FIGHTER 1320- _ _ kW / 089 _ _ _ _ _ _ _ _ _ _ _

FIGHTER 1320 consists of two heat pump modulesand a CPU unit with a display to control the heat pumpand any additional heating. FIGHTER 1320 has built-in circulation pumps, making it easy to connect to theheating medium and brine circuits.

The energy from the heat source is taken up via aclosed collector system in which a mixture of waterand antifreeze circulates. The heat source can berock, soil, lake, exhaust air or other process heating.

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 heating medium circuit.

Room temperature6

FIGHTER 1320

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.

Heat production is usually controlled using the floatingcondensing principle. This means that the temperaturelevel needed for heating at a given outside tempera-ture is produced on the basis of values taken fromsensors for outside temperature and flow temperature.This adjustment is made automatically, however thebasic settings must first be made on the boiler, see thesection Room temperature > Default setting.

The basic heating is set using menu 2.1 and with theOffset heating curve 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.

Readjusting the default settings

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

When the room temperature is too high, the Curveslope value is lowered in menu 2.1 by one incre-ment.

Warm weather conditionsIf the room temperature is low, turn the Heatingcurve offset knob one step clockwise.

If the room temperature is high, turn the Heatingcurve offset knob one step anticlockwise.

Changing the room temperature manually

If you want to temporarily or permanently lower orraise the indoor temperature relative to the previouslyset temperature, turn the Heating curve offset knobanticlockwise or clockwise. One to three lines approxi-mately represents a 1 degree change in room tempera-ture.

NOTE! An increase in the room temperature may beinhibited by the radiator or floor heating thermostats, ifso these must be turned up.

In accordance with applicable regulations, heatinginstallations must undergo an installation inspectionbefore being commissioned. The inspection must becarried out by a suitably qualified person. The aboveapplies to closed heating systems. If the heat pump isreplaced, the installation must be inspected again.

The FIGHTER 1320 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 1320 must be transported and storedupright and dry.

Collectors

Inspection of the installation

The maximum length of each loop is 500 metres.The hose normally used is PEM hose 40 x 2.4 PN 6.3.The length of the collector hose varies depending onthe rock/soil conditions and on the heating system,e.g. radiators or underfloor heating.Collectors are always connected in parallel, with somemeans of adjusting the flow.For surface soil heat, the hose should be buried at adepth of about 1 metre and the distance between thehoses should be at least 1 metre. For rock heat, there must be a distance of at least 15meters between boreholes.

Several FIGHTER 1320s can be interconnected towork together. This is done by selecting one heatpump as the Master and the others as Slaves. Exter-nal units, e.g. oil boiler, are connected to the Masterunit. Each Slave is given a unique address for com-munication with the Master unit. See the sectionDescription of functions - Start up > Master/Slave.

Master / Slave

FIGHTER 1320 can be controlled up to a certain pointusing signals from an external system (e.g. DUC). Seethe section Description of functions - External control.

External control (e.g. DUC)

NOTE!The sensor and communication cables

must not be routed closed to the power cable.This applies to all external sensors and

all communication cables.When cable conduit is used for the outdoor

sensor this should be sealed to preventcondensation in the outdoor sensor capsule.

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. 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 collector system should to be labelled to showwhat antifreeze 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 installation must be carried out in accordancewith current norms and directives. FIGHTER 1320 canwork up to a return temperature of approx. 50 °C (45 °C for FIGHTER 1320-40) and an outgoing tem-perature from the heat pump of approx. 60 °C (55 °Cfor FIGHTER 1320-40). When FIGHTER 1320 is notequipped with shut off valves, these must be fitted out-side of the heat pump to assist future service work.

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/coils, a relief valve must be fitted, or some ofthe thermostats 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.

The heating medium system is filled with water untilthe required pressure is reached and then vented.

Filling the heating medium system

To fill the collector system, mix antifreeze with water inan open container which connect with filling pump andhoses as illustrated. The brine should be protectedfrom freezing down till -15 °C. ■ The valve on the main pipe between service con-

nections is closed. ■ To fill, start the pump in the filling vessel and allow

it to run until the fluid comes back in the returnhose.

■ The fluid can circulate via the mixing vessel untilfluid, without air, returns to the return hose.

■ Stop the filling pump and clean the particle filter.Start the filling pump again.

■ Open the valve on the main pipe between the ser-vice branches while the filling pump is still opera-tional (to release the air between the branches).

■ Close the valve on the return hose. ■ Pressurise the system (to max 3 bar) with the filling

pump. ■ Close the filling valve and stop the filling pump.

Filling and venting thecollector system

Pipe connections 13

FIGHTER 1320

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 (correct pres-sure and all the air removed) the heating controls canbe set at the required value.

Check that all air is removed from the collector systemby opening the venting valves. The pressure in thebrine circuit is checked with the help of pressuregauges. Filling of collector system is done by pumpingready mixed 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.

FIGHTER 1320 gives priority to hot water charging athalf power (heat pump module B) via a shuttle valve(RV). When the water heater/accumulator tank(VVB/ACK) is fully charged the shuttle valve (VXV)switches over to the heating circuit. When there is aheat requirement, module A starts first. For largerrequirements, module B takes care of the heating. Theboiler is connected automatically when the energydemand exceeds the capacity of the heat pump andthe shunt (SV-P) is activated when the temperature onthe boiler sensor (PG) is above 55 °C.If VVB/ACK is fitted with an immersion heater (IU) anda junction box (K11) the Extra hot water function canbe used. A by-pass contactor is recommended.

The compressors in FIGHTER 1320-40 are of thescroll type. These can only work in one direction ofrotation. Prolonged operations in the wrong directionof rotation can damage the compressor.To check that the direction of rotation is correct, pro-ceed as follows:Check that heat is produced immediately after thecompressor is started. This can either be done bychecking that the flow temperature on the heatingmedium (VBFA - menu 5.2.1 for compressor A andVBFB - menu 5.3.1 for compressor B) or the hot gastemperature (HGA - menu 5.2.3 for compressor A andHGB - menu 5.3.3 for compressor B) increases.On the other hand, when the temperature remainsunchanged the direction of rotation is wrong. Thesound is also different when rotation is wrong. Whenthe direction of rotation is wrong, two of the incomingphases on terminal block X9 must be switched.NOTE! A new inspection of the heating mediumpump's direction of rotation is necessary.

Rotation check FIGHTER 1320-40 The operating type must be selected for each con-

nected FIGHTER 1320. This is selected in the sub-menus to 0.2.0 and can be selected from:Off: Compressor modules A and B are not used. Nocommunication with the heat pump.Heat: Compressor modules A and B only provideheating. No shuttle valve necessary.Hot water: Compressor modules A and B only pro-vide hot water. No shuttle valve necessary.Combi: Compressor module B provides both hotwater and heating via the shuttle valve, while com-pressor module A always provides heating. The shut-tle valve should be installed to the flow line on com-pressor B.Parallel: Compressor modules A and B provide bothhot water and heating via the shuttle valve. The shut-tle valve should be connected to the common flow linefor compressors A and B.External control: Start and stop signal from externalequipment. The shuttle valve can be connected, butshould not be controlled from FIGHTER 1320.

The need of hot water production is created when thetemperature on the hot water sensor (VVG) dropsbelow the temperature set in menu 1.1. The needceases when the temperature exceeds the set tem-perature in menu 1.2.When two or more compressors are programmed forhot water charging, these are engaged and disen-gaged with 0.5 degrees minus difference for startingand stopping. That’s to say, if compressor 1 starts at50 °C and stops at 55 °C then compressor 2 starts at49.5 °C and stops at 54.5 °C i.e. each FIGHTER 1320connected for possible switching between hot waterand heating has its own shuttle valve.Hot water mode normally has priority over heatingmode. However, it is possible to set the period time andmax time for hot water production in menus 1.6 and 1.7.When in heating mode, the hot water temperature ismeasured before stopping. With less than 2 degreesto hot water start, hot water mode will start using onecompressor directly without stopping, once the heat-ing requirement is reached.

Menu 1.1 Start temperature HWThe temperature when the heat pump starts towork with the hot water production is set here.When brackets are shown, this means the highpressure pressostat has tripped during hot watercharging and FIGHTER 1320 has automaticallylowered the set temperature by the value in brack-ets. The reduction is removed when the value ischanged. The value is adjustable between 5 and55 °C. The factory setting is 45 °C.

Menu 1.2 Stop temperature HW The temperature when the heat pump stops work-ing with the hot water production is set here. Whenbrackets are shown, this means the high pressurepressostat has tripped during hot water chargingand FIGHTER 1320 has automatically lowered the

set temperature by the value in brackets. Thereduction is removed when the value is changed.The value is adjustable between 20 and 57 °C.The factory setting is 50 °C.

The function Extra hot water temporarily raises thetemperature of the hot water. The temperature israised first to an adjustable level with the compressor(menu 1.3) and then an externally mounted immersionheater takes over, if required, to increase the lastdegrees (menu 1.4).Extra hot water can either be activated via the keypadon the display, automatically at a specific time, period-ically or via an external contact. When the external contact is used, this should bepotential free and momentary. The function is activat-ed when the contact is closed for at least one second.An automatic return to the previously set functionoccurs after 12 hours.

Connection of Extra hot water

The supply to the control signal/power supply to theimmersion heater is connected to the terminal blockX6:17 (Max fuse 16 A and 250 V) and the control sig-nal/power supply out is on terminal X6:18.There is a potential free relay for the Extra hot waterfunction, which can be used for the control voltage orpower supply (max 16 A, 250 V). When you use therelay for the control voltage, the power supply can bestrapped from X6:14 to X6:17 and use X6:13 as N, butthe max. current must then be 0.4 A and the controlvoltage will be 230 V. If you take more power than thisfrom X6:14 the Base card can be overloaded.The external contact function is connected to terminalX4:3 and X4:4 on the EBV-card.

The electrical additional heater can be controlled byup to 6 relays, of which 3 are on the Base card and 3on Expansion card 1.FIGHTER 1320 delivers 230 V control signals for addi-tional heat, i. e. signals to control external relays, con-tactors etcetera, however, not to power these.In standby mode, the output ETS-3/OP (Base card)and the output ETS-6 (Expansion card 1) are voltagefed.Stepping takes place at intervals of at least 3 minutesbetween the steps when stepping up. When steppingdown the interval between steps is at least 1 minute.When HPAC is connected on the Base card andselected in menu 9.1.10, the outputs ETS-1 and ETS-2 are used to control this and accordingly can not beused to control the electrical additional heater. Withthat, the first electrical step is shifted to ETS-3.When the oil boiler is connected and Electri/Oil isselected in menu 9.1.8, the relay ETS-3 is used tocontrol the oil boiler and the electrical additionalheater then jumps over this relay when stepping.All electrical output can be force out by shorting theinput Tariff B (TB).By using the Fuse knob (100) (adjustable to 16, 20,25, 35, 50 or 63 A) the current through the ring corescan be limited. The last connected electrical output isautomatically disconnected if this happens. Extra hotwater - immersion heater (XVV) is disconnected last ofall. The setting can be checked in the menu 8.3.1.The Max electrical output knob (101) permits a limita-tion in the number of available electrical steps as partof the number of possible electrical steps according toimmersion heater type (menu 6.2.1) and relay setting(menu 6.2.2).

HPAC can either be connected to the Base card or tothe Expansion card 1. When HPAC is to be connectedto the Base card the immersion heater can be run at amaximum on one step. Control of cooling mode takes place by means of anoutdoor sensor and, when connected, a room sensor(RG 10, see the section Description of functions -Basic functions > Room control for a description of theconnection).The control of cooling to the house takes placeaccording to the set curve slope and curve offset inmenus 6.4.2 and 6.4.3. After adjustment, the housereceives the correct amount of cooling for the prevail-ing outdoor temperature. The flow temperature fromHPAC will fluctuate around the theoretical requiredvalue (value in brackets in menu 2.0). In the event ofexcess temperature, FIGHTER 1320 calculates a sur-plus in the form of degrees-minutes, which means thatthe connection of cooling production is accelerated thegreater the excess temperature that temporarily pre-vails.FIGHTER 1320 automatically switches to coolingmode when the outdoor temperature exceeds the setvalue in menu 6.4.5.Passive cooling means that FIGHTER 1320, with thehelp of the circulation pumps, circulates fluid from thesoil/rock collector in the house's distribution systemand cools the house.In the event of a large cooling requirement where pas-sive cooling is not sufficient, active cooling is engagedat the limit value set in menu 6.4.7. A compressor thenstarts and the cooling produced circulates to thehouse's distribution system and heat is circulated outto the soil/rock collector. When more compressors areavailable, these will start with a difference on the setdegree-minute setting in menu 6.4.8.

Three different cooling curves can be selected, seethe figure for a detailed description.

When the room sensor (RG 10) is connected, coolingstarts at a 1 degree over temperature in the room andthe flow line calculation then anticipates an outdoortemperature of 30 °C (when the outdoor temperatureis higher than this the actual outdoor temperature isused). Cooling is switched off when the room tempera-ture has dropped to 0.5 degrees over temperature.There is a neutral zone between cooling and heatingmodes in order to avoid self-oscillation in the heatingsystem. Heat production is only permitted up to therequired room temperature. The heating is switchedoff when the temperature is higher.The sub shunt (SV-V2) regulates in the opposite direc-tion in cooling mode in relation to the heating mode togive the correct function.

A hot water circulation pump (VVC) can be controlledto circulate the hot water by operating time or periodtime within the selected time period.The Hot water circulation pump (Hw-cp) (VVC) con-nection can be made using a T-piece docking to anelectric water heater (peak water heater). This is doneespecially on smaller installations. The docking isindependent of how the heat pump works with thedouble-jacketed water heater.When connected to a separate Hw-cp (VVC) outlet onthe double-shelled water heater (e.g. VPA) it is impor-tant that the circulation flow is accurately adjusted andthat the mixing valve on any electric peak water heateris not set too high. This can result in the stratificationin the double jacket being disturbed and the heatpump knocked out. This docking is especially used onlarge installations, which e.g. use two, double-jacket-ed water heaters. The sensor (VVG) is placed in thefirst water heater and the Hw-cp (VVC) connection ismade to the other.

The installation consists of one or more FIGHTER1320s with accumulator tanks on both the collectorand heat medium sides. Ground/rock collector(s) havethree way valves so that the accumulator tanks can beutilised as:1. Heat storage in heating mode2. Cold storage in passive cooling mode3. Heat dump in active cooling modeHeat production occurs via the accumulator tankwhere the flow line sensor (FG) is located.The circulation pump (VBP3) circulates the heatingmedium from the tank to the distribution system.The brine circulates between the brine tank and theheat pump evaporator. When the temperature is low-ered in the tank (small cooling requirement in the sys-tem) the circulation pump (CP-KO) is started toretrieve energy from the collector.When the cooling sensor (KG) requests cooling, thecirculation pump (CP-K) starts and the shunt valve(SV-K) starts regulating cooling from the brine tank. Inthe event of falling temperatures in the tank (KBack)CP-KO is started to retrieve cooling from the collector(passive cooling). When the collector is unable to pro-vide sufficient cooling the heat pump is started to pro-duce active cooling.In the event of excess heat, this is dumped to the col-lector or outdoor air via a fan battery outdoors.

Connecting cooling/heating modes withaccumulatorsNOTE! When dumping the excess heat in the outdoorair, the circulation pumps for dumping(CP-D) must be connected in parallel. The fans in theoutdoor air module can also be connected with CP-D.VXV-KV A/B must not be used.

Three way valve (VXV-KV A/B) is connected to termi-nal block X6B:1 (230 V), X6B:2 (N) and X6B:3 (NC)alternatively X6B:4 (NO).The control valve (SV-VVX) is connected to terminalblock X6B:8 (230 V reduce signal), X6B:9 (N) andX6B:10 (230 V increase signal).There are three potential free relays for functions CP-D, CP-KO & CP-K, which can be used as control volt-age or power supply (Max 6 A, 250 V). If the relay isused as control voltage the supply can be bridgedinternally from X13:4 to X6B:18, , X6B:20 and X6B:22and use X13:9 as N and receive the control signal forCP-D on X6B:19, CP-KO on X6B:21 and CP-K onX6B:23. When connected like this the max currentmust be 1 A from X13:4 and the control voltage is 230V.External supply to the control signal/power supply forCP-D is connected to terminal block X6B:18 (max fus-ing 6 A and 250 V) and the control signal/power sup-ply is on X6B:19.External supply to the control signal/power supply forCP-KO is connected to terminal block X6B:20 (maxfusing 6 A and 250 V) and the control signal/powersupply is on X6B:21.External supply to the control signal/power supply forCP-K is connected to terminal block X6B:22 (max fus-ing 6 A and 250 V) and the control signal/power sup-ply is on X6B:23.The sensors must have a good contact with the mea-suring point for best function.

Actions with operating disturbances 85

FIGHTER 1320

Cause: Incorrect setting of Curve slope and/or Off-set heating curve.

Action: Adjust the setting. Also see section Roomtemperature.

High room temperature

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 the any blown circuit andmain fuses.

Cause: Too low start temperature on the CPU-unit(34).

Action: Adjust the hot water setting, see the sectionDescription of functions - Basic functions >Hot water production.

Cause: Possible earth circuit-breaker tripped.Action: Reset the earth-fault breaker. If the earth-

fault breaker trips repeatedly - call an electri-cian.

Cause: Compressor and electric element do notheat up.

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 increase the Heatingcurve offset (knob on the front panel) orCurve slope (see section Room tempera-ture.

Cause: The compressor is not running due totripped internal 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

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 1320 can be connected

to a large number of external unitseven these should be checked.

When the switch (8) is turned to the “ ” position,the outputs for the external heating medium pumps(VBP3 and VBP4), internal heating medium pump(VBP-A) and the additional heat outputs (ETS-3/OP)and, when Expansion card 1 is connected, additionalheat output ETS-6 are activated.All control from the heat pump ceases, which meansthat when the oil boiler is connected, the shunt (SV-P)must be controlled manually. When connecting an external electrical additionalheater, a thermostat must be connected to the controlcircuit. This thermostat must be set to approximately10 °C above the maximal flow temperature (menu 2.4)to not have an effect in normal operation. However, instandby mode the thermostat’s cut-out value can belowered if necessary.Note that hot water is not produced in standby mode.

The alarm is reset when the temperature drops by 2degrees below the set max temperature.

Hi BrinealarmIncoming brine temperature (KBinA) exceeds thevalue set in menu 5.4.3.

The alarm is reset when the temperature drops by 2degrees below the set temperature.

LowbrinealarmThe temperature on the outgoing brine pump (KButAor KButB) is lower than the value set in menu 5.4.2.This may be due to:■ Too low flow on the brine.The alarm is reset when the temperature increases by2 degrees above the set temperature.

Hot gas-alarmOccurs when the temperature on the hot gas sensor(HGA or HGB) exceeds the value set in menu 5.4.4.This may be due to:

■ Defective/incorrect setting on the expansion valveThe alarm is reset when the temperature drops below60 °C.

Com. errorOccurs when communication with one of the unitsfails. This may be due to:

■ Broken cable between heat pumps.

■ Incorrect Master/Slave setting. See the sectionDescription of functions - Start up > Master / Slave.

The alarm is reset automatically within 10 minutesfrom when the cause of the fault was rectified.

In the event of an alarm the background lighting flash-es and the alarm is presented in plain text on theaffected heat pump if the screen saver is active. Thealarm status is also shown in menu 0.1.x and 5.2.0 aswell as 5.3.0. If a constant alarm occurs this is savedin the alarm log together with numerous temperaturesand output statuses (menu 9.3.0).All alarms stop the compressor affected by the fault.In the event of a constant alarm, the heat pump alarmrelay is activated (VPL) on the affected heat pump. Acommon alarm is also activated on the Master whenalarm occurs on any of the heat pumps in the system(SL).Both relays are potential free and may be loaded max.with 250 V and 2 A. The relays are drawn in the alarmpositions on the wiring diagram.The heat pump alarm (VPL) is connected to the termi-nal blocks X2:1 (signal feed), X2:2 (NC in the event ofan alarm), X2:3 (NO in the event of an alarm) on theEBV-card.Common alarm (SL) is connected to the terminalblocks X3:1 (signal fed), X3:2 (NC in the event of analarm) and X3:3 (NO in the event of an alarm) on theEBV-card.

Actions with operating disturbances88

FIGHTER 1320

Close the shut-off valves in heating medium system.Now open the drain valve (76). A little water, possiblywarm, runs out. In order to empty the entire heatingmedium side the coupling that joins the heating medi-um side and the connection on the heat pump, heatingmedium flow should be loosened a little to let in air sothat the remaining water can run out. When the heat-ing medium is empty the requisite service can be car-ried out.

When performing a service on the collector system theclosest shut off valves are closed on both sides.Draining of the fluid can then be done using the drainvalve (78).
