Pulling out the cooling moduleTo simplify transport and service, the heat pump canbe separated by pulling the cooling module out fromthe cabinet.

See page 64 for instructions about the separation.

AssemblyPosition F1245PC on a firm base that can take theweight, preferably on a concrete floor or foundation.Use the product's adjustable feet to obtain a horizont-al and stable set-up.

30 - 50 mm

The area where F1245PC is located must be equippedwith floor drainage.Install with its back to an outside wall, ideally in aroom where noise does not matter, in order to elim-inate noise problems. If this is not possible, avoidplacing it against a wall behind a bedroom or otherroom where noise may be a problem.Wherever the unit is located, walls to sound sensitiverooms should be fitted with sound insulation.

Route pipes so they are not fixed to an internal wallthat backs on to a bedroom or living room.

Installation areaLeave a space of 800 mm in front of the product. Ap-prox 50 mm free space is required in order to open theside hatches. The hatches do not need to be openedduring service, all service on F1245PC can be carriedout from the front. Leave space between the heatpump and wall behind (and any routing of supplycables and pipes) to reduce the risk reproduction ofany vibration.

Heat exchanger

System diagramF1245PC consists of a heat pump, water heater, elec-trical module, circulation pumps and a control system.F1245PC is connected to the brine and heating mediumcircuits.

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.

The brine can also be circulated via a mixing valve to aheat exchanger. There the brine cools the heating sys-tem's water so that comfort cooling can be maintainedduring the hotter periods of the year.

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 sideInsulate all indoor brine pipes against condensation.The level vessel must be installed as the highest pointin the brine system on the incoming pipe before thebrine pump (Alt. 1).

* Can be angled for side connection.

NIBE™ F1245PCChapter 4 | Pipe connections14

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.

P

Connecting external brine pump (10 kWonly)Install the brine pump at the connection for incomingbrine (XL6) between F1245PC and the shutoff valve(see illustration).

NOTE

Insulate the brine pump against condensation.

Heating medium sideConnecting the climate systemA climate system is a system that regulates indoorcomfort with the help of the control system in F1245PCand for example radiators, underfloor heating/cooling,fan convectors etc.

Install all required safety devices, shut-off valves (asclose 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 must

be 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.

P

Hot water heaterConnecting the hot water heater

The hot water heater in the heat pump must besupplied with necessary set of valves.The mixing valve must be installed if the setting ischanged 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 (10.0bar) 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 alternativesF1245PC can be connected in several different ways,some of 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 70 for a list of the accessoriesthat can be used with F1245PC.


Extra electric hot water heaterThe heat pump should be supplemented with an elec-tric water heater, for example NIBE COMPACT, if awhirlpool or other significant consumer of hot wateris installed.

The valve connection on COMPACT can be separated.The mixing valve remains on COMPACT and the re-maining valve connector can be used for incomingcold water in F1245PC.

Two or more climate systemsWhen more than one climate system, with a lowertemperature, is to be heated up, the following connec-tion can be used. The shunt valve lowers the temperat-ure to, for example, the under floor heating system.

The ECS 40/ECS 41 accessory is required for this con-nection.

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 page26 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.

PoolCharging of the pool is controlled by the pool sensor.In the case of low pool temperatures, the shuttle valvereverses direction and opens towards the pool ex-changer. The POOL 40 accessory is required for thisconnection.

Room sensorF1245PC is delivered with a room sensor supplied(BT50). The room temperature sensor has up to threefunctions:1. Show current room temperature in F1245PC's dis-

play.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 F1245PC's display the sensor must be in-stalled. Connect the room sensor to X6:3 and X6:4 onthe input circuit 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.

Optional connectionsLoad monitor

NOTE

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

When many power consumers are connected in theproperty at the same time as the electric addition isoperating, there is a risk of the property's main fusetripping. The heat pump has integrated load monitorsthat control the electrical steps for the electrical addi-tion by redistributing the power between the differentphases or disengaging in event of overload in a phase.Reconnection occurs when other current consumptionis 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 distribution box. Use a multi-corecable of at least 0.5 mm2 from the enclosure to theheat pump.

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

Filling and ventingCaution

Insufficient venting can damage internalcomponents in F1245PC.

Filling and venting the climate system

Filling1. Open the filling valve (external, not included with

the product). Fill the coil in the hot water heaterand the rest of the climate system with water.

2. Open the venting valve (QM22).3. When the water that exits the venting valve

(QM22) is not mixed with air, close the valve. Aftera while the pressure starts to rise.

4. Close the filling valve when the correct pressure isobtained.

Venting

NOTE

Insufficient venting can cause damage to in-ternal components.

1. Bleed the heat pump via the bleed valve (QM22)and the rest of the climate system via the relevantbleed valves.

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

TIP

If the heating medium pump (GP1) must berun during venting, it can be started via thestart guide.

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 necessarilyvented despite the flow of water when theventing valve (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 water

connection (XL3).3. When the water that comes out of the hot water

tap 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. Vent the brine system with venting valve on

F1245PC.9. Close the valves on the filler connector.10. Open the three way valve in the filler connector.11. If alternative 1 (level vessel) is used, open the valve

Menu 1.9.1 - heating curve

heating curve

Setting range: 0 - 15

Default value: 9

In the menu heating curve the so-called heating curvefor your house can be viewed. The task of the heatingcurve is to give an even indoor temperature, regardlessof the outdoor temperature, and thereby energy effi-cient operation. It is from this heating curve that theheat pump’s control computer determines the temper-ature of the water to the heating system, flow linetemperature, and therefore the indoor temperature.You can select heating curve and read off how the flowline temperature changes at different outdoor temper-atures here.

Brantare kurvlutning

The slope of the heating curve indicates how manydegrees the supply temperature is to be increased/re-duced when the outdoor temperature drops/increases.A steeper slope means a higher supply temperature ata certain outdoor temperature.

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 heating curve is set when the heating installationis installed, but may need adjusting later. Thereafterthe heating curve should not need further adjustment.

Caution

In the event of making fine adjustments forthe indoor temperature, the heat curve mustbe offset up or down instead, this is done inmenu 1.1 temperature .

Draining the water heaterThe siphon principle is used to empty the hot waterheater. This can be done either via the drain valve onthe incoming cold water pipe or by inserting a hoseinto the cold water connection.

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:

NIBE™ F1245PCChapter 9 | Service62

9 Service

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. Do this by slightly slackening offthe connection at the shut-off valve (QM32) thatjoins the heat pump to 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. Do this by slightly slackening offthe connection at the shut-off valve that joins theclimate system and the heat pump at the connec-tion (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. This is done by unscrewing thebleed screw 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 theother 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. Do this by slightly slackening offthe connection 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. Do this by slightly slackening offthe connection at the shut-off valve that joins thebrine side and the heat pump at the connection(XL7).

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

Helping the circulation pump to start (GP1)

1. Shut off F1245PC by setting the switch (SF1) to" ".

2. Open the service cover.3. 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 F1245PC by setting the switch (SF1) to "" and

check whether the circulation pump works.

It is usually easier to start the circulation pump withF1245PC running, switch (SF1) set to " ". Helping thecirculation pump to start is performed with F1245PCrunning, be prepared for the screwdriver to jerk whenthe pump starts.

USB service outlet

LEK

F1245PC is equipped with a USB socket in the displayunit. This USB socket can be used to connect a USBmemory to update the software, save logged informa-tion and handle the settings in F1245PC.

When a USB memory is connected a new menu (menu7) appears in the display.

Menu 7.1 - update firmware

This allows you to update the software in F1245PC.

NOTE

For the following functions to work the USBmemory must contain files with software forF1245PC from NIBE.

The fact box at the top of the display shows information(always in English) of the most probable update thatthe update software has selected form the USBmemory.

This information states which product the software isintended for, the software version and general inform-ation about them. If you wish to select another file thanthe one selected, the correct file can be selected by"choose another file".

start updating

Select “start updating" if you want to start the update.You are asked whether you really want to update thesoftware. Respond "yes" to continue or "no" to undo.

If you responded"yes" to the previous question theupdate starts and you can now follow the progress ofthe update on the display. When the update is com-plete F1245PC restarts.

NOTE

A software update does not reset the menusettings in F1245PC.

NOTE

If the update is interrupted before it is com-plete (for example power cut etc.) the softwarecan be reset to the previous version if the OKbutton is held in during start up until the greenlamp starts to illuminate (takes about 10seconds).


choose another file

Select “choose another file" if you do not want to usethe suggested software. When you scroll through thefiles, information about the marked software is shownin a fact box just as before. When you have selected afile with the OK button you will return to the previouspage (menu 7.1) where you can choose to start theupdate.

Menu 7.2 - logging

Setting range: 1 s – 60 min

Default setting range: 5 s

Set whether the present measurement values fromF1245PC are to be saved in a log on the USB memory.

Log for longer periods1. Set the desired interval between loggings.2. Tick “activated".3. The present values from F1245PC are saved in a

file in the USB memory at the set interval until“activated" is unticked.

Caution

Untick "activated" before removing the USBmemory.

Menu 7.3 - manage settings

Here you can manage (save as or retrieve from) all themenu settings (user and service menus) in F1245PCwith a USB memory.

Via "save settings" you save the menu settings to theUSB memory in order to restore them later or to copythe settings to another F1245PC.

NOTE

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 fault source. See page 48 for moreinformation about menu 3.1.

Manage 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 / action Here 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 68).

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.

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).
