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.

5Chapter 1 | Important informationNIBE F370

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.

NIBE F370Chapter 1 | Important information6

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.

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.

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.

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.

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 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.

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).

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.

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.

Status lamp

The status lamp indicates the status of the heat pump.

It:

•lights green during normal operation.

•lights yellow in emergency mode.

•lights red in the event of a deployed alarm.

OK button

The OK button is used to:

•confirm selections of sub menus/options/set val-

ues/page in the start guide.

Back button

The back button is used to:

•go back to the previous menu.

•change a setting that has not been confirmed.

Control knob

The control knob can be turned to the right or left. You

can:

•scroll in menus and between options.

•increase and decrease the values.

•change page in multiple page instructions (for example

help text and service info).

Switch

The switch assumes three positions:

•On ()

•Standby ( )

•Emergency mode ( )

Emergency mode must only be used in the event of a

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).

USB port

The USB port is hidden beneath the plastic badge with

the product name on it.

The USB port is used to update the software.
