    Space heating with an auxiliary boiler (alternating operation)Space heating application by either the Daikin indoor unit or by anauxiliary boiler connected in the system. The decision whether eitherthe EKHV* indoor unit or the boiler will operate can be achieved by anauxiliary contact or an EKHV* 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 conguration A" on page 6.The EKHV* indoor unit controlled contact (also called 'permissionsignal for the auxiliary boiler") is determined by the outdoortemperature (thermistor located at the outdoor unit). See "Field wiringconguration B" on page 6.Bivalent operation is only possible for space heating operation, notfor the domestic water heating operation. Domestic hot water in suchan application is always provided by the domestic hot water tankwhich is connected to the Daikin indoor unit.

    When the room thermostat requests heating, either the EKHV*unit or the boiler starts operating, depending on the position ofthe auxiliary contact (A).

    Conguration BWhen the room thermostat requests heating, either the EKHV*unit or the boiler starts operating, depending on the outdoortemperature (status of "permission signal for the auxiliaryboiler").When the permission is given towards the boiler, the spaceheating operation by the EKHV* unit will be automaticallyswitched off.For more details see eld setting [C-02~C-04].

    NOTICE Conguration A

    Make sure that auxiliary contact (A) has sufcientdifferential or time delay so as to avoid frequentchangeover between the EKHV* unit and the boiler. Ifthe auxiliary contact (A) is an outdoor temperaturethermostat, make sure to install the thermostat in theshade, so that it is not inuenced or turned ON/OFFby the sun.Conguration BMake sure that the bivalent hysteresis [C-04] hassufcient differential to avoid frequent changeoverbetween the EKHV* unit and the boiler. As theoutdoor temperature is measured via the outdoor unit,air thermistor make sure to install the outdoor unit inthe shade, so that it is not inuenced by the sun.Frequent switching may cause corrosion of the boilerin an early stage. Contact the manufacturer of theboiler.

    During heating operation of the EKHV* unit, the unitwill operate so as to achieve the target leaving watertemperature as set on the user interface. Whenweather dependent operation is active, the watertemperature is determined automatically dependingon the outdoor temperature.During heating operation of the boiler, the boiler willoperate so as to achieve the target leaving watertemperature as set on the boiler controller.Never set the target leaving water temperature setpoint on the boiler controller above 55C.

    Make sure to only have 1 expansion vessel in thewater circuit. An expansion vessel is alreadypremounted in the Daikin indoor unit.

    NOTICEMake sure to congure the DIP switch SS2-3 on the PCBof the EKHV* switchbox correctly. Refer to "8.2. Roomthermostat installation conguration" on page 24.For conguration B: Make sure to congure the eldsettings [C-02, C-03 and C-04] correctly. Refer to "Bivalentoperation [C-02]=1" on page 32.

    Make sure that return water to the EKHV* heat exchangernever exceeds 55C.For this reason, never put the target leaving watertemperature set point on the boiler controller above 55Cand install an aquastat(a) valve in the return water ow ofthe EKHV* unit.Make sure that the non-return valves (eld supply) arecorrectly installed in the system.Make sure that the room thermostat (th) is not frequentlyturned ON/OFF.Daikin shall not be held liable for any damage resultingfrom failure to observe this rule.

    (a) The aquastat valve must be set for 55C and must operate to close the return water ow to the unit when the measured temperature exceeds 55C. When the temperature drops to a lower level, the aquastat valve must operate to open the return water ow to the EKHV* unit again.

    Manual permission towards the EKHV* unit on the boiler.In case only the EKHV* unit should operate in spaceheating mode, disable the bivalent operation via setting[C-02].In case only the boiler should operate in space heatingmode, increase the bivalent ON temperature [C-03] to25C.

    Space heating with room thermostat application through oor heatingloops and fan coil units. The oor heating loops and fan coil unitsrequire different operating water temperatures.The oor heating loops require a lower water temperature in heatingmode compared to fan coil units. To achive these two set points, amixing station is used to adapt the water temperature according torequirements of the oor heating loops. The fan coil units are directlyconnected to the indoor unit water circuit and the oor heating loopsafter the mixing station. The control of this mixing station is not doneby the indoor unit.The operation and conguration of the eld water circuit is theresponsibility of the installer.Daikin only offers a dual set point control function. By this functiontwo set points can be generated. Depending on the required watertemperature (oor heating loops and/or fan coil units are required)rst set point or second set point can be activated.

    When the room thermostat for the oor heating loop (T1) and the fancoil units (T2) are connected to the indoor unit, the pump (4) willoperate when there is a request for heating from T1 and/or T2. Theoutdoor unit will start operating to achieve the target leaving watertemperature. The target leaving water temperature depends on whichroom thermostat is requesting heating.

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

    The advantage of the dual set point control is that the heatpump will/can operate at the lowest required leaving watertemperature when only oor heating is required. Higherleaving water temperatures are only required in case fancoil units are operating.This results in a better performance of the heat pump.

    For all guidelines, instructions and specications regardingrefrigerant piping work between the indoor unit and the outdoor unit,please refer to the outdoor unit installation manual.

    Guidelines for are connection

    Flares should not be re-used. New ones should be made inorder to prevent leaks.

    Use a pipe cutter and are tool suitable for the refrigerant used. Only use the annealed are nuts included with the unit. Using

    different are nuts may cause the refrigerant to leak. Please refer to the table for aring dimensions and tightening

    torques (too much tightening will result in splitting the are).

    When connecting the are nut, coat the are inner surface withether oil or ester oil and initially tighten 3 or 4 turns by handbefore tightening rmly.

    When loosening a are nut, always use two wrenches together. When connecting the piping, always use a spanner and torquewrench together to tighten the are nut to prevent are nutcracking and leaks.

    Not recommended, but in case of emergencyShould you be forced to connect the piping without a torquewrench, follow the following installation method: Tighten the are nut using a spanner until the tightening

    torque suddenly increases. From that position further tighten the are nut the angle listed

    below:

    6.6. Water Piping

    The unit is equipped with a water inlet and water outlet for connectionto a water circuit. This circuit must be provided by an installer andmust comply with the applicable legislation.

    6.7. General precautions concerning water circuit

    Before continuing the installation of the unit, check the followingpoints: The maximum water pressure is 4 bar. The maximum water temperature is 65C. Provide adequate safeguards in the water circuit to be sure that

    the water pressure will never exceed the maximum allowableworking pressure (4 bar).

    Shut-off valves from exible hoses delivered with the unit shouldbe installed so that normal servicing can be accomplishedwithout draining the system.

    Drain taps must be provided at all low points of the system topermit complete drainage of the circuit during maintenance orservice to the unit. A drain valve is provided in the unit to drainthe water from the unit water system.

    WARNINGInstallation shall be done by an installer, the choice ofmaterials and installation shall comply with the applicablelegislation. In Europe the EN378 is the applicable standardthat shall be used.

    Make sure to blow through with nitrogen whenbrazing.Blowing through with nitrogen prevents the creation oflarge quantities of oxidized lm on the inside of thepiping. An oxidized lm adversely affects valves andcompressors in the refrigerating system and preventsproper operation.

    The nitrogen pressure should be set to 0.02 MPa (i.e.,just enough so it can be felt on the skin) with apressure-reducing valve.

    Do not use anti-oxidants when brazing the pipe joints.Residue can clog pipes and break equipment.

    Do not use ux when brazing copper-to-copperrefrigerant piping. Use phosphor copper brazing lleralloy (BCuP) which does not require ux.

    Flux has an extremely harmful inuence on refrigerantpiping systems. For instance, if chlorine based ux isused, it will cause pipe corrosion or, in particular, if theux contains uorine, it will deteriorate the refrigerantoil.

    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. 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 causedamage to the pipes.

    Select piping diameter in relation to required water ow andavailable external static pressure of the pump.

    The minimum required water ow for the indoor unit operation is16 l/min. When the water ow is lower than this minimum value,ow error 7H will be displayed and the operation of the indoorunit will be stopped.

    Precautions when connecting eld piping and regardinginsulation

    The complete water circuit, inclusive all piping, must be insulated toprevent reduction of the heating capacity.If the indoor ambient temperature is higher than 30C and thehumidity is higher than RH 80% then the thickness of the insulationmaterials should be at least 20 mm in order to avoid condensation onthe surface of the insulation.

    WARNINGIt is strongly recommended to install an additional lter onthe heating water circuit. Especially to remove metallicparticles from the eld heating piping, it is advised to use amagnetic or cyclone lter which can remove smallparticles. Small particles can damage the unit and will notbe removed by the standard lter of the heat pump unit.

    NOTICE Consider carefully the installation location of the

    exible water inlet pipe. According to the direction of the water ow, the water

    lter must be positioned as shown in the gure.

    Provide sufcient space allowing easy access toclean the water lter and regular operation check ofthe safety valve.

    Provide a exible hose for pressure relief valve blow-off (eld supply).

    Consider to support the water inlet pipe and wateroutlet pipe so not to stress the eld piping.

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

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

    1 Check that the total water volume in the installation, excludingthe internal water volume of the indoor unit, is 20 l minimum.Refer to "Technical specications" on page 44 to know theinternal water volume of the indoor unit.

    volume in the installation is below the maximum allowed watervolume.

    6.8. Charging water

    Calculating the pre-pressure of the expansion vesselThe pre-pressure (Pg) to be set depends on the maximum installationheight difference (H) and is calculated as below:Pg=(H/10+0.3) bar

    In most applications this minimum water volume will have asatisfying result.In critical processes or in rooms with a high heat loadthough, extra water volume might be required.

    NOTICEWhen circulation in each space heating loop is controlledby remotely controlled valves, it is important that thisminimum water volume is kept even if all the valves areclosed.Example

    During lling, it might not be possible to remove all airin the system. Remaining air will be removed throughthe automatic air purge valves during rst operatinghours of the system. Additional lling with waterafterwards might be required.

    The water pressure indicated on the manometer willvary depending on the water temperature (higherpressure at higher water temperature).However, at all times water pressure shall remainabove 1 bar to avoid air entering the circuit.

    The unit might dispose some excessive water throughthe pressure relief valve.

    Water quality must be according to EU directive98/83 EC.

  • Checking the maximum allowed water volume Accessing the expansion vessel: Remove the front and left decoration panels, refer toEKHVH/X008BB6V3 + EKHVH/X008BB6+9WNDaikin Altherma indoor unit4PW64329-1 07.2010

    Installation manual17

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

    1 Determine for the calculated pre-pressure (Pg) thecorresponding maximum water volume using the graph below.

    2 Check that the total water volume in the entire water circuit islower than this value.

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

    Example 1The indoor unit is installed 5 m below the highest point in the watercircuit. The total water volume in the water circuit is 100 l.

    In this example, no action or adjustment is required.Example 2The indoor 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:

    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 sufces for the installation.Setting the pre-pressure of the expansion vesselWhen it is required to change the default pre-pressure of theexpansion 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-pressureshould only be adjusted by a licensed installer.
