Do not start F470 if there is a risk that the water in the
system has frozen.
Water may drip from the safety valve. A factory-fitted
overflow pipe runs from the safety valve to an overflow
cup. The overflow pipe is visible, its mouth is open and
not located close to electrical components. The safety
valve must be actuated regularly to remove dirt and to
check that it is not blocked.
If the supply cable is damaged, only NIBE, its service
representative or similar authorised person may replace
it to prevent any danger and damage.

NIBE F470Chapter 1 | Important information6

F470 – An excellent choice
F470 is a heat pump, which has been developed to supply your home
with inexpensive and environmentally friendly heating in the most effi-
cient manner.
Heat production is reliable and economical, thanks to an 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 underfloor heating. It
is also prepared for connection to several different products and accessor-
ies, e.g. extra water heater and climate systems with different temper-
atures.
F470 is equipped with a control computer for good comfort, good eco-
nomy 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.
EXCELLENT PROPERTIES FOR F470:
•Integrated water heater
There is a water heater integrated in the heat pump, which is insulated
with environmentally friendly cellular plastic for minimal heat loss.
•Scheduling the indoor comfort and hot water
Heating and hot water as well as ventilation, can be scheduled for each
day of the week or for longer periods (vacation).
•Display with user instructions
The heat pump has a large display with easy-to-understand menus that
facilitate setting a comfortable climate.
•Simple troubleshooting
In the event of a fault, the heat pump display shows what happened
and the actions to be taken.

Heat pump function
An exhaust air heat pump utilises the heat in the building’s ventilation
air to heat up the dwelling. The ventilation air’s energy is converted to
residential heating in three different circuits. From the outgoing ventilation
air (1), heating energy is recovered from the dwelling and transported to
the heat pump. The heat pump increases the recovered heat’s low
temperature to a high temperature in the refrigerant circuit (2). The heat
is distributed around the house in the heating medium circuit (3).
Ventilation air
The hot air is transferred from the rooms to the heat pump via the house ventilation
system.
The fan then routes the air to the heat pump’s evaporator. Here, the air releases the
heating energy and the air's temperature drops significantly. The cold air is then blown
out of the house.
Refrigerant circuit
A liquid, a refrigerant, circulates in a closed system in the heat pump which also passes
the evaporator. The refrigerant has a very low boiling point. In the evaporator the refri-
gerant receives the heat energy from the ventilation air and starts to boil.
The gas that is produced during boiling is routed into an electrically powered com-
pressor. When the gas is compressed, the pressure increases and the gas’s temper-
ature increases considerably, from approx. 5°C to approx. 80°C.
From the compressor, the gas is forced into a heat exchanger, condenser, where it
releases heat energy to the heat pump’s heating section, whereupon the gas is cooled
and condenses to liquid form again.
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.
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 temperat-
ure).
The hot water circulates in a closed system and is pumped out to the radiators/heating
coils of the house.
The heat pump’s integrated water heater is in the heating section. The heating medium
heats the hot water.
9Chapter 2 | The heat pump – the heart of the houseNIBE F470

Pre-heated supply air
The hot water also circulates to the heat pump’s supply air coil. The supply air coil
heats up the air that is blown out into the rooms that have supply air inlets.

The temperatures are only examples and may vary between different installations and
time of year.

EXTERNAL INFORMATION
When the heat pump door is closed, information can be received via an
information window and a status lamp.
Information window
Status lamp
Information window
The information window shows part of the display that is on the display
unit (located behind the door to the heat pump). The information window
can display different type of information, e.g. temperatures, clock, etc.
You determine what is to be displayed in the information window. Your
own combination of information is entered using the display unit. This
information is specific to the information window and disappears when
the heat pump door is opened.
Instructions on how to set the information window can be found on page
62.
Status lamp
The status lamp indicates the status of the heat pump: continuous green
light during normal function, continuous yellow light during activated
emergency mode or continuous red light in the event of a deployed
alarm.
Alarm management is described on page 68.

communicate with F470. Here you:
• switch on, switch off or set the heat pump in emergency mode.
• sets the indoor climate and hot water as well as adjusts the heat pump
to your needs.
• receive information about settings, status and events.
• see different types of alarms and receive instructions about how they
are to be rectified.
Display
Instructions, settings and operational information are shown on
the display. You can easily navigate between the different menus
