F470 is part of a new generation of heat pumps, which have been introduced
to supply your home with inexpensive and environmentally friendly heating.
Heat production is safe and economical with integrated hot water heater,
immersion heater, circulation pump and control system.
The heat pump can be connected to an optional low temperature heat distribution system. e.g. radiators, convectors or under floor heating. It is also
prepared for connection to several different products and accessories, e.g.
extra water heater and climate systems with different temperatures.
F470 is equipped with a control computer for good comfort, good economy
and safe operation. Clear information about status, operation time and all
temperatures in the heat pump are shown on the large and easy to read
display. This means, for example, that external unit thermometers are not
necessary.

NIBE™ F470Chapter 2 | The heat pump – the heart of the house8
Heat pump function
An exhaust air heat pump uses the heat that is in the building's ventilation
air to heat up the accommodation. The conversion of the ventilation air's
energy to accommodation heating occurs in three different circuits. From the
outgoing ventilation air (1) , free heating energy is retrieved from the accommodation 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 distributed around
the house.
Ventilation air
The hot air is transferred from the rooms to the heat pump via the house ventilation system.
A
The fan then routes the air to the heat pump’s evaporator. Here, the air releases
the heating energy to the brine and the air's temperature drops significantly. The
cold air is then blown out of the house.
B
Refrigerant circuit
Another liquid 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 ventilation 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 heat pump boiler section, 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 35 °C (supply
temperature).
G
The hot water circulates in a closed system and is pumped out to the radiators/heating coils of the house and to the heat pump supply air coil. The supply air battery
heats up the air that is blown out into the room with the supply air device.
H
The heat pump's integrated hot water heater is in the boiler section. The hot
boiler water heats the hot water.

Your heat pump requires minimal maintenance after commissioning. However,
it is recommended that your installation is checked and serviced annually by
qualified personnel. This is to ensure the continued efficient operation of
your heat pump, and that the warranty remains valid during the warranty
period.
If something unusual occurs, messages about the malfunction appear in the
display in the form of different alarm texts. See alarm management on page
68.

Cleaning the ventilation devices
The building’s ventilation devices should be
cleaned regularly with, for example, a small brush
to maintain the correct ventilation.
The device settings must not be changed.
Also check the outdoor air's intake grilles on the
house facade and clean if necessary.
NOTE
If you take down more than one ventilation
device for cleaning, do not mix them up.
Cleaning the air filter
Clean F470's two air filters regularly, how often depends on the amount of
dust in the ventilation air.
When it is time to clean, an alarm indication occurs is displayed. Factory setting
for alarm indication is every three months.
1.
Set the switch to .
2.
Remove the upper front cover by pulling straight out.
3.
Pull out the filter cassette.
4.
Take out the filter and shake/vacuum off any dirt. Do not use water or
other liquids for cleaning.
5.
Check that the filter is not damaged.
6.
Carry out assembly in reverse order.
Even if the filter appears clean, dirt collects in it and this affects the efficiency
of the filter. Therefore, replace it after 2 years. New filters can be ordered via
the installer.

Check pressure
F470 has a pressure gauge which shows the heating system pressure. The
pressure should be between 0.5 and 1.5 bar, but varies during temperature
changes. If the pressure drops to 0 or rises to 2.5 frequently, contact your
installer for troubleshooting.
L

3UHVVXUH JDXJH
Safety valves
The water heater's safety valve sometimes releases a little water after hot
water usage. This is because the cold water, which enters the water heater
to replace the hot water, expands when heated causing the pressure to rise
and the safety valve to open. The climate system's safety valve must be
completely sealed and not release any water.
The function of the safety valves must be checked regularly. The valves are
accessed via the service hatch. Perform checks as follows:
1.
Open the valve by turning the knob anti-clockwise carefully.
2.
Check that water flows through the valve.
3.
Close the valve by releasing it. If it does not close automatically when
released, turn it anti-clockwise slightly.
4.
The climate system may need to be refilled after checking the safety valve,
see the section “Filling the climate system”.

If this pressurised water heater develops a fault, e.g. a flow of hot water
from the overflow pipe, turn the heat pump off and contact your installer.
NIBE™ F470Chapter 2 | The heat pump – the heart of the house22
Filling the climate system
If the pressure is too low, increase as follows:
1.
Connect enclosed flexible hose between connection (QM11) and connection (QM12). Open filling valves. The boiler section and the rest of the
climate system are filled with water.
2.
After a while the pressure rises on the pressure gauge. When it is approx.

Venting the climate system
In event of repeated filling of the climate system or if bubbling sounds are
heard from the heat pump the system may need venting. This is carried out
as follows:
1.
Turn off the power supply to the heat pump.
2.
Vent the heat pump via the vent valve and the rest of the climate system
via the relevant vent valves.
3.
Vent the supply air battery via its vent valve.
4.
Keep topping up and venting until all air has been removed and the
pressure is correct.
NOTE
The vent pipe from the container must be drained of water before air can
be released. This means that the system is not necessarily bled despite the
flow of water when the bleed valve is opened.
23NIBE™ F470Chapter 2 | The heat pump – the heart of the house
Saving tips
Your heat pump installation produces heat and hot water. This occurs via the
control settings you made.
Factors that affect the energy consumption are, for example, indoor temperature, 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.
Even the house ventilation affects the energy consumption. It is therefore
important to perform a ventilation adjustment shortly after installing the heat
pump. At ventilation adjustment, a ventilation technician sets the house
ventilation device and the fans in F470, according to the projected values of
the house. The ventilation technician also adjusts the supply air temperature
so that it is a few degrees below the desired room temperature.
TIP
Check the supply air temperature on a cold day. If the setting was made on
a hot day, the ventilation may require adjustment. If so, contact your installer.
Also remember:
႑
During the adjustment period (winter time) all thermostat valves should
be fully open. The heat pump's heating settings are then adjusted so that
the correct indoor temperature is obtained, in most rooms, regardless of
the outdoor temperature. In rooms where a lower temperature is required,
the thermostat valves are lowered to the desired level. After a few months,
the remaining thermostats can be lowered slightly to avoid an increase
of the room temperature due to solar radiation, stove heat etc. Further
reductions may be required later on.
႑
You can lower the temperature when away from the house by scheduling
"holiday setting" in menu 4.7. See page 62 for instructions.
႑
You can reduce the ventilation speed when you are away by scheduling
in menu 1.3.3. See page 34 for instructions.
႑
If you activate "Hot water Economy", less energy is used.

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

If the house has several climate systems, this is indicated on the display by a
thermometer for each system.
Set the temperature (with room sensors installed and activated):
Setting range: 5 - 30 °C
Default value: 20
The value in the display appears as a temperature in °C if the heating system
is controlled by a room sensor.
To change the room temperature, use the control knob to set the desired
temperature in the display. Confirm the new setting by pressing the OK button. The new temperature is shown on the right-hand side of the symbol in
the display.
Setting the temperature (without room sensors activated):
Setting range: -10 to +10
Default value: 0
The display shows the set values for heating (curve offset). To increase or reduce the indoor temperature, increase or reduce the value on the display.
Use the control knob to set a new value. Confirm the new setting by pressing
the OK button.

The number of steps the value has to be changed to achieve a degree change
of the indoor temperature depends on the heating unit. One step for under
floor heating whilst radiators may require three.
Setting the desired value. The new value is shown on the right-hand side of
the symbol in the display.
Caution
An increase in the room temperature can be slowed by the thermostats for
the radiators or under floor heating. Therefore, open the thermostat valves
fully, except in those rooms where a cooler temperature is required, e.g.
bedrooms.
TIP
Wait 24 hours before making a new setting, so that the room temperature
has time to stabilise.
If it is cold outdoors and the room temperature is too low, increase the curve
slope in menu 1.9.1 by one increment.
If it is cold outdoors and the room temperature is too high, lower the curve
slope menu 1.9.1 by one increment.
If it is warm outdoors and the room temperature is too low, increase the

Menu
1.9.1
In the menu heating curve the so-called heating curve for your house can
be viewed. The task of the heating curve is to give an even indoor temperature, regardless of the outdoor temperature, and thereby energy efficient
operation. It is from this heating curve that the heat pump’s control computer
determines the temperature of the water to the heating system, flow line
temperature, and therefore the indoor temperature. You can select heating
NIBE™ F470Chapter 3 | F470 – at your service36
curve and read off how the flow line temperature changes at different outdoor
temperatures here.
Curve coefficient
The slope of the heating curve indicates how many degrees the supply
temperature is to be increased/reduced when the outdoor temperature
drops/increases. A steeper slope
means a higher supply temperature
at a certain outdoor temperature.

The optimum slope depends on the climate conditions in your location, if the
house has radiators or under floor heating and how well insulated the house
is.
The heating curve is set when the heating installation is installed, but may
need adjusting later. Thereafter the heating curve should not need further
adjustment.
Caution
In the event of making fine adjustments for the indoor temperature, the heat
curve must be offset up or down instead, this is done in menu 1.1 temper-
ature .
Curve offset
An offset of the heating curve means
that the supply temperature changes
as much for all the outdoor temperatures, e.g. that a curve offset of +2
steps increases the supply temperature by 5 °C at all outdoor temperatures.

is a higher operating cost.
In this operating mode the compressor is not active and only additional
heating is used.
Functions
"compressor" is that which produces heating and hot water for the accommodation. If "compressor" is deselected, a symbol in the main menu on the
heat pump symbol is displayed. You cannot deselect "compressor" in
manual mode.
"addition" is what helps the compressor to heat the accommodation and/or
the hot water when it cannot manage the whole requirement alone.
"heating" means that you get heat in the accommodation. You can deselect
the function when you do not wish to have heating running.
Caution
If you deselect "addition" it may mean that insufficient hot water and/or
heating in the accommodation is achieved.

To reduce energy consumption during a holiday you can schedule a reduction
in heating, ventilation and hot water temperature.
If a room sensor is installed and activated the desired room temperature (°C)
is set during the time period. This setting applies to all climate systems with
room sensors.
If a room sensor is not activated, the desired offset of the heat curve is set.
This setting applies to all climate systems without room sensors. A one degree
change in room temperature requires one increment for under floor heating
and approximately two to three increments for the radiator system.
Vacation scheduling starts at 00:00 on the start date and stops at 23:59 on
the stop date.
TIP
Complete holiday setting about a day before your return so that room temperature and hot water have time to regain usual levels.
TIP
Set the vacation setting in advance and activate just before departure in order
to maintain the comfort.
NIBE™ F470Chapter 3 | F470 – at your service62
Caution
If you choose to switch off hot water production during the vacation “periodic increases" (preventing bacterial growth) are blocked during this time.
"periodic increases" started in conjunction with the vacation setting being
completed.
Caution
If the exhaust air temperature falls below 16 °C, the compressor is blocked
and the electrical addition is permitted to intervene. When the compressor
is blocked heat is not recovered from the exhaust air.

Disturbances in comfort
In most cases, the heat pump notes operational interference (operational interference can lead to disturbance in comfort) and indicates this with alarms
and shows action instructions in the display.
Info-menu
All the heat pump measurement values are gathered under menu 3.1 in the
heat pump menu system. Looking through the values in this menu can often
simplify finding the fault source. See page 54 for more information about
menu 3.1.

In the event of an alarm, some kind of malfunction has occurred, which is
indicated by the status lamp changing from green continuously to red continuously. In addition, an alarm bell appears in the information window.
Alarm
In the event of an alarm with a red status lamp a malfunction has occurred
that the heat pump cannot remedy itself. In the display, by turning the control
knob and pressing the OK button, you can see the type of alarm it is and reset
it. You can also choose to set the heat pump to aid mode.
info / action Here you can read what the alarm means and receive tips on
what you can do to correct the problem that caused the alarm.
NIBE™ F470Chapter 4 | Disturbances in comfort68
reset alarm In most cases it is enough to select "reset alarm" to correct the
problem that caused the alarm. If a green light illuminates after selecting
"reset alarm" the alarm has been remedied. If a red light is still visible and a
menu called ”alarm” is visible in the display, the problem that caused the
alarm remains. If the alarm disappears and then returns, contact your installer.
aid mode ”aid mode” is a type of emergency mode. This means that the
heat pump produces heat and/or hot water despite there being some kind
of problem. This can mean that the heat pump's compressor is not running.
In this case the immersion heater produces heat and/or hot water.
Selecting "aid mode” is not the same as correcting the problem that caused
the alarm. The status lamp will therefore continue to be red.
If the alarm does not reset, contact your installer for suitable remedial action.
NOTE
Always gives the heat pump's serial number when contacting your installer.

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 example,
immersion heater, electric heater, gas/oil/pellet/wood burner or district heating.
Calculated flow line temperature
The temperature that the heat pump calculates that the heating system requires for an optimum accommodation temperature. The colder the outdoor
temperature, the higher the calculated supply temperature.
Circulation pump
Pump that circulates liquid in a pipe system.
Climate system
The climate system can also be called the heating and/or cooling system. The
building is cooled or heated using radiators, under floor coils or convector
fans.
Compressor
Compresses the gas state refrigerant. When the refrigerant is compressed,
the pressure and the temperature increase.
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.
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 operational interference and indicates
this with alarms and shows instructions in the display.
NIBE™ F470Chapter 6 | Glossary74
Domestic hot water
The water one showers in for example.
Electrical addition
This is the electricity that, for example, an immersion heater produces when
the compressor's output is not sufficient to fulfil the property's heating demand.
Emergency mode
A mode that can be selected using the switch in the event of a fault, which
means that the compressor stops. When the heat pump is in emergency
mode, the building and/or hot water is heated using an immersion heater.
Evaporator
Heat exchanger where the refrigerant evaporates by retrieving heat energy
from the air which then cools.
Exhaust air
The air that comes from the exhaust air device in the various rooms of the
accommodation, to F470.
Exhaust air devices
Vents, usually in the ceiling, in the kitchen/bathroom/clothes closet where
the air is drawn in to be forwarded to F470.
Expansion valve
Valve that reduces the pressure of the refrigerant, whereupon the temperature
of the refrigerant drops.
Expansion vessel
Vessel with heating medium fluid with the task of equalising the pressure in
the heating medium system.
Extract air
The air that the heat pump has retrieved heat from and which has therefore
been cooled. This air is blown out of the building.
75NIBE™ F470Chapter 6 | Glossary
Flow pipe
The line in which the heated water is transported from the heat pump out
to the house heating system (radiators/heating coils).
Heat exchanger
Device that transfers heat energy from one medium to another without mixing
mediums.
Heat factor
Measurement of how much heat energy the heat pump gives off in relation
to the electric energy it needs to operate. Another term for this is COP.
Heating curve
The heating curve determines which heat the heat pump is to produce depending on the temperature outdoors. If a high value is selected, this tells
the heat pump that it must produce a lot of heat when it is cold outdoors in
order to achieve a warm indoor temperature.
Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water.
Heating medium side
Pipes to the house’s climate system make up the heating medium side.
Hot water heater
Container where domestic water is heated. Is located inside the heat pump,
but an extra hot water heater can be installed in the event of large hot water
requirements.
Outdoor air
Air that is drawn into the heat pump and heated.
Outside sensor
A sensor that is located outdoors. This sensor tells the heat pump how hot
it is outdoors.
NIBE™ F470Chapter 6 | Glossary76
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if nonpermitted pressures occur in the system. A high pressure pressostat trips if
the condensing pressure is too great. A low pressure pressostat trips if the
evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with F470.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and that,
through pressure changes, evaporates and condenses. During evaporation,
the refrigerant absorbs heating energy and during condensing, gives off
heating energy.
Return pipe
The line in which the water is transported back to the heat pump from the
house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Room sensor
A sensor that is located indoors. This sensor tells the heat pump how hot it
is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shunt
A valve that mixes the hot water with a small amount of slightly cooler water.
There is a shunt in the heat pump that mixes the supply water with the return
line water so that the heating system reaches the correct temperature.
Supply air
The heated air that is blown from the heat pump and out into the room.
77NIBE™ F470Chapter 6 | Glossary
Supply air device
Valves, usually in the ceiling, where the heated supply air is blown out and
aids in heating up the accommodation.
Supply temperature
The temperature of the heated water that the heat pump sends out to the
heating system. The colder the outdoor temperature, the higher the supply
line temperature becomes.
