F2040 – An excellent choice
F2040 is an air/water heat pump, specially designed for the Nordic climate,
which uses the outdoor air as its energy source.
The heat pump is intended for connection to water borne heating systems
and 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 below the stop temperature
all heating must then occur with external additional heat.
Excellent properties for F2040:
■Efficient twin rotary compressor
Efficient twin rotary compressor that operates at temperatures down
to -20 °C.
■Intelligent control

9F2040Chapter 2 | The heat pump – the heart of the house

An air/water heat pump can use the outdoor air to heat a property. The
conversion of the outdoor air's energy to property heating occurs in three
different circuits. In the brine circuit, (1) , free heat energy is retrieved from
the surroundings and transported to the heat pump. In the refrigerant
circuit, (2) , the heat pump increases the retrieved heat's low temperature
to a high temperature. In the heating medium circuit, (3) , the heat is dis-
tributed around the house.
Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s evaporator. Here, the air
releases the heating energy to the refrigerant and the air's temperature
drops. The cold air is then blown out of the heat pump.
B
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a refrigerant, which
also passes the evaporator. The refrigerant has a very low boiling point. In
the evaporator the refrigerant receives the heat energy from the outdoor
air and starts to boil.
C
The gas that is produced during boiling is routed into an electrically
powered compressor. When the gas is compressed, the pressure increases
and the gas’s temperature increases considerably, from approx. 5 °C to
approx. 80 °C.
D
From the compressor, gas is forced into a heat exchanger, condenser,
where it releases heat energy to the heating system in the house,
whereupon the gas is cooled and condenses to a liquid form again.
E
As the pressure is still high, the refrigerant can pass an expansion valve,
where the pressure drops so that the refrigerant returns to its original
temperature. The refrigerant has now completed a full cycle. It is routed
to the evaporator again and the process is repeated.
F
Heat medium circuit
The heat energy that the refrigerant produces in the condenser is retrieved
by the climate system's water, heating medium, which is heated to 55 °C
(supply temperature).
G
The heating medium circulates in a closed system and transports the heated
water's heating energy to the house water heater and radiators/heating
coils.
H
The temperatures are only examples and may vary between different installations and
time of year.

Contact with F2040
F2040 is controlled in various ways depending on your system. Your contact
with the heat pump takes place via your indoor module (VVM) or control
module (SMO). See relevant manual for more information.
During installation, the installation engineer adjusts the necessary settings
for the heat pump in the indoor module or control module, so that the
heat pump works optimally in your system.
11F2040Chapter 2 | The heat pump – the heart of the house

Maintenance of F2040
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient maintenance can cause serious damage to F2040, which is
not covered by the guarantee.
Checking grilles and bottom panel
Check that the inlet grille is not clogged by leaves, snow or anything else
regularly throughout the year.
You should be vigilant during windy conditions and/or in the event of
snow as the grilles can become blocked.
Also check that the drain holes in the bottom panel (three) are free from
dirt and leaves.
Regularly check that condensation is routed away correctly through the
condensation pipe. Ask your installer for assistance if required.

Keep free of snow and/or ice.
Cleaning the outer casing
If necessary the outer casing can be cleaned using a damp cloth.
Care must be exercised so that the heat pump is not scratched when
cleaning. Avoid spraying water into the grilles or the sides so that water
penetrates into F2040. Prevent F2040 coming into contact with alkaline
cleaning agents.
In event of long power cuts
In the event of prolonged power failures it is recommended that the part
of the heating system located outdoors is drained. Your installer has in-
stalled a shut off and drain valve to facilitate this. Call and ask your installer
if you are unsure.
Silent mode
The heat pump can be set to "silent mode", which reduces the heat pump's
noise level. The function is useful when F2040 must be placed in noise
sensitive areas. The function should only be used for limited periods as
F2040 may not reach its dimensioned output.
Saving tips
Your heat pump installation produces heat and cooling and/or hot water.
This occurs via the control settings you made.
Factors that affect the energy consumption are, for example, indoor tem-
perature, hot water consumption, the insulation level of the house and
whether the house has many large window surfaces. The position of the
house, e.g. wind exposure is also an affecting factor.
Also remember:
13F2040Chapter 2 | The heat pump – the heart of the house

■Open the thermostat valves completely (except in the rooms that are to
be kept cooler for various reasons, e.g. bedrooms). The thermostats slow
the flow in the heating system, which the heat pump wants to com-
pensate with increased temperatures. It then works harder and consumes
more electrical energy.
■Reduce or adjust the settings for heating in any external control systems.

Energy meter
Check the accommodation's energy meter regularly, preferably once a
month. This will indicate any changes in power consumption.
Newly built houses usually have twin energy meters, use the difference to
calculate your domestic electricity.
15F2040Chapter 2 | The heat pump – the heart of the house

New builds
Newly built houses undergo a drying out process for a year. The house
can then consume significantly more energy than it would thereafter.
After 1-2 years the heating curve should be adjusted again, as well as the
offset heating curve and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

5 Glossary
Additional heat
The additional heat is the heat produced in addition to the heat supplied
by the compressor in your heat pump. Additional heaters can be for ex-
ample, immersion heater, electric heater, solar power system,
gas/oil/pellet/wood burner or district heating.
Ambient temperature sensor
A sensor that is located outdoors on or close to the heat pump. This sensor
tells the heat pump how hot it is where the sensor is located.
Balance temperature
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 requirement
down to this temperature.
Charge coil
A charge coil heats the domestic hot water (tap water) in the water heater
with heating water (heating medium) from F2040.
Charge pump
See "Circulation pump".
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
Climate systems can also be called heating systems. The building is heated
using radiators, under floor coils or convector fans.
Coil tank
A heater with a coil in it. The water in the coil heats the water in the
heater.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
19F2040Chapter 5 | Glossary

Condenser
Heat exchanger where the hot gas state refrigerant condenses (cooled
and becomes a liquid) and releases heat energy to the house heating and
hot water systems.
COP
If a heat pump has COP of 5, this means that you only pay for a fifth of
your heating demand. This is the efficiency of the heat pump. This is
measured at different measurement values, e.g.: 7 / 45 where 7 stands
for the outdoor temperature and where 45 stands for how many degrees
the supply temperature is maintaining.
Disturbances in comfort
Disturbances in comfort are undesirable changes to the hot water/indoor
comfort, for example when the temperature of the hot water is too low
or if the indoor temperature is not at the desired level.
A malfunction in the heat pump can sometimes be noticed in the form of
a disturbance in comfort.
In most cases, the heat pump notes malfunctions and indicates this with
alarms in the display.
Domestic hot water
The water one showers in for example.
Double-jacketed tank
A heater with domestic hot water (tap water) is surrounded by an outer
vessel with boiler water (to the house radiators/elements). The heat pump
heats the boiler water, which in addition to going out to the all the house
radiators/elements, heats the domestic hot water in the inner vessel.
Efficiency
A measurement of how effective the heat pump is. The higher the value
is the better it is.
Electrical addition
This is electricity that, for example, an immersion heater uses as addition
during the coldest days of the year to cover the heating demand that the
heat pump cannot manage.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
