VVM 500 – An excellent choice
VVM 500 is an indoor module, which has been developed to
supply your home with inexpensive and environmentally
friendly heating and hot water in the most efficient manner.
The integrated hot water coil, immersion heater, circulation
pumps, solar coil and control system provide reliable and
economical heat production.
The indoor module can be connected to an optional low
temperature heat distribution system, e.g. radiators, con-
vectors or underfloor heating. It is also prepared for connec-
tion to a number of different products and accessories, e.g.
solar or other external heat source, extra water heater,
swimming pool and climate systems with different temper-
atures.
VVM 500 is equipped with a control computer for good
comfort, good economy and safe operation. Clear informa-
tion about status, operating time and all temperatures in
the system is shown on the large and easy to read display.
This means, for example, that external unit thermometers
are not necessary.
EXCELLENT PROPERTIES FOR VVM 500:
•Coil for hot water
There is a stainless steel hot water coil integrated in the
indoor module. The water in the coil is heated by the hot
water in the surrounding tank.
•Buffer vessel
There is a buffer vessel integrated in the indoor module
that equalises the temperature of the water that is sent
out in the climate system.
•Scheduling the indoor comfort and hot water
Heating and hot water can be scheduled for each day of
the week or for longer periods (vacation).
•Large display with user instructions
The indoor module has a large display with easy-to-under-
stand menus that facilitate setting a comfortable climate.
•Easy to install
The indoor module (VVM 500) is easy to install together
with a compatible NIBE air/water heat pump. When in-
stalling together with NIBE air/water heat pump, the heat
pump’s values can easily be read off from the indoor
module’s display.
•External heat source
VVM 500 is prepared for easy connection to a solar panel
installation and/or oil/gas/ wood fired boiler and district
heating.

Installation function
An air/water heat pump installation uses the outdoor air to
heat up a home. The conversion of the outdoor air’s energy
into residential heating occurs in three different circuits.
From the outdoor air, (1) , free heat energy is retrieved 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) .
NIBE VVM 500Chapter 2 | The heating installation – the heart of the house6
The heating installation – the heart
of the house

Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s evaporat-
or. Here, the air releases the heating energy to the refri-
gerant and the air's temperature drops. The cold air is
then blown out of the heat pump.
B
Refrigerant circuit
A gas circulates in a closed system in the heat pump, a
refrigerant, which also passes the evaporator. The refri-
gerant has a very low boiling point. In the evaporator the
refrigerant receives the heat energy from the outdoor
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 temperat-
ure increases considerably, from 0 °C to approx 80 °C.
D
From the compressor, gas is forced into a heat ex-
changer, condenser, where it releases heat energy to
the indoor module, 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 refri-
gerant 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 indoor module's water, the
heating medium, which is heated to 55 °C (supply tem-
perature).
G
The heating medium circulates in a closed system and
transports the heated water's heat energy to the house
radiators/heating coils.
H
The indoor module's integrated hot water heater is in
the boiler section. The hot boiler water heats the hot
water.

EXTERNAL INFORMATION
When the indoor module 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 indoor
module). The information window can display different types
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 front hatch of
the indoor module door is opened.
Status lamp
The status lamp indicates the status of the indoor module:
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 35.
