NIBE™ F2120Chapter 1 | Important information8

F2120 – An excellent choice
F2120 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 F2120:
■Efficient speed-controlled scroll compressor
Efficient speed-controlled scroll compressor that operates at temperat-
ures down to -25 °C.
■Intelligent control
F2120 connected to intelligent control for optimum control of the heat
pump.
■Fan
F2120 has automatic capacity regulation of the fan.
■Long service life
The material has been chosen for a long service life and is designed to
withstand the Nordic outdoor conditions.
■Many possibilities
F2120 with an NIBE indoor module/NIBE control module, can be used
together with most electric boilers, oil boilers or similar.
■Silent operation
F2120 has a silent operation function that allows scheduling when F2120
must operate at an even quieter noise level.

NIBE™ F2120Chapter 2 | The heat pump – the heart of the house10

An air/water-heat pump can use the outdoor air to heat up a home. The
conversion of the outdoor air's energy to residential 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. The heat pump
increases the retrieved heat's low temperature to a high temperature in
the refrigerant circuit, (2). The heat is then distributed around the building
by the heating medium circuit (3).
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™ F2120Chapter 2 | The heat pump – the heart of the house

Contact with F2120
F2120 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 use it
to control heat pump operation. See relevant manual for more information.
NIBE™ F2120Chapter 2 | The heat pump – the heart of the house12

Maintenance of F2120
Regular checks
When your heat pump is located outdoors some external maintenance is
required.
NOTE
Insufficient oversight can cause serious damage to F2120 which is not
covered by the guarantee.
Checking grilles and bottom panel on F2120
Regularly check throughout the year that the grille is not clogged by leaves,
snow or anything else.
You should be vigilant during windy conditions and/or in the event of
snow as the grille can become blocked.
Regularly check that condensation is routed away correctly through the
condensation pipe. Ask your installer for assistance if required.

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 F2120. Prevent F2120 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 F2120 must be placed in noise
sensitive areas. The function should only be used for limited periods as
F2120 may not reach its dimensioned output.

More detailed information about updating software via USB can be found
in the installer manual for your indoor module or control module.
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:
■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.

Example: A family with 2 children live in a house with 1 flat-screen TV, 1
digital box, 1 DVD player, 1 TV games console, 2 computers, 3 stereos, 2
bulbs in the WC, 2 bulbs in the bathroom, 4 bulbs in the kitchen, 3 bulbs
outside, a washing machine, tumble drier, fridge, freezer, oven, vacuum
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.
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.

3 Disturbances 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 F2120 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:
■That the heat pump is running or that the supply cable to F2120 is con-
nected.
■Group and main fuses of the accommodation.
■The property's earth circuit breaker.
■F2120 automatic protection (FB1). (Only if KVR 10 is installed.)
