Do not start F370 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. An over-
flow pipe runs from the overflow cup to a
suitable drain. The mouth of the overflow
pipe must be open. 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 author-
ised person may replace it to prevent any
danger and damage.

F370 – An excellent choice
F370 is a heat pump that has been developed to supply your
house with ventilation, heating and hot water in a cost-ef-
fective and environmentally friendly manner.
Heat production is reliable and economical, thanks to an in-
tegrated hot water heater, immersion heater, circulation
pump and control system.
The heat pump can be connected to an optional low temper-
ature heat distribution system. e.g. radiators, convectors or
underfloor heating. It is also prepared for connection to
several different products and accessories, e.g. extra water
heater and climate systems with different temperatures.
F370 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 neces-
sary.
EXCELLENT PROPERTIES FOR F370:
•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-under-
stand 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 house’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 transferred 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).

The temperatures are only examples and may vary between
different installations and time of year.
Ventilation air
The hot air (exhaust 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 thermal energy and the air’s tem-
perature drops significantly. The cold air (extract air) is then
blown out of the house.
B
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 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 com-
pressed, the pressure increases and the gas’s temperature
increases considerably, from approx. 5°C to approx. 80°C.
D
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.
E
As the pressure is still high, the refrigerant can pass an ex-
pansion valve, where the pressure drops so that the refriger-
ant 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 condens-
er 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.
H
The heat pump’s integrated water heater is in the heating
section. The heating medium heats the hot water.

EXTERNAL INFORMATION
When the heat pump door is closed, information can be re-
ceived 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 in-
formation window and disappears when the heat pump door
is opened.
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 32.

F370 GUSB port
There is a display unit behind the heat pump door, which is
used to communicate with F370. 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 and options to set the comfort or
obtain the information you require.

The OK button is used to:
•confirm selections of sub menus/options/set val-
ues/page in the start guide.

fault on the heat pump. In this mode, the compressor
switches off and the immersion heater engages. The heat
pump display is not illuminated and the status lamp illu-
minates yellow.
The automatic heating control system is not operational,
so manual shunt operation is required (see page 14).
