FIGHTER 1310 consists of two heat pump modulesand a control computer with a display to control theheat pump and any additional heat. FIGHTER 1310has built-in circulation pumps, making it easy to con-nect to the heating water and brine circuits.
The absorption of heat from the heat source (rock,ground or lake) is through a closed brine system con-taining 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. The refrigerant then vaporises andis compressed in the compressor. The refrigerant, withits increased temperature, is led into the condenserwhere it emits its energy to the heat water circuit.

Setting takes place by programming the curve slope,see the section ”Available information and settings onthe display”, and by setting the Heating curve offsetusing the Increase/reduce heat knob on the panel.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, reduce thevalue for the heating curve by one step.
Warm weather conditionsIf the room temperature is too low, turn theIncrease/reduce heat knob one step clockwise.If the room temperature is too high, turn theIncrease/reduce heat knob one step anticlockwise.
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 gets, the hotter the radiatorsor the underfloor heating pipes must be. With theFIGHTER 1310, this adjustment is done automaticallyby a control computer. Before the computer can dothis, some basic settings are required. FIGHTER 1310also offers the possibility to control two different tem-perature curves.
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 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.Room sensors can also be used as an option to com-pensate for variations in room temperature.
General
Changing 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/reduce heat knobclockwise or anticlockwise. One line approximatelyrepresents a 1 degree change in room temperature. NOTE! An increase in the room temperature may beinhibited by the radiator or floor heating thermostats, ifso these must be turned up.

Controls 7For Home Owners
The brine pump is in operation when one of the com-pressors is in operation and when the selector switchfor brine pump (40) is in the Auto position.
FIGHTER 1310 can be docked with an external unitwith its own automatic heating control system. FIGHT-ER 1310 then delivers heat up to a fixed temperaturelevel. This is known as fixed condensation. To regu-late the room temperature, see the instructions for theexternal units.
When fitted with the Hot water control accessory and,for instance, our hot water accumulator VPA, theFIGHTER 1310 can be used for hot water production.In those cases connection to the water heater hasbeen made via the accessory Hot water control andexternal immersion heaters, are installed in the waterheater the function Extra hot water can be utilised.This function increases the hot water temperaturefrom the normal 50 °C up to approx. 60 °C with thehelp of the immersion heater.
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 flow temperature (WW-out) will hover aroundthe theoretical required value (the value in brackets onthe display). For subnormal temperatures the comput-er calculates a deficit in the form of degree minutes,which results in the acceleration of heat production.The larger the subnormal temperature, the greater theheat production.
Control, normalThe heat pump’s control computer can control anexternal electric boiler/cassette in up to seven powersteps, or an external oil-fired boiler and mixingvalve.
Control, double curvesCurve 1 controls the operation of the compressors.Curve 2 controls an external mixing at lower tempera-tures. In this operating instance the supplement is limitto one step.

The FIGHTER 1310 must be installed on a firm sur-face, preferably a concrete floor or a concrete founda-tion in a boiler room or a separate equipment room.Avoid installing it in or adjacent to a sound-sensitiveroom. Wherever the unit is located, any wall thatbacks on to a bedroom should be fitted with soundinsulation.
The FIGHTER 1310 must be transported and storedupright and dry.
Transport and storage
Installation
CollectorsThe length of the collector hose varies depending onthe rock/ground conditions and on the heating system,i. e. radiators or floor heating.
FIGHTER 1310 can be docked with an external unitwith its own automatic heating control system. FIGHT-ER 1310 then delivers heat up to a fixed temperaturelevel. This is known as fixed condensation. For setting,see the section For Home Owners, Control, Setting ofmin/max temp, menu 5c respective 5d. See also theFor the installer section, control, settings, menu 10.See the instructions for the external units for 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 floatingcondensation 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.Room sensors can also be used as an option to com-pensate for variations in room temperature.
Fixed condensation
Floating condensation
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.

Channel selectionHold the Channel button down for about 7 seconds toaccess the following menus.By pressing the Channel button again you can browsethrough the display settings below to find the informa-tion you want. If a value is programmable, this is denoted by a [P](Programmable) in front of the value.If the next value cannot be set, pressing the Channelbutton displays the next menu.
Setting/ControlThe first step when changing a value is to press theIncrease button once. A cursor (line) then appearsunder the value. Now you can either increase orreduce the value with the Increase or Reduce buttons.
The electric power is controlled by the control comput-er for optimum comfort. It calculates the flow tempera-ture deficit 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. With the standard setting, the num-ber of degree-minutes must reach -500 (200 + 300)before the first step of the supplement is switched on.The last step is switched on at -700 degree-minutes.Intermediate power steps are evenly distributedbetween these two levels. The output step remainsactuated until the degree minute deficit for each stephas been compensated, which means that the flowtemperature must be as many degree minutes abovethe calculated flow level as it was previously under.This is how the average flow temperature calculatedby the computer is obtained.
GM[P] Current value for number of degree-minutes. The value can be changed in order to hasten thestart of heat production.Setting range: -3050 – +100.

It is important with some concrete floors to maintainthe right floor temperature during an initial period. Thisis so the floor dries correctly. FIGHTER 1310 has a function for this drying process.The process can be divided into two periods wherethe number of days and temperature are set forrespective periods. This setting is made on the menu20.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 1310 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%.

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 insulated toprevent corrosion. If the temperature of the brine system can fall below 0°C, the medium must be protected from frost by addingethanol spirit such as Svedol or Brineol. The mixtureshould be around 30% ethanol and the rest water. As aguideline for the volume calculation, use 1 litre of readymixed brine per meter of collector hose, (for 40 x 2.4PN 6.3 PEM hose). The brine system should to be labelled to show whatantifreeze has been used.Shut-off valves should be installed as close to the heatpump as possible. Fit a particle filter to the incomingpipe.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 additional heat exchang-er.
Pipe connections20
Pipe installation must be carried out in accordancewith current norms and directives. FIGHTER 1310 canonly operate up to a return temperature of about 50 °Cand an outgoing temperature from the heat pump ofabout 60 °C. Since FIGHTER 1310 is not fitted withshutoff valves, these must be fitted outside of the heatpump to facilitate servicing.
FIGHTER 1310
For the Installation engineer
General
Pipes are connected at the rear of the heat pump. Thenecessary safety equipment, shutoff valves (fitted asclose as possible to the heat pump), and the particlefilter and flexible hoses supplied must be fitted.When connecting to a system with thermostats on allradiators, a relief valve must be fitted, or some of thethermostats must be removed to ensure sufficientflow.The unit is designed to allow hot water production withone or two heat pump modules. However, thisrequires different pipework and a different electricalinstallation.

FIGHTER 1310 is designed so that several units canbe interconnected to satisfy large output require-ments.Module A (VP1) starts first when there is a heatingrequirement. With a further need module B (VP1)starts, then module A (VP2) etc.If the heat pumps are not capable of maintaining theright flow temperature, the boiler starts and the mixingvalve (SV) opens once the boiler reaches 55 °C. Thiscontrol option is activated automatically when the boil-er sensor (PG) is connected. The flow sensor (FG)and return sensor (RG) should be positioned on themain pipe to the radiators.When there is a demand for hot water, VP2 or, whenthere are several heat pumps interconnected, the lastheat pump (selectable full or half output) is given prior-ity for hot water charging.The accessory TSF 10 is available for this option.

When more than one FIGHTER 1310 is used, eachunit must receive signals from flow, return and outsidetemperature sensors.This is done by using the accessory TSF 10, whichmeans that only one set of temperature sensors needbe fitted at the measuring points.Separate wiring pairs should be used between TSF 10and each FIGHTER 1310.

If a temperature set back is required a make contact ina timer, for example, accessory Room thermostat RT20, should be connected to terminals 1 and 5 on ter-minal 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.
The temperature sensors for the flow FG (89) FG2(32) and the return RG (94) must make good contactwith the measuring point to provide the best perfor-mance. If a submerged tube is not available, use thecopper tube supplied on the main pipes to the heatingsystem. Secure the copper tube with 2-4 turns of alu-minium tape wound tightly. Now secure the tube usinglashing wire. Insert the temperature sensors and insu-late using two turns of thermal insulating tape.
A mixing valve, if used, is connected to terminal block(6) at terminal 13 SH+, terminal 11 SH- and terminal12 -N. The control voltage is 230 V AC, max 0.5 A.
Control voltage to external supplement is obtained bystrapping terminals 9 and 10. Phase to relays/contac-tors is connected over terminal 7 and terminal 8 is -N.The relay card’s relay contactor is potential free andbreaks max 0.5 A, 230 V AC.

Filling the heating system/heating water system
Filling and venting the brine systemTo fill the brine system, mix about 30% antifreeze withwater in an open container and connect with fillingpump and hoses as illustrated. Close the valve on themain pipe between the service connections and fill bystarting the pump in the filling vessel and let it run untilthe fluid emerges from the return hose. Then start thebrine pump (35) (see Commissioning and adjustingInternal control panel).Check that the direction of rotation of the brine pumpagrees with the arrow on the pump.The brine pump is now operational together with thefilling pump. The fluid can circulate via the mixing ves-sel until fluid, without air, returns to the return hose.
Stop the brine pump and then the filling pump. Cleanthe strainer in the particle filter. Start the filling pumpagain. Open the valve on the main pipe between theservice branches while the filling pump is still opera-tional (to release the air between the branches). Nowshut the valve on the return hose. Pressurise the sys-tem (to max 3 bar) with the filling pump. Now close thefilling valve and stop the filling pump.

■ Set the switch to 1.■ Check the settings on the control computer, and
adjust so there is a need of heating.■ Set the switch for the brine (40) and heat water
pumps (39) to position M. Set the switch for com-pressors (25) to position 0, on the inner controlpanel.
■ Check that the brine and heating water pumps arevented and if necessary help the pumps to start.Check that the direction of rotation on the heattransfer pump is right.
■ Go to the ”Brine in, Brine Out” menu. Ensure thatthe temperature corresponds with the ground/rocktemperature, which indicates the brine flow.
■ Set the compressors’ switch (25) in the 1 position.The compressors start, read the brine temperature.The difference between these temperatures oughtto be 2 –5 °C when the system is in balance, withboth compressors running. A high difference indi-cates a high brine flow.
■ Particular attention should be given to the pressurein the brine system when using the heat pump atfirst. Some topping-up may be necessary.
■ Measure the heating water temperature before andafter the condenser. The difference between thesetemperatures ought to be 5 - 10 °C. A high differ-ence could depend on a low heating water flow.
■ Set the brine pump switch (40) in the A position.
■ Set the heating water pump’s switch (39) to posi-tion A or M.
■ Check the internal venting (75) and (77).
■ Fill in the commissioning report on page 2.
■ Set the control computer to suit the needs of thebuilding.

Check that all air is removed from the brine system byopening the venting valves. The pressure in the brinecircuit is checked with the help of pressure gauges.Filling of brine system is done by pumping readymixed brine through the filling valve.Venting and filling are repeated until all the air hasbeen removed and the correct pressure (0.5 - 3 bar)has been obtained.

The heating control system of the FIGHTER 1310 iscontrolled by the outside temperature. 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 Controls 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 can beread.The Increase/Reduce heating knob (heating curve off-set) can then be set. A suitable value for floor heatingis -1 and for radiator systems -2.

Actions with operating disturbances 47For the Installation engineer
FIGHTER 1310
Cause: Incorrect setting of the Curve slope and/orIncrease/reduce heat.
Action: Adjust the setting.
High room temperature
Cause: Large amount of hot water drawn off.Action: Wait until the water heater reheats.
Cause: Compressor and/or immersion heater does notheat up.
Action: Check and replace any blown circuit and mainfuses.
Cause: Too low start temperature setting on the con-trol computer (34).
Action: Adjust the hot water setting HWstart, see Avail-able information and on-display settings menu3
Cause: Possible earth circuit-breaker tripped.Action: Reset the earth circuit-breaker, if the earth cir-
cuit-breaker trips repeatedly, call an electrician.
Cause: Compressor and electric element do not heatup.
Action: Check and replace the 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 Increase/reduce heat(knob on the front panel) or Curve slope.
Cause: The compressor is not running due to trippedinternal overheating protection.
Action: Automatic resetting after cooling for a fewhours.
Cause: Possible earth circuit-breaker tripped.Action: Reset the earth circuit-breaker, if the earth cir-
cuit-breaker trips repeatedly, call an electrician.
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 1310 can be connected
to a large number of external unitseven these should be checked.
Alarm lamp flashes and the textHP/MSalarm is displayedCause: Bad circulation in the heating water circuit.Action: Check the heating water pump (16). Open
any radiator thermostats. Check that the parti-cle 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 themotor cut-out has tripped 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 LPalarm is displayedCause: Start up of a cold installationAction: Use Electric boiler mode.
Cause: Bad circulation in brine system due to inferiorventing/low pressure or ice (if ice has formedthe brine pump (35) will be warm).
Action: Vent and top up the fluid. Wait a few hours.
Cause: Brine pump (35) malfunction.Action: Check the brine 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 brine freezing point.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 ControlInformation available on the display, menu 4.) Once the fault cause has been rectified set switch (8)to 0 and then to 1.
Ifthe operating disturbance cannot berectified by means of the above a
installation engineer should be called.
Indications
NOTE! The fault status must not be repeatedlyreset, as there is a risk of overheating
the motor windings.

FIGHTER 1310
Close the shut-off valves in heating water system.Now open the drain valve (76). A little water, possiblywarm, runs out. In order to empty the entire heatingwater side the coupling that joins the heating waterside and the connection on the heat pump ”WW-out”should be loosened a little to let in air so that theremaining water can run out. When the heating wateris empty the requisite service can be carried out.
When performing a service on the brine system theclosest shut off valves are closed on both sides.Draining of the fluid can then be done using the drainvalve (78).

■ Shut down FIGHTER 1310 by turning the switch(8) to 0.
■ Open the front 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 1310 and check whether the circu-lation pump runs.
It is usually easier to start the circulation pump withFIGHTER 1310 running, switch (8) set to 1. If helpingthe circulation pump to start is performed with FIGHTER 1310 running, be prepared for the screw-driver to jerk when the pump starts.

■ Set switch (8) to 0.
■ Close the shut-off valves outside the heat pump.
■ Drain the part of the circuit where the pump to becleaned is located, the heating water pump or thebrine pump.
■ Loosen the venting screw.
■ Remove the drive side from pump housing by loos-ening the two screws. Now dismantle the drive side(fig. A).
■ Remove the rotor unit (including pump housing) bycarefully pulling the pump rotor. If it sits firmly, itcan be loosened by knocking the rear of the shaft(fig. B).
■ Clean inside the stator can using a cleaning agent(fig. C).
■ Also clean the rotor unit using the cleaning agentand lubricate the O-ring with, for example, a soapsolution (fig. D).
■ Refit the rotor unit.
■ Refit the drive side (the flat packing is best placedon the pump housing).
■ Open the shut-off valves.
■ Set switch (8) to 1.
