To be filled in when the heat pump has been

installed.

FIGHTER 2010 is an outdoor air heat pump, specially

designed for the Nordic climate. FIGHTER 2010 utilis-

es the outside air so there is no need for bore holes or

collectors in the ground. FIGHTER 2010 has an auto-

matic 2-step capacity regulator for the fan and com-

pressor.

The unique two-step control provides a very high ener-

gy coverage and great savings.

FIGHTER 2010 is designed for water based heating

systems and can be used together with most electric

boilers, oil-fired boilers or equivalent. The heat pump

includes an advanced control system for optimal con-

trol. FIGHTER 2010 is started by a start signal from

another controller or thermostat.

FIGHTER 2010 can also be controlled by a specially

designed controller, SMO 10*. This connects addition-

al heat and controls switching between room heating

and hot water heating.

In addition, FIGHTER 2010 can be docked to a

specially adapted hot water module, VVM 240*. This

contains a similar controller as SMO 10 and consists

of a water heater and additional heat in the form of an

electric boiler. FIGHTER 2010 and VVM 240 together

make up a complete heating plant.

With help of its unique 2-stage compressor, FIGHTER

2010 can heat hot water effectively at high outdoor

temperatures and provide a high output to the heating

system at low outdoor temperatures. This results in

much higher annual heat factors/savings for the heat

pump plant compared to traditional compressor tech-

nology.

If the outdoor temperature drops to a level under the

stop temperature all heating must then occur with

external additional heat.

FIGHTER 2010 is manufactured in two sizes 6 and 8.

Materials have been chosen to provide a long life and

to fully withstand the outdoor conditions that prevail in

the Nordic countries.

Maintenance routines

For Home Owners

FIGHTER 2010

FIGHTER 2010 is equipped with control and monitor-

ing equipment, however some exterior maintenance is

still necessary.

Make regular checks throughout the year that the inlet

grille is not clogged by leaves, snow or anything else.

In addition, you should ensure during the colder parts

of the year that too much frost or ice does not form

under FIGHTER 2010. Strong wind in connection with

extensive snowfall can cause the inlet and exhaust air

grilles to become clogged. Make sure that there is no

snow on the grilles.

If necessary the outer casing can be cleaned using a

damp cloth. Care must be exercised so that the plastic

cover is not scratched when cleaning. Avoid spraying

water into the grilles or on the sides so that water can

penetrate into FIGHTER 2010.

General information for the installer 5

FIGHTER 2010

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 2010 is placed outdoors on a firm base,

preferably a concrete foundation. FIGHTER 2010

should not be positioned next to sensitive walls, for

example, next to a bedroom. Also ensure that the

placement does not inconvenience the neighbours.

Large amounts of condensation water as well as melt

water from defrosting can be produced. Provide good

drainage at the installation area and make sure water

cannot run out onto paths or the like during periods

when ice can form. Ideally condensation water is led

off to a street inlet or the like.

The distance between FIGHTER 2010 and the house

wall should be at least 350 mm. Clearance in front of

FIGHTER 2010 should be at least one metre.

FIGHTER 2010 should not be placed so that recircula-

tion of outdoor air can occur, since this causes lower

output and efficiency.

FIGHTER 2010 should be transported and stored ver-

tically.

Transport and storage

Installation

Inspection of the installation

FIGHTER 2010 is equipped with an internal electronic

controller that handles all functions necessary for heat

pump operations.

Accordingly, defrosting, stop at max/min temperature,

connection of the compressor heater as well as

enabling the heater for the drip pan, monitoring of

motor protection and pressure switches are controlled.

In addition, the number of starts for respective capaci-

ties and the running time for respective capacities can

be read off.

The integrated controller is set during installation and

can be used during a service.

Under normal operation conditions the home owner

does not need to have access to the controller.

FIGHTER 2010 has an integrated electronic return

sensor that limits the return temperature. The flow and

return sensors are fitted during installation.

FIGHTER 2010 can also be switched on/off via sig-

nals from other control equipment or a thermostat. If

FIGHTER 2010 is to be controlled using the acces-

sories SMO 10 or VVM 240 then relevant procedures

are described in respective instructions.

SMO 10 and VVM 240 communicate with FIGHTER

2010, which means that the settings and measure-

ment values from FIGHTER 2010 can be adjusted

and read on SMO 10 and VVM 240.

FIGHTER 2010

For the Installer

Pipe installation must be carried out in accordance

with current norms and directives. FIGHTER 2005

works up to an outgoing temperature from the heat

pump of approximately 55 °C. See section “Commis-

sioning and adjusting” – “Adjustment, charge flow” for

the right flow setting. Since FIGHTER 2010 is not

equipped with shutoff valves on the water side these

must be fitted to facilitate future service. The return

temperature is limited by the return sensor and is

adjustable on channel 30.

General

FIGHTER 2010 is supplied with flow and return sen-

sors, sensors and cables are packed in the distribution

box. The edge board connector is fitted at the factory.

■

Flow sensor (89), yellow cable.

■

Return sensor (93), blue cable.

■

The flow and return sensors are routed through the

cable gland (102) to the measurement points.

■

The flow and return sensors are fitted on the

straight section of the copper pipe using cable ties

together with heating pipe paste and aluminium

tape.

NOTE! It is important that the contact between the

sensor and measurement point is good and that

the sensors are insulated.

Sensor placement

FIGHTER 2010 can be connected to the heating sys-

tem see the section “Docking” or according to one of

the system solutions that can be downloaded from the

website www.nibe.se/vvs .

The heat pump must be vented by the upper connec-

tion (70, WW-out) using the venting nipple on the

enclosed flexible hose. The supplied particle filter is

installed before the inlet, that is to say, the lower con-

nection (71, WW-in) on FIGHTER 2010. All outdoor

pipes are to be thermally insulated with at least

19 mm thick pipe insulation.

The circulation pump should be operational, even

if FIGHTER 2010 is not running, to prevent dam-

age due to freezing. The circulation pump can also

be controlled directly from FIGHTER 2010, terminal

(11), which takes the outdoor temperature into consid-

eration. Alternatively, the heat pump is connected to

an intermediate circuit with a heat exchanger, pump

and water with anti-freeze. Shutoff and drain valves

are fitted so that FIGHTER 2010 can be emptied in

the event of prolonged power failures.

The supplied flexible hoses act as vibration dampers.

The flexible hoses are fitted so a slight bend is creat-

ed, thus acting as vibration damping.

For the Installer

You can use a basic contactor or a thermostat to

switch the compressor on and off for heating hot

water. This function is given priority ahead of the heat-

ing function, which means that irrespective of the sta-

tus of the heating thermostat the compressor will work

according to the settings for hot water production.

This contactor should be of the breaking type (NC)

when the set temperature is reached. The contactor

should be potential free.

Set the preferred outdoor air temperature level on

channel 15 for shifting between compressor stage 1

and compressor stage 2.

Compressor stage 1 is used at high outdoor air tem-

peratures. Compressor stage 2 is used at low outdoor

air temperatures.

Connection of the switch for the hot water function is

made as set out in the picture below.

Additional heating/downtime

FIGHTER 2010 is equipped with a potential free con-

tactor intended for additional heat: Max 250V, 2A.

The setting of the outdoor air temperature (balance

temperature) when the additional heating relay is acti-

vated is made on channel 17, see the section “Control

Channel description”.

External additional heat: connected via additional

heating relay terminal (14). Conditions for connecting

additional heat:

■The outdoor air temperature should be lower than

the set balance temperature (channel 17).

■The compressor should have been operational in

stage 2 during at least the period selected in chan-

nel 28. Defrosting is included in this time.

If the outdoor air temperature drops down to a level

under the set value, stop temperature (downtime), in

channel 18 compressor operations are blocked and all

heating must take place using the external additional

heat via the downtime relay terminal (16). This func-

tion is also activated when FIGHTER 2010 is deener-

gized.

up and inspection”

Fighter 2010 is equipped with a soft-starter relay (97)

that limits the inrush current on the compressor to max

24 A.

The compressor must not be forced to start with peri-

ods shorter than 1 start per 15 minutes.

The balance temperature is the outdoor temperature

when the heat pump’s stated output is equal to the

building’s output requirement. This means that the

heat pump covers the whole building’s output require-

ment down to this temperature. Setting of the balance

temperature, additional heating, is made on channel

17.

When using a standard radiator system and with hot

water heating the stop temperature should not fall

below -7 °C. The setting of the stop temperature,

downtime, is done on channel 18.

FIGHTER 2010 is equipped with a compressor heater

that heats the compressor before start-up and when

the compressor is cold. The compressor must have

been switched on for 6-8 hours before the FIRST

start, see the section “Start-up and inspection”

Commissioning and adjusting

FIGHTER 2010

For the Installer

■Modular cable (44) or thermostat/strap, terminal

(30) is disconnected.

■The working switch is turned on.

■Check that all incoming phases are energized.

■Check that the miniature circuit-breaker (2) is on.

■The compressor heater (25) must have been oper-

ational for at least 6 hours before the compressor

start can be initiated. This is done by switching on

the control voltage and disconnecting the modular

cable or thermostat/strap.

■The display on the control card (34) shows C0/CC

F0 H1/H3 depending on the outdoor temperature.

When the thermostat or the like calls for

heating/hot water and FIGHTER 2010 is blocked

from starting by e.g. time conditions, C_ will flash

until starting is permitted. This will also be shown

until the modular cable or thermostat/strap is

connected. During this period the compressor is

heated to increase the service life.

■After 6-8 hours the modular cable, external

thermostats or strap on the input for hot water

and/or input for single step or double step ther-

mostat are connected. See the section “Electri-

cal connections” (Thermostat hot water, Single

step thermostat heating, Double step thermostat

heating).

■Restart SMO 10 or VVM 240.

■FIGHTER 2010 now makes two starts of 5 sec-

onds at 1 minute intervals. This is done so that the

control system can measure the compressor cur-

rents.

This procedure means the heat pump corrects itself

for the incoming phase sequence.

After measuring the compressor currents, the com-

pressor starts after approximately 20 minutes.

■Adjust the charge flow according to the diagram,

see the section “Adjustment, charge flow”

■Fill in the commissioning report on page 2.

Start-up and inspection

NOTE!

The live external control must be

taken into consideration when

connecting.

Adjusting the temperature difference (∆T) between the

flow temperature and the return temperature.

This is easily done by using the temperatures mea-

sured in Channel 32 (flow temperature) less Channel

29 (return temperature). This temperature difference

(∆T) is adjusted with the help of the circulation pump

and control valve. Adjustment is performed with stable

operation about 5 minutes after start, or about 5 min-

utes after defrosting with a cold outdoor temperature.

The temperature difference shall be as in the diagram

below (+1- 2K).

Air is initially released from the hot water and venting

may be necessary. If bubbling sounds can be heard

from the heat pump, the circulation pump and radia-

tors, the entire system requires further venting. When

the system has stabilised (correct pressure and all the

air removed) the heating controls can be set at the

required value.
