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).
The temperatures are only examples and may vary
between different installations and time of year.
Outdoor air
A The outdoor air is sucked into the heat pump.
B 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 temperature
drops. The cold air is then blown out of the heat pump.
Refrigerant circuit
C 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.
D 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 0 °C to approx 80 °C.
E 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.
F 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
G 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).
H The heating medium circulates in a closed system and transports the
heated water’s heat energy to the house radiators/heating coils.
I The indoor module’s integrated charge coil is placed in the boiler
section. The water in the coil heats up the surrounding domestic hot water.

Maintenance of VVM S320
Regular checks
Your installation should be checked and serviced annually by qualified
personnel. This is to ensure the continued efficient operation of VVM S320,
and for the warranty to remain valid during the warranty period.
All servicing must be carried out by a person competent for the job.
If anything unusual occurs, messages about the malfunction appear in the
display in the form of different alarm texts.
SAFETY VALVE
VVM S320 has two safety valves, one for the water heater and one for the
climate system. The water heater’s safety valve is fitted by the installer.
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 inspection panel on the front.
Perform the checks as follows:
- Open the valve.
- Check that water flows through the valve.
- Close the valve.
- Check the system pressure, top up if required.
NOTE
Do not remove or adjust any components that are part of this pressurised water
heater. Contact your installer!
NOTE
If this pressurised water heater develops a fault, e.g. a flow of hot water
from the overflow pipe, turn the heat pump off and contact your installer.
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 information.
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:
- Turn off the power supply to the indoor module.
- Vent the indoor module via the vent valves and the rest of the climate system via the relevant vent valves.
- Keep topping up and venting until all air has been removed and the pressure is correct.
The climate system may require topping up after venting.
Saving tips
Your installation produces heat and hot water. This occurs via the control
settings you made.
Factors that affect the energy consumption are, for example, 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). This is important, as fully or partially closed thermostat valves slow the flow in the climate system, which results in VVM S320 working at a higher temperature. This in turn can lead to increased energy consumption.
- You can lower the operating cost when away from home by scheduling selected parts of the system. This is done in menu 6 – “Scheduling”.
- If you select “Small” in menu 2.2 – “Hot water demand”, less energy is used.
- You can influence the energy consumption by connecting the indoor module to different supplements such as solar, gas or oil.
Disturbances in comfort
In most cases, VVM S320 notes a malfunction (a malfunction can lead to
disruption in comfort) and indicates this with alarms, and instructions for
action, in the display.
Info-menu
All the indoor module’s measured values are gathered under menu 3.1 –
“Operating info” in the indoor module’s menu system. Examining the values in
this menu can often make it easier to identify the source of the fault.
Manage alarm
In the event of an alarm, a malfunction has occurred
and the status lamp shines with a steady red light. You receive information
about the alarm in the smartguide on the display.
ALARM
In the event of an alarm with a red status lamp, a malfunction 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 and try again” for the
installation to revert to normal operation.
If a white light comes on after selecting “Reset alarm and try again”, the
alarm has been remedied.
“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 compressor is not
in operation. In this case, any electric additional 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.
