The mode for setting the indoor temperature is accessed by pressing the OK

button twice, when in the start mode in the main menu. Read more about

the settings on page 31.

Increase hot water volume

To temporarily increase the amount of hot water, first turn the control knob

to mark menu 2 (water droplet) and then press the OK button twice. Read

more about the settings on page 45.

In event of disturbances in comfort

If a disturbance in comfort of any type occurs there are some measures that

Safety information

This appliance can be used by children aged from 8

years and above and persons with reduced physical,

sensory or mental capabilities or lack of experience and

knowledge if they have been given supervision or in-

struction concerning use of the appliance in a safe way

and understand the hazards involved. Children shall not

play with the appliance. Cleaning and user maintenance

shall not be made by children without supervision.

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. 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 F370Chapter 1 | Important information6

F370 – An excellent choice

F370 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.

F370 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 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-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.

2 The heat pump – the heart of

the house

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.

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

61.

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 67.
