F730 – An excellent choice
F730 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 safeand 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 underfloor heating. It is
also prepared for connection to several different accessories, for example
climate systems with different temperatures.
F730 is equipped with acontrol 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 F730:
■Inverter controlled compressor
The heat pump has an inverter controlled compressor that automatically
adapts itself optimally and economically to your house and supplies your
installation with renewable energy.
■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 makes use of the heat in the building's ventila-
tion air to heat up the accommodation. The conversion of the ventilation
air's energy to accommodation heating is done in three different circuits.
From the outgoing ventilation air (1), free heating energy is retrieved from
the accommodation and transported to the heat pump. The heat pump
increases the retrieved heat's low temperature to a high temperature in
the refrigerant circuit, (2). The heat is distributed around the building 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.
A
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.
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 compressed, the pressure increases
and the gas's temperature increases considerably, from -5°C to approx.
100 °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 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 55 °C
(supply temperature).
G
The heating medium circulates in aclosed system and transports the heated
water's heat energy to the heat pump's integrated hot water heater and
the radiators/heating coils of the house.
H
The temperatures are only examples and may vary between different installations and
time of year.
