9Chapter 3 | Indoor module's designNIBE™ VVM 500

General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
The system requires a low-temperature design of the ra-
diator circuit. At lowest dimensioned outdoor temperature
(DUT) the highest recommended temperatures are 55 °C
on the flow line and 45 °C on the return line, but VVM
500 can handle up to 65 °C.
Overflow water from the safety valve goes via overflow
cups to a drain so that hot water splashes cannot cause
injury. The entire length of the overflow water pipe must
be inclined to prevent water pockets and must also be
frost proof.
NIBE recommends installing VVM 500 as close to the heat
pump as possible for optimum comfort. For further in-
formation about the location of different components,
see section "Installation alternatives" in this manual.
NOTE
The pipe systems need to be flushed out before
the indoor module is connected so that any
debris cannot damage component parts.
Maximum boiler and radiator volumes
H
Internal volume in VVM 500
for calculating expansion vessel
is 500 l. The expansion vessel's
volume must be at least 5 %
of the system's total volume.
Example table
Volume Ex-
pansion ves-
sel (l)
Total
volume (l)
(indoor
module and
climate sys-
tem)
25500
35700
501000
The initial pressure of the pressure expansion vessel must
be dimensioned according to the maximum height (H)
between the vessel and the highest positioned radiator,
see figure. An initial pressure of 0.5 bar (5 mvp) means
a maximum permitted height difference of 5 m.
If the standard initial pressure in the pressure vessel is not
high enough it can be increased by filling via the valve in
the expansion vessel. The expansion vessel's standard
initial pressure must be entered in the check list on page
3.
Any change in the initial pressure affects the ability of
the expansion vessel to handle the expansion of the wa-
ter.
System diagram
VVM 500 consists of a hot water coil, immersion heater,
circulation pumps, buffer vessel, control system and is
prepared for use with solar panels. VVM 500 connects
to the climate system.
VVM 500 is designed for connection and communication
with F20XX/F2300. F20XX/F2300 and VVM 500 together
make up a complete heating installation.
F2300 covers most of the heating and hot water require-
ment down to -25 °C.
When it is cold outdoors F20XX/F2300 works with VVM
500 and if the outdoor air temperature falls below -25
°C all heating is carried out by VVM 500.

Installation alternative
VVM 500 can be connected in several different ways,
some of which are shown below.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the ac-
cessories used. See page 53 for a list of the accessories
that can be used with VVM 500.
Extra hot water heaters
Extra hot water heaters
The indoor module can be supplemented with an electric
water heater, if a hot tub or other significant consumer
of hot water is installed. A mixing valve is then installed
on outgoing hot water from the heater.
Water heater with immersion heater
Appropriate heater is COMPACT 100-300 for floor
mounting and EMINENT 35-100 for wall mounting.
If the heater is equipped with a valve connector Ø 15 mm
this should be replaced with a corresponding Ø 22 mm.

To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be

General
All electrical equipment, except the outdoor sensors,
room sensors and the current sensors are ready connected
at the factory.
႑Disconnect the indoor module before insulation test-
ing the house wiring.
႑If the building is equipped with an earth-fault breaker,
VVM 500 should be equipped with a separate one.
႑For the indoor module wiring diagram, see page 58.
႑Communication and sensor cables to external connec-
tions must not be laid close to high current cables.
႑The minimum area of communication and sensor
cables to external connections must be 0.5 mm² up
to 50 m, for example EKKX or LiYY or equivalent.
႑When cable routing in VVM 500, cable grommets
UB1and UB2, (marked in image) must be used. In UB1
and UB2 the cables are inserted through the indoor
module from the back to the front.

Otherwise the temperature limiter, thermostat
and the immersion heater can be damaged.
NOTE
Electrical installation and service must be carried
out under the supervision of a qualified electri-

Miniature circuit-breaker
The indoor module and a large proportion of its internal
components are internally fused by a miniature circuit
breaker ((FA1)).
Temperature limiter
The temperature limiter (FD1) cuts the current supply to
the electrical addition if the temperature rises between
90 and 100°C and can be manually reset.
Resetting
The temperature limiter (FD1) is accessible behind the
front cover. Reset the temperature limiter by pressing the
button (FD1-SF2) using a small screwdriver.
Caution
Check the temperature limiter and miniature
circuit-breaker. They may have tripped during
transportation.

Connections
NOTE
To prevent interference, unscreened communic-
ation and/or sensor to external connections
cables must not be laid closer than 20 cm to
high voltage cable when cable routing.
Power connection
VVM 500 must be installed via an isolator switch with a
minimum breaking gap of 3mm. Minimum cable area
must be dimensioned according to the fuse rating used.
Supplied cable (length approx 2 m) for incoming electricity
is connected to terminal block X1 on the immersion
heater card (AA1). The connection cable can be found
on the reverse of VVM 500 (see dimensions diagram be-
low).

Tariff control
If the voltage to the immersion heater disappears during
a certain period, there must also be blocking via the AU-
input, see "Connection options- Possible selection for

Outside sensor
Install the outside temperature sensor (BT1) in the shade
on a wall facing north or north-west, so it is unaffected
by the morning sun.
Connect the sensor to terminal block X6:1 and X6:2 on
the input card (AA3). Use a twin core cable of at least
0.5 mm² cable area.
If a conduit is used it must be sealed to prevent condens-
ation in the sensor capsule.
