5Chapter 1 | Important informationNIBE VVM S320

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) .
The temperatures are only examples and may vary
between different installations and time of year.

2 Installation function

Outdoor air
The outdoor air is sucked into the heat pump.
A
The fan then routes the air to the heat pump’s
evaporator. Here, the air releases the heating
energy to the refrigerant and the air's temperat-
ure 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 refrigerant 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 compressed, the pressure increases
and the gas's temperature increases consider-
ably, from 0 °C to approx 80 °C.
D
From the compressor, gas is forced into a heat
exchanger, 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 origin-
al temperature. The refrigerant has now com-
pleted 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 temperature).
G
The heating medium circulates in a closed sys-
tem and transports the heated water's heat
energy to the house radiators/heating coils.
H
The indoor module’s integrated charge coil is
placed in the boiler section. The water in the
coil heats up the surrounding domestic hot wa-
ter.

Regular checks
If anything unusual occurs, messages about the malfunc-
tion appear in the display in the form of different alarm
texts.
SAFETY VALVE
The water heater’s safety valve sometimes releases a
little water after hot water usage. This is because the
cold water, which enters the water heater, expands
when heated causing the pressure to rise and the safety
valve to open. The climate system’s safety valve must
be completely closed and must not normally release any
water.
The functioning of the safety valve should be checked
regularly. You can find the safety valve behind the inspec-
tion panel on the front. Perform the checks as follows:
1. Open the valve.
2. Check that water flows through the valve.
3. Close the valve.
4. Check the system pressure, top up if required.
CHECK PRESSURE
VVM S320 has a pressure gauge, which shows the
heating system pressure. The pressure should be
between 0.5 and 1.5 bar, but varies during temperature
changes. If the pressure drops to 0 or rises to 2.5 bar
frequently, contact your installer for troubleshooting.
FILLING THE CLIMATE SYSTEM
If the pressure is too low in the climate system, it needs
to be topped up. See the Installer Manual for more in-
formation.
VENTING THE CLIMATE SYSTEM
In event of repeated filling of the climate system, or if
bubbling sounds are heard from the indoor module, the
system may need venting. This is done as follows:
1. Turn off the power supply to the indoor module.
2. Vent the indoor module via the vent valves and the
rest of the climate system via the relevant vent
valves.
3. Keep topping up and venting until all air has been
removed and the pressure is correct.
The climate system may require topping up after vent-
ing.

5 Maintenance of VVM S320

Saving tips
Your installation produces heat and hot water. This oc-
curs via the control settings you made.
Factors that affect the energy consumption are, for ex-
ample, indoor temperature, hot water consumption, the
insulation level of the house and whether the house has
many large window surfaces. The position of the house,
e.g. wind exposure is also an affecting factor.
Also remember:
• Open the thermostat valves completely (except in
rooms where you want it to be cooler). The thermo-
stats slow the flow in the heating system, which
VVM S320 wants to compensate by increasing the
temperature. It will then work harder and consume
more energy.
• You can lower the operating cost when away from
the house by scheduling selected parts of the system.
This is done in menu 6 - "Scheduling".
• If you select "Hot water demand Small", less energy
is used.
NIBE VVM S320Chapter 5 | Maintenance of VVM S32014

In most cases, VVM S320 notes a malfunction (a mal-
function can lead to disruption in comfort) and indicates
this with alarms, and instructions for action, in the dis-
play.

VVMS320 has no contact with the outdoor temperature sensor. Calculated
flow line temperature is set to min. flow line. If a higher temperature is desired
then min. flow line can be temporarily changed in menu 1.30.4. Check the
connection to the outdoor temperature sensor and reset the alarm. If the alarm
recurs, select aid mode and contact your installer.
12°C 13.45 3 October
In the event of an
alarm, a malfunction
has occurred and the
status lamp shines
with a steady red
light. You receive in-
formation about the
alarm in the smart-
guide on the dis-
play.
ALARM
In the event of an
alarm with a red
status lamp, a mal-
function has occurred that VVM S320 cannot remedy
itself. On the display, you can see what type of alarm it
is and reset it.
In many cases, it is sufficient to select “Reset alarm”
for the installation to revert to normal operation.
If a white light comes on after selecting “Reset alarm”,
the alarm has been remedied.
It the red light is still on or if the alarm recurs, the cause
of the problem remains.
"Auxiliary operation" is a type of emergency mode. This
means that the installation attempts to produce heat
and/or hot water, even though there is some kind of
problem. This could mean that the heat pump’s com-
pressor is not in operation. In this case, any electric ad-
ditional heat produces heat and/or hot water.
Caution
Selecting "Auxiliary operation" is not the same
as correcting the problem that caused the
alarm. The status lamp will therefore remain
red.
If the alarm does not reset, contact your installer for
suitable remedial action.
Caution
You need the product's ((14 digit) serial number
for servicing and support.
Troubleshooting
If the operational interference is not shown in the display
the following tips can be used:
Basic actions
Start by checking the following items:
• Group and main fuses of the accommodation.
• The property's earth circuit breaker.
• Correctly set load monitor (if installed).
