FIGHTER 1120 consists of a heat pump, circulationpumps and a control system for the heat pump andany additional heat (an immersion heater is not includ-ed in the basic design). FIGHTER 1120 has built-in circulation pumps, makingit easy to connect to the heating medium and collectorcircuits.The absorption of heat from the heat source (rock,ground or lake) is through a closed collector systemcontaining water mixed with antifreeze.

Ground water can also be used as a heat source. Thisrequires an intermediate heat exchanger.The brine emits its heat to the refrigerant in the heatpump's evaporator. It then vaporises and is com-pressed in the compressor. The refrigerant, with itsincreased temperature, is led into the where it emitsits energy to the heat medium circuit.

GeneralThe indoor temperature depends on several factors.Sunlight and heat emissions from people and house-hold machines are normally sufficient to keep thehouse warm during the warmer parts of the year.When it gets colder outside, the heating system mustbe started. The colder it is outside, the warmer radia-tors and floor heating system must be. The heat pump is controlled by built-in sensors forflow and return brine temperatures (collector). Brinereturn temperatures can, if so required, be limited to aminimum (e.g. for ground water systems).Heat production is usually controlled on the “floatingcondensing” principle. This means that the tempera-ture level needed for heating at a given outside tem-perature is produced on the basis of values taken fromsensors for outside temperature and flow temperature(see docking options 1 - 3). This adjustment is madeautomatically, however the basic settings must first bemade on the boiler, see the section “Settings” -“Default setting”. Room sensors can also be used as an option to com-pensate for variations in room temperature, see menu6.1 “Room compensation”.

The basic heating is set using menu 2.1 and with the“Heating curve offset” knob.

If the required room temperature is not obtained, read-justment may be necessary.

NOTE! Wait one day between settings so that the tem-peratures have time to stabilise.

Readjustment of basic settings.

Cold weather conditionsWhen the room temperature is too low, the “Heatingcurve” value is increased in menu 2.1 by one incre-ment.

When the room temperature is too high, the “Heat-ing curve” value is decreased in menu 2.1 by oneincrement.

Warm weather conditionsIf the room temperature is low, increase the “Heat-ing curve offset” setting by one step.

If the room temperature is high, reduce the “Heatingcurve offset” setting by one step.

The heating control system on the FIGHTER 1120 iscontrolled by the outside temperature. This means theflow temperature is regulated in relation to the currentoutdoor temperature.The relationship between the outside temperature andthe flow temperature is set using the control system,also see section “Heating control system - Basic set-ting”.The diagram is based on the dimensioned outdoortemperature in the area and the dimensioned supplytemperature of the heating system. When these twovalues “meet”, the heating control's curve slope canbe read. This is set on menu 2.1 “Curve coefficient”.

FIGHTER 1120

If the FIGHTER 1120 is fitted with the accessory ETS12 / ETS 121 the unit can be used solely as additionalheat (electric boiler) to produce heat and hot water.This is especially useful, for example, before the col-lector installation is finished. Changing the “Electric boiler” is done in menu 9.2.4.NOTE! Select “Off” to deactivate only additionalheat and select the required operating mode usingthe operating mode button.

The brine pump normally follows the operation of theheat pump. There is a special operating mode for con-tinuous operation for 10 days, followed by return tonormal mode (used before stable circulation has beenestablished).The setting is made on menu 9.2.12 “Brinepump 10days”.

If required FIGHTER 1120 can be docked to an exter-nal unit with its own heating controls. FIGHTER 1120then delivers heat up to a fixed temperature level. Thisis known as “fixed condensing”. To regulate the room temperature, see the instructions for the externalunits.

Not connected from the factory, requires the accesso-ry ETS 12 / ETS 121.

FIGHTER 1120 can be complemented with “Domestichot water operation” and, for example, our VPA hotwater accumulator to produce domestic hot water.

The supply of heat to the building is controlled by thecontrol system settings (curve slope and offset). Afteradjustment the correct amount of heat for the currentoutdoor temperature is supplied. The flow line temper-ature of the heat pump (heating medium flow) will huntaround the theoretically required value (the value inbrackets on the display). For subnormal temperaturesthe control system calculates a heating deficit in theform of “degree-minutes”, which means that heatingproduction is accelerated. The larger the subnormaltemperature, the greater the heat production.The heat pump's control system can control an immer-sion heater in a maximum of seven output steps if fit-ted, or an external oil-fired boiler and shunt valve.

General information for the installer10

FIGHTER 1120

Current regulations require the heating installation tobe inspected before it is commissioned. The inspec-tion must be carried out by a suitably qualified personand should be documented. The above applies toclosed heating systems. If the heat pump is replaced,the installation must be inspected again.

FIGHTER 1120 is placed on a firm base, preferably aconcrete floor or foundation. FIGHTER 1120 shouldbe setup with its rear against an outer wall in ascullery or similar type of room to eliminate noiseproblems. If this is not possible, avoid placing itagainst a wall behind a bedroom or other room wherenoise may be a problem. Wherever the unit is located,any wall that backs on to a bedroom should be fittedwith sound insulation. Route pipes so they are notfixed to an internal wall that backs on to a bedroom orliving room.

The FIGHTER 1120 must be transported and storedupright and dry.

Transport and storage

Installation

Guideline values for collectors

Inspection of the installation

For use with 40 x 2.4 PN 6.3 PEM hose.

The length of the collector hose varies dependingon the rock /soil conditions and on the heating sys-tem, i.e. radiators or floor heating.Max length per collector should not exceed 400 m.

Where there is more than one collector, they must beconnected in parallel, with a means of adjusting theflow.

The hose should be buried at a depth of about1 metre and the distance between the hoses shouldbe at least 1 metres for surface soil heat.

For several bore holes, the distance between theholes must be at least 15m.

If required FIGHTER 1120 can be docked to an exter-nal unit with its own heating controls. FIGHTER 1120then delivers heat up to a fixed temperature level. Thisis called “fixed condensing”. See docking option 4. Toset the correct parameters for fixed condensing see“Docking - option 4”. The heat medium pump does notneed to be changed.See the instructions for the external units for how toregulate the room temperature.The outside temperature sensor has no function withthis option, but it should be connected to prevent errormessages appearing on the display. There is no needto install the sensor outside.

Heat production is usually controlled on the “floatingcondensing” principle. This means that the tempera-ture level needed for heating at a given outside tem-perature is produced on the basis of values taken fromsensors for outside temperature and flow temperature(see docking options 1 - 3).

When dimensioning the collector, consideration mustbe given to the geographical location, type of rock andground and the degree of coverage provided by theheat pump. When installing the collector hose ensure it rises con-stantly towards the heat pump to avoid air pockets. Ifthis is not possible, install high points to vent the air.All brine pipes in heated rooms must be insulatedagainst condensation. The level vessel (NK) must beinstalled as the highest point in the collector system andon the incoming pipe before the brine pump. Note thatcondensation may drip from the level vessel. Positionthe vessel so that this does not harm other equipment.As the temperature of the collector system can fallbelow 0 °C it must be protected against freezing downto -15 °C. One litre of ready mixed brine per meter ofcollector hose (applies when using PEM-hose 40 x 2.4PN 6.3) is used as a guide value when making the vol-ume calculation. The level vessel must be marked to show the type ofantifreeze used.Shut-off valves should be installed as close to the heatpump as possible. Fit a particle filter to the incoming pipe.In the case of connection to an open groundwater sys-tem, an intermediate frost-protected circuit must beprovided, because of the risk of dirt and freezing in theevaporator. This requires an extra heat exchanger.

Pipe connections 11

FIGHTER 1120

Pipe installation must be carried out in accordancewith current norms and directives. FIGHTER 1120 canoperate up to a return temperature of about 58* °Cand an outgoing temperature from the heat pump ofabout 70* °C. The compressor produces up to 65* °C,the rest is obtained using additional heating.* Applies to 5 kW 1-phase, 6 kW 3-phase 3 x 400 V, 8

kW 3-phase 3 x 400 V and 10 kW 3-phase 3 x 400 V.The other heat pumps has a max return temperatureof approximately 50 °C and an outgoing max tempera-ture from the heat pump of approximately 60 °C.Since FIGHTER 1120 is not fitted with shut-off valves,these must be fitted outside of the heat pump to facili-tate servicing.

General

Pipe connections (collector)

The heating medium pump (VBP) runs at the sametime as the brine pump (KBP) with fixed condensing(docking option 4) in auto mode.

Heating medium pump

NOTE!The pipe system needs to be flushed

out before the heat pump is connectedso that debris cannot damage

component parts.

Pipe connections for the heat medium side are madeat the top. All required safety devices, shut-off valves(as close to the heat pump as possible), and particlefilter (supplied) are fitted.You should fit either an overflow valve or removesome of the thermostats when connecting to systemswith thermostats on all the radiators (coils).

Centralised load control/TariffIn those cases centralised load control or tariff controlis used this can be connected to the terminal block X1on the load monitor card (2), which is positionedbehind the upper service cover.

Tariff A, the whole electrical output is disconnected.Connect a potential free contact function to terminalsX1:5 and X1:7.

Tariff B, the compressor is disconnected. Connect apotential free contact function to terminals X1:6 andX1:7.

Tariff A and Tariff B can be combined.

A made contact results in the electrical output beingdisconnected.

Load monitorNOTE! No function in a 1-phase installation.When many power consumers are connected in theproperty at the same time as the immersion heater isoperating, there is a risk of the property's main fusetripping. The heat pump is equipped with an integrat-ed load monitor that controls the electrical steps onthe immersion heater.

When the phase current is so high that there is a riskof the main fuses tripping, the load monitor reducesthe immersion heater output until the risk of the mainfuses tripping has passed. When the general powerconsumption drops, the immersion heater will be con-nected again.

A current transformer should be installed on eachincoming phase conductor in to the distribution box tomeasure the current. The distribution box is an appro-priate installation point.

Connect the current transformers to a multi-corecable in an enclosure next to the distribution box. Useunscreened multi-core cable of at least 0.50 mm2,from the enclosure to the heat pump.

The cable is connected in the heat pump to the EBV-card on terminals X1:8 - X1:11. X1:11 is the commonterminal block for the three current transformers.

The size of the property's main fuse is set using theknob (100) on the EBV-card. The setting can bechecked in the menu 8.3.4.

Before starting up the system, check that the heating,collector and hot water circuits are full and thoroughlyvented. Check the pipe system for leakage.

Preparations

Fill the heating medium system with water to therequired pressure and vent the system.

Filling the heating medium system

When filling the collector system mix the water withantifreeze in an open container. The mixture shouldbe protected against freezing down to about -15 °C.The brine is filled by connecting a filling pump.

1. Check the collector system for leakage.

2. Connect the filling pump and return line on the col-lector system's service connections as shown infigure.

3. Close the valve under the level vessel.

4. Close the valve between the service connections.

5. Open the valves on the service connections.

6. Start the filling pump, and fill until there is fluid inthe return pipe.

7. Turn the heat pump's switch (8) to 1.

8. Select “Service” in menu 8.1.1.

9. Select “On” in menu 9.2.4.

10. Select “On” in menu 9.2.12. The filling pump andthe heat pump's brine pump are now operational.The fluid should circulate via the mixing containeruntil it emerges from the return hose without beingmixed with air.

11. Select “Off” in menu 9.2.12.

12. Stop the filling pump and clean the particle filter.

13. Start the filling pump, open the valve between theservice connections.

14. Close the valve on the service connection's returnline. Now pressurise the system (to max 3 bar)with the filling pump.

15. Close the valve on the service connection closestto the level vessel.

16. Stop the filling pump.

17. Fill the level vessel with liquid up to around 2/3.

18. Open the valve below the level vessel.


20. Select the auto operating mode using theoperating mode button.

The compressor in FIGHTER 1120-12 kW 3 x400 V isof the scroll type. It can only operate in one directionof rotation. Operating in the wrong direction candamage the compressor.

The direction of rotation is checked as follows:■ Set the switch to 1.

■ Check the hot gas temperature in menu 5.11. Thetemperature should increase by 10 °C within 30seconds from compressor start.

■ If the temperature remains the same, the directionof rotation is incorrect. The noise produced is alsodifferent when rotating in the incorrect direction.

- Set the switch to 0 and cut the mainpower supply.

- Swap the two incoming phases on theterminal block for incoming electricity, -X9.

- Set the switch to 1 and check the rotationagain.

The compressor in FIGHTER 1120-15, 17 kW 3 x400 V is of the scroll type. It can only operate inone direction of rotation. Operating in the wrongdirection can damage the compressor.

The direction of rotation is checked as follows:■ Set the switch to 1.

■ Wait until the symbol for the compres-sor lights up in the display.

■ Check that the compressor is operating.

■ If the compressor is not operating and the symbolfor the compressor is lit, there is a phase sequenceerror. The phase sequence monitor (164) also indi-cates this; see section “Electrical connection”.

- Set the switch to 0 and cut the mainpower supply.

- Swap the two incoming phases on theterminal block for incoming electricity, -X9.

Air is initially released from the hot water and ventingmay be necessary. If bubbling sounds can be heardfrom the heat pump, the entire system requires furtherventing. When the system has stabilised (correctpressure and all the air removed) the heating controlscan be set at the required values.

Check the fluid level in the level vessel (85). If thelevel has dropped, close the valve under the vessel.You can then fill through the connection at the top ofthe vessel. After filling, open the valve again. To raise the pressure, close the valve on the incomingmain pipe when the brine pump (KBP) is running andthe level vessel (NK) is open, so that water is drawn infrom the vessel.

Alarm LPThis information is shown when the low pressureswitch in FIGHTER 1120 has tripped. The compressoris blocked and FIGHTER 1120 switches to wintermode, only additional heat without hot water.

This may be due to: ■ Bad circulation in collector system due to inferior

venting/low pressure or ice (if ice has formed thebrine pump (35) will be warm).

■ Brine pump (35) malfunction.■ Iced evaporator due to too low antifreeze concen-

tration.■ Leakage in the collector circuit.

The background lighting on the display flashes with analarm and the following information is shown depend-ing on the fault. An alarm log is created with eachalarm containing a number of temperatures, times andthe status of outputs. The four alarms are saved onmenu 9.5.0 - 9.8.0.

Cause: Incorrect setting of “Curve slope” and/or“Heating curve offset”.

Action: Adjust the setting.

Cause: Large amount of hot water drawn off.Action: Wait until the water heater reheats.

Cause: Compressor and/or immersion heater doesnot heat up.

Action: Check and replace any blown circuit andmain fuses.

Cause: Too low start temperature setting on thecontrol system.

Action: Adjust the start temperature setting in menu1.4.

Cause: Possible earth circuit-breaker tripped.Action: Reset the earth circuit-breaker, if the earth

circuit-breaker trips repeatedly, call an elec-trician.

Cause: Compressor and immersion heater do notheat up.

Action: Check and replace any blown circuit andmain fuses.

Cause: The compressor does not start because of atoo low value set on the heating curve.

Action Check and possibly raise the “Heating curveoffset” (knob on the front panel) or “Curveslope”.

Cause: The compressor standstills due to the inter-nal overheating protection tripping.

Action: Automatic resetting after cooling for a fewhours.

Cause: Possible earth circuit-breaker tripped.Action: Reset the earth circuit-breaker, if the earth

circuit-breaker trips repeatedly, call an electri-cian.

Ifthe operating disturbance cannot be rectified by means of the above,an installation engineer should be called.

Close the shut-off valves in heating medium system.Now open the drain valve (76). A small amount ofwater runs out, however, to fully empty the heatingmedium side requires the connector that joins theheating medium side and the connection on the heatpump “VB-flow” to be loosened a little to allow air toenter so the remaining water can run out. When theheating medium is empty the requisite service can becarried out.

When replacing the brine pump or drive side or whencleaning the pump, the shut-off valves in the collectorsystem should be closed. The hose between the topof the evaporator and the brine pump is loosened onthe evaporator. The loose hose end can now be bentdown and emptied in a small bowl. Now loosen theconnection on “Brine-in” a little to allow air to enter sothe heat pump's collector side is emptied completely.When the circuit is empty the requisite service can becarried out.

Draining, collector sideDraining, heat medium side

■ Shut down FIGHTER 1120 by turning the switch(8) to “0”.

■ Open the service cover.

■ Loosen the venting screw with a screwdriver. Holda cloth around the screwdriver blade as a certainamount of water may run out.

■ Insert a screwdriver and turn the pump rotor.

■ Screw in the venting screw.

■ Start FIGHTER 1120 and check whether the circu-lation pump runs.

It is usually easier to start the circulation pump withFIGHTER 1120 running, switch (8) set to “1”. If help-ing the circulation pump to start is performed withFIGHTER 1120 running, be prepared for the screw-driver to jerk when the pump starts.
