FIGHTER 1110 consists of a heat pump module and acontrol computer with a display for operating the heatpump and additional heat (immersion heater notincluded in the basic design). FIGHTER 1110 has inte-grated circulation pumps making it easy to connect toboth the brine and heating medium circuits.The absorption of heat from the heat source (rock,ground or lake) is through a closed heat transfer sys-tem containing 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 condenserwhere it emits its energy to the heat medium circuit.

Setting takes place by programming the ”Curveslope”, see the ”Available information and settings onthe display” section, and by setting the ”Heating curveoffset” using the ”Increase/decrease” heat knob on thepanel.Initial values can be taken from the map if you do notknow which values to set, see the ”Control Basic val-ues” section.If the required room temperature is not obtained, read-justment may be necessary.NOTE! Wait one day between settings so that thetemperatures have time to stabilise.

Readjusting the settingCold weather conditions

If the room temperature is too low, increase thevalue for the heating curve by one step.If the room temperature is too high, decrease thevalue for the heating curve by one step.

Warm weather conditionsIf the room temperature is too low, turn the”Increase/decrease heat” knob one step clockwise.If the room temperature is too high, turn the”Increase/decrease heat” knob one step anticlock-wise.

The 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. FIGHTER 1110controls this automatically through a computer, butcorrect basic setting must first be made. FIGHTER1110 also offers the possibility to control two differenttemperature curves.The heat pump is controlled by built-in sensors forflow and return heat transfer fluid temperatures (col-lector). The brine return temperature can, if sorequired, be limited to a minimum (e.g. for groundwater systems).Heat production is usually controlled using 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, 2, 3 and 4). As an option,room sensors can also be used to compensate fordeviations in room temperature.

GeneralChanging the room temperature manuallyIf you want to temporarily or permanently increase orlower the indoor temperature in relation to the previ-ous heat setting turn the ”Increase/decrease heat”knob clockwise or anticlockwise. One line approxi-mately represents a 1 degree change in the room tem-perature. NOTE! An increase in the room temperature may be”inhibited” by the radiator or floor heating thermostats,if so these must be turned up.

Control 7For Home Owners

If the FIGHTER 1110 is fitted with the ”Electrical sup-plement” accessory the unit can be used solely as anelectric boiler to produce heat and hot water. This isespecially useful, for example, before the collectorinstallation is finished.

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).

FIGHTER 1110 can also be docked to an external unitwith its own heating controls. FIGHTER 1110 thensupplies heating up to a permanent temperature level.This is known as ”Fixed condensing”. To regulate the room temperature, see the instructions for theexternal units.

FIGHTER 1110 can be supplemented with ”Hot watercontrol”, VST 11 and, for example, our hot water accu-mulator VPA to produce domestic hot water. NOTE! Only the correct type of water heating cylinder,such as the VPA, may be used. DO NOTE USEOTHER TYPES OF CYLINDERS WITHOUT CON-SULTING THE MANUFACTURER.

The supply of heat to the building is controlled by thecontrol computer settings (curve slope and offset).After adjustment the correct amount of heat for thecurrent outdoor temperature is supplied. The heatpump’s flow temperature (WW-out) will hover aroundthe theoretical required value (the value in brackets onthe display). For subnormal temperatures the comput-er calculates a demand in the form of ”degree min-utes”, which results in the acceleration of heat produc-tion. The larger the subnormal temperature, thegreater the heat production.

Control, normalThe heat pump computer can control an immersionheater in three output steps if fitted, or an external oil-fired boiler and shunt valve.

Control, double curvesCurve 1 controls the operation of the compressors.Curve 2 controls an external shunt at lower tempera-tures. In this operating instance the supplement is limitto one step.

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 1110 is placed on a firm base, preferably aconcrete floor or foundation. FIGHTER 1110 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. Irrespective of the placementthe wall should be sound insulated. Route pipes sothey are not fixed to an internal wall that backs on to abedroom or living room.

The FIGHTER 1110 must be transported and storedupright and dry.

Setting up the heat pumpInspection of the installation

FIGHTER 1110 can also be docked to an external unitwith its own heating controls. FIGHTER 1110 thensupplies heating up to a permanent temperature level.This is known as ”fixed condensing”. See dockingoptions 5 and 6. For setting, see the ”For the houseowner, Control, Setting of min/max temp, displaymode 5b” section. Also see the ”For the installer sec-tion, Control, Settings, display mode 10” section.Reconnection is done according to ”Electrical connec-tion, Connecting the heat transfer fluid pump for fixedcondensing”.See the instructions for the external units on how toregulate the room temperature.The outside sensor has no function with this option,but it should be connected to prevent error messagesappearing on the display. There is no need to installthe sensor outside.

Heat production is usually controlled using the ”float-ing condensing” principle. This means that the tem-perature level needed for heating at a given outsidetemperature is produced on the basis of values takenfrom sensors for outside temperature and flow tem-perature (see docking options 1, 2, 3 and 4). As anoption, room sensors can also be used to compensatefor deviations in room temperature.

Hold the ”Channel” button down for about 7 secondsto access the following menus.Then press ”Channel” again until you reach thedesired display mode. To change the value of a dis-played variable, first press the ”Increase” button once.A cursor will appear under the value. The value cannow be changed by pressing the ”Increase” or”Decrease” buttons. Pressing the ”Channel” buttonagain moves the cursor to the value below, which insome cases can now be changed.

Control of the electrical output for best comfort is man-aged by the computer. It calculates the flow tempera-ture demand in the form of degree-minutes.

If, for example, the flow temperature has been 3degrees lower than the calculated flow temperature for 60 minutes; 3 x 60 = 180 degree minutes is registeredby the computer. Using the standard setting the num-ber of degree minutes should amount to 360 (60 +300) before the immersion heater’s first step is con-nected. After which the following steps are connectedwith a further 100 degree minutes difference. The out-put step remains actuated until the degree minutedemand for each step has been compensated, whichmeans that the flow temperature must be as manydegree minutes above the calculated flow level as itwas previously under. This is how the average flowtemperature calculated by the computer is obtained.

It is important with some concrete floors to maintain theright floor temperature during an initial period. This isso the floor dries correctly. FIGHTER 1110 has a function for this drying process.The process can be divided into two periods where thenumber of days and temperature are set for respectiveperiods. This setting is made on the channel 19.

FDP-int 1Shows the number of days at step 1.

WW-outShows the flow temperature at step 1.

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 heat transfer pipes in heated rooms must be insu-lated against condensation. The level vessel (NK)must be installed as the highest point in the heattransfer system and on the incoming pipe before theheat transfer pump. Note that condensation may dripfrom the level vessel. Position the vessel so that thisdoes not harm other equipment.If it possible for the HTF system to fall below 0 °C, ithas to be frost-protected with ethanol spirit such asSvedol or Brineol. The mixture should be around 30 %ethanol and the rest water. As a guideline for the vol-ume calculation, use 1 litre of ready mixed heat trans-fer fluid per metre of collector hose, (for 40 x 2.4 PN6.3 PEM hose). 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 incomingpipe.When connecting to an open ground water system,due to the dirt and risk for freezing in the evaporator,an intermediate frost protection circuit must beinstalled. This requires an additional heat exchanger.

Pipe installation must be carried out in accordancewith current norms and directives. FIGHTER 1110 canonly work up to a return temperature of around 50 °Cand a flow temperature from the heat pump of around60 °C. FIGHTER 1110 is not equipped with shut-offvalves so you have to install them yourself outside theheat pump to facilitate future service.

General

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).

FIGHTER 1110 prioritises charging the hot waterheater (VVB/ACK). When the preset hot water temper-ature is reached, the reversing valve switches to heat-ing. If the heat pump cannot manage to keep the cor-rect flow temperature, the oil-fired boiler starts and theshunt valve (SV) begins to open from the boiler. Thisoption is activated automatically when a boiler sensor

(PG) is connected. The flow sensor (FG) and returnsensor (RG) should be positioned on the main pipe tothe radiators.This alternative requires accessories ”OTS 10” and”VST 11”.See the ”Control with oil supplement” section for theelectrical connection.

A heat pump must not be connected without the per-mission of the electricity supplier and must be connect-ed under the supervision of a qualified electrician. If a miniature circuit breaker is used this should

have motor characteristic ”D” (compressor opera-tion). For MCB sizes see ”Technical Specifications”.

FIGHTER 1110 does not include an isolator switchon the incoming electrical supply. Therefore theinstallation must be preceded by a circuit-breaker.

If an insulation test is to be carried out in the build-ing, disconnect the heat pump.

Connect the heat pump to 230 V 1-phase, neutral +ground via a distribution board with fuses.

Connection, 1-phase

NOTE!A 1-phase connection without

electrical supplement requires pos L1and L3 to be strapped on terminal (9).

Control with oil supplement 29For the Installation engineer

FIGHTER 1110

If a temperature drop is required a make contact in atimer, for example, accessory ”Room thermostat, RT20”, should be connected to positions ”1” and ”5” onterminal block 30. The preset value is 8, this can bechanged on menu 2b.If the room thermostat, RT 20 is connected a roomsensor cannot be connected.

When starting FIGHTER 1110 the control computersenses whether the boiler sensor is installed andswitches to the oil supplement program mode. Thesupply to the oil burner is connected so that it can becontrolled via the relay from FIGHTER 1110. In situa-tions where the heat pump cannot maintain the setcontrol curve the minus value for ”degree minutes” isincreased. Once the programmed level for starting the additionalheat is reached the relay makes so the oil burner canstart. When the boiler temperature has risen toapprox. 55 °C the shunt valve starts to open. Theshunt adjusts so the true flow temperature corre-sponds with the control computer’s calculated value. If the heating requirement drops sufficiently so theadditional heat is longer required the shunt closescompletely. However, the oil boiler will be kept warmfor a further 12 hours to be prepared for any increasein the heating requirement. Note that the temperaturelevel of the oil boiler is adjusted by its existing controlequipment.

Function, oil supplement

The temperature sensors for the flow FG (89), PG (32)and the return RG (94) must make good contact withthe measuring point to provide the best performance.If a submerged tube is not available, use the coppertube supplied on the main pipes to the heating sys-tem. Secure the copper tube with 2-4 turns of alumini-um tape wound tightly. Now secure the tube usinglashing wire. Insert the temperature sensors and insu-late using two turns of thermal insulating tape.

A shunt valve, if used, is connected to terminal block(36) at position 4 ”Shunt+”, position 6 ”Shunt-” andposition 5 ”-N”. The control voltage is 230 V AC, max0.5 A.

The control voltage to the external starter used to con-nect and disconnect the oil burner is connected to ter-minal block (36) at position 3 ”TS-IN” and position 1”TS-OUT”. The relay card’s relay contactor is potentialfree and breaks max 0.5 A, 230 V AC.

Control with electrical supplement in seven steps 31For the Installation engineer

FIGHTER 1110

The control voltage for the external contactors can betaken from terminal block (36) at positions 4-6. Theimmersion heater’s first output step is controlled atposition 6. The other output steps are controlled atposition 4. The common zero for the contactors is con-nected at position 5. If only one output step is to beused the positions 4 and 6 must be connected togeth-er. The control voltage is 230 V AC, max 0.5 A. Theexternal immersion heater control should be equippedwith a temperature limiter.

Connection, Externalimmersion heater control

When the immersion heater in the existing immersionheater or electric boiler is connected the control cir-cuits for two output groups can be controlled via relaysin the heat pump. Control is binary, which means thateither the first relay is switched or only the second orboth relays are switched simultaneously. Connection of the immersion heater is controlled bothby the true flow temperature’s deviation from the con-trol computer’s calculated value and by the duration ofthe deviation with floating condensing. In theseinstances the flow line sensor integrated in the heatpump must be replaced by a temperature sensorinstalled after the immersion heater. The connection of the immersion heater is controlledby the selected fixed temperature levels with fixedcondensing.

To fill the heat transfer system, mix about 30 %antifreeze with water in an open container and con-nect with the filler pump and hoses as illustrated. Thevalve on the main line between the service connectionis shut and filling is carried out under the level vessel(NK), until the liquid comes back in the return hose.The following settings are then carried out on the con-trol panel. Set the switch to 1. Go to the ”Brine-pump, Add-drift” menu in the

service menu. Set ”Brine-pump” in pos 1 andpress ”Operating mode”. Set ”Add-drift” to 1 andpress ”Operating mode”.

The heat pump cannot start due to ”Add” operatingmode (electrical operation only). The heat transferpump is now operational together with the filling pump.The fluid can circulate via the mixing vessel until fluid,without air, returns to the return hose. Stop the heattransfer pump by setting ”Brine-pump” to ”0”. Stopthe filling pump and clean the particle filter. Then startthe filling pump again. Open the valve on the mainpipe between the service branches while the fillingpump is still operational (to release the air betweenthe branches). Now shut the valve on the return hose.Pressurise the system (to max 3 bar) with the fillerpump. Then shut the valves closest to the level vesseland stop the filling pump. Fill the level vessel with liq-uid up to around 75%. Now shut the filling plug andopen the valve under the vessel. Reset normal modeby setting ”Add” to ”0”.

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 is stable (correct pressureand all air eliminated) the automatic heating controlsystem can be set as required.

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. The pressure is raised by closing the valve on theincoming main line when the heat transfer fluid pump(HTF pump) is running and the level vessel (NK) isopen, so that liquid is drawn down from the vessel.

Readjustment, heat transfer side

Set the switch to 1. Check the settings on the control computer, and

adjust so there is a heating requirement. Go to the ”Brine-pump, Add-drift” menu in the ser-

vice menu. Set ”Brine-pump” in pos 1 and press”Operating mode”. Set ”Add-drift” in pos 1 andpress ”Operating mode”.

Ensure the heat transfer and heating mediumpumps are vented and help the pumps to start ifnecessary.

Go to the ”Brine In, Brine Out” menu. Ensure thatthe temperature corresponds with the ground/rocktemperature, which indicates the heat transfer fluidflow.

Go to the ”Brine-pump, Add-drift” menu in the ser-vice menu. Set ”Add-drift” to pos 0, the compressorstarts, and go to the ”Brine In, Brine Out” menu”.Read the heat transfer fluid temperatures. The dif-ference between these two temperatures shouldbe 2 – 5°C when the system has come into bal-ance. A high difference indicates a low heat trans-fer flow. A low difference indicates a high heattransfer flow.

Particular attention should be given to the level inthe heat transfer system when initially using theheat pump. Some topping-up may be necessary.

Read the heat medium temperatures ”WW-out”and ”WW-in”. The difference between these twotemperatures, with floating condensing, should be5 – 10 °C when the heat pump heats the hot waterwithout additional heat. A high difference coulddepend on a low heat medium flow.

Fill in the commissioning report on page 2. Set the control computer to suit the needs of the

building.

It is important with some concrete floors to maintain theright floor temperature during an initial period. This isso the floor dries correctly. FIGHTER 1110 has a function for this drying process.The process can be divided into two periods where thenumber of days and temperature are set for respectiveperiods. This setting is made on the channel 19.

FDP int 1Shows the number of days at step 1.

WW outShows the flow temperature at step 1.

FDP int 2Shows the number of days at step 2.

WW outShows the flow temperature at step 2.

It is possible to set the number of days from 1 to 10and the temperature from 15 to 50 °C. Once the dry-ing process is finished the FIGHTER 1110 automati-cally returns to normal control.If a power failure occurs during the drying process thecurrent time and temperature are stored. When thepower returns the drying process continues with thesettings that applied before the power failure. Thusthe drying process is carried out to a 100%.

Setting the heating controls 37For the Installation engineer

FIGHTER 1110

FIGHTER 1110 is equipped with outdoor temperaturecontrolled automatic heating system. This means theflow temperature is regulated in relation to the currentoutdoor temperature.The relationship between the outdoor temperatureand the flow temperature is set using the computer,see ”Control – Setting the heating”.The diagram is based on the dimensioned outdoortemperature in the area and the dimensioned flowtemperature of the heating system. When these twovalues ”meet”, the heating control’s curve slope canbe read.The ”Increase/Decrease heating” knob (heating curveoffset) can then be set. A suitable value for floor heat-ing is -1 and for radiator systems -2.

Dealing with malfunctions 49For the Installation engineer

FIGHTER 1110

Cause: Incorrect setting of the ”Curveslope” and/or”Increase/decrease heat”.

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 and

main fuses.

Cause: Too low start temperature setting on thecontrol computer (34).

Action: Adjust the hot water setting ”HW start”, see”Available information and on-display set-tings – display 3”.

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 ”Increase/decrease heat” (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.

Low hot water temperature orno hot water

Low room temperature

In the event of malfunction or operating disturbances first check the points below:

NOTE! As FIGHTER 1110 can be connectedto a large number of external units

even these should be checked.

Ifthe operating disturbance cannot be rectified by means of the above a installationengineer should be called.

Alarm lamp flashes and the text”HP/MS–alarm” is displayedCause: Bad circulation in the heating medium cir-cuit.Action: Check the heating medium pump (16). Open

any radiator thermostats. Check that theparticle filter is not blocked.

Once the fault cause has been rectified set switch (8)to ”0” and then to ”1”.If the alarm lamp still flashes the motor cut-out hastripped due to the following causes.

Cause: Dropped phase or temporary mainsdisturbance.

Action: Check the fuses.

Cause: Overloaded compressor (27).Action: Call qualified service personnel.

Cause: Mechanical fault on the compressor (27).Action: Call qualified service personnel.

Cause: Faulty motor protection (26).Action: Call qualified service personnel.

Cause: Fine-wire fuse on the relay card has blown.Action: Replace the fuse.

Alarm lamp flashes and the text”LP–alarm” is displayedCause: Start up of a cold installationAction: Use ”Electric boiler” mode.

Cause: Bad circulation in heat transfer system due toinferior venting/low pressure or ice (if ice hasformed the heat transfer pump (35) will bewarm).

Action: Vent and top up the fluid. Wait a few hours.

Cause: Heat transfer pump (35) malfunction.Action: Check the heat transfer pump.

Cause: Lack of refrigerant or other fault in the coolingcircuit.Action: Call qualified service personnel.

Cause: Blocked evaporator due to too low antifreezeconcentration.

Action: Check the freezing point of the brine.After taking action, check, on the display, that the dif-ference between "Brine In" and "Brine Out" is 2 – 5 °Cthe compressor is then operational. (See ”Control –Information available on the display”, point 4.) Once the fault cause has been rectified set switch (8)to ”0” and then to ”1”.

Indications

NOTE! The fault status must not be repeatedlyreset, as there is a risk of overheating

the motor windings.

Dealing with malfunctions 51For the Installation engineer

FIGHTER 1110

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 ”Brine In” 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 KB pump or drive side or whencleaning the pump, the shut-off valves in the heattransfer system should be closed. The hose betweenthe top of the evaporator and the KB pump is loos-ened on the evaporator. The loose hose end can nowbe bent down and emptied in a small bowl. Nowloosen the connection on ”Brine In” a little to allow airto enter so the heat pump’s heat transfer side is emp-tied completely. When the circuit is empty the requisiteservice can be carried out.

Draining, heat transfer sideDraining, heating medium side

Shut down FIGHTER 1110 by turning the switch(8) to ”0”.

Open the front cover.

Loosen the air screw with a screwdriver. Hold acloth around the screwdriver blade as a certainamount of water may run out.

Insert a screwdriver and turn the pump rotor.

Screw in the air screw.

Start FIGHTER 1110 and check whether the circu-lation pump runs.

It is usually easier to start the circulation pump withFIGHTER 1110 running, switch (8) set to ”1”. If help-ing the circulation pump to start is performed withFIGHTER 1110 running, be prepared for the screw-driver to jerk when the pump starts.
