the equilibrium temperature function is enabled, operation of the backup heater is restricted to low outdoor temperatures, i.e. when the outdoor temperature equals or drops below the speciﬁed equilibrium temperature. When the function is disabled, operation of the backup heater is possible at all outdoor temperatures. Enabling this function reduces the working time of the backup heater.

■ [5-00] Equilibrium temperature status: speciﬁes whether the equilibrium temperature function is enabled (1) or disabled (0).

■ [5-01] Equilibrium temperature: outdoor temperature below which operation of the backup heater is allowed.

Space heating priority temperature

— Applies only to installations

with a domestic hot water tank. — The 'space heating priority temperature' ﬁeld settings apply to operation of the 3-way valve and the booster heater in the domestic hot water tank. When the space heating priority function is enabled, it is assured that the full capacity of the heat pump is used for space heating only when the outdoor temperature equals or drops below the speciﬁed space heating priority temperature, i.e. low outdoor temperature. In this case the domestic hot water will only be heated by the booster heater.

■ [5-02] Space heating priority status: speciﬁes whether space heating priority is enabled (1) or disabled (0).

■ [5-03] Space heating priority temperature: outdoor temperature below which the domestic hot water will be heated by the booster heater only, i.e. low outdoor temperature.

■ [5-04] Set point correction for domestic hot water temperature: set point correction for the desired domestic hot water temperature, to be applied at low outdoor temperature when space heating priority is enabled. The corrected (higher) set point will make sure that the total heat capacity of the water in the tank remains approximately unchanged, by compensating for the colder bottom water layer of the tank (because the heat exchanger coil is not operational) with a warmer top layer.

[6] DT for heat pump domestic water heating mode

Applies only to installations with a domestic hot water tank. The 'DT (temperature difference) for heat pump domestic water

heating mode' ﬁeld settings determine the temperatures at which heating of the domestic hot water by the heat pump will be started (i.e., the heat pump ON temperature) and stopped (i.e., the heat pump OFF temperature). When the domestic hot water temperature drops below the heat pump ON temperature (T

), heating of the domestic hot water by

HP ON

the heat pump will be started. As soon as the domestic hot water temperature reaches the heat pump OFF temperature (T

HP OFF

) or the user set point temperature (TU), heating of the domestic hot water by the heat pump will be stopped (by switching the 3-way valve).

The heat pump OFF temperature, and the heat pump ON temperature, and its relation with ﬁeld settings [6-00] and [6-01] are explained in the illustration below.

[7] DT for booster heater and dual set point control

DT for booster heater

Applies only to installations with a domestic hot water tank. When the domestic hot water is heated and the domestic hot water

set point temperature (as set by the user) has been reached, the booster heater will continue to heat the domestic hot water to a temperature a few degrees above the set point temperature, i.e. the booster heater OFF temperature. These extra degrees are speciﬁed by the domestic hot water step length ﬁeld setting. Correct setting prevents the booster heater from repeatedly turning on and off (i.e. chattering) to maintain the domestic hot water set point temperature. Note: the booster heater will turn back on when the domestic hot water temperature drops [7-01] (ﬁeld setting) below the booster heater OFF temperature.

If the schedule timer for booster heater (see the operation manual) is active, the booster heater will only operate if allowed by this schedule timer.

Be aware that the domestic hot water temperature will be automatically increased (always) with the value selected in ﬁeld setting [7-00] compare to the user set point for domestic hot water (TU). Refer to ﬁeld setting [7-00] and the operation manual to select preferable set point.

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

■ The ﬁrst set point heating/cooling is the set point selected on the user interface.

- In heating mode the ﬁrst set point can be a

ﬁxed value or weather dependent.

- In cooling mode the ﬁrst set point is always a

ﬁxed value.

■ The second set point heating [7-03] should be linked to the heat emitters which requires the highest set point in heating mode. Example: fan coil unit.

■ The second set point cooling [7-04] should be linked to the heat emitters which requires the lowest set point in cooling mode. Example: fain coil unit.

■ The actual second set point heating value depends on the selected value of setting [7-03].

- In case [7-03]=1~24°C, the actual second set

point will be ﬁrst set point heating increased with [7-03] (the maximum is 55°C). In this way the second set point heating is linked to the ﬁrst set point heating.

- In case [7-03]=25~55°C, the actual second set

point heating is equal to [7-03].

■ The selection of second set point or ﬁrst set point is determined by the terminals (X2M: 1, 2, 4). The second set point has always priority on the ﬁrst set point.

[8] Domestic water heating mode timer

Applies only to installations with a domestic hot water tank. The 'domestic water heating mode timer' ﬁeld settings deﬁnes the

minimum and maximum domestic water heating times, minimum time between two domestic water heating cycles by heat pump, and booster heater delay time.

■ [8-00] Minimum running time: speciﬁes the minimum time period during which heat pump domestic water heating mode should be activated, even when the target domestic hot water temperature for heat pump (T

) has already been

HP OFF

reached.

■ [8-01] Maximum running time: speciﬁes the maximum time period during which heat pump domestic water heating mode can be activated, even when the target domestic hot water temperature for heat pump (T

) has not yet been

HP OFF

reached. The actual maximum running time will automatically vary between [8-01] and [8-01]+[8-04] depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 34.

Note that when the unit is conﬁgured to work with a room thermostat (refer to "Room thermostat

installation conﬁguration" on page 25), the

maximum running timer will only be taken into account when there is a request for space cooling or space heating. When there is no request for room cooling or room heating, domestic water heating by the heat pump will continue until the 'heat pump OFF temperature' (see ﬁeld settings [6] on page 32) is reached. When no room thermostat is installed, the timer is always taken into account.

■ [8-02] Anti-recycling time: speciﬁes the minimum required interval between two heat pump domestic water heating mode cycles. The actual anti-recycling time will automatically vary between [8-02] and 0 depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 34.

NOTE

It is the responsibility of the installer to make sure no unwanted situations can occur.

It is very important that the water temperature to the ﬂoor heating loops never becomes too high in heating mode or never too cold in cooling mode. Failure to observe this rule can result in construction damage or discomfort. For example in cooling mode condensation on the ﬂoor can occur when water towards the ﬂoor heating loops is too cold (dew point).

■ By adapting the booster heater delay time versus the maximum running time, an optional balance can be found between the energy efﬁciency and the heat up time.

■ However, if the booster heater delay time is set too high, it might take a long time before the domestic hot water reaches its set temperature upon domestic hot water mode request.

■ The purpose of [8-03] is to delay the booster heater in relation with the heat pump operation time in domestic water heating mode.

■ The setting [8-03] has only meaning if setting [4-03]=1. Setting [4-03]=0/2/3 limits the booster heater automatically in relation to heat pump operation time in domestic water heating mode.

■ Ta ke care that [8-03] is always in relation with the maximum running time [8-01].

[9] Cooling and heating set point ranges

The purpose of this ﬁeld setting is to prevent the user from selecting a wrong (i.e., too hot or too cold) leaving water temperature. Thereto the heating temperature set point range and the cooling temperature set point range available to the user can be conﬁgured.

CAUTION

■ 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.

■ In case of a ﬂoor cooling application, it is important to limit the minimum leaving water temperature at cooling operation (ﬁeld setting of parameter [9-03]) to 16~18°C to prevent condensation on the ﬂoor.

■ [9-00] Heating set point upper limit: maximum leaving water temperature for heating operation.

■ [9-01] Heating set point lower limit: minimum leaving water temperature for heating operation.

■ [9-02] Cooling set point upper limit: maximum leaving water temperature for cooling operation.

■ [9-03] Cooling set point lower limit: minimum leaving water temperature for cooling operation.

■ [9-04] Overshoot setting: deﬁnes how much the water temperature may rise above the set point before the compressor stops. This function is only applicable in heating mode.

[A] Quiet mode

This ﬁeld setting allows to select the desired quiet mode. Two quiet modes are available: quiet mode A and quiet mode B.

In quiet mode A, priority is given to the unit operating quietly under all circumstances. Fan and compressor speed (and thus performance) will be limited to a certain percentage of the speed at normal operation. In certain cases, this might result in reduced performance.

In quiet mode B, quiet operation might be overridden when higher performance is required. In certain cases, this might result in less quiet operation of the unit to meet the requested performance.

■ [A-00] Quiet mode type: deﬁnes whether quiet mode A (0) or quiet mode B (2) is selected.

■ [A-01] Parameter 01: do not change this setting. Leave it set to its default value.

NOTE

Do not set other values than the ones mentioned.

■ [C-04] Bivalent hysteresis: deﬁnes the temperature difference between bivalent ON temperature and bivalent OFF temperature.

Bivalent operation

Applies only to installations with an auxiliary boiler (alternating operation, parallel connected). The purpose of this function is to determine —based on the outdoor temperature— which heating source can/will provide the space heating, either the Daikin unit or an auxiliary boiler.

The ﬁeld setting "bivalent operation" apply only the unit space heating operation and the permission signal for the auxiliary boiler.

When the "bivalent operation" function is enabled, the unit will stop automatically in space heating operation when the outdoor temperature drops below "bivalent ON temperature" and the permission signal for the auxiliary boiler becomes active.

When the bivalent operation function is disabled, the space heating by unit is possible at all outdoor temperatures (see operation ranges) and permission signal for auxiliary boiler is always disactivated.

■ [C-02] Bivalent operation status: deﬁnes whether bivalent operation is enabled (1) or disabled (0).

■ [C-03] Bivalent ON temperature: deﬁnes the outdoor temperature below which the permission signal for the auxiliary boiler will be active (closed, KCR on EKRP1HB) and space heating by indoor unit will be stopped.

■ In case the unit is single phase, the combination of setting [4-03]=0/2 with bivalent operation at low outdoor temperature can result in domestic hot water shortage.

■ The bivalent operation function has no impact on the domestic water heating mode. The domestic hot water is still and only heated by the 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 disactivated. See ﬁgure for the schematic location of this contact.

Installation manual

TEST RUN AND FINAL CHECK

Test run operation (manual)

The installer is obliged to verify correct operation of unit after installation.

Final check

Before switching on the unit, read following recommendations:

■ When the complete installation and all necessary settings have been carried out, close all front panels of the unit and reﬁt the unit cover.

■ The service panel of the switch box may only be opened by a licensed electrician for maintenance purposes.

DANGER

Never leave the unit unattended during installation or servicing. When the service panel is removed live parts can be easily touched by accident..

NOTE

Note that during the ﬁrst running period of the unit, required power input may be higher than stated on the nameplate of the unit. This phenomenon originates from the compressor that needs elapse of a 50 hours run in period before reaching smooth operation and stable power consumption.

Pre-run checks

Items to check

Electrical wiring Inter-unit wiring Earth wire

■ Is the wiring as mentioned on the wiring diagram? Make sure no wiring has been forgotten and that there are no missing phases or reverse phases.

■ Is the unit properly earthed?

■ Is the wiring between units connected in series

correct?

■ Are any of the wiring attachment screws loose?

■ Is the insulation resistance at least 1 MΩ?

- Use a 500 V mega-tester when measuring

insulation.

- Do not use a mega-tester for low-voltage circuits.

Automatic test run

When the unit is put into operation (by pressing the y button) for the ﬁrst time, the system will automatically perform a test run in cooling mode. The test run will take up to 3 minutes, during which no speciﬁc indication is given on the user interface.

During the automatic test run, it is important to ensure that the water temperature does not drop below 10°C, which might activate the freeze-up protection and thereby prevent the test run to ﬁnish. Should the water temperature drop below 10°C, press the h/c button so the h icon is displayed. This will activate the backup heater during the automatic test run and raise the water temperature sufﬁciently.

If the automatic test run has ended successfully, the system will automatically resume normal operation.

If there are misconnections or malfunctions, an error code will be displayed on the user interface. To resolve the error codes, see "Error

codes" on page 42.

If required, the installer can perform a manual test run operation at any time to check correct operation of heating, cooling and domestic water heating.

Procedure

1 Push the z button 4 times so the t icon will be displayed. 2 Depending on the unit model, heating operation, cooling

operation or both must be tested as follows (when no action is performed, the user interface will return to normal mode after 10 seconds or by pressing the z button once):

•To test the heating operation push the h/c button so the h icon is displayed. To start the test run operation press the y button.

•To test the cooling operation push the h/c button so the c icon is displayed. To start the test run operation press the y button.

•To test the domestic water heating operation push the v button. The test run operation will start without pressing the y button.

3 The test run operation will end automatically after 30 minutes or

when reaching the set temperature. The test run operation can be stopped manually by pressing the z button once. If there are misconnections or malfunctions, an error code will be displayed on the user interface. Otherwise, the user interface will return to normal operation.

4 To resolve the error codes, see "Error codes" on page 42.

To display the last resolved error code, push the z button 1 time. Push the z button again 4 times to return to normal mode.

NOTE

It is not possible to perform a test run if a forced operation from the unit is in progress. Should forced operation be started during a test run, the test run will be aborted.

■ Never leave the unit unattended with an open front panel during test run.

■ To protect the compressor, make sure to turn on the power supply 6 hours before starting operation.

NOTE

When the unit is put into pump down operation, the automatic test run ﬂag will be cleared. The next time the system is put into operation, the automatic test run will be executed again.

After ﬁnishing automatic test run or power ON/OFF, the compressor will operate in the selected operation mode and continue for certain time (set point on the remote controller is overruled during this operation).

MAINTENANCE AND SERVICE

In order to ensure optimal availability of the unit, a number of checks and inspections on the unit and the ﬁeld wiring have to be carried out at regular intervals.

This maintenance has to be carried out by your local Daikin technician.

DANGER: ELECTRIC SHOCK

■ Before carrying out any maintenance or repair activity, always switch off the circuit breaker on the supply panel, remove the fuses (or switch off the circuit breakers) or open protection devices of the unit.

■ Make sure that before starting any maintenance or repair activity, also the power supply to the outdoor unit is switched off.

■ Do not touch live parts for 10 minutes after the power supply is turned off because of high voltage risk.

■ The heater of the compressor may operate even in stop mode.

■ Please note that some sections of the electric component box are hot.

■ In order to prevent damage to the PCB, ﬁrst eliminate static electricity by touching a metal part (e.g. stop valve) with your hand. Then pull out the connector.

■ After measuring the residual voltage, pull out the outdoor fan connector.

■ Make sure you do not touch a conductive section.

■ The outdoor fan may rotate due to strong backblow

wind, causing the capacitor to charge. This may result in an electric shock.

■ Make sure you do not touch a conductive section.

■ Do not rinse the unit. This may cause electric shocks

or ﬁre.

■ When service panels are removed, live parts can be easily touched by accident. Never leave the unit unattended during installation or servicing when service panel is removed.

After maintenance, make sure the outdoor fan connector is connected again. Otherwise, the unit may break down.

Play it safe!

Touch a metal part by hand (such as the stop valve) in order to eliminate static electricity and to protect the PCB before performing service.

DANGER

Do not touch water pipes during and immediately after operation as the pipes may be hot. Your hand may suffer burns. To avoid injury, give the piping time to return to normal temperature or be sure to wear proper gloves.

WARNING

■ Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant ﬂowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

■ Do not touch the internal parts (pump, backup heater, etc.) during and immediately after operation.

Your hands may suffer burns if you touch the internal parts. To avoid injury, give the internal parts time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

The described checks must be executed at least once a year by qualiﬁed personnel.

1 Water pressure

Check if the water pressure is above 1 bar. If necessary add water.

2 Water ﬁlter

Clean the water ﬁlter.

3 Water pressure relief valve

Check for correct operation of the pressure relief valve by turning the red knob on the valve counter-clockwise:

■ If you do not hear a clacking sound, contact your local dealer.

■ In case the water keeps running out of the unit, close both

the water inlet and outlet shut-off valves ﬁrst and then contact your local dealer.

4 Pressure relief valve hose

Check that the pressure relief valve hose is positioned appropriately to drain the water.

5 Backup heater vessel insulation cover

Check that the backup heater insulation cover is fastened tightly around the backup heater vessel.

6 Domestic hot water tank pressure relief valve (ﬁeld supply)

Applies only to installations with a domestic hot water tank. Check for correct operation of the pressure relief valve on the

domestic hot water tank.

7 Domestic hot water tank booster heater

Applies only to installations with a domestic hot water tank. It is advisable to remove lime buildup on the booster heater to

extend its life span, especially in regions with hard water. To do so, drain the domestic hot water tank, remove the booster heater from the domestic hot water tank and immerse in a bucket (or similar) with lime-removing product for 24 hours.

8 Unit switch box

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

■ Check for correct operation of contactors K1M, K3M, K5M (applications with domestic hot water tank only) and K4M by use of an ohm meter. All contacts of these contactors must be in open position.

Installation manual

9 In case of use of glycol

(Refer to Caution: "Use of glycol" on page 16) Document the glycol concentration and the pH-value in the

system at least once a year.

■ A pH-value below 8.0 indicates that a signiﬁcant portion of the inhibitor has been depleted and that more inhibitor needs to be added.

■ When the pH-value is below 7.0 then oxidation of the glycol occurred, the system should be drained and ﬂushed thoroughly before severe damage occurs.

Make sure that the disposal of the glycol solution is done in accordance with relevant local laws and regulations.

TROUBLESHOOTING

This section provides useful information for diagnosing and correcting certain troubles which may occur in the unit.

This troubleshooting and related corrective actions may only be carried out by your local Daikin technician.

General guidelines

Before starting the troubleshooting procedure, carry out a thorough visual inspection of the unit and look for obvious defects such as loose connections or defective wiring.

General symptoms

Symptom 1: The unit is turned on (y LED is lit) but the unit is not heating or cooling as expected

POSSIBLE CAUSES CORRECTIVE ACTION

The temperature setting is not correct.

The water ﬂow is too low.

The water volume in the installation is too low.

Symptom 2: The unit is turned on but the compressor is not starting (space heating or domestic water heating)

Check the controller set point.

• Check that all shut off valves of the water circuit are completely open.

• Check if the water ﬁlter needs cleaning.

• Make sure there is no air in the system (purge air).

• Check on the manometer that there is sufﬁcient water pressure. The water pressure must be >1 bar (water is cold).

• Check that the pump speed setting is on the highest speed.

• Make sure that the expansion vessel is not broken.

• Check that the resistance in the water circuit is not too high for the pump (refer to "Setting the pump

speed" on page 27).

Make sure that the water volume in the installation is above the minimum required value (refer to "Checking

the water volume and expansion vessel pre-pressure" on page 14).

DANGER

When carrying out an inspection on the switch box of the unit, always make sure that the main switch of the unit is switched off.

When a safety device was activated, stop the unit and ﬁnd out why the safety device was activated before resetting it. Under no circumstances safety devices may be bridged or changed to a value other than the factory setting. If the cause of the problem cannot be found, call your local dealer.

If the pressure relief valve is not working correctly and is to be replaced, always reconnect the ﬂexible hose attached to the pressure relief valve, to avoid water dripping out of the unit!

NOTE

For problems related to the optional solar kit for domestic water heating, refer to the troubleshooting in the installation manual of that kit.

POSSIBLE CAUSES CORRECTIVE ACTION

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

The beneﬁt kWh rate power supply settings and electrical connections do not match.

The beneﬁt kWh rate signal was sent by the electricity company.

Symptom 3: Pump is making noise (cavitation)

POSSIBLE CAUSES CORRECTIVE ACTION There is air in the system. Purge air. Water pressure at pump inlet is too

low.

In case of low water temperature, the system utilizes the backup heater to reach the minimum water temperature ﬁrst (15°C).

• Check that the backup heater power supply is correct.

• Check that the backup heater thermal fuse is closed.

• Check that the backup heater thermal protector is not activated.

• Check that the backup heater contactors are not broken.

If [D-01]=1 or 2, the wiring requires speciﬁc installation like illustrated in

"Connection to a beneﬁt kWh rate power supply" on page 23. Other

correctly installed conﬁgurations are possible, but are to be speciﬁc for the type of beneﬁt kWh rate power supply type at this speciﬁc site.

Wait for the power to return.

• Check on the manometer that there is sufﬁcient water pressure. The water pressure must be >1 bar (water is cold).

• Check that the manometer is not broken.

• Check that the expansion vessel is not broken.

• Check that the setting of the prepressure of the expansion vessel is correct (refer to "Setting the pre-

pressure of the expansion vessel" on page 15).

Symptom 7: Space heating capacity shortage at low outdoor temperatures

POSSIBLE CAUSES CORRECTIVE ACTION

Backup heater operation is not activated.

Check that the "backup heater operation status" ﬁeld setting [4-00] is turned on, see "Field settings" on

page 28.

Check whether or not the thermal protector of the backup heater has been activated (refer to Main

components, "Backup heater thermal protector" on page 13 for

location of the reset button). Check if booster heater and backup heater are conﬁgured to operate simultaneously (ﬁeld setting [4-01], see "Field settings" on page 28) Check whether or not the thermal fuse of the backup heater is blown (refer to "Main components",

"Backup heater thermal fuse" on page 13 for location of the reset

button).

The backup heater equilibrium temperature has not been conﬁgured correctly.

Too much heat pump capacity is used for heating domestic hot water (applies only to installations with a domestic hot water tank).

Raise the ﬁeld setting [5-01] to activate backup heater operation at a higher outdoor temperature.

Check that the temperature conﬁgured appropriately:

• Make sure that the 'space heating

• Raise the 'space heating priority
