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

See page 61 for instructions about the separation.

AssemblyPosition F1155 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 F1155 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 F1155 can be carried outfrom the front. Leave space between the heat pumpand wall behind (and any routing of supply cables andpipes) to reduce the risk reproduction of any vibration.

(50) (50)

* A normal installation needs 300 - 400 mm (any side) for connec-tion equipment, i.e. level vessel, valves and electrical equipment.

GeneralPipe installation must be carried out in accordance withcurrent norms and directives. F1155 can operate witha return temperature of up to 58 °C and an outgoingtemperature from the heat pump of 70 (65 °C withonly the compressor).

F1155 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 diagramF1155 consists of heat pump, immersion heater, circu-lation pumps and control system. F1155 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.

Brine sideCollector

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) and the heating requirement ofthe building Each installation must be sizedindividually.

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).

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.

* Can be angled for side connection.

NIBE™ F1155Chapter 4 | Pipe connections12

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

Heating medium sideConnecting the climate systemA climate system is a system that regulates indoorcomfort with the help of the control system in F1155and 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 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.

T

Hot water heaterConnecting the hot water heater

NOTE

If F1155 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 (10.0bar) 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.

Room sensorF1155 is delivered with a room sensor supplied (BT50).The room temperature sensor has up to three functions:1. Show current room temperature in F1155'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 F1155's display the sensor must be installed.Connect the room sensor to X6:3 and X6:4 on the inputcircuit 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.

LEK

Optional connectionsLoad monitorWhen 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 the electrical addi-tion in event of overload in a phase. If the overload re-mains despite the electrical addition being disengaged,the compressor winds down. Reconnection occurswhen other current 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 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.

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

You can select heating or cooling in the curve menu.The next menu (heating curve/cooling curve) shows

the 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 coefficient

The 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.

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 offset

An 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 and minimumvalues

Because 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

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


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.

Menu 1.9.2 - external adjustment

Setting range: -10 to +10 or desired room temperat-ure if the room sensor is installed.

Default value: 0

Connecting an external contact, for example, a roomthermostat or a timer allows you to temporarily orperiodically raise or lower the room temperature whileheating. When the contact is on, the heat curve offsetis changed by the number of steps selected in themenu. If a room sensor is installed and activated thedesired room temperature (°C) is set.

If there is more than one climate system the settingcan be made separately for each system.

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:

59Chapter 9 | ServiceNIBE™ F1155

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

1. Shut off F1155 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 F1155 by setting the switch (SF1) to "" and

check whether the circulation pump works.

It is usually easier to start the circulation pump withF1155 running, switch (SF1) set to " ". Helping the cir-culation pump to start is performed with F1155 run-ning, be prepared for the screwdriver to jerk when thepump starts.

USB service outlet

LEK

F1155 is equipped with a USB socket in the display unit.This USB socket can be used to connect a USB memoryto update the software, save logged information andhandle the settings in F1155.

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 F1155.

NOTE

For the following functions to work the USBmemory must contain files with software forF1155 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 F1155 restarts.

NOTE

A software update does not reset the menusettings in F1155.

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 fromF1155 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 F1155 are saved in a file

in the USB memory at the set interval until “activ-ated" 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 F1155 witha 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 F1155.

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 45 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 65).

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 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).
