The FIGHTER 1210 consists of a heat pump, water
heater, electrical element, circulation pumps, a soft-
start relay and control computer with display. FIGHT-
ER 1210 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
heater. 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.
During the hot season, solar radiation and heat given
off by people and equipment are sufficient to keep the
house warm. 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.
This adjustment takes place automatically, since the
FIGHTER 1210 is equipped with a control computer
for optimal, safe operation. However, the heat pump
must first be given the correct basic setting.
Control of the heat production is performed based on
the floating condensing principle, i.e. the temperature
level needed for heating at a specific outdoor temper-
ature is produced guided by collected values from the
outdoor and flow sensors. As an option, room sensors
can also be used to compensate for variations in room
temperature. Hot water production is given priority and
controlled by means of temperature sensors in the
water heater and an operating pressostat.
For general information and more reliable control of
the function there are also sensors for incoming and
outgoing brine temperatures (collector). If required, a
minimum limit can be set for the outgoing brine tem-
perature (for example, with a groundwater system).
General
Examples of basic data selection:
1. House with low temperature* radiator systems
Markaryd = Area 10 (5). Select curve 10 on the
display 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 timber
floor structure
Markaryd = Area 10 (5). Select curve 8 (10-2=8)
on the display and -1 on the Increase/reduce heat
knob.
*A low temperature radiator system refers to a sys-
tem where the flow temperature needs to be 55 °C
on the coldest day.
** Floor heating can be dimensioned very differently.
Examples 2 and 3 above refer to a system where
the flow temperature needs to be approximately
35 - 40 °C resp 45 - 50 °C on the coldest day.
The values stated on the map (see the next page)
apply for the Curve slope.
The first value applies for low temperature *radiator
systems. The Increase/reduce heat knob is set to -2.
The value in brackets refers to floor heating systems**
installed in concrete floor structures. When the system
is installed in a timber floor structure you can use the
number before the brackets, but this value must be
reduced by two units. In these cases Increase/reduce
heat is set to -1.
The map values are usually a good starting point and
concern an approximate room temperature of 20°C.
The values can be adjusted later if necessary.
Basic values for the automatic
heating control system
Setting takes place by programming the
Curve slope, see the section Available information
and settings on the display, and by setting the Heating
curve offset using the Increase/reduce heat knob on
the panel.
If you do not know the correct settings use the basic
data 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.
Readjusting the setting.
Cold weather conditions
If the room temperature is too low, increase the val-
ue for the heating curve by one step.
If the room temperature is too high, reduce the val-
ue for the heating curve by one step.
Warm weather conditions
If the room temperature is too low, turn the
Increase/reduce heat
knob one step clockwise.
If the room temperature is too high, turn the
Increase/reduce heat knob one step anticlockwise.
Changing the room temperature manually.
If you want to temporarily or permanently increase or
lower the indoor temperature in relation to the previ-
ous heat setting, turn the Increase/reduce heat
knob
clockwise or anticlockwise. One scale marking corre-
sponds to a change of about one degree in the room
temperature.
NOTE! An increase in the room temperature may be
inhibited by the radiator or floor heating thermostats, if
so these must be turned up.

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. When the demand for hot water is high, the
maximum time for water heating is approximately 45
minutes. After this, room heating is produced for 15
minutes before further water heating can take place.
If the electrical module is connected for heat produc-
tion before hot water charging, one stage remains
operative during hot water operation. Hot water
charging starts when the hot water sensor has fallen
to the set start temperature (30 –49 °C). In order to
reach the maximum hot water temperature, hot water
charging is stopped by the operating pressostat on
the heat pump. In addition, charging can take place
when the heat pump has reached its stop-level for
heating mode at the same time as less than 2 °C is
needed before the start of hot water. The purpose of
this is to 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 the
hot water. Usually the outgoing hot water is hotter
than the indicated temperature.
For occasional higher demand for hot water, the Extra
hot water function can be used to raise the tempera-
ture to about 60 °C for 24 hours (press the Extra HW
button once). The electrical module is used to raise
the temperature above 50 °C.
There is also a function for periodic raising of the hot
water temperature (press the Extra HW button twice).
In this mode, the temperature is raised temporarily by
means of the electrical module to about 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
(curveslope and offset). After adjustment, the correct
amount of heat for the outside temperature is sup-
plied. The heat pump’s flow temperature. (WW-out)
will hover around the theoretical required value (the
value in brackets on the display). For subnormal tem-
peratures the computer calculates a deficit in the form
of degree minutes, which results in the acceleration of
heat production. The larger the subnormal tempera-
ture, the greater the heat production.
There are four stages to heat production, one for the
heat pump and three for the electrical module. The
output of the electrical element as supplied is
6 kW (FIGHTER 1210 –4, 3 kW) but it can be rewired
to give 9 kW
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 heat 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 circuit and the immersion heater are active. The
temperature is controlled by the thermostat (3). To
select standby mode, set the switch (8) to .

FIGHTER 1210 is placed on a firm base, preferably a
concrete floor or foundation. Install FIGHTER 1210
with its back to an outside wall, ideally in a room
where noise does not matter. If this is not possible,
avoid placing it against a wall behind a bedroom or
other 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 internal
wall that backs on to a bedroom or living room.
The FIGHTER 1210 must be transported and stored
upright and dry. The FIGHTER 1210 may however be
carefully laid on its back when being moved into a
building.

For use with 40 x 2.4 PN 6.3 PEM hose.
For size 4, 32 x 2.0 PN 6.3 PEM hose.
The length of the collector hose varies depending
on the rock /ground conditions and on the heating
system, i.e. radiators or floor heating.
Max length per collector should not exceed 400m.
Where there is more than one collector, they must be
connected in parallel, with a means of adjusting the
flow.
The hose should be buried at a depth of about 1 metre
and the distance between the hoses should be at least
1 metre.
For several bore holes, the distance between the
holes must be at least 15m.
The unit can be used exclusively as an electric boiler,
to produce heat and hot water, for example before the
collector installation is complete. For this mode, the
hot water temperature is preset to 50 °C. See Set-
tings, menu 14.
The brine pump normally follows the operation of the
heat pump. There is a special operating mode for
continuous operation for 10 days, followed by return
to normal mode (this may be used before stable circu-
lation has been established). See Settings, menu 14.

For the Installer
Hold the Channel button down for about 7 seconds to
access the following menus.
Then press Channel again until you reach the desired
display mode. To change the value of a displayed vari-
able, first press the Increase button once. A cursor will
appear under the value. The value can now be
changed by pressing the Increase or Reduce buttons.
Pressing the Channel button again moves the cursor
to the value below, which in some cases can now be

Control of the electrical output for best comfort is man-
aged by the computer. It calculates the flow tempera-
ture deficit in the form of degree-minutes.
If, for example, the flow temperature has been 3
degrees lower than the calculated flow temperature for
60 minutes; 3 x 60 = 180 degree minutes is registered
by the computer. Using the standard setting the num-
ber of degree minutes should amount to 360 (60 +
300) before the immersion heater’s first step is con-
nected. After which the following steps are connected
with a further 100 degree minutes difference. The out-
put step remains actuated until the degree minute
deficit for each step has been compensated, which
means that the flow temperature must be as many
degree minutes above the calculated flow level as it
was previously under. This is how the
average flow temperature calculated by the computer
is obtained.

It is important with some concrete floors to maintain
the right floor temperature during an initial period. This
is so the floor dries correctly.
FIGHTER 1210 has a function for this drying process.
The process can be divided into two periods where
the number of days and temperature are set for
respective periods. This setting is made on the chan-
nel 18. When the FDP interval 1 is set to 0 days the
function is not active.
FDP int 1
Shows the number of days at step 1.
WW-out
Shows the flow temperature at step 1.
FDP int 2
Shows the number of days at step 2.
WW-out
Shows the flow temperature at step 2.
It is possible to set the number of days from 1 to 10
and the temperature from 15 to 50 °C. Once the dry-
ing process is finished the FIGHTER 1210 automati-
cally returns to normal control.
If a power failure occurs during the drying process the
current time and temperature are stored. When the
power returns the drying process continues with the
settings that applied before the power failure. Thus
the drying process is carried out to a 100%.
To return to display 9, press the Channel button. You
then return to the original display 1. Press the Channel
button and keep it held down for about 7 seconds to
return to service mode, display 9.

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.
Position the vessel so that this does not harm other
equipment.
As the temperature of 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 col-
lector 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.
The collector circuit may be connected from the left or
from the right. The lower side panels are swapped
over to suit the chosen connection option. The
enclosed connecting pipes for the brine, are secured
using the clips in the punched tabs that are folded
down on the side in question.
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
system, an intermediate frost-protected circuit must
be provided, because of the risk of dirt and freezing in
the evaporator. This requires an additional heat
exchanger.
Pipe installation must be carried out in accordance
with current norms and directives. The heat pump can
only operate up to a return temperature of about 50 °C
and an outgoing temperature of about 60 °C from the
heat pump. Since the FIGHTER 1210 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 30 the pipes for the heat
medium and water heater and possibly hot water cir-
culation are routed backwards. The distance between
FIGHTER 1210 and the wall ought to be 50 mm.
General
Pipe connections for the heat medium side are made
at the top. All required safety devices, shut-off valves
(as close to the heat pump as possible), and particle
filter (supplied) are fitted.
When connecting to a system with thermostats on all
radiators, a relief valve must be fitted, or some of the
thermostats must be removed to ensure sufficient
flow.
Pipe connections (heating

Pipe connections (collector)
The water heater must be fitted with the necessary
valve equipment.
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant
consumer of hot water is installed.

The installation can be supplemented with the exhaust
air module FLM 30 to provide ventilation recovery.
To avoid condensation, all pipes and other cold sur-
faces must be isolated with diffusion-proof material.
The heat pump should be supplemented with an elec-
tric water heater if a bubble pool or other significant

Tap water connection
The equipment can be supplemented with a fan coil
unit to make the connection of ambient cold possible.
To avoid condensation, all pipes and other cold sur-
faces must be isolated with diffusion-proof material.
Where the cooling demand is high, fan convectors
with drip trays and drain connection are needed.
