* Accessories

The FIGHTER 1210 consists of a heat pump, waterheater, immersion heater, circulation pumps and con-trol computer with display. FIGHTER 1210 is connec-ted to the collector and heating 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 interve-ning heat exchanger.

The brine emits its heat to the refrigerant in the heatpump’s evaporator. It then vaporises and is compres-sed in the compressor. The refrigerant, the temperatu-re of which has now been raised, is passed to the con-denser where it gives off its energy to the heatingmedium circuit and, if necessary, to the water heater.After the condenser there is a built-in immersion hea-ter which cuts in if there is a high demand.

The indoor temperature depends on several factors.During the hot season, solar radiation and heat givenoff by people and equipment are sufficient to keep thehouse warm. When it gets colder outside, the heatingsystem must be started. The colder it is outside, thewarmer radiators and floor heating system must be.This adjustment takes place automatically, since theFIGHTER 1210 is equipped with a control computerfor optimal, safe operation. However, the heat pumpmust first be given the correct basic setting.

Control of the heat production is performed based onthe “floating condensing” principle, i.e. the temperatu-re level needed for heating at a specific outdoor tem-perature is produced guided by collected values fromthe outdoor and heat medium flow sensors. As anoption, room sensors can also be used to compensatefor variations in room temperature. Hot water produc-tion is given priority and controlled by means of tem-perature sensors in the water heater and an operatingpressostat.

For general information and more reliable control ofthe function there are also sensors for incoming andoutgoing brine temperatures (collector). If required, aminimum limit can be set for the outgoing brine tempe-rature (for example, with a groundwater system).

General

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/decrease heat knob on the panel.

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 thetemperatures have time to stabilise.

Readjusting the setting.

Cold weather conditionsIf 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 Increa-se/decrease heat knob one step clockwise.

If the room temperature is too high, turn the Incre-ase/decrease heat knob one step anticlockwise.

Changing the room temperature manually.

If you want to temporarily or permanently increase orlower the indoor temperature in relation to the pre-vious heat setting, turn the Increase/decrease heatknob clockwise or anticlockwise. One scale markingcorresponds to a change of about one degree in theroom temperature.

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

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. When the demand for hot water is high, themaximum time for water heating is approximately 45minutes. After this, room heating is produced for 15minutes before further water heating can take place.

If the immersion heater is activated for heat produc-tion before hot water charging, one step remains ope-rative during hot water operation. Hot water chargingstarts when the hot water sensor has fallen to the setstart temperature (30 – 49 °C). In order to reach themaximum hot water temperature, hot water chargingis stopped by the operating pressostat on the heatpump. In addition, charging can take place when theheat pump has reached its stop-level for heatingmode at the same time as less than 2 °C is neededbefore the start of hot water. The purpose of this is tominimise 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 of hot water, the Extrahot water function can be used to raise the temperatu-re to about 60 °C for 24 hours (press the Extra hotwater button once”). The immersion heater is used toraise the temperature above 50 °C.

There is also a function to periodically increase thehot water temperature (press the Extra hot water but-ton twice). In this mode, the temperature is raisedtemporarily by means of the immersion heater toabout 60°C for a period of between 1 and 90 days.

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 suppli-ed. The heat pump’s flow temperature (WW-out) willhover around the theoretical required value (the valuein brackets on the display). For subnormal temperatu-res the computer calculates a demand in the form ofdegree-minutes, this results in the acceleration of heatproduction. The larger the subnormal temperature, thegreater the heat production.

There are four step to heat production, one for theheat pump and three for the immersion heater. Theoutput of the electrical unit as supplied is 6 kW (FIGHTER 1210–4, 3 kW) but it can be rewired to give9 kW.

In order to produce heat when the collector circuit isdisconnected, or during servicing, the heat pump canbe set to spare mode, in which case heat is producedonly by the immersion heater. Hot water is not produ-ced in spare mode. The compressor and collector sys-tem are then shutoff and only the heating medium cir-cuit and the immersion heater are active. The tempe-rature is controlled by the thermostat (3). To selectspare mode, set the switch (8) to R.

General information for the installer 11For the Installer

FIGHTER 1210

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 to clo-sed heating systems. If the heat pump is replaced, theinstallation must be inspected again.

FIGHTER 1210 is placed on a firm base, preferably aconcrete floor or foundation. Install FIGHTER 1210with its back to an outside wall, ideally in a room whe-re noise does not matter. If this is not possible, avoidplacing it against a wall behind a bedroom or otherroom where noise may be a problem. Irrespective ofthe placement the wall should be sound insulated.Route pipes so they are not fixed to an internal wallthat backs on to a bedroom or living room.

FIGHTER 1210 should be transported and stored ver-tically in the dry. The FIGHTER 1210 may however becarefully laid on its back when being moved into a buil-ding.

Inspection of the installation

The length of the collector hose varies depending onthe rock/ground conditions and on the heating system,i. e. radiators or floor heating.

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 14”.

The brine pump (35) normally follows the operation ofthe heat 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, menu14”.

Control of the immersion heater for best comfort ismanaged by the computer. It calculates the flow tem-perature deficit in the form of degree-minutes.

If, for example, the heat medium flow temperature hasbeen 3 degrees lower than the calculated heat medi-

um flow temperature for 60 minutes; 3 x 60 = 180degree-minutes is registered by the computer. Usingthe standard setting the number of degree-minutesshould amount to 360 (60 + 300) before the immersionheater’s first step is connected. After which the follo-wing steps are connected with a further 100 degreeminutes difference. The output step remains actuateduntil the degree-minute demand for each step hasbeen compensated, which means that the heat medi-um flow temperature must be as many degree-minu-tes above the calculated flow level as it was previouslyunder. This is how the average heat medium flow tem-perature calculated by the computer is obtained.

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.

Since the temperature in the collector system may fallbelow 0 °C, the system must be protected from free-zing by mixing, for example, a proprietary ethanolsuch as Svedol or Brineol, with water. The mixtureshould be around 30% ethanol and the rest water. Asa guide to working out the amount required, one litreof mixed brine is used per metre of collector hose (thisapplies to PEM-hose 40 x 2.4 PN 6.3).

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. The enclo-sed connecting pipes for the brine, are secured usingthe clips in the punched tabs that are folded down onthe 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 1210 is not fitted withshut-off valves, these must be fitted outside of theheat pump to make future servicing easier.

During assembly of FLM 30 the pipes for the heatmedium and water heater and possibly hot water cir-culation are diected backwards. The distance bet-ween FIGHTER 1210 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.

For the Installer

■ If an insulation test is to be carried out in the buil-ding, disconnect the heat pump.

■ The heat pump is connected on terminal (9) to 400V 3-phase, neutral + earth via a distribution boardwith fuses.

■ FIGHTER 1210 does not include an isolator switchon the incoming electrical supply. An isolatorswitch should therefore be installed before theinstallation.

■ A heat pump must not be connected without thepermission of the electricity supplier and must beconnected under the supervision of a qualifiedelectrician.

■ If a miniature circuit breaker is used this shouldhave motor characteristic “D” (compressor opera-tion). For fuse ratings, see Technical data.

■ Disconnection of the immersion heater is achievedby connecting an external potential-free make (NO)contact to terminal (30) pos 1. and 2.

■ Disconnection of the immersion heater, with thepossibility to use Extra hot water while the power isdisconnected is achieved by connecting an exter-nal potential-free make (NO) contact to terminal(30) pos 1. and 3.

■ Disconnection of the immersion heater by step isachieved by connecting the accessory “Load moni-tor EBV 200” to terminal (30) pos 1. and 2.

■ Connections pos 2 and 3 should be connectedtogether to block the compressor as well as thesupplement. Connection pos 1 is then connected toeach side of the contact that controls the blocking.

FIGHTER 1210 has an immersion heater which isconnected for 6 kW on delivery (FIGHTER 1210–4, 3 kW immersion heater output). The output of theimmersion heater as supplied is 6 kW (FIGHTER1210–4, 3 kW) but it can be rewired to give 9 kW. See“Wiring diagram”

■ Install the outdoor sensor in the shade on a wallfacing north or north-west, so it is not exposed tothe morning sun. The sensor is connected with twowires to positions “7” and “8” on the relay board’s(29) terminal (30). The minimum wire cross sectionshould be 0.4 mm2 up to lengths of 50 metres, forexample EKKX or LiYY. Relay board is placedbehind the control computer.

■ If the outdoor sensor wire runs close to power wire,shielded wire must be used.

FIGHTER 1210

For the Installer

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

To fill the collector system, mix about 30% antifreezewith water 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.■ Go to the Brine-pump menu, Add-drift in the ser-

vice menu. Set Brine-pump to 1 and press Opera-ting mode. Set Add-drift to 1 an press Operatingmode.

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

The heat pump cannot start as the operating mode“EB” (electric boiler mode only) is selected. The brinepump 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. Now stop thebrine pump by setting Brine-pump to “0”. 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 fil-ling pump is still operational (to release the air bet-ween the branches). Now close the valve by the returnhose. Pressurise the system (to max 3 bar) with the fil-ler pump. Close the valve where the level vessel is fit-ted 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. Reset normal mode by setting EB 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. To raise the pressure, close the valve on the incomingmain pipe when the brine pump is running and thelevel vessel is open, so that water is drawn in from thevessel.

The siphon principle is used to empty the water hea-ter. This can be done either via the drain valve on theincoming cold water pipe or by inserting a hose intothe cold water connection.

■ Set the switch (8) to 1.■ Check the settings on the control computer, and

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

vice menu. Set the Brine-pump to position 1 andpress Operating mode. Set Add-drift in position 1and press Operating mode.

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

■ Go to the Brine In, Brine Out menu. Ensure thatthe temperature corresponds with the ground/rocktemperature, which indicates the brine flow.

■ Go to the Brine-pump menu, Add-drift in the ser-vice menu. Set Add-drift to 0, the compressorstarts, and go to the Brine In, Brine Out menu.Read the brine fluid 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 a few days after start-up.Some topping-up may be necessary.

■ Read the heat medium temperatures WW-out andWW-in. The difference between these two tempe-ratures, with floating condensing, should be 5 –10°C when the heat pump heats the heating 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.

Setting the automatic heating control system 21For the Installer

FIGHTER 1210

FIGHTER 1210 is equipped with an outdoor tempera-ture controlled automatic heating system. This meansthe heat medium flow temperature is regulated in rela-tion to the current outdoor temperature.

The relationship between outdoor temperature andflow temperature is set using the control computer;see “Control” “Setting the heating”.

The diagram is based on the dimensioned outdoortemperature in the area and the dimensioned heatmedium flow temperature of the heating system.When these two values meet, the heating control’scurve slope can be read.

The Increase/decrease heat knob (heating curve off-set) is then set. A suitable value for floor heating is -1and for radiator systems -2.

NOTE! The

product’s serial numbershould always be stated with all

correspondence with NIBE.689_ _ _ _ _ _ _ _ _ _ _

Cause: Incorrect setting of the Curve slope and/orIncrease/decrease heat.

Action: Adjust the setting.

Cause: Large amounts of hot water were used.

Action: Wait until the water heater reheats.

Cause: Compressor and/or immersion heater does not heat up.

Action: Check and replace blown circuit and mainfuses.

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

Action: Adjust the start temperature setting.

Cause: Possible earth circuit-breaker tripped.

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

Cause: Compressor and immersion heater do not heat.

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 Increase/decreaseheat (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.

Low hot water temperature or no hot water

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

High room temperature

Low room temperature

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

The alarm lamp flashes and the text“HP/MSalarm” is displayedCause: Bad circulation in the heating medium

circuit.Action: Check the heating medium pump (16).

Possibly open the radiator thermostats.Check that the particle filter (63) is notclogged.

Once the fault cause has been 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 main power disturbance.

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

Cause: Fuse on the relay board has blown.Action: Replace the fuse.

The alarm light flashes and the text:“LPalarm” is displayedCause: Start up of cold installationAction: Use Electric boiler mode.

Cause: Bad circulation in collector system due toinferior venting/low pressure or ice (if icehas formed the brine pump (35) will bewarm).

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

Cause: Brine pump (35) not running.Action: Check the brine pump.

Cause: Lack of refrigerant or other fault in the cooling unit.

Action: Call qualified service personnel.

Cause: Iced evaporator due to too low antifreezeconcentration

Action: Check the freezing point of the brine.

After taking action, check that the difference on thedisplay between Brine In and Brine Out is 2 – 5 °Cwhen the compressor is running. (See ControlInformation available on the display, menu 4).Once the fault cause has been, set switch (8) to “0”and then to “1”.In the event of a temperature sensor error, this isindicated on the display, e.g. “out error”NOTE!

The fault status must not berepeatedly reset, as there is a risk

of overheating the motorwindings.

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 the hea-ting medium side and the connection on the heatpump WW-out 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 (35) or drive side orwhen cleaning the pump, the shut-off valves in theheat transfer system should be closed. The hose bet-ween the evaporator’s upper section and the brinepump is loosened on the evaporator. The loose hoseend can now be bent down and emptied in a smallbowl. Now loosen the connection on Brine In a little toallow air to enter so the heat pump’s collector side isemptied completely. When the circuit is empty therequisite service can be carried out.

■ Shut down FIGHTER 1210 by the switch (8) to “0”.■ Open the front cover.■ Loosen the venting 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.■ Tighten the venting screw.■ Start FIGHTER 1210 and check whether the circu-

lation pump runs.It is usually easier to start the circulation pump withFIGHTER 1210 running, switch (8) set to “1”. If hel-ping the circulation pump to start is performed withFIGHTER 1210 running, be prepared for the screwdri-ver to jerk when the pump starts.

Check the anode within a year. And then regularly in relation to its use. When the anode is new it has a diameter of approx. 34 mm. When this has decreased (in its most used area) to under 10 mm theanode is consumed and must be replaced.

If anode consumption has not occurred after a fewyears, this may be due to inferior conductivity in thewater and a water analysis is recommended.

Checking the sacrificial anode (enamel)

There is a sacrificial anode mounted on a flange at thetop of the hot water heater. Anode replacement takesplace as follows:■ Remove the heat pump's circuit fuses in the distribu-

tion cabinet.■ Empty the hot water heater, see the chapter “Com-

missioning and adjustment” – “Emptying the waterheater”

■ Dismantle the cover plate (58) as illustrated.■ Dismantle the flange.■ Replace the anode mounted on the flange.■ Re-assemble in the reverse order.

Replacing the sacrificial anode (enamel)
