FIGHTER 1220 consists of a heat pump, water heater,electrical module, circulation pumps and a control sys-tem.FIGHTER 1220 is connected to the collector andheating medium circuits.

The heat from the heat source (rock, soil, lake) is takenup via a closed collector system in which a mixture ofwater and antifreeze circulates. Groundwater can alsobe used as a heat source, but this requires an inter-vening heat exchanger.

The emits its heat to the refrigerant in the heat pump’sevaporator. It then vaporises and is compressed in thecompressor. The refrigerant, the temperature of whichhas now been raised, is passed to the condenserwhere it gives off its energy to the heating medium cir-cuit and, if necessary, to the water heater. After thecondenser there is a built-in electrical module whichcuts in if there is a high demand.

Automatic heating control systemThe 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. With theFIGHTER 1220, this adjustment is done automaticallyby a control computer. Before the computer can dothis, some basic settings are required.The heat pump is controlled by built-in sensors for flowand return heat 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 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.As an option, room sensors can also be used to com-pensate for deviations in room temperature, see menu2.5 Compensation outer. However, the correct basicsettings must be made on the boiler first, see the sec-tion Room temperature — Basic setting.

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

If you do not know the correct settings use the basicdata from the map opposite.

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 conditions

When 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 heatingcurve value is decreased in menu 2.1 by one incre-ment.

Warm weather conditionsIf the room temperature is low, increase the offsetheating curve setting by one step.

If the room temperature is high, reduce the heatingcurve offset setting by one step.

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.

The values stated on the map apply for the Curveslope.

The first value applies for low temperature * radiatorsystems. Heating curve offset is set to -2.

The value in brackets refers to floor heating systems**installed in concrete floor structures. When the systemis installed in a timber floor structure you can use thenumber before the brackets, but this value must bereduced by two units. In these cases the Heatingcurve offset is set to -1.

The map values are usually a good starting point andconcern an approximate room temperature of 20°C.The values can be adjusted later if necessary.

Examples of basic data selection:1. House with low temperature* radiator system

Markaryd = Area 10 (5). Select curve 10 on thedisplay and -2 on the Increase/reduce heat knob.

2. House with floor heating** installed in a concrete floor structure

Markaryd = Area 10 (5). Select curve 5 on the dis-play and -1 on the Increase/reduce heat knob”.

3. House with floor heating** installed in a timberfloor structure

Markaryd = Area 10 (5). Select curve 8 (10-2=8)on the display and -1 on the Increase/reduce heatknob.

* A low temperature radiator system refers to a sys-tem where the flow temperature needs to be 55 °Con the coldest day.

** Floor heating can be dimensioned very differently.Examples 2 and 3 above refer to a system wherethe flow temperature needs to be approximately35 - 40 °C resp 45 - 50 °C on the coldest day.

Basic values for the automatic heating control system

The lower values in thenorth of Sweden are dueto the lower design out-door temperature.

When there is a demand for hot water, the heat pumpgives this priority and devotes its entire output towater heating. No room heat is produced in thismode. Maximum time for hot water charging isadjustable using menu 1.3. Heating is then producedfor the remainder of the time, which is adjustable frommenu 1.2, before any further hot water charging cantake place.

If the electrical module is connected for heat produc-tion before hot water charging, one stage remainsoperative during hot water operation. Hot watercharging starts when the hot water sensor has fallento the set start temperature (25 — 50 °C), adjustableon menu 1.4. Hot water charging stops when thewater temperature has reached (30 — 58 °C),adjustable on menu 1.5. Charging is also possiblewhen the heat pump has reached its stop level forheating mode at the same time as less than 2 °Cremains to the hot water start. The purpose of this isto minimise the number of starts.

NOTE! The indicated hot water temperature is mea-sured on the lower part of the water heater jacket.This means that it is not the exact temperature of thehot water. Usually the outgoing hot water is hotterthan the indicated temperature.

For occasional higher demand for hot water, the Extrahot water function can be used to raise the tempera-ture to about 70 °C for 3 —24 hours (press the Extrahot water button once). When the electrical module isconnected for extra hot water the compressor stops.The value is adjustable between 50 — 65 °C frommenu 1.7.

In order to produce heat when the collector circuit isdisconnected, or during servicing, the heat pump canbe set to standby mode, in which case heat is pro-duced only by the immersion heater. Hot water is notproduced in standby mode. The compressor and heat transfer system are then shutoff and only the heatmedium circuit and the immersion heater are active.The temperature is controlled by the thermostat (3).To select standby mode, set the switch (8) to “ ”.

In standby mode the output is 4 kW, reconnectable to6 kW

Hot water

Standby mode

The supply of heat to the house is regulated in accor-dance with the chosen setting of the regulating curve(curve slope and offset). After adjustment, the correctamount of heat for the outside temperature is sup-plied. The heat pump’s flow temperature (menu 2.0)will hover around the theoretical required value (thevalue in brackets on the display). For subnormal tem-peratures the computer calculates a deficit in the formof degree minutes, which results in the acceleration ofheat production. The larger the subnormal tempera-ture, the greater the heat production.

There are four stages to heat production, one for theheat pump and three for the electrical module. Theoutput of the electrical module as supplied is 6 kW, but it can be rewired to give 9 kW.

General information for the installer 9For the Installer

FIGHTER 1220

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 1220 is placed on a firm base, preferably aconcrete floor or foundation. Install FIGHTER 1220with its back to an outside wall, ideally in a roomwhere noise does not matter. If this is not possible,avoid placing it against a wall behind a bedroom orother room where noise may be a problem. Irrespec-tive of the placement the wall should be sound insulat-ed. Route pipes so they are not fixed to an internalwall that backs on to a bedroom or living room.

The FIGHTER 1220 must be transported and storedupright and dry. The FIGHTER 1220 may however becarefully laid on its back when being moved into abuilding.

Transport and storage

Installation

Inspection of the installation

The unit can be used exclusively as an electric boiler,to produce heat and hot water, for example before thecollector installation is complete. For this mode, thehot water temperature is preset to 50 °C. See Set-tings, menu 9.2.4.

The brine pump normally follows the operation of theheat pump. There is a special operating mode forcontinuous operation for 10 days, followed by returnto normal mode (this may be used before stable circu-lation has been established). See Settings, menu.9.2.12.

Electric boiler mode

FIGHTER 1220 is equipped with an electric anode toprotect the enamelled hot water heater. The electricanode works automatically when FIGHTER 1220 isswitched on and is positioned behind the lower, ser-vice cover.

■ A green LED on the transformer indicates that theelectric anode is operational.

■ When the LED is not lit the anode is not receivingpower; call the installer when this can not be recti-fied.

■ When the LED flashes red, contact the installer.

For use with 40 x 2.4 PN 6.3 PEM hose.

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

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 about 1 metreand the distance between the hoses should be at least1 metre.

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

FIGHTER 1220

Factors to be taken into account when designing thecollector layout are geographical position, type ofrock/soil and cover factor of the heat 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 collector pipes in heated rooms must be insulatedagainst condensation. The level vessel (NK) must beinstalled as the highest point in the collector systemand on the incoming pipe before the brine pump. Notethat condensation may drip from the level vessel.Position the vessel so that this does not harm otherequipment.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 x2.4 PN 6.3) is used as a guide value when making thevolume calculation. Details of the antifreeze used must be shown on thelevel vessel.The collector circuit may be connected from the left orfrom the right. The lower side panels are swappedover to suit the chosen connection option. Theenclosed connecting pipes for the brine, are securedusing the clips in the punched tabs that are foldeddown on the side in question.Shut-off valves should be installed as close to theheat pump as possible. Fit the supplied particle filteron the incoming pipe.In the case of connection to an open groundwatersystem, an intermediate frost-protected circuit mustbe provided, because of the risk of dirt and freezing inthe evaporator. This requires an additional heatexchanger.

Pipe installation must be carried out in accordancewith current norms and directives. The heat pump canonly operate up to a return temperature of about 50 °Cand an outgoing temperature of about 60 °C from theheat pump. Since the FIGHTER 1220 is not fitted withshut-off valves, these must be fitted outside of theheat pump to make future servicing easier.

When installing FLM 30/40, pipes for the heat mediumand water heater and, if necessary hot water circula-tion, are routed backwards. The distance betweenFIGHTER 1220 and the wall ought to be 50 mm.

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.

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.

Centralised load control/TariffIn those cases centralised load control or tariff controlis used this can be connected to the terminal block(14) on the load monitor card (2), which is positionedbehind the upper service cover.

When the complete electrical output is to be discon-nected, a potential free contact function is connectedbetween 5 and 7 on terminal block (14), tariff A.

When the compressor is to be disconnected, a poten-tial free contact function is connected between 6 and 7on terminal block (14), tariff B.

Load monitorFIGHTER 1220 is equipped with an internal loadmonitor.

When the load monitor senses an overcurrent on oneof the phases, the immersion heater will step down theoutput until it can be connected again.

The control system must be set for the installation’smain fuse so that the load monitor can work correctly.This is done using the knob (100), marked fuse on theload monitor card (2), which is positioned behind theupper service cover. The supplied current transform-ers are connected to the terminal block’s (14) terminalsmarked 8 to 11. Terminal 11 is the common conductorfor the three current transformers. The current trans-formers are fitted in the building’s distribution box.

Cable type: unscreened LiYY, screened LiYCY. Cable cross section, at least 2 x 0.25 for cable lengths up to

Contact for changing the room tempera-tureAn external contact function can be connected toFIGHTER 1220 to change the flow temperature and indoing so change the room temperature, for example, aroom thermostat (RT10, accessory) or a timer. Thecontact should be potential free and is connected toterminals 3 and 4 on terminal block (14) on the loadmonitor card (2).When the contact is made the flow temperature ishigher or lower than the selected curve slope. The val-ue for the change is set on menu 2.5, Compensationexternal. The value is adjustable between 25 and +25.One step corresponds to one degree of the calculatedsupply temperature.

Pressure/level monitor brine (accessory)When a level monitor is required for the collectorinstallation, this can be connected to positions 16—17on terminal block 14. In order for this to be active youmust change menu 9.2.11, brine pressostat, to On.The contact shall be made during normal operating conditions.

Contact for activation of Extra hot waterAn external contact function can be connected to FIGHT-ER 1220 for activation of the Temporary extra hot waterfunction. The contactor should be potential free andmomentary and connected between terminals 3-4 on ter-minal block 4 on the left-hand connection strip on theload monitor card (2).When the contact makes for at least one second theTemporary Extra hot water function is activated.

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

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

Filling the heating medium system

Preparations

NOTE! The compressor must not be forced tostart with periods shorter that 1 start

per 15 minutes.

Fighter 1220 is equipped with a soft-starter relay (97)that limits the inrush current on the compressor to max30A.The compressor must not be forced to start with peri-ods shorter that 1 start per 15 minutes.

Soft-start relay

To fill the collector system, mix antifreeze with water,which protects against freezing down to -15 °C, in an open container and connect with fillerpump and hoses as illustrated. Close the valve on themain pipe between the service connections and fillthrough the connection under the level vessel (NK)(which has been removed) until the fluid emerges fromthe return hose. Then make the following settings onthe control panel.■ Set the switch (8) to 1.■ Select Service from menu 8.1.1.■ Switch Electric boiler mode on menu 9.2.4 to On.■ Select On in menu 9.2.12. The heat pump cannot start because EP (electric boil-er mode only) is selected. The brine pump is nowoperational together with the filling pump. The fluidcan circulate via the mixing vessel until fluid, withoutair, returns to the return hose. ■ Select Off on menu 9.2.12. Stop the filling pump and clean the particle filter. Thenstart the filling pump again. Open the valve on themain pipe between the service branches while the fill-ing pump is still operational (to release the airbetween the branches). Now close the valve by thereturn hose. Pressurise the system (to max 3 bar) withthe filling pump. Close the valve where the level ves-sel is fitted and stop the filler pump.Remove the filler hoses and refit the level vessel. Fillthe vessel about three-quarters full with the fluid. Nowshut the filling plug and open the valve under the ves-sel.■ Return to normal mode by switching Electric boiler

mode on menu 9.2.4. to Off.■ Select the required operating mode with the oper-

ating mode selector knob.

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 value.

Check the fluid level in the level vessel (85). If the lev-el has dropped, close the valve under the vessel. Youcan then fill through the connection at the top of thevessel. 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.

The siphon principle is used to empty the waterheater. This can be done either via the drain valve onthe incoming cold water pipe or by inserting a hoseinto the cold water connection.

Emptying the water heater

■ Set the switch (8) to 1.■ Check the settings on the display unit, and adjust

so there is a heating requirement.■ Select Service from menu 8.1.1.■ Switch Electric boiler mode on menu 9.2.4 to On.■ Select brine pump 10 days from menu 9.2.12 to

run the brine pump continuously for 10 days. After10 days the brine pump automatically returns tonormal operation.

■ Ensure the brine and heating medium pumps arevented and help the pumps to start if necessary.

■ Go to menu 5.0 which shows brine supply/return.Ensure that the temperature corresponds with theground/rock temperature, which indicates the brineflow.

■ Switch Electric boiler mode on menu 9.2.4 to Off.■ Select the required operating mode with the oper-

ating mode selector knob.The compressor will start, and go to menu 5.0.Read the brine temperatures. The differencebetween these two temperatures should be 2 —5°C when the system has come into balance. Ahigh difference indicates a low brine flow. A low dif-ference indicates a high brine flow.

■ Particular attention should be given to the level inthe collector system when initially using the heatpump. Some topping-up may be necessary.

■ Check the Flow temperature on menu 2.0 andReturn temperature on menu 2.7. The differencebetween these two temperatures, with floating con-densing, should be 5 — 10°C when the heat pumpheats the hot water without additional heat. A highdifference could depend on a low heat mediumflow.

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

building.

The heating control system of the FIGHTER 1220 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 Room temperature — Basic setting.

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 Offset heating curve knob is then set. A suitablevalue for floor heating is -1 and for radiator systems -2.

Action: Reset the earth circuit-breaker, if the earthcircuit-breaker trips repeatedly, call anelectrician.

Cause: Compressor and electric module do notheat.

Action: Check and replace blown circuit and mainfuses.

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

Action: Check and possibly raise the Offset heatingcurve (knob on the front panel) or Curveslope.

Cause: The compressor standstills due to theinternal 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 anelectrician.

FIGHTER 1220

NOTE! The



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 HM-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.

■ Shut down FIGHTER 1220 by turning the switch(8) to 0.

■ Open the service cover.■ Loosen the air screw with a screwdriver. Hold a

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 1220 and check whether the circu-

lation pump runs.It is usually easier to start the circulation pump withFIGHTER 1220 running, switch (8) set to 1. If helpingthe circulation pump to start is performed with FIGHT-ER 1220 running, be prepared for the screwdriver tojerk when the pump starts.
