WARNING

■ 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.

CAUTION

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

3. INTRODUCTION

3.1. General information

Thank you for purchasing this product. This unit is used for both heating and cooling applications. The unit

can be combined with Daikin fan coil units, ﬂoor heating applications, low temperature radiators, domestic hot water tank (option) and Daikin solar kit (option).

A remote controller is standard supplied with the unit to control your installation.

Heating/cooling units and heating only units

The unit range consists of two main versions: a heating/cooling (EB) version and a heating only (ED) version.

Nordic units

EDL and EBL units include special equipment (insulation, heater sheet,...) to ensure good operation in areas where low ambient temperature can occur together with high humidity conditions. In such conditions the EDH and EBH models may experience problems with severe ice build up on the air-cooled coil. In case such conditions are expected, the EDL or EBL must be installed instead. These models contain countermeasures (insulation, heater sheet,...) to prevent freeze up.

■ Possible options

Heater sheet Drain socket

EDLQ, EBLQ Standard Use prohibited EDHQ, EBHQ Optional kit

(a) Combination of both options is prohibited.

The units are delivered with an integrated backup heater for additional heating capacity during low 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.

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 7.

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 unit). See "Field wiring conﬁguration B" on

page 8.

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.

CAUTION

■ Be sure that the boiler and the integration of the boiler in the system is in accordance with the applicable legislation.

■ Always install a 3-way valve, even if no domestic hot water tank is installed. This to ensure that the freeze protection function (see "Freeze protection function"

on page 35) can operate when the boiler is active.

Operation

■ Conﬁguration A

When the room thermostat requests heating, either the E(D/B)* unit or the boiler starts operating, depending on the position of the auxiliary contact (A).

■ Conﬁguration B

When the room thermostat requests heating, either the E(D/B)* unit or the boiler starts operating, depending on the outdoor temperature (status of "permission signal for the auxiliary boiler").

When the permission is given towards the boiler, the space heating operation by the E(D/B)* unit will be automatically switched off.

For more details see ﬁeld setting [C-02~C-04].

NOTICE

■ 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 unit’s air thermistor, make sure to install the 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.

NOTICE

Make sure to conﬁgure the DIP switch SS2-3 on the PCB of the E(D/B)* switch box correctly. Refer to "10.2. Room

thermostat installation conﬁguration" on page 29.

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

operation" on page 41.

NOTICE

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

(a)

valve in the return water ﬂow of

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 EKRTR or EKRTW

are 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.

INFORMATION

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.

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 achieve 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.

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 unit, the pump (4) will operate when there is a request for heating from T1 and/or T2. The unit will start operating to achieve the target leaving water temperature. The target leaving water temperature depends on which room thermostat is requesting heating.

Set point Field setting Thermo status

Zone A First UI ON OFF ON OFF Zone B Second [7-03] OFF ON ON OFF Resulting water temperature UI [7-03] [7-03] — Result pump operation ON ON ON OFF

When the room temperature of both zones is above the thermostat set point, the unit and pump will stop operating.

NOTICE

■ Make sure to connect the thermostat wires to the correct terminals (see "5. Overview of the unit" on

page 10).

■ Make sure to conﬁgure the ﬁeld settings [7-02], [7-03] and [7-04] correctly. Refer to "Dual set point control"

on page 39.

■ Make sure to conﬁgure the DIP switch SS2-3 on the PCB of the switch box correctly. Refer to "10.2. Room

thermostat installation conﬁguration" on page 29.

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

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

INFORMATION

■ 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.

■ The hydraulic balance is very important. (unit - mixing station - FCU1...3)

INFORMATION

■ 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

■ 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.

■ At this type of application heating/cooling selection always has to be done on the user interface. Refer to

"Dual set point control" on page 39 for more details.

General

1 Select an installation site where the following conditions are

satisﬁed and that meets with your customer's approval.

- Places which are well-ventilated.

- Places where the unit does not bother next-door neighbours.

- Safe places which can withstand the unit's weight and vibration and where the unit can be installed level.

- Places where servicing space can be well ensured.

- Places where the units' piping and wiring lengths come within the allowable ranges.

- Places where water leaking from the unit cannot cause damage to the location (e.g. in case of a blocked drain pipe).

- Places where the rain can be avoided as much as possible.

- Do not install the unit in places often used as workplace. In case of construction works (e.g. grinding works) where a

lot of dust is created, the unit must be covered.

- Do not place any objects or equipment on top of the unit (top plate)

- Do not climb, sit or stand on top of the unit.

- All piping lengths and distances have been taken into consideration.

Requirement Value

Maximum allowable distance between the domestic hot water tank and the unit (only for installations with domestic hot water tank). The thermistor cable supplied with the domestic hot water tank is 12 m in length. In order to optimise efﬁciency Daikin recommends to install the 3-way valve and the domestic hot water tank as close as possible to the unit.

2 When installing the unit in a place exposed to strong wind, pay

special attention to the following. Strong winds of 5 m/sec or more blowing against the unit's air

outlet causes short circuit (suction of discharge air), and this may have the following consequences:

- deterioration of the operational capacity,

- frequent frost acceleration in heating operation,

- disruption of operation due to rise of high pressure,

- when a strong wind blows continuously on the face of the unit, the fan can start rotating very fast until it breaks.

Refer to the ﬁgures for installation of this unit in a place where the wind direction can be foreseen.

■ Tu rn the air outlet side toward the building's wall, fence or screen.

3 Prepare a water drainage channel around the foundation, to

drain waste water from around the unit.

4 If the water drainage of the unit is not easy, please build up the

unit on a foundation of concrete blocks, etc. (the height of the foundation should be maximum 150 mm).

5 If you install the unit on a frame, please install a waterproof plate

within 150 mm of the underside of the unit in order to prevent the invasion of water from the lower direction.

6 When installing the unit in a place frequently exposed to snow,

pay special attention to elevate the foundation as high as possible.

7 If you install the unit on a building frame,

please install a waterproof plate (ﬁeld supply) (within 150 mm of the underside of the unit) in order to avoid the drainwater dripping. (See ﬁgure).

Selecting a location in cold climates

NOTICE

When operating the unit in a low outdoor ambient temperature, be sure to follow the instructions described below.

■ To prevent exposure to wind, install the unit with its suction side facing the wall.

■ Never install the unit at a site where the suction side may be exposed directly to wind.

■ To prevent exposure to wind, install a bafﬂe plate on the air discharge side of the unit.

■ In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit and to set the outlet side at a right angle to the direction of the wind:

Make sure there is enough room to do the installation

■ Set the outlet side at a right angle to the direction of the wind.

the applicable tank type. See ﬁeld settings in "[4] Backup/booster heater

operation and space heating off temperature" on page 34 for more details.

(2) For tank without electrical booster heater (EKHTS), the backup heater will

be used in domestic water heating mode.

(3) Only applicable for tank with built-in electrical booster heater (EKHW*).

Installation manual

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

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

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 sealant 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.

■ Select piping diameter in relation to required water ﬂow and available external static pressure 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 unit will be stopped.

■ 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. It is very important 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 maximum change over time of the valve shall be less than 60 seconds.

NOTICE

It is strongly recommended to install an additional ﬁlter on the heating water circuit. Especially to remove metallic particles from the ﬁeld heating piping, it is advised to use a magnetic or cyclone ﬁlter which can remove small particles. Small particles can damage the unit and will not be removed by the standard ﬁlter of the heat pump unit.

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

"14. Technical speciﬁcations" on page 54 to know the internal

water volume of the unit.

INFORMATION

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.

Calculating the pre-pressure of the expansion vessel

The pre-pressure (Pg) to be set depends on the maximum installation height difference (H) and is calculated as below:

Pg=(H/10+0.3) bar

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.

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 (no glycol used) 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: Pg=(H/10+0.3) bar=(0/10+0.3) bar=0.3 bar

■ 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 an installer.

Connecting the water circuit

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

NOTICE

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.

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 19.

Refer to "Freeze protection function" on page 35. 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%

WARNING ETHYLENE GLYCOL IS TOXIC

INFORMATION

(a)

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

(b)

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

on page 18.

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 the applicable legislation.

■ 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.

(a)(b)

NOTICE

For Australia and New Zealand only:

If a hot water tank is connected to this unit and an antifreeze solution is added to the water circuit, the antifreeze additive must be non-toxic and coloured with a dye at a concentration level high enough that any leakage into the potable water is easily discernible.

Materials approved by Food Standards Australia New Zealand are acceptable.

NOTICE 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 the applicable legislation 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.

INFORMATION

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.

Also refer to "Checks before initial start-up" on page 30.

NOTICE

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

9. ELECTRICAL WIRING WORK

1 Connect the water supply to a drain and ﬁll valve (see "5.2. Main

components" on page 10).

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.

INFORMATION

■ 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 EU directive 98/83 EC.

NOTICE

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.

■ Never squeeze bundled cables. Secure the electrical wiring with cable ties as shown in ﬁgure 2 so that it does not come into contact with the piping (particularly on the high-pressure side) or sharp edges. Make sure no external pressure is applied to the terminal connections.

■ Power supply wires must be attached securely.

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

equipment will break down.

■ 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 an earth leakage circuit breaker in accordance with the applicable legislation. Failure to do so may cause electric shock or ﬁre.

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

" and the equipment

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.

■ 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 highfrequency waves. Therefore, never install a phase advancing capacitor.

■ Be sure to use a dedicated power circuit; never use a power supply shared by another appliance.

■ Be sure to install the required fuses or circuit breakers.

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 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 unit is still possible. The controller, the expansion vessel heater, plate heat exchanger heater and switch box heater have power supply and the freeze protection function can operate when required.

■ 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, ...).

■ If the beneﬁt kWh rate is active for more than 2 hours, backup heater operation can be required (part of the freeze protection function, see "Protecting the water

circuit against freezing" on page 19). For this reason,

the backup heater shall be connected to a normal kWh rate power supply and the correct setting [d-00] must be selected. See "[d] Beneﬁt kWh rate power

supply/Local shift value weather dependent" on page 42.

For a beneﬁt kWh rate power supply like illustrated below as types 2 or 3

If during beneﬁt kWh rate power supply, the main power supply is shut off, and the normal kWh rate power supply is not connected to 1-2, X11M (only allowed for EDL and EBL models) then:

1. the expansion vessel heater, plate heat exchanger heater and switch box heater can not be controlled,

2. the controller display will be blank + after 2 hours, the real time clock of the controller will be reset,

3. the freeze protection function (refer to "Freeze

protection function" on page 35) can not operate.

To overcome 1, 2 and 3 the unit should be connected to a normal kWh rate power supply via 1-2 X11M to allow continuous control and operation (e.g., pump, expansion vessel heater, plate heat exchanger heater, switch box heater, and freeze protection function).

The power supply (compressor compartment, X1M: L1, L2, L3, N) interruption may not be longer than 2 hours to guarantee to optimized startup condition for compressor.

10.7. Powering up the unit

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.

10.8. Setting the pump speed

The pump speed can be selected on the pump (see "5.2. Main

components" on page 10).

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).

INFORMATION

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.

10.9. 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.

■ 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, " 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.

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).

INFORMATION

If the booster heater operation is limited ([4-03]=0) and the ambient temperature T

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

The operation of the backup heater can altogether be enabled, disabled, or limited.

■ [4-00] Status: deﬁnes whether backup heater operation is disabled (0), enabled (1) or limited (2).

When [4-00]=2, the backup heater is only allowed during domestic water heating mode.

INFORMATION

■ In special conditions, for example the unit cannot work due to malfunction, the backup heater will also be allowed to operate during space heating.

■ If the backup heater operation is disabled ([4-00]=0), the domestic water will not be heated.

CAUTION

For optional domestic hot water tank EKHTS, the ﬁeld setting [4-03] shall be 5.

[4-03]=5, this setting is automatically selected if the EKHTS tank is connected and SS2-2 is set to ON. [4-03]=5 activate the applicable logic and ﬁeld settings for EKHTS.

INFORMATION

■ Make sure that the domestic hot water set point is according to your requirements.

Start with a low domestic hot water set point, and only increase if you feel that the domestic hot water supply temperature is not sufﬁcient for your requirements (this depends on your water using pattern).

■ Make sure the domestic water is not heated unnecessary.

Space heating off temperature

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

■ [4-06] Backup heater emergency operation: deﬁnes whether backup heater is allowed (1) or not allowed (0) during emergency operation.

Emergency operation will startup backup heater operation during certain unit malfunctions.

■ [4-07] Backup heater second step: deﬁnes whether backup heater second step is allowed (1) or not allowed (0).

In this way it is possible to limit the backup heater capacity.

[5] Equilibrium temperature and space heating priority temperature

Equilibrium temperature (only for EKHW*)

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 (only for EKHW*)

(1)

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.

INFORMATION

If the booster heater operation is limited ([4-03]=0) and the ambient temperature T

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.

■ [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.

Applies only to installations with a domestic hot water tank

. The domestic water is heated by heat pump and backup heater. The 'space heating priority temperature' ﬁeld settings apply to operation of the 3-way valve and the backup heater during domestic hot water operation.

When the space heating priority function is enabled, it is assured that the full capacity of the heat pump is used as much as possible for space heating when the outdoor temperature equals or drops below the speciﬁed space heating priority temperature, i.e. low outdoor temperature. This is done by allowing the backup heater to assist during domestic hot water heating. This means the heating up time of domestic water heating will be kept to a minimum and as much as possible capacity of the heat pump is used for space heating.

■ [5-02] Space heating priority temperature: outdoor temperature below which the domestic water heat up time is reduced to a minimum, as the backup heater will additionally assist during low domestic hot water tank temperature situations (this ﬁeld setting is ﬁxed and can not be modiﬁed).

■ [5-03] Space heating priority temperature: outdoor temperature below which the backup heater is allowed to assist during domestic hot water heating. This means the heating up time of domestic water heating will be kept to a minimum and as much as possible capacity of the heat pump is used for space heating.

NOTICE

[5-01] Equilibrium temperature and [5-03] Space heating priority temperature are ﬁeld settings that are related to backup heater. So it is obliged to set [5-01] and [5-03] to the same setting value.

INFORMATION

If the backup heater operation is limited ([4-00]=0) and the ambient temperature T

is lower than the ﬁeld

setting to which parameter [5-03] is set, then the domestic hot water will not be heated with the backup heater.

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

DT for booster heater (only for EKHW*)

(1)

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.

INFORMATION

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.

WARNING

Be aware that the domestic hot water temperature will be automatically increased (always) with the value selected in ﬁeld setting [7-00] compared 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 domestic hot water temperature can be a potential risk for human injuries, a mixing valve (ﬁeld supply) shall be installed at the hot water outlet connection of the domestic hot water tank. This mixing valve shall secure that the hot water temperature at the hot water tap never rise above a set maximum value. This maximum allowable hot water temperature shall be selected according to the applicable legislation.

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

■ The second set point cooling [7-04] is always a ﬁxed value. It should be linked to the heat emitters which require the lowest set point in cooling mode. Example: fan coil units.

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

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

■ 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 setting 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 variate between [8-01] and [8-01]+[8-04] depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 40.

INFORMATION

Note that when the unit is conﬁgured to work with a room thermostat (refer to "10.2. Room thermostat

installation conﬁguration" on page 29), the

maximum running timer will only be taken into account when there is a request for space heating or space cooling. When there is no request for space heating or space cooling, domestic water heating by the heat pump will continue until the 'heat pump OFF temperature' (see ﬁeld settings

"[6]" on page 37) 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 variate between [8-02] and 0 depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 40.

INFORMATION

When dual set point control is enabled, heating/cooling selection always has to be done on the user interface.

NOTICE

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).

INFORMATION

■ 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]=0/2/3/4 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].

■ Remark that the b icon will be ﬂashing during setback operation. The calculated leaving water setback set point is not shown during setback operation.

■ By default the setback function is disabled.

■ The setback function can be combined with the

automatic weather dependent set point operation.

■ Setback function is an automatic daily scheduled function.

■ The setback function can be combined with the schedule timer. When setback is active, the scheduled space heating set point will be lowered with the [9-08] leaving water setback value.

■ [9-05] Deﬁnes whether the setback function is turned ON (1) or OFF (0)

In case the EKHW* is installed and [4-03]=4 or the EKHTS tank is installed, it is advised to set the start time of automatic storage during night [6-04] on the moment that the setback function starts [9-06].

INFORMATION

Pay attention not to set the setback value too low, especially during colder periods (e.g. winter time). It is possible that the room temperature can not be reached (or it will take a much longer time) because of the big temperature difference.

[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.

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" applies only to 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 unit will be stopped.

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

INFORMATION

■ In case the outdoor unit is not single phase (W1), 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.

11. TEST RUN AND FINAL CHECK

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

11.1. Final check

Before switching on the unit, read the following recommendations:

■ When the complete installation and all necessary settings have been carried out, be sure that all panels of the unit are closed. If this is not the case, inserting your hand through the remaining openings can cause serious injury due to electrical and hot parts inside the unit.

■ 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.

INFORMATION

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.

11.2. Pre-run checks

Items to check

Electrical wiring Inter-unit wiring Earth wire

11.3. 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

"13.3. Error codes" on page 53.

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

NOTICE

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).

11.4. Test run operation (manual)

If required, the installer can perform a manual test run operation at any time to check correct operation of cooling, heating 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 "13.3. Error codes" on page 53.

INFORMATION

■ 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.

■ 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.

DANGER

■ 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.

12. 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 shall be carried out by the installer or service agent.

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 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.

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

■ Make sure you do not touch a conductive section.

■ The fan may rotate due to strong backblow wind,

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

■ 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 fan connector is connected again. Otherwise, the unit may break down.

" when

pressing certain buttons

POSSIBLE CAUSES CORRECTIVE ACTION

The current permission level is set to a level that prevents using the pressed button.

Change the "user permission level" ﬁeld setting [0-00], see "10.10. Field

settings" on page 32.

Symptom 7: Space heating capacity shortage at low outdoor temperatures

POSSIBLE CAUSES CORRECTIVE ACTION

Backup heater operation is not activated.

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).

Check that the "backup heater operation status" ﬁeld setting [4-00] is turned on, see "10.10. Field

settings" on page 32.

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

components, "16. Backup heater thermal protector" on page 11 for

location of the reset button). Check if booster heater and backup heater are conﬁgured to operate simultaneously (ﬁeld setting [4-01], see "10.10. Field settings" on

page 32).

Check whether or not the thermal fuse of the backup heater is blown (refer to "Main components",

"17. Backup heater thermal fuse" on page 11 for location of the reset

button). Raise the

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

Check that the temperature' ﬁeld settings are conﬁgured appropriately:

'equilibrium temperature'

'space heating priority

• Make sure that the 'space heating priority status' ﬁeld setting [5-02] is enabled.

• Raise the 'space heating priority temperature' ﬁeld setting [5-03] to activate booster heater operation at a higher outdoor temperature.

Symptom 8: [4-03] and maximum tank set point is not according to the the applicable tank

1. In case of domstic hot water tank with built-in electrical booster

heater (EKHW*) and [4-03]=5 or maximum domestic hot water set point is 60°C, the wrong ﬁeld setting and logic is activated according to the applicable tank.

2. In case of domestic hot water tank without booster heater (EKHTS) and [4-03]≠5 or maximum domestic hot water set point is 78°C, the wrong ﬁeld setting and logic is activated according to the applicable tank.

POSSIBLE CAUSES CORRECTIVE ACTION

At the time of setting DIP switch SS2-2, wrong ﬁeld wiring caused wrong detection of tank type.

Check all ﬁeld wiring between unit and tank switch box.

Reset procedure

•Power off the unit and put SS-2 to OFF.

•Power on the unit, it means that the unit will detect no domestic hot water tank.

•Power off the unit and put SS2-2 to ON again.

•Power on the unit and the unit will detect again the type of tank: tank with built-in electrical booster heater (EKHW*)([4-03] default value will be 3), or tank without electrical booster heater (EKHTS)([4-03] default value will be 5).

Symptom 9: Temperature values displayed on the remote controller (user interface) are displayed in °F instead of °C

POSSIBLE CAUSES CORRECTIVE ACTIONS

You accidentally changed the setting to view the temperature values in °F by pushing the ib and jb buttons simultaneously.

To change the display back to °C, push ib and jb buttons simultaneously for 5 seconds. Execute same procedure to change back to the °F display. The default temperature display is in °C.
