F750 – An excellent choiceF750 is part of a new generation of heat pumps, which have been intro-duced to supply your homewith inexpensive and environmentally friendlyheating. Heat production is safe and economical with integrated hotwater heater, immersion heater, circulation pump and control system.

The heat pump can be connected to an optional low temperature heatdistribution system. e.g. radiators, convectors or under floor heating. Itis also prepared for connection to several different products and accessor-ies, e.g. extra water heater and climate systems with different temper-atures.

F750 is equipped with a control computer for good comfort, good eco-nomy and safe operation. Clear information about status, operation timeand all temperatures in the heat pump are shown on the large and easyto read display. This means, for example, that external unit thermometersare not necessary.

EXCELLENT PROPERTIES FOR F750:• Inverter controlled compressorThe heat pump has an inverter-controlled compressor that automaticallyadapts itself optimally and economically to your house and suppliesyour installation with heating and hot water.

• Buffer vesselThere is a buffer vessel integrated in the heat pump that equalises thetemperature of the water that is sent out in the climate system.

• Scheduling the indoor comfort and hot waterHeating and hot water as well as ventilation, can be scheduled for eachday of the week or for longer periods (vacation).

• Display with user instructionsThe heat pump has a large display with easy-to-understand menus thatfacilitate setting a comfortable climate.

• Simple troubleshootingIn the event of a fault, the heat pump display shows what happenedand the actions to be taken.

2 The heat pump – the heart ofthe house

Heat pump functionAn exhaust air heat pump makes use of the heat in the building's ventil-ation air to heat up the accommodation. The conversion of the ventilationair's energy to accommodation heating is done in three different circuits.From the outgoing ventilation air (1), free heating energy is retrievedfrom the accommodation and transported to the heat pump. The heatpump increases the retrieved heat's low temperature to a high temper-ature in the refrigerant circuit, (2). The heat is distributed around thebuilding in the heating medium circuit (3).

Ventilation airThe hot air is transferred from the rooms to the heat pump via the houseventilation system.

A

The fan then routes the air to the heat pump’s evaporator. Here, the air re-leases the heating energy and the air's temperature drops significantly. Thecold air is then blown out of the house.

B

Refrigerant circuitA liquid, a refrigerant, circulates in a closed system in the heat pump whichalso passes the evaporator. The refrigerant has a very low boiling point. Inthe evaporator the refrigerant receives the heat energy from the ventilationair and starts to boil.

C

The gas that is produced during boiling is routed into an electrically poweredcompressor. When the gas is compressed, the pressure increases and thegas’s temperature increases considerably, from approx. -5°C to approx.100°C.

D

From the compressor, the gas is forced into a heat exchanger, condenser,where it releases heat energy to the heat pump’s heating section, whereuponthe gas is cooled and condenses to liquid form again.

E

As the pressure is still high, the refrigerant can pass an expansion valve,where the pressure drops so that the refrigerant returns to its original tem-perature. The refrigerant has now completed a full cycle. It is routed to theevaporator again and the process is repeated.

F

Heat medium circuitThe heat energy that the refrigerant produces in the condenser is retrievedby the climate system's water, heating medium, which is heated to 55 °C(supply temperature).

G

The heating medium circulates in a closed system and transports the heatedwater's heat energy to the heat pump's integrated hot water heater and theradiators/heating coils of the house.

H

Buffer vessel

NIBE F750Chapter 2 | The heat pump – the heart of the house10

The heating medium passes the heat pump's integrated buffer vesselwhereupon the temperature is equalised. It is then transported to the heatingsystem of the house.

The temperatures are only examples and may vary between different installations andtime of year.

Maintenance of F750REGULAR CHECKSYour heat pump requires minimal maintenance after commissioning. Onthe other hand, it is recommended that you check your installation regu-larly.

If something unusual occurs, messages about the malfunction appearin the display in the form of different alarm texts. See alarmmanagementon page 72.

Service hatchThe vent valves etc. are behind the service hatch. Remove the hatch bypulling it towards you.

LEK

Cleaning the ventilation devicesThe building’s ventilation devices should becleaned regularly with, for example, a smallbrush to maintain the correct ventilation.

The device settings must not be changed.

NOTEIf you take down more than oneventilation device for cleaning, do notmix them up.


Cleaning the air filterClean the F750's air filter regularly, how often depends on the amountof dust in the ventilation air. Select what is most suitable for your install-ation.

You will receive a reminder about filter cleaning in the display. The defaultsetting for the reminder is every three months, however, if the powerto F750 is interrupted the countdown begins again.

1. Switch off the heat pump.

2. Remove the upper front cover by pulling straight out.

3. Pull out the filter cassette.

4. Carry out assembly in reverse order.

NOTEWater or other liquids must not be used for cleaning.

Check pressureF750 has a pressure gauge which shows the heating system pressure.The pressure should be between 0.5 and 1.5 bar, but varies duringtemperature changes. If the pressure drops to 0 or rises to 2.5 frequently,contact your installer for troubleshooting.

LEKLEK

Pressure gauge


Safety valvesF750 has two safety valves, one for the hot water heater and one forthe climate system.

The water heater’s safety valve sometimes releases a little water afterhot water usage. This is because the cold water, which enters the waterheater, expands when heated causing the pressure to rise and the safetyvalve to open. The climate system’s safety valve must be completelyclosed and must not normally release any water.

The function of the safety valves must be checked regularly. The valvesare accessed via the service hatch. Perform checks as follows:

1. Open the valve by turning the knob anti-clockwise carefully.

2. Check that water flows through the valve.

3. Close the valve by releasing it. If it does not close automatically whenreleased, turn it anti-clockwise slightly.

4. The climate systemmay need to be refilled after checking the safetyvalve, see the section “Filling the climate system”.

Filling the climate systemIf the pressure is too low, increase as follows:

1. For F750, stainless steel: Check if the flexi hose supplied is connectedbetween the two filler valves. Adjust the hose if this has not beendone.

2. For F750, stainless steel: Open the filling valves. The heating unitand the rest of the climate system fill with water.

For F750, copper: Open the filler valve . The heating section and therest of the climate system are filled with water.

3. After a while the pressure rises on the pressure gauge. When it isapprox. 1.0 bar close the filler valve.

Venting the climate systemIn event of repeated filling of the climate system or if bubbling soundsare heard from the heat pump the system may need venting. This iscarried out as follows:

1. Set the switch in mode and wait approx. 30 seconds.

2. Turn off the power supply to the heat pump.

3. Vent the heat pump via the vent valves and the rest of the climatesystem via its respective vent valves.

NOTEThe vent hoses from the container must be drained of waterbefore air can be released. This means that the system is notnecessarily vented despite the flow of water when the ventvalves are opened.

Therefore hold the vent valves open at least 5 seconds.


SAVING TIPSYour heat pump installation produces heat and hot water. This occursvia the control settings you made.

Factors that affect the energy consumption are, for example, indoortemperature, hot water consumption, the insulation level of the houseand whether the house has many large window surfaces. The positionof the house, e.g. wind exposure is also an affecting factor.

Also remember:

• During the adjustment period (winter time) all thermostat valves shouldbe fully open. The heat pump's heating settings are then adjusted sothat the correct indoor temperature is obtained, in most rooms, regard-less of the outdoor temperature. In rooms where a lower temperatureis required, the thermostat valves are lowered to the desired level.After a fewmonths, the remaining thermostats can be lowered slightlyto avoid an increase of the room temperature due to solar radiation,stove heat etc. Further reductions may be required later on.

• You can lower the temperature when away from the house byscheduling "holiday setting" in menu 4.7. See page 66 for instructions.

• You can reduce the ventilation speed when you are away by enteringa schedule in menu 1.3.3. See page 38 for instructions.

• If you activate "Hot water Economy", less energy is used.

Energy meter

Check the accommodation's energy meter regularly, preferably once amonth. This will indicate any changes in power consumption.

Newly built houses usually have twin energy meters, use the differenceto calculate your domestic electricity.

New builds

Newly built houses undergo a drying out process for a year. The housecan then consume significantly more energy than it would thereafter.After 1-2 years the heating curve should be adjusted again, as well asthe offset heating curve and the building's thermostat valves, becausethe heating system, as a rule, requires a lower temperature once thedrying process is complete.

Menu1.9.1

The prescribed heating curve for your house can be viewed in the menu heatingcurve . The task of the heating curve is to give an even indoor temperature, re-gardless of the outdoor temperature, and thereby energy efficient operation. Itis from this heating curve that the heat pump's control computer determinesthe temperature of the water to the heating system, supply temperature, andtherefore the indoor temperature. Select the heating curve and read off how thesupply temperature changes at different outdoor temperatures here.

Curve coefficientThe slope of the heating curve indic-ates how many degrees the supplytemperature is to be increased/re-ducedwhen the outdoor temperaturedrops/increases. A steeper slopemeans a higher supply temperatureat a certain outdoor temperature.

The optimum slope depends on the climate conditions in your location, if thehouse has radiators or under floor heating and how well insulated the house is.

The heating curve is set when the heating installation is installed, but may needadjusting later. Thereafter the heating curve should not need further adjustment.


CautionIn the event of making fine adjustments for the indoor temperature,the heat curve must be offset up or down instead, this is done in menu1.1 temperature .

Curve offsetAn offset of the heating curvemeansthat the supply temperature ischanged by the same amount for alloutdoor temperatures, e.g. a curveoffset of +2 steps increases thesupply temperature by 5 °C at alloutdoor temperatures.

The figure at the end of the curve indicates the curve slope. The figure besidethe thermometer gives the curve offset. Use the control knob to set a new value.Confirm the new setting by pressing the OK button.

Curve 0 is an own heating curve created in menu 1.9.7.


To select another heat curve (slope):

NOTEIf you only have one heating system, the number of the curve is alreadymarked when the menu window opens.

1. Select the system (if more than one) for which the heat curve is to bechanged.

2. When the system selection has been confirmed the heat curve number ismarked.

3. Press the OK button to access the setting mode

4. Select a new heating curve. The heating curves are numbered from 0 to 15,the greater the number, the steeper the slope and the greater the supplytemperature. Heating curve 0 means that own curve (menu 1.9.7) is used.

5. Press the OK button to exit the setting.

To read off a heating curve:1. Turn the control knob so that the ring on the shaft with the outdoor temper-

ature is marked.


3. Follow the grey line up to the heat curve and out to the left to read off thevalue for the supply temperature at the selected outdoor temperature.

4. You can now select to take read outs for different outdoor temperatures byturning the control knob to the right or left and read off the correspondingflow temperature.

5. Press the OK or Back button to exit read off mode.


TIPWait 24 hours before making a new setting, so that the room temper-ature has time to stabilise.

If it is cold outdoors and the room temperature is too low, increasethe curve slope by one increment.

If it is cold outdoors and the room temperature is too high, lower thecurve slope by one increment.

If it is warm outdoors and the room temperature is too low, increasethe curve offset by one increment.

If it is warm outdoors and the room temperature is too high, lower thecurve offset by one increment.

CautionA slow heating system such as underfloor heating may not be suitablefor control using the installation’s room sensors.

Here you can set a factor (a numerical value) that determines howmuch an overor sub normal temperature (the difference between the desired and actual roomtemperature) in the room is to affect the supply temperature to the climatesystem. A higher value gives a greater and faster change of the heating curve'sset offset.

In the event of an alarm, some kindof malfunction has occurred, which isindicated by the status lamp changingfrom green continuously to red con-tinuously. In addition, an alarm bellappears in the information window.

ALARMIn the event of an alarm with a redstatus lamp a malfunction has oc-curred that the heat pump cannot remedy itself. In the display, by turningthe control knob and pressing the OK button, you can see the type ofalarm it is and reset it. You can also choose to set the heat pump to aidmode.

info / action Here you can read what the alarm means and receive tipson what you can do to correct the problem that caused the alarm.

reset alarm In many cases, it is sufficient to select “reset alarm” in orderfor the product to revert to normal operation. If a green light comes onafter selecting “reset alarm”, the alarm has been remedied. If a red light

is still visible and a menu called “alarm” is visible in the display, theproblem causing the alarm still remains. If the alarm initially disappearsand then returns, you should contact your installer.

aid mode “aid mode” is a type of emergency mode. This means thatthe heat pump produces heat and/or hot water even though there issome kind of problem. This couldmean that the heat pump’s compressoris not running. In this case, the immersion heater produces heat and/orhot water.

CautionSelecting "aid mode” is not the same as correcting the problemthat caused the alarm. The status lamp will therefore continueto be red.

If the alarm does not reset, contact your installer for suitable remedialaction.

NOTEAlways state the product’s serial number (14 digits) when re-porting a fault.

TroubleshootingIf the operational interference is not shown in the display the followingtips can be used:

BASIC ACTIONSStart by checking the following possible fault sources:

• The switch's position.

• Group and main fuses of the accommodation.

• Earth-fault breaker.

• Correctly set load monitor (if installed).

LOW HOT WATER TEMPERATURE OR A LACK OF HOTWATER• Closed or choked filling valve for the hot water heater.

ADDITIONAL HEATThe additional heat is the heat produced in addition to the heat suppliedby the compressor in your heat pump. Additional heaters can be for ex-ample, immersion heater, electric heater, gas/oil/pellet/wood burner ordistrict heating.

BUFFER VESSELA buffer vessel increases the system volume and removes the unwantedtemperature variations that can otherwise be sent out on the climatesystem. This ensure the running of the heat pump and reduces the heatspikes that could otherwise be heard from the climate system.

CALCULATED FLOW LINE TEMPERATUREThe temperature that the heat pump calculates that the heating systemrequires for an optimum accommodation temperature. The colder theoutdoor temperature, the higher the calculated supply temperature.

CIRCULATION PUMPPump that circulates liquid in a pipe system.

CLIMATE SYSTEMClimate systems can also be called heating systems. The building isheated using radiators, under floor coils or convector fans.

COMPRESSORCompresses the gas state refrigerant. When the refrigerant is com-pressed, the pressure and the temperature increase.

CONDENSERHeat exchanger where the hot gas state refrigerant condenses (cooledand becomes a liquid) and releases heat energy to the house heatingand hot water systems.

DISTURBANCES IN COMFORTDisturbances in comfort are undesirable changes to the hot water/indoorcomfort, for example when the temperature of the hot water is too lowor if the indoor temperature is not at the desired level.

A malfunction in the heat pump can sometimes be noticed in the formof a disturbance in comfort.

Inmost cases, the heat pump notes operational interference and indicatesthis with alarms and shows instructions in the display.

DOMESTIC HOT WATERThe water one showers in for example.

ELECTRICAL ADDITIONThis is the electricity that, for example, an immersion heater produceswhen the compressor's output is not sufficient to fulfil the property'sheating demand.

EMERGENCY MODEA mode that can be selected using the switch in the event of a fault,which means that the compressor stops. When the heat pump is inemergencymode, the building is heated using an immersion heater. Hotwater is not produced.

EVAPORATORHeat exchanger where the refrigerant evaporates by retrieving heat en-ergy from the air which then cools.

EXHAUST AIRThe air that comes from the exhaust air device in the various rooms ofthe accommodation, to F750.

EXHAUST AIR DEVICESVents, usually in the ceiling, in the kitchen/bathroom/clothes closet wherethe air is drawn in to be forwarded to F750.

79Chapter 6 | GlossaryNIBE F750

EXPANSION VALVEValve that reduces the pressure of the refrigerant, whereupon the tem-perature of the refrigerant drops.

EXPANSION VESSELVessel with heatingmedium fluid with the task of equalising the pressurein the heating medium system.

EXTRACT AIRThe air that the heat pump has retrieved heat from and which hastherefore been cooled. This air is blown out of the building.

FILTERING TIMEIndicates the time the average outdoor temperature is calculated on.

FLOW PIPEThe line in which the heated water is transported from the heat pumpout to the house heating system (radiators/heating coils).

HEAT EXCHANGERDevice that transfers heat energy from one medium to another withoutmixing mediums. Examples of different heat exchangers include evapor-ators and condensers.

HEAT FACTORMeasurement of how much heat energy the heat pump gives off in re-lation to the electric energy it needs to operate. Another term for this isCOP.

HEATING CURVEThe heating curve determines which heat the heat pump is to producedepending on the temperature outdoors. If a high value is selected, thistells the heat pump that it must produce a lot of heat when it is coldoutdoors in order to achieve a warm indoor temperature.

HEATING MEDIUMHot liquid, usually normal water, which is sent from the heat pump tothe house climate system and makes the accommodation warm. Theheating medium also heats the hot water.


HEATING MEDIUM SIDEPipes to the house’s climate system make up the heating medium side.

MIXING VALVEA valve that mixes the cold water with the hot water leaving the heater.

OUTSIDE SENSORA sensor that is located outdoors. This sensor tells the heat pump howhot it is outdoors.

PRESSOSTATPressure switch that triggers an alarm and/or stops the compressor ifnon-permitted pressures occur in the system. A high pressure pressostattrips if the condensing pressure is too great. A low pressure pressostattrips if the evaporation pressure is too low.

RADIATORAnother word for heating element. Theymust be filled with water in orderto be used with F750.

REFRIGERANTSubstance that circulates around a closed circuit in the heat pump andthat, through pressure changes, evaporates and condenses. Duringevaporation, the refrigerant absorbs heating energy andwhen condensinggives off heating energy.

RETURN PIPEThe line in which the water is transported back to the heat pump fromthe house heating system (radiators/heating coils).

RETURN TEMPThe temperature of the water that returns to the heat pump after releas-ing the heat energy to the radiators/heating coils.

ROOM SENSORA sensor that is located indoors. This sensor tells the heat pump howhot it is indoors.

81Chapter 6 | GlossaryNIBE F750

SAFETY VALVEA valve that opens and releases a small amount of liquid if the pressureis too high.

SHUNTA valve that mixes the hot water with a small amount of slightly coolerwater.

SHUTTLE VALVEA valve that can send liquid in two directions. A shuttle valve that enablesliquid to be sent to the climate system, when the heat pump producesheating for the house, and to the hot water heater, when the heat pumpproduces hot water.

SUPPLY TEMPERATUREThe temperature of the heated water that the heat pump sends out tothe heating system. The colder the outdoor temperature, the higher thesupply line temperature becomes.

WATER HEATERContainer where domestic water is heated. Is located inside the heatpump, but an extra hot water heater can be installed in the event of largehot water requirements.
