F470 – An excellent choice
F470 is part of a new generation of heat pumps, which have been intro-
duced 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.
Excellent properties for F470:
႑Integrated water heater
There is a water heater integrated in the heat pump, which is insulated
with environmentally friendly cellular plastic for minimal heat loss.
႑Scheduling 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).
႑Display with user instructions
The heat pump has a large display with easy-to-understand menus that
facilitate setting a comfortable climate.
႑Simple troubleshooting
In the event of a fault, the heat pump display shows what happened
and the actions to be taken.

NIBE™ F470Chapter 2 | The heat pump – the heart of the house8

Heat pump function
A 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 dis-
tributed 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 radiat-
ors/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.
I
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
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
55.
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 60.

heat pump. In this mode, the compressor and fans switch off and
the immersion heater engages. The heat pump display is not illumin-
ated and the status lamp illuminates yellow.
The automatic heating control system is not operational, so manual
shunt operation is required (see page 24).
