System diagramF1245 consists of a heat pump, water heater, electricalmodule, circulation pumps and a control system. F1245is connected to the brine and heating medium circuits.

In the heat pump evaporator, the brine (water mixedwith anti-freeze, glycol or ethanol) releases its energyto the refrigerant, which is vaporised in order to becompressed in the compressor. The refrigerant, ofwhich the temperature has now been raised, is passedto the condenser where it gives off its energy to theheating medium circuit and, if necessary, to the waterheater. If there is a greater need for heating/hot waterthan the compressor can provide there is an integratedimmersion heater.

Applies to PEM hose 40x2.4 PN 6.3.

These are rough example values. At installation thecorrect calculations must be made according to localconditions.

Caution

The length of the collector hose varies depend-ing on the rock/soil conditions, climate zoneand on the climate system (radiators or under-floor heating).

Max length per coil for the collector should not exceed400 m.

In those cases where it is necessary to have severalcollectors, these should be connected in parallel withthe possibility for adjusting the flow of the relevantcoil.

For surface soil heat, the hose should be buried at adepth determined by local conditions and the distancebetween the hoses should be at least 1 metre.

For several bore holes, the distance between the holesmust be determined according to local conditions.

Ensure the collector hose rises constantly towards theheat pump to avoid air pockets. If this is not possible,airvents should be used.

As the temperature of brine system can fall below 0 °Cit must be protected against freezing down to -15 °C.1 litre of ready mixed brine per meter of collector hose(applies when using PEM-hose 40x 2.4 PN 6.3) is usedas a guide value when making the volume calculation.

Side connectionIt is possible to angle the brine connections, for connec-tion to the side instead of top connection.

To angle out a connection:1. Disconnect the pipe at the top connection.2. Angle the pipe in the desired direction.3. If necessary, cut the pipe to the desired length.

Connecting the brine side■ Insulate all indoor brine pipes against condensation.■ The level vessel must be installed as the highest point

in the brine system on the incoming pipe before thebrine pump (Alt. 1).

* Can be angled for side connection.

17Chapter 4 | Pipe connectionsNIBE™ F1245

If the level vessel cannot be placed at the highestpoint an expansion vessel must be used (Alt. 2).

NOTE

Note that condensation may drip from thelevel vessel. Position the vessel so that this doesnot harm other equipment.

■ Details of the antifreeze used must be shown on thelevel vessel.

■ Install the supplied safety valve under the level vesselas illustrated. The entire length of the overflow waterpipe from the safety valves must be inclined to pre-vent water pockets and must also be frost proof.

■ Install shut off valves as close to the heat pump aspossible.

■ Fit the supplied particle filter on the incoming pipe.

In the case of connection to an open groundwatersystem, an intermediate frost-protected circuit mustbe provided, because of the risk of dirt and freezing inthe evaporator. This requires an extra heat exchanger.

Connecting the climate systemA climate system is a system that regulates indoorcomfort with the help of the control system in F1245and for example radiators, underfloor heating/cooling,fan convectors etc.■ Install all required safety devices, shut-off valves (as

close to the heat pump as possible), and suppliedparticle filter.

■ The safety valve must have a maximum 0.25 MPa (2.5bar) opening pressure and be installed on the heatingmedium return as illustrated. The entire length ofthe overflow water pipe from the safety valves mustbe inclined to prevent water pockets and must alsobe frost proof.

■ When connecting to a system with thermostats onall radiators, a relief valve must be fitted, or some ofthe thermostats must be removed to ensure sufficientflow.

Connecting the hot water heater■ The hot water heater in the heat pump must be

supplied with necessary set of valves.■ The mixing valve must be installed if the setting is

changed so that the temperature can exceed 60 °C.■ The setting for hot water is made in menu 5.1.1.■ The safety valve must have a maximum 1.0 MPa (10.0

bar) opening pressure and be installed on the incom-ing domestic water line as illustrated. The entirelength of the overflow water pipe from the safetyvalves must be inclined to prevent water pockets andmust also be frost proof.

Docking alternativesF1245 can be connected in several different ways, someof which are shown below.

Further option information is available at www.nibe.euand in the respective assembly instructions for the ac-cessories used. See page 65 for a list of the accessoriesthat can be used with F1245.

Buffer vesselIf the climate system volume is too small for the heatpump output, the radiator system can be supplementedwith a buffer vessel, for example NIBE UKV.

Ground water systemAn intermediate heat exchanger is used to protect theheat pump's exchanger from dirt. The water is releasedinto a buried filtration unit or a drilled well. See page30 for more information about connecting a groundwater pump.

If this docking alternative is used, "min. brine out" inmenu 5.1.7 "br pmp al set." must be changed to asuitable value to prevent freezing in the heat ex-changer.

Ventilation recoveryThe installation can be supplemented with the exhaustair module FLM to provide ventilation recovery.■ Pipes and other cold surfaces must be insulated with

diffusion-proof material to prevent condensation.■ The brine system must be supplied with a pressure

expansion vessel (CM3). If there is a level vessel (CM2)this should be replaced.

GeneralAll electrical equipment, except the outdoor sensors,room sensors and the current sensors are ready connec-ted at the factory.■ Disconnect the heat pump before insulation testing

the house wiring.■ F1245 is not reconnectable between 1-phase and 3-

phase, neither is it reconnectable between 3x230Vand 3x400V.

■ If the building is equipped with an earth-faultbreaker, F1245 should be equipped with a separateone.

■ If a miniature circuit breaker is used this should haveat least motor characteristic “C”. See page 68 for fusesize.

■ Electrical wiring diagrams for the heat pump, seeseparate installation handbook for electrical wiringdiagrams.

■ Communication and sensor cables to external con-nections must not be laid close to high current cables.

■ The minimum area of communication and sensorcables to external connections must be 0.5 mm² upto 50 m, for example EKKX or LiYY or equivalent.

Room sensorF1245 is supplied with a room sensor enclosed (BT50).The room sensor has up to three functions:1. Show current room temperature in F1245's display.2. Option of changing the room temperature in °C.3. Makes it possible to change/stabilise the room

temperature.

Install the sensor in a neutral position where the settemperature is required. A suitable location is on a freeinner wall in a hall approx. 1.5 m above the floor. It isimportant that the sensor is not obstructed frommeasuring the correct room temperature by beinglocated, for example, in a recess, between shelves, be-hind a curtain, above or close to a heat source, in adraft from an external door or in direct sunlight. Closedradiator thermostats can also cause problems.

The heat pump operates without the sensor, but if onewishes to read off the accommodation's indoor tem-perature in F1245's display, the sensor must be in-stalled. Connect the room sensor to X6:3 and X6:4 onthe input board (AA3).

If the sensor is to be used to change the room temper-ature in °C and/or to change/stabilise the room tem-perature, the sensor must be activated in menu 1.9.4.

If the room sensor is used in a room with under floorheating it should only have an indicatory function, notcontrol of the room temperature.

Load monitor

NOTE

The load monitor has no function in a 1-phaseinstallation.

When many electrical appliances are connected in theproperty at the same time as the electric additionalheat is operating, there is a risk of the property's mainfuse tripping. The heat pump has integrated loadmonitors that control the electrical steps for the elec-trical addition by redistributing the power betweenthe different phases or disengaging in event of over-load in a phase. Reconnection occurs when other cur-rent consumption is reduced.

Connecting current sensors

A current sensor should be installed on each incomingphase conductor in to the distribution box to measurethe current. The distribution box is an appropriate in-stallation point.

Connect the current sensors to a multi-core cable in anenclosure next to the electrical distribution unit. Themulti-core cable between the enclosure and the heatpump must have a cable area of at least 0.5 mm².

Connect the cable to the input board (AA3) on terminalX4:1-4 block - where X4:1 is the common terminal blockfor the three current sensors.

The size of the property's main fuse is set in menu5.1.12.

NOTE

Insufficient venting can cause damage to in-ternal components.

1. Bleed the heat pump via a vent valve (QM22) andthe rest of the climate system via their relevant ventvalves.

2. Keep topping up and venting until all air has beenremoved and the pressure is correct.

NOTE

The pipe from the coil in the container mustbe drained of water before air can be released.This means that the system is not necessarilybled despite the flow of water when the ventvalve (QM22) is opened.

Filling the hot water heater

1. Open a hot water tap in the house.

2. Fill the hot water heater through the cold waterconnection (XL3).

3. When the water that comes out of the hot watertap is no longer mixed with air, the water heateris full and the tap can be closed.

Filling and venting the brine system

NOTE

Insufficient venting can cause damage to thebrine pump.

When filling the brine system, mix the water with anti-freeze in an open container. The mixture should beprotected against freezing down to about -15 °C. Thebrine is filled by connecting a filling pump.1. Check the brine system for leakage.2. Connect the filling pump and return line on the

brine system's filler connector as illustrated.3. If alternative 1 (level vessel) is used, close the valve

under the level vessel (CM2).4. Close the three way valve in the filler connector

(accessory).5. Open the valves on the filler connector.6. Start the filling pump.7. Fill until liquid enters the return pipe.8. Close the valves on the filler connector.9. Open the three way valve in the filler connector.10. If alternative 1 (level vessel) is used, open the valve

under the level vessel (CM2).

Start guideNOTE

There must be water in the climate systembefore the switch is set to " ".

NOTE

With several heat pumps connected the startguide must first be run in the slave units.

If you set a heat pump to slave you can onlymake settings for the slave's circulation pumps.Other settings are made and controlled by themaster unit.

1. Set the heat pump's switch (SF1) to "".2. Follow the instructions in the start guide in the

heat pump display. If the start guide does not startwhen you start the heat pump, start it manually inmenu 5.7.

TIP

See page 40 for a more in-depth introductionto the heat pump’s control system (operation,menus etc.).

CommissioningThe first time the heat pump is started a start guide isstarted. The start guide instructions state what needsto carried out at the first start together with a runthrough of the heat pump’s basic settings.

The start guide ensures that start-up is carried outcorrectly and cannot be bypassed.The start guide canbe started later in menu 5.7.

Caution

As long as the start guide is active, no functionin the installation will start automatically.

The guide will appear at each installation re-start until it is deselected on the last page.

Post adjustment and venting

Pump adjustment, automatic operation

Brine side

To set the correct flow in the brine system, the brinepump must run at the correct speed. F1245 has a brinepump that can be automatically controlled in standardmode. Certain functions and accessories may requirethat they are run manually and the correct speed mustthen be set, see section Pump adjustment, manualoperation.

Om flera F1245 installeras i en master/slav konfigura-tion, måste samtliga F1245 vara av samma storlek (t.ex.10 kW) för att den automatiska regleringen skafungera. Skulle installationen innehålla t.ex. en 8 kWoch en 10 kW måste injustering enligt manuell driftgöras, se sida 36.

This automatic control occurs when the compressor isrunning and sets the speed of the brine pump to obtainthe optimal temperature difference between the supplyand return lines. For passive cooling operation, for ex-ample, the brine pump must run at a set speed, whichis set in menu 5.1.9

Heating medium side

To set the correct flow in the heating medium system,the heating medium pump must run at the correctspeed. F1245 has a heating medium pump that can beautomatically controlled in standard mode. Certainfunctions and accessories may require that they arerun manually and the correct speed must then be set,see section Pump adjustment, manual operation.

This automatic control occurs when the compressor isrunning and sets the speed of the heating mediumpump, for the present operating mode, to obtain theoptimal temperature difference between the supplyand return lines. During heating operation, the set DOT(dimensioned outdoor temperature) and temperaturedifferential in menu 5.1.14 are used instead. If neces-sary, the maximum speed of the circulation pump canbe limited in menu 5.1.11.


Pump adjustment, manual operation

Brine side

To set the correct flow in the brine system the correctspeed must be set for the brine pump. F1245 has abrine pump that can automatically controlled, but if amanual speed is desired it must be set according to thefollowing information and diagram. For manual oper-ation "auto" must be deactivated in menu 5.1.9.

The flow must have a temperature difference betweenbrine out (BT11) and brine in (BT10) of 2 - 5 °C whenthe system is balanced (suitably 5 minutes after com-pressor start). Check these temperatures in menu 3.1"service info" and adjust the brine pump (GP2) speeduntil the temperature difference is achieved. A highdifference indicates a low brine flow and a low differ-ence indicates a high brine flow.

Set the speed of the brine pump in menu 5.1.9, seepage 49.

Read off what speed the brine pump should haveduring manual operation from the diagram below.

Heating medium side

To set the correct flow in the climate system, the correctspeed must be set for the heating medium pump inthe different operating conditions. F1245 has a heatingmedium pump that can automatically be controlled,but if a manual speed is desired it must be set accordingto the following information and diagram. For manualoperation, "auto" must be deactivated in menu 5.1.11.

The flow must have a suitable temperature differencefor the operating case (heating operation: 5 - 10 °C,hot water generation: 5 - 10 °C, pool heating: approx.15 °C) between controlling supply temperature sensorand return line sensor. Check these temperatures inmenu 3.1"service info and adjust the heating mediumpump (GP1) speed until the temperature difference isachieved. A high difference indicates a low heatingmedium supply and a low difference indicates a highheating medium supply.

Set the speed of the heating medium pump in themenu 5.1.11, see page 49.

Read off what speed the heating medium pump shouldhave during manual operation from the diagrams be-low.

Check the fluid level in the level vessel(CM2). If the fluid level has dropped, topup the system.1. Close the valve under the vessel.2. Disconnect the connection on top of

the vessel.3. Fill with brine until approx 2/3 of the

vessel is full.4. Reconnect the connector at the top of

the vessel.5. Open the valve under the vessel.

If the pressure in the system needs to be raised, it israised by closing the valve on the incoming main linewhen the brine pump (GP2) is running and the levelvessel (CM2) is open, so that liquid is drawn down fromthe vessel.

LEK

If a pressure expansion vessel (CM3) is usedinstead of a level vessel, the pressure levelis checked. If the pressure drops, the sys-tem should be replenished.

Post adjusting the roomtemperatureIf the required room temperature is not obtained, re-adjustment may be necessary.

You can select heating or cooling in the curve menu.The next menu (heating curve/cooling curve) showsthe heating and cooling curves for your house. The taskof the curve is to give an even indoor temperature, re-gardless of the outdoor temperature, and thereby en-ergy efficient operation. It is from these heat curvesthat the heat pump’s control computer determines thetemperature of the water to the system, the supplytemperature, and therefore the indoor temperature.Select the curve and read off how the supply temper-ature changes at different outdoor temperatures here.The number to the far right of "system" displays whichsystem you have selected the heating curve/coolingcurve for.

Curve coefficientThe slopes of the heating /cooling curves indicate howmany degrees the supply temperature is to be in-creased/reduced when the outdoor temperaturedrops/increases. A steeper slope means a higher supplytemperature for heating or a lower supply temperaturefor cooling at a certain outdoor temperature.

Supply temperature

Outdoor temperature

Steeper curve slope

The optimum slope depends on the climate conditionsin your location, if the house has radiators or underfloor heating and how well insulated the house is.

The curve is set when the heating installation is in-stalled, but may need adjusting later. Normally, thecurve will not need further adjustment.

Caution

In the event of making fine adjustments of theindoor temperature, the curve must be offsetup or down instead, this is done in menu 1.1temperature .

Curve offsetAn offset of the curve means that the supply temperat-ure changes as much for all the outdoor temperatures,e.g. that a curve offset of +2 steps increases the supplytemperature by 5 C at all outdoor temperatures.

Flow line temperature– maximum andminimum valuesBecause the flow line temperature cannot be calculatedhigher than the set maximum value or lower than theset minimum value the heating curve flattens out atthese temperatures.

Caution

Underfloor heating systems are normally maxflow line temperature set between 35 and 45°C.

Must be restricted with underfloor coolingmin. flow line temp. to prevent condensation.

Check the max temperature for your floor withyour installer/floor supplier.

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

Curve 0 is an own curve created in menu 1.9.7.

To select another curve (slope):

NOTE

If you only have one climate system, the num-ber of the curve is already marked when themenu window opens.

1. Select the climate system (if more than one) forwhich the curve is to be changed.

2. When the climate system selection has been con-firmed, the curve number is marked.

3. Press the OK button to access the setting mode4. Select a new curve. The curves are numbered from

0 to 15, the greater the number, the steeper theslope and the greater the supply temperature.Curve 0 means that own curve (menu 1.9.7) isused.

5. Press the OK button to exit the setting.

To read off a curve:1. Turn the control knob so that the ring on the shaft

with the outdoor temperature is marked.2. Press the OK button.3. Follow the grey line up to the curve and out to the

left to read off the value for the supply temperatureat the selected outdoor temperature.

4. You can now select to take read outs for differentoutdoor temperatures by turning the control knobto the right or left and read off the correspondingflow temperature.

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

TIP

Wait 24 hours before making a new setting,so that the room temperature has time tostabilise.

If it is cold outdoors and the room temperatureis too low, increase the curve slope by one in-crement.

If it is cold outdoors and the room temperatureis too high, lower the curve slope by one incre-ment.

If it is warm outdoors and the room temperat-ure is too low, increase the curve offset by oneincrement.

If it is warm outdoors and the room temperat-ure is too high, lower the curve offset by oneincrement.

9 Service

Draining the climate systemIn order to carry out service on the climate system, itmay be easier to drain the system first. This can be donein different ways depending on what needs doing:

NOTE

There may be some hot water when drainingthe heating medium side/climate system.There is a risk of scalding.

Draining the heating medium side in the coolingmodule

If, for example, the heating medium pump requiresreplacing or the cooling module requires servicing,drain the heating medium side as follows:1. Close the shut-off valves to heating medium side

(QM31) and (QM32).2. Connect a hose to the bleed valve (QM1) and open

the valve. Some liquid will run out.3. Air must get into the system for the remaining li-

quid to run out. To let in air, slacken off the connec-tion slightly at the shut-off valve (QM32) that joinsthe heat pump with the cooling module.

When the heating medium side is drained, the requiredservice can be performed and/or replacement of anycomponents carried out.

Draining the heating medium system in the heatpump

If the heat pump requires servicing, drain the heatingmedium side as follows:1. Close the shut-off valves outside the heat pump

for the heating medium side (return and flow line).2. Connect a hose to the bleed valve (QM1) and open


quid to run out. To let in air, slacken off the connec-tion slightly at the shut-off valve that joins the heatpump with the cooling module (XL2).

When the heating medium side is empty the requisiteservice can be carried out.

Draining the entire climate system

If the entire climate system requires draining, do thisas follows:1. Connect a hose to the bleed valve (QM1) and open


quid to run out. To allow air in, unscrew the bleedscrew on the highest radiator in the house.

When the climate system is empty the requisite servicecan be carried out.

Emptying the brine systemIn order to service the brine system it may be easier todrain the system first. This can be done in differentways depending on what needs doing:

Draining the brine system in the cooling module

If, for example, the brine pump requires replacing orthe cooling module requires servicing, drain the brinesystem by:1. Close the shut-off valves to brine system (QM33)

and (QM34).2. Connect a hose to the drain valve (QM2), place the

other opening of the hose in a container and openthe valve. A small amount of brine will flow intothe container.

3. Air must get into the system for the remainingbrine to run out. To let in air, slacken off the con-nection slightly at the shut-off valve (QM33) thatjoins the heat pump with the cooling module.

When the brine side is empty the requisite service canbe carried out.

Draining the brine system in the heat pump

If the heat pump requires servicing, drain the brinesystem by:1. Close the shut-off valve outside the heat pump for

the brine system.2. Connect a hose to the drain valve (QM2), place the

other opening of the hose in a container and openthe valve. A small amount of brine will flow intothe container.

3. Air must get into the system for the remainingbrine to run out. To let in air, slacken off the con-nection slightly at the shut-off valve that joins thebrine side with the heat pump at connection (XL7).

When the brine side is empty the requisite service canbe carried out.

Helping the circulation pump to start (GP1)

NOTE

Help starting the heating medium pump (GP1)only applies to F1245 -5 for -12 kW.

1. Shut off, F1245 by setting the switch ((SF1)) to "".

2. Remove the front cover3. Remove the cover for the cooling module.4. Loosen the venting screw (QM5) with a screwdriver.

Hold a cloth around the screwdriver blade as asmall amount of water may run out.

5. Insert a screwdriver and turn the pump motoraround.

6. Screw in the venting screw (QM5).7. Start F1245 by setting the switch (SF1) to "" and

check whether the circulation pump works.

It is usually easier to start the circulation pump withF1245 running, switch (SF1) set to " ". If the circulationpump is helped to start while F1245 is running, beprepared for the screwdriver to jerk when the pumpstarts.

When you save the menu settings to the USBmemory you replace any previously saved set-tings on the USB memory.

Via "recover settings" you reset all menu settings fromthe USB memory.

NOTE

Reset of the menu settings from the USBmemory cannot be undone.


In most cases, the heat pump notes operational inter-ference (operational interference can lead to disturb-ance in comfort) and indicates this with alarms andshows action instructions in the display.

Info menuAll the heat pump measurement values are gatheredunder menu 3.1 in the heat pump menu system.Looking through the values in this menu can oftensimplify finding the source of the fault. See help menuor user manual for more information about menu 3.1.

alarm

In the event of an alarm, some kind of malfunction hasoccurred, which is indicated by the status lamp chan-ging from green continuously to red continuously. Inaddition, an alarm bell appears in the informationwindow.

AlarmIn the event of an alarm with a red status lamp a mal-function has occurred that the heat pump cannotremedy itself. In the display, by turning the control knoband pressing the OK button, you can see the type ofalarm it is and reset it. You can also choose to set theheat pump to aid mode.

info / actionHere you can read what the alarm meansand receive tips on what you can do to correct theproblem that caused the alarm.

reset alarm In most cases it is enough to select "resetalarm" to correct the problem that caused the alarm.If a green light illuminates after selecting "reset alarm"the alarm has been remedied. If a red light is still visibleand a menu called ”alarm” is visible in the display, theproblem that caused the alarm remains. If the alarmdisappears and then returns, see the troubleshootingsection (page 63).

aid mode ”aid mode” is a type of emergency mode.This means that the heat pump produces heat and/orhot water despite there being some kind of problem.This can mean that the heat pump's compressor is notrunning. In this case the immersion heater producesheat and/or hot water.

NOTE

To select aid mode an alarm action must beselected in the menu 5.1.4.

Caution

Selecting "aid mode” is not the same as correct-ing the problem that caused the alarm. Thestatus lamp will therefore continue to be red.

TroubleshootingIf the operational interference is not shown in the dis-play the following tips can be used:

Basic actionsStart by checking the following possible fault sources:■ The switch's (SF1) position.■ Group and main fuses of the accommodation.■ The property's earth circuit breaker.■ The heat pump's miniature circuit breaker (FA1).■ The heat pump's temperature limiter (FD1).■ 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.■ Open the valve.

■ Heat pump in incorrect operating mode.■ If mode "manual" is selected, select "addition".

■ Large hot water consumption.■ Wait until the hot water has heated up. Temporar-

ily increased hot water capacity (temporary lux)can be activated in menu 2.1.

■ Too low hot water setting.■ Enter menu 2.2 and select a higher comfort mode.

■ Too low or no operating prioritisation of hot water.■ Enter menu 4.9.1 and increase the time for when

hot water is to be prioritised.

Low room temperature■ Closed thermostats in several rooms.■ Set the thermostats to max, in as many rooms as

possible. Adjust the room temperature via menu1.1, instead of choking the thermostats.

■ Heat pump in incorrect operating mode.■ Enter menu 4.2. If mode "auto" is selected, select

a higher value on "stop heating" in menu 4.9.2.■ If mode "manual" is selected, select "heating". If

this is not enough, select "addition".■ Too low set value on the automatic heating control.■ Enter menu 1.1 "temperature" and adjust the offset

heating curve up. If the room temperature is onlylow in cold weather the curve slope in menu 1.9.1"heating curve" needs adjusting up.

■ Too low or no operating prioritisation of heat.■ Enter menu 4.9.1 and increase the time for when

heating is to be prioritised.■ "Holiday mode" activated in menu 4.7.■ Enter menu 4.7 and select "Off".
