GeneralPipe installation must be carried out in accordance withcurrent norms and directives. F1145 can operate witha return temperature of up to 58 °C and an outgoingtemperature from the heat pump of 70(65 °C with onlythe compressor).

F1145 is not equipped with external shut off valves;these must be installed to facilitate any future servicing.

Caution

Any high points in the climate system, mustbe equipped with air vents.

NOTE

The pipe system needs to be flushed out be-fore the heat pump is connected so that debriscannot damage component parts.

System diagramF1145 consists of heat pump, immersion heater, circu-lation pumps and control system. F1145 is connectedto 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 any dockedwater heater. If there is a greater need for heating/hotwater than the compressor can provide there is an in-tegrated immersion 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.

* Can be angled for side connection.

15Chapter 4 | Pipe connectionsNIBE™ F1145

■ The level vessel must be installed as the highest pointin the brine system on the incoming pipe before thebrine pump (Alt. 1).

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 hot water heater

NOTE

If F1145 is not docked to a water heater or ifit is to work with fixed condensing, the connec-tion for the water heater (XL9) must beplugged.

■ Any docked hot water heater must be fitted withnecessary 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 (10.0

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.

Room sensorF1145 is supplied with a room sensor enclosed (BT50).The room sensor has up to three functions:1. Show current room temperature in F1145'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 F1145'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.

transport.2. Check that the switch (SF1) is in position " ".3. Check for water in any hot water heater and cli-

mate system.

Caution

Check the miniature circuit-breaker and themotor protection breakers. They may havetripped during transportation.

NOTE

Do not start the heat pump, if there is a riskthat the water in the system has frozen.

Filling and ventingCaution

Insufficient venting can damage internalcomponents in F1145.

Filling and venting the climate system

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

the product). Fill the climate system with water.2. Open the venting valve .3. When the water that exits the venting valve is not

mixed with air, close the valve. After a while thepressure 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 a vent valve and the restof the climate system via their relevant vent valves.

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

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 thebrine system's filler connector as illustrated.

3. If alternative 1 (level vessel) is used, close the valveunder 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 38 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. F1145 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 F1145 installeras i en master/slav konfigura-tion, måste samtliga F1145 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 33.

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. F1145 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. F1145 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 47.

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. F1145 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 48.

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.

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.

Draining the water heater (if docked)The 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:

55Chapter 9 | ServiceNIBE™ F1145

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. 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 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. 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 F1145 -5 for -12 kW.

Other circulation pumps are used in othersizes.

1. Shut off, F1145 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 F1145 by setting the switch (SF1) to "" and

check whether the circulation pump works.

It is usually easier to start the circulation pump withF1145 running, switch (SF1) set to " ". If the circulationpump is helped to start while F1145 is running, beprepared for the screwdriver to jerk when the pumpstarts.

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 61).

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 hotwaterThis part of the fault-tracing chapter only applies if theheat pump is docked to the hot water heater.■ Closed or choked filling valve for the hot water

heater.■ Open the valve.

■ Mixing valve (if there is one installed) set too low.■ Adjust the mixer 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.
