F2040 - An excellent choice
F2040 is an air/water heat pump specially developed for the Nordic climate,
which utilises the outside air so there is no need for bore holes or coils in
the ground.
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:
႑Efficient twin rotary compressor
Efficient twin rotary compressor that operates at temperatures down
to -20 °C.
႑Intelligent control
F2040 connected to intelligent control for optimum control of the heat
pump.
႑Fan
F2040 has automatic capacity regulation of the fan.
႑Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
The material has been chosen for a long service life.
႑Many possibilities
F2040 can with a NIBE hot water module, be used together with most
electric boilers, oil boilers or similar.
႑Silent operation
F2040 has a silent operation function that allows scheduling when
F2040 must operate at an even quieter noise level.

NIBE™ F2040Chapter 2 | The heat pump – the heart of the house10

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 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.
11NIBE™ F2040Chapter 2 | The heat pump – the heart of the house

Contact with F2040
F2040 has an integrated control system that controls and monitors the
heat pump operation. At installation the installation engineer makes the
necessary settings of the control system on the indoor module, so that the
heat pump works optimally in your system.
The heat pump is controlled in different ways depending on your system.
If you have an indoor module, e.g. VVM 310 or VVM 320, you can control
heat pump operation from it. See relevant manual for more information.
NIBE™ F2040Chapter 2 | The heat pump – the heart of the house12

Maintenance of F2040
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient oversight 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.
LEK
Prevent snow building up and covering the grille on F2040.
13NIBE™ F2040Chapter 2 | The heat pump – the heart of the house

LEK
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.
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:
႑Open 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
compensate with increased temperatures. It then works harder and
consumes more electrical energy.
NIBE™ F2040Chapter 2 | The heat pump – the heart of the house14

႑Reduce or adjust the settings for heating in any external control systems.

Domestic electricity
In the past it has been calculated that an average Swedish household has
an approximate annual consumption of 5000 kWh domestic electri-
city/year. In today's society it is usually between 6000-12.000 kWh/year.

cleaner, engine block heater = 6240 kWh domestic electricity/year.
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.
NIBE™ F2040Chapter 2 | The heat pump – the heart of the house16

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
heating curve offset and the building's thermostat valves, because the
heating system, as a rule, requires a lower temperature once the drying
process is complete.

3Disturbances in comfort
Troubleshooting
NOTE
Work behind covers secured by screws may only be carried out by, or under
the supervision of, a qualified installation engineer.
NOTE
As F2040 can be connected to a large number of external units, these
should also be checked.
NOTE
If the operating disturbance cannot be rectified by means of this chapter,
an installation engineer should be called.
NOTE
In the event of action to rectify malfunctions that require work within
screwed hatches the incoming electricity must isolated at the safety switch.
The following tips can be used to rectify comfort disruption:
Basic actions
Start by checking the following possible fault sources:
႑That the heat pump is running or that the supply cable to F2040 is
connected.
႑Group and main fuses of the accommodation.
႑The property's earth circuit breaker.
Low hot water temperature or a lack of hot water
This part of the fault-tracing chapter only applies if the heat pump is docked
to the hot water heater.
႑Large hot water consumption.
႑Wait until the hot water has heated up.
