To be filled in when the heat pump has been installed

FIGHTER 2005 is an outdoor air heat pump, specially
designed for the Nordic climate. FIGHTER 2005 utilis-
es the outside air so there is no need for bore holes or
coils in the ground. FIGHTER 2005 has an automatic
2-step capacity regulator for the fan.
FIGHTER 2005 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 2005 is started by a start signal from
another controller, return line sensor or thermostat.
FIGHTER 2005 can also be controlled by a specially
designed controller, SMO 10*. This connects and dis-
connects the additional heat and controls switching
between room heating and hot water heating.
FIGHTER 2005 can both heat hot water effectively at
high outdoor temperatures and give a high output to
the heating system at low outdoor temperatures.
If the outdoor temperature drops to a level under the
stop temperature all heating must then occur with
external additional heat.
FIGHTER 2005 is manufactured in sizes 8 and 11.
Materials have been chosen to provide a long service
life and to fully withstand harsh outdoor conditions.

Maintenance routines
FIGHTER 2005
For Home Owners
4
FIGHTER 2005 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 2005. 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 2005.

General information for the installer
FIGHTER 2005
For the Installer
6
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 2005 is placed outdoors on a firm base,
preferable a concrete foundation. FIGHTER 2005
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
that ice can form. Ideally condensation water is led off
to a street inlet or the like.
The distance between FIGHTER 2005 and the house
wall should be at least 350 mm. Free space in front of
and above FIGHTER 2005 should be at least one
metre. FIGHTER 2005 should not be placed so that
the recirculation of outdoor air can occur. This causes
lower output and impaired efficiency.
FIGHTER 2005 should be transported and stored ver-
tically.
Transport and storage
Installation
Inspection of the installation
FIGHTER 2005 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 ena-
bling the heater for the drip pan, monitoring of motor
protection and pressure switches are controlled.
The number of starts and the operating time can also
be read.
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 2005 has an integrated electronic return
line sensor that limits the return temperature. The flow
and return line sensors are fitted during installation.
FIGHTER 2005 can also be switched on/off via signals
from other control equipment or a thermostat. When
FIGHTER 2005 is to be controlled using the accessory
SMO 10, the relevant control procedures are described
in respective instructions.
SMO 10 communicates with FIGHTER 2005, which
means that the settings and measurement values from
FIGHTER 2005 can be adjusted and read on SMO
10.

Pipe connections 7
FIGHTER 2005
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 58 °C. See section “Commis-
sioning and adjusting” – “Adjustment, charge flow” for
the right flow setting. Since FIGHTER 2005 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 line sensor and is
adjusted on channel 30.
General
FIGHTER 2005 can be connected to the heating sys-
tem – see the section Docking.
The heat pump must be vented by the upper connec-
tion (70, HM-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, HM-in) on FIGHTER 2005. 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 2005 is not running, to prevent dam-
age due to freezing. The circulation pump can also
be controlled directly from FIGHTER 2005, 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 2005 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.
Pipe connections (heating
medium)
When docking with FIGHTER 2005, a total water vol-
ume, in the boiler and accumulator, of at least 20 litres
boiler water per kW output on the heat pump is recom-
mended.
Water volumes
NOTE!
The pipe work must be flushed before
the heat pump is connected, so that
any contaminants do not damage the
components parts.
FIGHTER 2005 is supplied with flow and return line
sensors, sensors and cables are packed in the
distribution box. The edge board connector is fitted at
the factory.
■Flow line sensor (89), yellow cable.
■Return line sensor (93), blue cable.
■Flow and return line sensors are routed through
the cable gland (102) to respective measurement
points.
■The flow and return line 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.

FIGHTER 2005 charges the hot water heater/accumu-
lator tank (VVB/ACK). When the wood-fired boiler is
used, the heat pump and immersion heater are dis-
connected with a rising temperature on the flow line
sensor (RG) and starts again when the temperature
starts to drop. Self-circulation through the heat pump
is prevented by the check valve (BV). The return line
sensor (RG) is placed in the submerged tube on the
accumulator tank.

The figure shows the heat pump in its 1 x 230 V design.
■A heat pump must not be connected without the
permission of the electricity supplier and must be
connected under the supervision of a qualified
electrician.
■If a miniature circuit breaker is used this should
have a motor characteristic “D” (compressor opera-
tion). For MCB size see Technical Specifications.
■The FIGHTER 2005 does not include an isolator
switch on the incoming electrical supply. The instal-
lation must be preceded by a circuit-breaker with
at least a 3 mm breaking gap.
■If an insulation test is to be carried out in the build-
ing, disconnect the heat pump.
■Connect the heat pump to the terminal block (9),
via a distribution board with fuses. The heat pump
is not reconnectable between 1-phase and 3-phase;
neither can it be reconnected between 3 x 230 V
and 3 x 400 V.
■The signal cable for the thermostats is connected
to terminal (30) on the relay card (29). Cable type:
unscreened LiYY, screened LiYCY. Cable area, at
least 0.22 with cable lengths less than 50 m.
Alternatively the relevant signal cable is connected
from terminal (44) on the control card (34) to SMO
10.
■The circulation pump for FIGHTER 2005 is con-
nected to a separate supply or on terminal block
(11). NOTE! There is a risk of freezing when the
circulation pump is connected to the terminal
block (11) and FIGHTER 2005 is deenergized.
■A common alarm can be connected to terminal
(11).

Common alarm
The figure shows the heat pump in its 1 x 230 V design.
An outdoor sensor (15) is positioned on the underside
of FIGHTER 2005. If the FIGHTER 2005 faces south
or to the west, where there is a risk of intensive heat-
ing by the sun the outdoor sensor should be positioned
on a north or north-west facing wall.
Outside sensor
When the circulation pump is connected to the termi-
nal block (11) the pump is controlled by FIGHT-
ER 2005. Pump activity depends on the status of
FIGHTER 2005, heating/hot water requirement and
outdoor temperature. Pump exercising is handled by
FIGHTER 2005.
NOTE! There is a risk of freezing when the circula-
tion pump is connected to the terminal block (11)
and FIGHTER 2005 is deenergized.

You can use a basic thermostat to switch the compres-
sor on and off. This thermostat should be of the break-
ing type (NC) when the set temperature has been
reached. The contactor should be potential free.
When an external thermostat is not used, terminal
block 30, pos 6 and 7 should be strapped.
If you choose to use a single step thermostat then
option “0” on channel 13, see section “Control Chan-
nel description”, should be selected.
You set the required outdoor air temperature level for
switching between low and high fan speeds on chan-
nel 14. At an outdoor air temperature below 13°C, the
fan is forced to high speed irrespective of the setting
on channel 14.
Connection of the single step thermostat is made as
set out in the picture below.

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 heating function,
which means that irrespective of the status of the heat-
ing 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.
Connection of the switch for the hot water function is
made as set out in the picture below.

For the Installer
FIGHTER 2005
FIGHTER 2005 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 relay is activated is
made on channel 17, see the section “Control Chan-
nel description”.
External additional heat: connected via the additional
relay terminal (14). Conditions for connecting addition-
al heat:
■The outdoor air temperature should be lower than
the set balance temperature (channel 17)
■The compressor should have been operational for at
least the period selected in channel 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 function
is also activated when FIGHTER 2005 is deenergized.
The connection to the additional relay is made as set
out in the picture below.

The heating medium system is filled with water to the
required pressure. Vent the system using the venting
nipple on the enclosed flexible hose and possibly the
circulation pump.
Before commissioning, check that the heating circuit is
filled and well vented. Check the pipe work for leaks.

Preparations
NOTE!
The compressor must not be forced to
start with periods shorter than 1 start
per 15 minutes.
NOTE!
The compressor heater must have
been connected for 6-8 hours before
the first start, see the section “Start-up
and inspection”.
FIGHTER 2005 is equipped with a soft-start relay (97)
that limits the inrush current for the compressor.
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 heat, 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.

Soft-start relay
■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 and thermostat/strap.
■ The display on the control card (34) shows C0/CC
F0 H1/H3 depending on the outdoor temperature.
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 sections, Electri-
cal connections - Hot water thermostat, Single step
thermostat heating.
■Restart SMO 10 if necessary.
■Once the connection is made, the compressor
starts after approx. 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.
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 values.

For the Installer
Adjusting the temperature difference (∆T) between the
flow temperature and the return temperature.
This is easily done by using the temperatures meas-
ured 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). At outdoor temperatures above 28 °C
the charge flow can be increased by 30 % to obtain a
position ∆T.
The diagrams shows the heat pump with a high fan
speed, at low fan speeds ∆T will be 0.5 to 1 degree
lower.

Heater
The compressor heater is always active when the
compressor is switched off.
The drip tray heater is connected when the outdoor
temperature drops below the set value and is discon-
nected when the stop temperature is reached.
Fan
The fan has two speeds, high and low. The fan is con-
trolled by the outdoor temperature. The lower speed is
used when the outdoor temperature is high to limit the
output. The fan does not run during defrosting.
Compressor
The compressor has a minimum
running time of 5 minutes before
compressor stop can be effected.
