FIGHTER 1240 consists of a heat pump, water heater, electrical module, circulation pumps and a control sys-tem. FIGHTER 1240 is connected to the collector and heating medium circuits.

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

The brine emits its heat to the refrigerant in the heat pump’s evaporator. It then vaporises and is com-pressed in the compressor. The refrigerant, the tem-perature of which has now been raised, is passed to the condenser where it gives off its energy to the heat-ing medium circuit and, if necessary, to the water heat-er. After the condenser there is a built-in electrical module which cuts in if there is a high demand.

The indoor temperature depends on several factors. Sunlight and heat emissions from people and house-hold machines are normally sufficient to keep the house warm during the warmer parts of the year. When it gets colder outside, the heating system must be started. The colder it is outside, the warmer radiators and floor heating system must be.The heat pump is controlled by built-in sensors for flow and return brine temperatures (collector). Brine return temperatures can, if so required, be limited to a mini-mum (e.g. for ground water systems).Heat production is usually controlled using the floating condensing principle. This means that the temperature level needed for heating at a given outside tempera-ture is produced on the basis of values taken from sensors for outside temperature and flow temperature. As an option, room sensors can also be used to com-pensate for deviations in room temperature, see menu 6.1 Room compensation. However, the correct basic settings must be made on the boiler first, see the section Settings — Basic set-ting.

The basic heating is set using menu 2.1 and with the Offset 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.

Readjustment of basic settings. Cold weather conditions When the room temperature is too low, the Curve

coefficient value is increased in menu 2.1 by one increment.

When the room temperature is too high, the Curve coefficient value is lowered in menu 2.1 by one increment.

Warm weather conditions If the room temperature is low, increase the heating

curve offset setting by one step.

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

The heating control system of the FIGHTER 1240 is controlled by the outside temperature. This means the supply temperature is regulated in relation to the cur-rent outdoor temperature.

The relationship between the outside temperature and the flow temperature is set using the control system, also see section Settings — Basic setting.

The diagram is based on the dimensioned outdoor temperature in the area and the dimensioned supply temperature of the heating system. When these two values meet, the heating control’s curve slope can be read. This is set under menu 2.1, Curve coefficient.

FIGHTER 1240

To be able to produce heat when the collector circuit is disconnected, or during servicing, the heat pump can be set to standby mode, in which case heating is pro-duced only by the immersion heater. Hot water is not produced in standby mode. The compressor and col-lector system are then shutoff and only the heat medi-um pump and the immersion heater are active. The temperature is controlled by the thermostat (3). To select standby mode, set the switch (8) to “ ”.

Electrical step 2 is connected in standby mode.

Standby mode

When there is a demand for hot water, the heat pump gives this priority and devotes its entire output to water heating. No room heat is produced in this mode. Maxi-mum time for hot water charging is adjustable using menu 1.3. Heating is then produced for the remainder of the time, which is adjustable from menu 1.2, before any further hot water charging can take place.

If the electrical module is connected for heat produc-tion before hot water charging, one electrical stage remains operative during hot water operation. Hot water charging starts when the hot water sensor has fallen to the set start temperature (25 — 55 °C), adjustable on menu 1.4. Hot water charging stops when the water temperature on the hot water sensor (88) has reached (30 — 60 °C), adjustable on menu 1.5. Charging is also possible when the heat pump has reached its stop level for heating mode at the same time as less than 2 °C remains to the hot water start. The purpose of this is to minimise the number of starts.

For occasional higher demand for hot water, the Extra hot water function can be used to raise the tempera-ture to about 70 °C for 3 – 24 hours (press the Extra hot water button once). When the electrical module is connected for extra hot water the compressor stops. The value when the compressor stops and the immer-sion heater kicks in is adjustable between 50 – 60 °C in menu 1.7.

The supply of heat to the house is regulated in accord-ance with the chosen setting of the regulating curve (curve slope and offset). After adjustment, the correct amount of heat for the outside temperature is supplied. The heat pump’s flow temperature (menu 2.0) will hov-er around the theoretical required value (the value in brackets on the display). For subnormal temperatures the control system calculates a heating deficit in the form of degree-minutes, which means that heating production is accelerated. The larger the subnormal temperature, the greater the heat production.

There are four stages to heat production, one for the heat pump and three for the electrical module.

Safety valves■ The safety valves for the heating system and hot

water heater may release a small amount of water in the event of temperature changes.

■ The overflow water pipes from the safety valves must be uninhibited and be visible.

■ The safety valves must be inspected regularly to prevent clogging. This is normally done by tur-ning the safety valve knob anti-clockwise. The water should then flow through the safety valve. The safety valve must be replaced if this does not happen.

The appearance and location of the safety valves dif-fer between different installations. Contact your instal-ler for information.

Maintenance

General information for the installer

FIGHTER 1240

10

Current regulations require the heating installation to be inspected before it is commissioned. The inspec-tion must be carried out by a suitably qualified person and should be documented. The above applies to closed heating systems. If the heat pump is replaced, the installation must be inspected again.

FIGHTER 1240 is placed on a firm base, preferably a concrete floor or foundation. Install FIGHTER 1240 with its back to an outside wall, ideally in a room where noise does not matter. If this is not possible, avoid plac-ing it against a wall behind a bedroom or other room where noise may be a problem. Any wall that backs on to a bedroom should be fitted with sound insulation. Route pipes so they are not fixed to an internal wall that backs on to a bedroom or living room.

Installation

Guideline values for collectors

Inspection of the installation

For use with 40 x 2.4 PN 6.3 PEM hose.

The length of the collector hose varies depending on the rock /soil conditions and on the heating sys-tem, i.e. radiators or floor heating.Max length per collector should not exceed 400 m.

Where there is more than one collector, they must be connected in parallel, with a means of adjusting the flow.

For surface soil heat, the hose should be buried at a depth of about 1 metre and the distance between the hoses should be at least 1 metres.

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

FIGHTER 1240 can be used with only additional heat (electric boiler) to produce heating and hot water, for example, before the collector installation is complete. See menu 9.2.4. NOTE! Select Off to deactivate only additional heat and select the required oper-ating mode using the operating mode button.

The brine pump normally follows the operation of the heat pump. There is a special operating mode for con-tinuous operation for 10 days, followed by return to normal mode (this may be used before stable circula-tion has been established). See Settings, menu. 9.2.12.

FIGHTER 1240 is equipped with an electric anode to protect the enamelled hot water heater. The electric anode works automatically when FIGHTER 1240 is switched on and is positioned behind the lower, serv-ice cover.

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

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

■ When the LED flashes red, contact the installer.

Electric anode (enamel)

The FIGHTER 1240 must be transported and stored upright and dry. The FIGHTER 1240 may however be carefully laid on its back when being moved into a building.

Factors to be taken into account when designing the collector layout are geographical position, type of rock/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. If this is not possible, install high points to vent the air.

All collector pipes in heated rooms must be insulated against condensation. The level vessel (NK) must be installed as the highest point in the collector system and on the incoming pipe before the brine pump. Note that condensation may drip from the level vessel. Posi-tion the vessel so that this does not harm other equip-ment.

As the temperature of the collector system can fall below 0 °C it must be protected against freezing down to -15 °C. One litre of ready mixed brine per meter of collector hose (applies when using PEM-hose 40 x 2.4 PN 6.3) is used as a guide value when making the volume calculation.

Details of the antifreeze used must be shown on the level vessel.

Pipe installation must be carried out in accordance with current norms and directives. The heat pump can operate up to a return temperature of about 58* °C and an outgoing temperature of about 70* °C from the heat pump. The compressor produces up to 65* °C, the rest is obtained using additional heating.

* Applies to 5 kW 1-phase, 6–12 kW 3-phase 3 x 400 V.

The other heat pumps has a max return temperature of approximately 50 °C and an outgoing max tempera-ture from the heat pump of approximately 60 °C.

Since the FIGHTER 1240 is not fitted with shut-off valves, these must be fitted outside of the heat pump to make future servicing easier.

During assembly of FLM the pipes for the heat medi-um and water heater and possibly hot water circulation are routed backwards. The distance between FIGHT-ER 1240 and the wall ought to be 50 mm.

General

NOTE!The pipe system needs to be flushed

out before the heat pump is connected so that debris cannot damage

component parts.

Shut-off valves should be installed as close to the heat pump as possible. Fit the supplied particle filter on the incoming pipe.

In the case of connection to an open groundwater sys-tem, an intermediate frost-protected circuit must be provided, because of the risk of dirt and freezing in the evaporator. This requires an additional heat exchang-er.

Centralised load control/TariffIn those cases centralised load control or tariff control is used this can be connected to the terminal block X1 on the load monitor card (2), which is positioned behind the upper service cover.

Tariff A, the immersion heater is disconnected. Connect a potential free contact function to terminals X1:5 and X1:7.

Tariff B, the compressor is disconnected. Connect a potential free contact function to terminals X1:6 and X1:7.

Tariff A and Tariff B can be combined.

A made contact results in the electrical output being disconnected.

Load monitorNOTE! No function in a 1-phase installation.When many power consumers are connected in the property at the same time as the electric element is operating, there is a risk of the property's main fuse tripping. The heat pump is equipped with an integrated load monitor that controls the electrical steps on the electric element.

When the phase current is so high that there is a risk of the main fuses tripping, the load monitor reduces the electric element output until the risk of the main fuses tripping has passed. When the general power consumption drops, the electric element will be con-nected again.

A current transformer should be installed on each incoming phase conductor in to the distribution box to measure the current. The distribution box is an appro-priate installation point.

Connect the current transformers to a multi-core cable in an enclosure next to the distribution box. Use unscreened multi-core cable of at least 0.50 mm2, from the enclosure to the heat pump.

The cable is connected in the heat pump to the EBV-card on terminals X1:8 - X1:11. X1:11 is the common terminal block for the three current transformers.

The size of the property's main fuse is set using the knob (100) on the EBV-card. The setting can be checked in the menu 8.3.4.

RG 10, sensor for changing the room temperatureAn external sensor can be connected to FIGHTER 1240 to change the flow temperature and with that set the room temperature, for example, a room sensor (RG 10, accessory). The sensor is connected on terminals X1:3, X1:4 and X1:14 on the load monitor card (2).

Activated in menu 9.2.18The difference between the room temperature and the set room temperature affects the flow temperature. The required room temperature is set using the knob on RG 10 and is shown in menu 6.0.

Contact for changing the room temperature An external contact function can be connected to FIGHTER 1240 to change the flow temperature and in doing so change the room temperature, for example, a room thermostat (accessory) or a timer. The contactor should be potential free and momentary and is con-nected to terminals X1:3 and X1:4 on the load monitor card (2).When the contact is made, the heating curve offset is changed by the number of steps shown here. The val-ue is adjustable between -10 and +10. The value for the change is set on menu 2.5, External adjustment.

Contact for activation of Extra hot waterAn external contact function can be connected to FIGHT-ER 1240 for activation of the Temporary extra hot water function. The contactor should be potential free and momentary and is connected to terminals X4:3 and X4:4 on the load monitor card (2).When the contact makes for at least one second, the Temporary Extra hot water function is activated. An auto-matic return to the previously set function occurs after 24 hours.

Air is initially released from the hot water and venting may be necessary. If bubbling sounds can be heard from the heat pump, the entire system requires further venting. When the system has stabilised (correct pres-sure and all the air removed) the heating controls can be set at the required values.

Check the fluid level in the level vessel (85). If the level has dropped, close the valve under the vessel. You can then fill through the connection at the top of the vessel. After filling, open the valve again. To raise the pressure, close the valve on the incoming main pipe when the brine pump (KBP) is running and the level vessel (NK) is open, so that water is drawn in from the vessel.

The siphon principle is used to empty the water heater. This can be done either via the drain valve on the incoming cold water pipe or by inserting a hose into the cold water connection.

The compressor in FIGHTER 1240-12 is of the scroll type. It can only operate in one direction of rotation. Operating in the wrong direction can damage the compressor.To check that the direction of rotation is correct, carry out the following:■ Set the switch to 1.■ Check the hot gas temperature in menu 5.11. The

temperature should increase by 15 °C within 30 seconds from compressor start.

■ If the temperature, on the other hand, remains the same, the direction of rotation is incorrect. The noi-se produced is also different when rotating in the incorrect direction.

– Set the switch to 0 and cut the main power supply.

– Swap the two incoming phases on the terminal block for incoming electricity, -X9.

– Set the switch to 1 and repeat the rotation check.

Close the shut-off valves in heating medium system. Now open the drain valve (76). A small amount of water runs out, however, to fully empty the heating medium side requires the connector that joins the heating medium side and the connection on the heat pump VB-flow to be loosened a little to allow air to enter so the remaining water can run out. When the heating medium is empty the requisite service can be carried out.

When replacing the brine pump or drive side or when cleaning the pump, the shut-off valves in the collector system should be closed. The hose between the top of the evaporator and the brine pump is loosened on the evaporator. The loose hose end can now be bent down and emptied in a small bowl. Now loosen the connec-tion to KB-f a little to allow air to enter so the heat pump’s collector side is emptied completely. When the circuit is empty the requisite service can be carried out.
