3 About the units and options

3.1 About the indoor unitThis installation manual concerns the inverter heat pump chilling unitwith separate hydro module. The unit is intended for indoorinstallation and can be combined with VRV outdoor units(SERHQ020+032BAW1) for air conditioning purposes, or it can beused for supplying water for process cooling applications.

The units are available in 4 standard sizes with nominal capacitiesranging from 16.8 to 63 kW.

The unit is designed to work in heating mode at ambienttemperatures from –15°C to 35°C and in cooling mode at ambienttemperatures from –5°C to 43°C.

The main component is the water heat exchanger.

The indoor unit is connected to the outdoor unit by field refrigerantpiping and the compressor in the outdoor unit circulates refrigerantinto the heat exchangers.

▪ In cooling mode, the refrigerant transports the heat taken from thewater heat exchanger to the air heat exchanger where the heat isreleased to the air.

▪ In heating mode, the refrigerant transports the heat taken from theair heat exchanger to the water heat exchanger where the heat isreleased to the water.

4.2 Preparing water piping

4.2.1 Water circuit requirements

NOTICE

In case of plastic pipes, make sure they are fully oxygendiffusion tight according to DIN  4726. The diffusion ofoxygen into the piping can lead to excessive corrosion.

▪ Connecting piping – Legislation. Make all piping connections inaccordance with the applicable legislation and the instructions inthe "Installation" chapter, respecting the water inlet and outlet.

▪ Connecting piping – Force. Do NOT use excessive force whenconnecting the piping. Deformation of the piping can causemalfunctioning of the unit.

▪ Connecting piping – Tools. Only use appropriate tooling tohandle brass, which is a soft material. If NOT, pipes will getdamaged.

▪ Connecting piping – Air, moisture, dust. If air, moisture or dustgets into the circuit, problems may occur. To prevent this:

▪ Only use clean pipes

▪ Hold the pipe end downwards when removing burrs.

▪ Cover the pipe end when inserting it through a wall, to preventdust and/or particles entering the pipe.

▪ Use a decent thread sealant to seal connections.

Capacity class Minimum required flow rate20 23 l/min32 36 l/min40 46 l/min64 72 l/min

▪ Field supply components – Water pressure and temperature.Check that all components in the field piping can withstand thewater pressure and water temperature.

▪ Drainage – Low points. Provide drain taps at all low points of thesystem in order to allow complete drainage of the water circuit.

▪ Non-brass metallic piping. When using non-brass metallicpiping, insulate the brass and non-brass properly so that they doNOT make contact with each other. This to prevent galvaniccorrosion.

▪ Shut-off valves. Two shut-off valves are delivered with the unit.Install them as shown in the following figure.

b Shut-off valvec Bendd Filter

NOTICE

Before mounting the bend, attach the filter to it.

NOTICE

If the bend is not used during installation, replace it with anextension (5 cm long for a 1¼"  filter, and 6 cm long for a2" filter) to ensure proper cleaning operation of the filter.

NOTICE

Be sure to install the filter properly. Failure to install orincorrect installation will damage the plate heat exchangerpermanently.

▪ Drain taps. Drain taps must be provided at all low points of thesystem to permit complete drainage of the circuit. A drain valve isprovided inside the unit.

▪ Air vents. Provide air vents at all high points of the system, whichmust also be easily accessible for servicing. An automatic airpurge valve is provided inside the unit. Check that this air purgevalve is NOT tightened too much, so that automatic release of airfrom the water circuit is possible. Refer to field setting  [E‑04] in"6.2.9 Field settings on the remote controller" on page 15.

Inverter heat pump chilling unit with separate hydro module4P508019-1 – 2017.10

WARNING

▪ For correct operation of the system, a regulating valvemust be installed in the water system. The regulatingvalve is to be used to regulate the water flow in thesystem (field supply).

▪ Selecting a flow outside the curves can causemalfunction or damage to the unit. Also refer to theTechnical specifications.

▪ The maximum water piping temperature is 50°C according tosafety device setting.

▪ Always use materials which are compatible with the water used inthe system and with the materials used in the unit. (The unit pipingfittings are made of brass, the plate heat exchangers are made ofstainless steel 316 plates brazed together with copper and theoptional pump housing is made of cast iron.)

▪ Select the piping diameter in relation to the required water flowand available external static pressure (ESP) of the pump. See thefollowing table for the recommended water piping diameter.

Capacity class Water piping diameter20+32 1-1/4"40+64 2"

NOTICE

It is strongly recommended to install an additional filter onthe water circuit. Especially to remove metallic particlesfrom the field water piping, it is advised to use a magneticor cyclone filter which can remove small particles. Smallparticles can damage the unit and will not be removed bythe standard filter of the unit.

▪ Water pressure. Take care that the components installed in thefield piping can withstand the water pressure (maximum 3 bar +static pressure of the pump).

4.2.2 Formula to calculate the expansion vesselpre-pressure

The pre-pressure (Pg) of the vessel depends on the installationheight difference (H):

Pg=0.3+(H/10) (bar)

4.2.3 To check the water volume and expansionvessel pre-pressure

The unit has an expansion vessel of 12  litre with a default pre-pressure of 1 bar.

See the installer and user reference guide for more information.

To make sure that the unit operates properly:

▪ You must check the minimum and maximum water volume.

▪ You might need to adjust the pre-pressure of the expansionvessel.

Minimum water volume

Model Minimum total water volume (l)20 7632 11040 15264 220

INFORMATION

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

INFORMATION

The temperature step difference can be modified usingsettings [A‑02] and [F‑00]. This has an impact on theminimum water volume required when the unit operates incooling.

By default, the unit is set to have a water temperaturedifference of 3.5 K which allows it to operate with theminimum volume mentioned in the previous table.However, if a smaller temperature differential is set, as inthe case of process cooling applications wheretemperature fluctuations must be avoided, a largerminimum water volume will be required.

To ensure proper operation of the unit when changing thevalues of setting [F‑00] (for cooling mode), the minimumwater volume has to be corrected. If this volume exceedsthe range allowed in the unit, an additional expansionvessel or a buffer tank must be installed in the field piping.

Example:

To illustrate the impact on the system when modifying the setting[F‑00], we will consider a unit with a minimum allowable watervolume of 66  l. The unit is installed 5 m below the highest point inthe water circuit.

Assuming that the setting [F‑00] is changed from 5°C (default value)to 0°C. From the below table we see that 5°C corresponds to atemperature differential of 3.5 K and 0°C to 1 K, which is actually thelowest value we can set.

[F‑00] value (°C) Temperature differential (K)0 11 1.52 23 2.54 35 3.56 47 4.58 59 5.510 611 6.512 713 7.514 815 8.5

The water volume correction factor according to the curve shown inthe below graph is 3.5; this means that the minimum volume will be3.5 times larger.

When multiplying 64 l by the correction factor, we get 224  l, whichwill be the minimum water volume allowed in the installation if atemperature differential of 1 K is used.

Now it is very important to check that for the height difference of thesystem, the volume in the system is less than the maximum allowedvalue at that pre-pressure (Pg). If we take a look at the curve, for1 bar of pre-pressure, the maximum volume allowed is 350 l.

The total volume in the system will definitely be larger after addingthe internal volume of the unit. In this case, some pre-pressure canbe applied or an additional expansion vessel or buffer tank must beinstalled in the field piping.

The default value of pre-pressure (Pg) is for a height difference of7 m.

If the height difference of the system is lower than 7  m AND thevolume in the system is less than the maximum allowed value at thatpre-pressure (Pg) (see graph), then NO pre-pressure (Pg)adjustment is required.

Maximum water volumeUse the following graph to determine the maximum water volume forthe calculated pre-pressure.

If the total water volume in the entire circuit exceeds the maximumallowed water volume (see graph), an additional expansion vesselmust be installed in the field piping.

4.2.4 Changing the pre-pressure of theexpansion vessel

NOTICE

Only a licensed installer may adjust the pre-pressure of theexpansion vessel.

When changing the default pre-pressure of the expansion vessel(1 bar) is required, take following guidelines into account:

▪ Only use dry nitrogen to set the expansion vessel pre-pressure.

▪ Inappropriate setting of the expansion vessel pre-pressure willlead to malfunction of the system.

Changing the pre-pressure of the expansion vessel should be doneby releasing or increasing nitrogen pressure through the Schradervalve of the expansion vessel.

a Schrader valve

4.2.5 To check the water volume: ExamplesExample 1

The unit is installed 5 m below the highest point in the water circuit.The total water volume in the water circuit is 250 l.

No actions or adjustments are required.

Example 2

The unit is installed at the highest point in the water circuit. The totalwater volume in the water circuit is 420 l.

Actions:

▪ Because the total water volume (420  l) is more than the defaultwater volume (340 l), the pre-pressure must be decreased.

▪ The required pre-pressure is:Pg=(0.3+(H/10)) bar=(0.3+(0/10)) bar=0.3 bar

▪ The corresponding maximum water volume is approximately 490 l(see graph).

▪ Because 420  l is lower than 490  l, the expansion vessel isappropriate for the installation.

4.3 Preparing refrigerant piping

4.3.1 Refrigerant piping requirements

NOTICE

Refrigerant R410A requires strict cautions for keeping thesystem clean and dry. Foreign materials (including mineraloils or moisture) should be prevented from getting mixedinto the system.

NOTICE

The piping and other pressure-containing parts shall besuitable for refrigerant. Use phosphoric acid deoxidisedseamless copper for refrigerant.

▪ Air in the water circuit can cause malfunctioning. Duringfilling, it may not be possible to remove all the air fromthe circuit. Remaining air will be removed through theautomatic air purge valves during the initial operatinghours of the system. Additional filling with waterafterwards may be required.

▪ To purge the system, use the special function asdescribed in "7 Commissioning" on page 20.

NOTICE

The water pressure indicated on the manometer will varydepending on the water temperature (higher pressure athigher water temperature).

However, at all times water pressure shall remain above1 bar to avoid air entering the circuit.

NOTICE

Make sure water quality complies with EU directive98/83 EC.

INFORMATION

The unit may dispose of some excessive water through thepressure relief valve.

5.3.3 To insulate the water pipingThe complete water circuit, inclusive all piping, must be insulated toprevent condensation during cooling operation and reduction of theheating and cooling capacity as well as prevention of freezing of theoutside water piping during winter time. The thickness of theinsulation materials must be at least 13 mm with λ=0.039 W/mK inorder to prevent freezing of the outside water piping at ambienttemperature of –15°C.

If the temperature is higher than 30°C and the humidity is higherthan RH 80%, the thickness of the insulation materials should be atleast 20  mm to prevent condensation on the surface of theinsulation.

5.4 Connecting the refrigerant piping▪ For the SEHVX20+32BAW, remove the top knockout hole in the

side service plate and add the grommet (accessory) to cover anyburrs. For the SEHVX40+64BAW, remove both top and bottomknockout holes in the side service plate and add the grommets(accessory) to cover any burrs.

Space heating based on ON/OFF instructionPress The schedule timer for space heating will stop

(when active at that moment) and will startagain at the next scheduled ON function.

The "last" programmed command overrules the"preceding" programmed command and willremain active until the "next" programmedcommand occurs.

Example: imagine the actual time is 17:30 andactions are programmed at 13:00, 16:00 and19:00. The "last" programmed command(16:00) overruled the "previous" programmedcommand (13:00) and will remain active untilthe "next" programmed command (19:00)occurs.

So in order to know the actual setting, youshould consult the last programmed command(this may date from the day before).

The controller is switched off (operation LEDoff), but the schedule timer icon remains on.

Press The schedule timer for space heating and thequiet mode stops and will not start again.

The schedule timer icon is not displayed anymore.

▪ Operation example: Schedule timer based on ON/OFF instruction.When the setback function (see field setting  [2]) is enabled, thesetback operation will have priority over the scheduled action inthe schedule timer if ON instruction is active. If OFF instruction isactive this will have priority over the setback function. At any timethe OFF instruction will have the highest priority.

[3] Weather dependent setpoint

INFORMATION

This function is available for heat pump units operating inheating mode ONLY. It does NOT exist for cooling.

When weather dependent operation is active, the leaving watertemperature is determined automatically depending on the outdoortemperature: colder outdoor temperatures will result in warmer waterand vice versa. The unit has a floating setpoint. Activating thisoperation will result in a lower power consumption than use with amanually fixed leaving water setpoint.

During weather dependent operation, the user has the possibility toshift up or down the target water temperature by a maximum of 5°C.This "Shift  value" is the temperature difference between thetemperature setpoint calculated by the controller and the realsetpoint. E.g. a positive shift value means that the real temperaturesetpoint will be higher than the calculated setpoint.

It is advised to use the weather dependent setpoint because itadjusts the water temperature to the actual needs for space heating.It will prevent the unit from switching too much between thermo ONoperation and thermo OFF operation when using the remotecontroller room thermostat or external room thermostat.

The external room thermostat only gives an ON/OFF signal to theheat pump based on the room temperature. Because it does not givecontinuous feedback information to the heat pump, it issupplementary to the remote controller room thermostat function. Tohave a good control of the system and avoid frequent ON/OFF it isadvised to use the automatic weather dependent setpoint operation.

[E‑04] Pump only operation (air purge function)When installing and commissioning the unit it is very important toremove all air from the water circuit.

This field setting operates the pump to improve air removal from theunit without actually operating the unit. The pump will run for10 minutes, stop 2 minutes, etc.

[E‑04] Description0 (default) Normal operation of the unit

1 Automatic air purge operation during108 minutes

2 Automatic air purge operation during48 minutes

[F] Option setup

[F‑00] Return water temperature overshoot valueThis setting makes it possible to set the allowable overshoot whenoperating the unit during cooling THERMO ON/OFF condition.

The unit will go in THERMO ON only if the return water temperature(RWT) goes above the setpoint plus the differential temperature:

Thermo ON: RWT<Setpoint+(([F‑00]/2)+1)

The setting [F‑00] has a variability range from 0 to 15 and the step is1  degree. The default value is 5, meaning that the differentialtemperature default value is 3.5.

6.3 Switching between cooling andheating

Switching the unit between cooling and heating can be done in 2different ways. This will depend on how the temperature iscontrolled, i.e. based on room temperature or based on leavingwater temperature.

If the unit control is based on room temperature (external roomthermostat or remote controller room thermostat), switching betweencooling and heating is done through the remote controller by pushingthe cooling/heating button.

If the unit control is based on leaving water temperature, we suggestusing the ABC terminals on the outdoor unit (heat pump units only).The location of the terminals is shown in the following figure.

7 CommissioningAfter installation and once the field settings are defined, the installeris obliged to verify correct operation. Therefore a test run MUST beperformed according to the procedures described below.

7.1 Precautions when commissioningCAUTION

Do NOT perform the test operation while working onthe indoor units.

When performing the test operation, NOT only the outdoorunit, but the connected indoor unit will operate as well.Working on an indoor unit while performing a test operationis dangerous.

NOTICE

Be sure to turn on the power 6 hours before operation inorder to have power running to the crankcase heater andto protect the compressor.

During test operation, the outdoor unit and the indoor units will startup. Make sure that the preparations of all indoor and outdoor unitsare finished (field piping, electrical wiring, air purge, ...). Also see theinstallation manual of the outdoor unit for details.

7.2 Checklist before commissioningAfter the installation of the unit, first check the following items. Onceall below checks are fulfilled, the unit MUST be closed, ONLY thencan the unit be powered up.

Visually check the electrical component box and theinside of the unit on loose connections or damagedelectrical components.Pump rotation direction

If the 3-phase power input to the hydro module is notcorrectly wired (X1M), the pump may rotate in the wrongdirection. When this happens, the pump may slowlyoverheat due to reduced air flow, fan ventilation may bereduced and the motor may consume more power. Theindicator on the pump motor fan cover indicates thedirection of rotation of the pump. Check operation of thisindicator before starting the unit for the first time or whenthe position of the indicator has changed. If the indicator isin the white/reflecting field, switch off the power supplyand switch any two of the incoming supply wires at X1M.The correct direction of rotation is also shown by arrowson the pump motor fan cover.

12.3.5 Other operation modesStart up operationDuring start up, on the display means that the heat pump isstill starting up.

Defrost operation ( )

INFORMATION

This function is available for heat pump units ONLY.

In space heating operation, freezing of the outdoor heat exchangermay occur due to low outdoor temperature. If this risk occurs, thesystem goes into defrost operation. It reverses the cycle and takesheat from the water system to prevent freezing of the outdoorsystem. After a maximum of 15 minutes of defrost operation, thesystem returns to space heating operation. Space heating operationis not possible during defrost operation.

Quiet mode operation ( )Quiet mode operation means that the unit works at reducedcompressor speed so that the noise produced by the unit drops. Thisimplies that it will take longer until the required temperature setpointis reached. Beware of this when a certain level of heating is requiredindoors.

There are 3 different levels of quiet mode operation. The desiredquiet mode is set through a field setting.

12.3.6 Schedule timerPress to enable or disable the schedule timer ( ).

Four actions per day can be programmed, making a total of 28actions per week.

The schedule timer can be programmed in 2 different ways:

▪ based on the temperature setpoint (leaving water temperature androom temperature)

▪ based on the ON/OFF instruction.

The programming method is set in the field settings. See"6.2 Making field settings" on page 12. Before programming, fill outthe form at the very end of this document. This form can help youdefine the required actions for each day.

INFORMATION

▪ When power is restored after a power failure, the autorestart function reapplies the remote controller settingsat the time of the power failure (if the power wasinterrupted for less than 2  hours). It is thereforerecommended to leave the auto restart functionenabled.

▪ As the programmed schedule is time driven, it isessential to set the clock and the day of the weekcorrectly. See "12.3.1 About the clock" on page 26.

▪ Schedule timer actions will only be executed when theschedule timer is enabled ( visible on the display)!

▪ The programmed actions are not stored according totheir time of execution, but according to the time ofprogramming, i.e. action number  1 is the action thatwas programmed first, even though it may be executedafter other programmed action numbers.

▪ If 2 or more actions are programmed for the same dayand at the same time, only the action with the lowestaction number will be executed.

CAUTION

For use of units in applications with schedule timer mode, itis advised to foresee a delay of 10 to 15 minutes forsignalling the alarm in case the schedule timer isexceeded. The unit may stop for several minutes duringnormal operation for "defrosting of the unit" or when in"thermostat-stop" operation.

Space heating

[0‑03] StatusDefines whether the ON/OFF instruction can be used in theschedule timer for space heating.

Space heating based on ON/OFF instructionDuring operation When the schedule timer switches space

heating OFF, the controller will be switched off(operation LED will stop working).

Space heating based on ON/OFF instructionPress The schedule timer for space heating will stop

(when active at that moment) and will startagain at the next scheduled ON function.

The "last" programmed command overrules the"preceding" programmed command and willremain active until the "next" programmedcommand occurs.

Example: imagine the actual time is 17:30 andactions are programmed at 13:00, 16:00 and19:00. The "last" programmed command(16:00) overruled the "previous" programmedcommand (13:00) and will remain active untilthe "next" programmed command (19:00)occurs.

So in order to know the actual setting, youshould consult the last programmed command(this may date from the day before).

The controller is switched off (operation LEDoff), but the schedule timer icon remains on.

Press The schedule timer for space heating and thequiet mode stops and will not start again.

The schedule timer icon is not displayed anymore.

▪ Operation example: Schedule timer based on ON/OFF instruction.When the setback function (see field setting  [2]) is enabled, thesetback operation will have priority over the scheduled action inthe schedule timer if ON instruction is active. If OFF instruction isactive this will have priority over the setback function. At any timethe OFF instruction will have the highest priority.
